1.0 INTRODUCTION

This report summarizes preliminary site characterizationactivities performed by AWD Technologies, Inc. at M.I. Holdings'facility in Jersey City, New Jersey. The objective of thispreliminary investigation was an initial evaluation of soil andgroundwater conditions at the site. Field investigations began onJune 29, 1987 and included the installation of monitoring wells. andthe chemical analysis of soil and groundwater samples.

2.0 BACKGROUND INFORMATION

The M.l. Holdings facility in Jersey City is located betweenWest Side Avenue and Route 440 near Carbon Place. The surroundingarea is a combination of industrial and mixed residential use. Thefacility consists of 22 buildings that occupy approximately 11 acres.A variety of chemical products were produced continuously at the sitefor approximately 90 years.

Mercury products were manufactured at this facil ity until 1977.In 1977 production of all products. except Flowco(R} (calciumstearate). was discontinued.

2.1 Geology

The bedrock beneath the M.I. Holdings site is the Triassic Newarkformation which consists of red sandstones and shale with occasionallayers of conglomerate. To the east of the property, the TriassicPalisade Diabase forms a linear hill that extends the entire length ofJersey City and eventually emerges to the north along the HudsonRiver.

NJIOI -1-

TIERRA-B-014888

AWDTechnologies, Inc.

The actual depth to bedrock at this site is unknown.(1974) estimates that the depth to bedrock in this area is200 ft. The slope of the bedrock surface beneath the sitedips from east to west.

Lovegreen160 ft togenerally

Bedrock is overlain by stratified glacial drift and fluvialdeposits that consist of reddish brown silty sand.

2.2 Hydrogeology

Review of IDcaI geography suggests that groundwater probablyflows east to west across the site from the topographic high of thePalisade Diabase towards the Hackensack Meadows.

3.0 FIELD INVESTIGATIONS

3.1 Soil Borings and Monitoring Well Installation

Three pairs of clustered monitor wells were installed betweenJune 29, 1987 and July 7, 1987. Each cluster consists of one shallowand one deep 4-in. 0.0. PVC well. Shallow monitoring wells arescreened in the unconfined aquifer, and are generally completed 10 ftbelow grade. Deep wells were installed to a maximum depth of 50 ft.Well construction details are summarized on Table 1.

Figure 1 shows the location of the three well clusters installedby AWD Technologies at the plant. MW-IA and MW~IB were installed inthe northeast corner of the property and were expected to be on theupgradi ent side of the property. Clusters MW-2At MW-2B and MW-3At

MW-3B were installed along the western edge of the property and wereexpected to be on the downgradient side of the property. The

NJI01

TIERRA-B-014889

AWDTechnologies, Inc.

elevation of the wells was surveyed to the nearest O.OI-ft by HowardF. Greenspan Associates, a New Jersey licensed surveyor.

Drilling was performed by the E~stern Drilling Company ofWoodbury Heights, New Jersey using a George E. Failing 1250 Holemasterrig. The drilling was inspected in the field by a geologist,Mr. Paul Kareth, who also prepared the boring logs and monitor wellinstallation reports. Water rotary techniques and drag bits were usedto advance the boreholes, except where sediment characteristicsrequired the use of drilling mud to maintain an open hole.Specifically, mud was used during the first 14 ft of drilling at MW-IBand throughout the drilling of MW-3B where fluid loss dictated the useof mud to maintain an open hole. Split-spoon soil samples werecollected during well installation. Continuous samples were collectedto the top of the water table, and at 5-ft intervals thereafter.

Throughout the drill ing, air qual ity was monitored with an HNU(11.7 EV probe) and a mercury vapor analyzer both at the borehole andin the breathing zone.

All monitor wells were completed using 4 in. diameter flushthreaded PVC casing and .020-in. machine-slotted. 4-in.-diameter PVCscreens. Five feet of screen was installed in shallow wells, and 10feet in deep wells. A filter pack consisting of No.1 Jesse MarieSand and was placed 1 ft to 2 ft above the top of the screen. Thiswas followed by a 2-ft thick layer of bentonite pellets. Theremaining annular space was filled with a cement/bentonite slurry.Monitor well details are shown on Figure 2.

A relatively impermeable soil layer was encountered 11 ft belowgrade in MW-IB. This boring was reamed to 12-in.-diameter and an8-in.-diameter steel outer casing was set to a depth of 14 ft (i.e.,

NJ101 -3~

TIERRA-B-014890


3 ft below the top of the relatively impervious soil layer). Theannular space between the borehole and casing was filled with acement/bentonite slurry and allowed to set overnight before drillingcontinued.

Split-spoon samples were collected during the drilling of monitorwells MW-IB; MW-2B and MW~3A. The samples were collected continuouslyto the top of the water table in the shallow wells and at 5-ftintervals below the water table in the three deep monitor wells MW-IB;MW-2B, MW-3B.

Soils were examined in the field for evidence of contamination byvisual inspection and head space analysis with an HNU and a mercuryvapor meter. There were no indications in the field that any of thesoils collected contained contaminants. In the absence of fieldevidence, the soil sample collected from immediately above the watertable was selected for laboratory analysis.

Descriptions of the soils encountered during drilling arepresented on the boring logs included in Appendix A. Appendix Bcontains monitoring well installation reports.

3.2 Monitoring Well Development

Monitoring wells were developed as each cluster was completed.MW-IA and MW-IB were developed with air. whereas the other four wellswere developed using a submersible pump. A steady flow rate wasmaintained in MW-2B and MW-3B during development. MW-2A and MW-3Awere pumped dry several times during development because the minimumpump rate of 5 GPM resulted in evacuation of the casing.

NJIOI -4-

TIERRA-B-014891

AWU Technologies, Inc.

Each well was developed for 30 to 45 minutes or until a silt freedischarge was achieved. A silt·free discharge could not be obtainedfrom MW-3A due to the slow recharge of that well.

3.3 Groundwater Sampling

Groundwater samples were collected from all of the monitoringwells on three occasions: July 27 and 28, 1987; September 23, 1987;

and October 16, 1987.

The first round of samples consisted of unfiltered samplesanalyzed for priority pollutants plus a library search for 40additional tentatively identified compounds. Filtered groundwatersamples were collected and analyzed for priority pollutant metalsduring the next two rounds. Filtered samples were collected toevaluate the influence of suspended particles on the analyticalresults for metals.

laboratory analyses were performed by YWC, Inc. t of Monroe, CTand Whippany, NJ. YWCI is a NJDEP certified laboratory.

The protocols used to collect soil and groundwater samples atthis site were consistent with NJDEP guidance contained in the DraftECRA Sampl ing Plan Guide dated 6 June 1986, and the field samplingprocedures manual of June 1986. laboratory analyses were reported atNJDEP's Tier II QA level.

A decontamination area was established to clean purging eqUipmentbetween monitoring wells. Plastic sheeting was laid out to preventsampling equipment from contacting the ground. Alconox soap andpotable water were used to clean sampling equipment between wells.

NJ10l -5-

TIERRA-B-014892

AWD Technologies, Inc.

The three deep wells (MW-IB, MW-2B and MW-3B) were purged of aminimum three casing volumes of water using a submersible pump.Alconox and potable water were used to wash the pump. Approximately30 gallons of potable water were flushed through the pump afterpurging each monitor well.

The three shallow wells (MW-IA, MW·2A and MW-3A} were purgedusing a centrifugal pump and dedicated black PVC hose. The shallowwells were pumped dry and allowed to recharge for 2 hours, and thenpumped dry a second time before sampling.

Each well was sampled with a laboratory-cleaned, dedicated bailerconstructed of stainless steel tubing with teflon check valves.

The volatile organic vials were filled first. The remainingcontainers were filled in rotation to avoid developing a stratifiedsample. Samples were not filtered in the' field during the first.samp1in9 event. Consequent ly, the measured concentration of metalsincluded both dissolved metals and metals attached to particulates inthe sample. Subsequent samples submitted to the laboratory for metalsanalysis were filtered in the field using a 40 micron milliporefilter.

A field blank was collected each day by pouringlaboratory-supplied distilled water into a clean bailer, and thentransferring the water to the appropriate containers. A trip blankalso accompanied each day's samples, when analysis included volatileorganic compounds (VDCs).

All samples were transported directly to York laboratories inWhippany, New Jersey at the end of each day. Cha in -of-custody was

NJIOl

maintained throughout the sampling period, and is documented in thelaboratory reports included in Appendix C. This Appendix is boundseparately, and divided into two parts, because of its size.

4.0 DATA ANALYSIS AND RESULTS

4.1 Site Geology

Information included on boring logs (Appendix A) indicates thatthe site is underlain by approximately 10 ft of man-made fill whichoverlies at least 50 ft of natural soil deposits. The fill consistsmainly of sand with some construction debris. The fill on the easternside of the site overlies reddish brown silty sands of glacial orfluvial origin. A layer of peat and organic silt was encountered at adepth of 8 ft to 10 ft, indicating that the Hackensack Meadowsprobably extended onto the site along the western boundary of thesite. The eastern extent of the marshland is unknown. Reddish brownsilty sands were encountered below the marsh deposit.

The soil borings were terminated at a maximum depth of 50 ft.Bedrock was not encountered in any of the borings.

4.2 Site Hydrology

Water level measurements (Table 2) were used to estimategroundwater flow patterns at the site. Static water levelmeasurements from shallow and deep wells indicate that at least twowater bearing zones are present beneath the site. The upper waterbearing zone is under water table conditions, and groundwater isgenerally encountered within 10 ft of the ground surface. The deeperwater bearing zone occurs under confined or semi-confined conditions,and at the western end of the property 1s separated from the shallowzone by the marsh deposits.

NJ101 -7-

TIERRA-B-014894

AWDTechnofogles, Inc.

Groundwater elevations in shallow wells are uniformly higher thanthe deeper wells (Figure I). The differences in water elevationsbetween shallow and deep wells indicate a potential for downwardvertical movement of groundwater.

Plant north is defined on Figure 1 and our discussions of flowdirections are referenced to plant north. The water level data areinsufficient to develop a contour map of the piezometric surface dueto the limited number of observation points. In general, water levelmeasurements from both the shallow and deep monitor wells indicatethat groundwater flows predominately from east to west across thesite. A maximum gradient was calculated based on water elevations "atthe three well cluster locations. TIlemaximum' calculated gradient forthe shallow water-bearing zone was 0.009 and the maximum gradient forthe deep zone was 0.007. The components of gradient in thenorth-south and east-west directions, and the direction of flow are asfollows:

Gradient. F1ow Direct ion

Shallow wellsDeeper wells

fast-West.008W.006W

North-South.003N.0025

It should be emphasized that these calculated gradients provide only ageneral indication of the direction of groundwater flow. Water levelobservations at three points are the minimum number required to definethe general direction of flow~ and assume that the water table is aflat plane. This is most likely an oversimplification of actualconditions in the field.

4.3 Results of Chemical AnalYais

Measurements of pH, electrical conductivity and temperature wereobtained in the field at the time of groundwater sampling. Theresults of these measurements are shown in Table 2. The pH at monitorwell cluster 3 is quite high (about 10 and 11) in both the shallow anddeep wells. The pH at monitor well clusters 1 and 2 is about neutral(6.5) in the shallow wells and quite high (about 10) in the deeperwells.

Electrical conductivity is consistently higher in the deep wells.MW-IA had the lowest conductivity (111 umhos/cm) and MW-IB had thehighest (SOO umhos/cm). HNU readings of the atmosphere in eachmonitoring well indicate that only MW-3B contained va vapors abovebackground levels. The HNU reading of 7 ppm for MW-3B is .corroboratedby laboratory analysis of groundwater from this location.

laboratory analyses were performed on one soil sample from eachcluster location, and on groundwater samples collected from each well.First round analyses included priority pollutants plus forward librarysearch for both soil and groundwater. SUbsequent analyses werelimited to priority pollutant metals on groundwater samples.Analytical results for the last round of samples were received onOctober 26, 1987.

Analytical results are summarized on Tables 3 through 6.Complete laboratory reports are included in AppendiX C. Elevatedconcentrations of volatile organic compounds and some metals weredetected in groundwater collected from MW-3B. Soil from MW-3A, whichis adjacent to MW-3B, contained chromium and nickel in significantconcentrations. Soils and groundwater analyzed from elsewhere at thesite showed little evidence of contamination.

NJIOI ~9-

TIERRA-B-014896

AWD Technologies, Inc.

The presence of high chromium and nickel concentrations in soilat the site may be attributed to the use of contaminated fill, acommon problem in Jersey City.

The monitoring wells were sampled and analyzed for prioritypollutant metals on two occasions after the first sampling event.Samples collected during events two and three were filtered in thefield to remove any suspended solids that might be present. Filteringsignificantly reduced the observed concentration of metals ingroundwater.

The most significant concentrations of VOCs were detected ingroundwater collected from MW-3B. MW-3B is a deep well which contains11 ppm of trichloroethylene. MW-3A, the companion shallow well,contains several organic compounds but in the low ppb range. The highconcentrations of VOCs in deep well MW-3B, and their virtual absencein other wells at the site suggest one of the following:

• a contaminant source exists at the site, and a pathwayexists between the shallow and deep water bearingzones; or

• a contaminant source exists off site and it is beingtransported to M. I. Holdings' property by groundwaterflow.

5.0 CONCLUSIONS AND RECOMMENDATIONS

5.1 Conclusjons

The results of this investigation indicate that soil andgroundwater in the vicinity of the well cluster Number 3 arecontami nated with metal sand organic compounds. The elevated

NJIOI -10-

TIERRA-B-014897


concentrations of chrome and nickel in the soil may be attributed tothe use of contaminated fill at the site. a common problem in JerseyCity.

The source of vacs detected in MW-3B is not known at the presenttime. This is due in part to open questions regarding the directionof groundwater flow at the site.

5.2 Recommendations

AWD Technologies proposes the following activities be performedat the site as the next step toward defining subsurface conditions,hydrogeo logy. soi1 and groundwater contamination. and contaminationsources.

• Install two additional well c1usters on either side of .MW-3. This will provide better definition of theextent of vacs in groundwater. and may provide someinformation on the direction of the source.

• Perform a soil gas survey to assess the possibil itythat a source of vacs is present in soil at the site.

• Install a network of shallow and deep piezometers atthe site to better define vertical and horizontalgroundwater gradients and establish the pattern ofgroundwater flow across the site.

We will prepare a work plan describing these work items in moredetail, when requested by M.l. Holdings.

1.0 INTRODUCTION

1.1 Purpose

This Offshore Investigation Results SummaI)' Report represents a compilation of

the results of sediment chemistry and physical testing of sediments performed as pan of

the offshore investigation activities conducted between October 2003 and January 2004

in the Hackensack River in the vicinity of Study Area 7 (hereafter referred to as "SA 1',

or the "Site") located in Jersey City, New Jersey. Offshore investigation activities

included sediment sampling, field surveys, pore water characterization, water column

characterization, and geotechnical characterization of the sediment. The field work

discussed herein was implemented in compliance vvith two stipulated Immediate Action

Orders entered into by the parties pursuant to the judgment entered by the United States

District Court of New Jersey in Interfaith CommWlity Organization, et. aI. v. Honeywell

International et aI (Civil Action No. 95-2097 DMC, May IS, 2003). In particular, the

field activities summarized herein were specified in the Sediment Sampling Plan

(Immediate Action Stipulation Item 13) and the Bathymetric and Waterside Geophysical

Survey Plan (Immediate Action Stipulation Item 20) contained in the court order.

The chemical data included in this report have been independently reviewed and

validated by VALIDAT A, LLC under contract to Honeywell. All chemical data collected

during the offshore investigation was evaluated and validated according to the Standard

Operating Procedures (SOP) established by the New Jersey Department of Environmental

Protection (NJDEP 2001), The data presented in this report supersede the preliminary

results reported periodically by Honeywell to The Louis Berger Group previously. The

procedures used during implementation of the field work are summarized in the Offshore

Investigation Post - Field Sampling Report October 2003 To January 2004 Activities,

Study Area 7, Jersey City, New Jersey (Parsons and ENVIRON 2004).

1.2 Site Description

A si te map is provided in Figure I. The Study Area 7 site ("Site") is a 34-acre

parcel located on Route 440 in Jersey City, New Jersey. The Site includes three separate,

contiguous sites:

PARSONS Page I ENVIRON

TIERRA-B-014919

• Roosevelt Dnve-In SIte (NJDEP SIte 115),

• Trader Horn Site (NJDEP Site 120),

• Clean Machine Car Wash Site (NJDEP Site 157).

The Site is primarily a vacant [at, although the Trader Horn facility is still in

operation. All portions of the site have some form of cover: the eastern portion of the site

is paved with asphalt; the western portion was capped with a PVC cover and overlain

with gravel as an Interim Remedial Measure (IRM); and the middle of the site still

contains a concrete slab that was fonnerly the foundation for the Valley Fair department

store. With the exception of Trader Horn, no buildings exist on the property.

The site is bordered on the north by the Jersey City Incineration Authority

(NJDEP Site 087), the Jersey City Incineration Authority Well (NJDEP Site 088); on the

east by Route 440; on the south by the Roosevelt Bowling Lanes (NJDEP Site 124),

Delphic Consolidated (NIDEP Site 125), ABF Trucking (NJDEP Site 140), Old

Dominion (NJDEP Site 134), and Degen Oil (NIDEP Site 073); and on the west by the

Hackensack River. The Site is currently vacant but was formerly used for commercial

purposes SA 7 is surrounded by a perimeter security fence on three sides and a wooden

bulkhead along the waterfront adjoining the Hackensack River. Surrounding land use is

industrial and commerci aL

TIERRA-B-014921

2.0 RESVL TS OF BATHYMETRIC, GEOPHYSICAL, AND HYDRODYNAMIC

FIELD SURVEYS

2.1 Bathymetric Surveys

A two-person field team of Ocean Surveys, Inc. (OSI), operating under the

direction of an American Congress on Surveying and Mapping (ACSM) certified

hydrographer, conducted the bathymetric surveys. The surveys were performed in

accordance with the United States Army Corps of Engineers' (ACOE) Engineering

Manual EM 1110-2-1003 for Hydrographic Surveys (EM 1110-2-1003) for navigation

and dredging support in soft bottom materials. Bathymetric survey data were co fleeted

from the vicinity of the Site and surrounding offshore areas between October 17 and 22,

2003. The results of the bathymetric survey are presented in the Honeywell SA 7 Sediment

Program Bathymetric Survey, Jersey City, New Jersey report prepared by OSI (2004a).

2.2 Geophysical Survey

The geophysical survey was conducted between October 22 and 28, 2003. The

geophysical field team used remote sensing technology to collect sub-bottom

stratigraphy, magnetic field intensity, and geomorphology information. Geophysical

survey data were collected from the vicinity of the Site and surrounding offshore areas.

The geophysical field survey consisted of an integrated suite of remote sensing

technologies including sub-bottom profiling, magnetic field intensity mapping, and side

scan sonar imaging. The results of the geophysical survey are presented in the Honeywell

SA 7 Sediment Program Geophysical Survey, Jersey City, New Jersey report prepared byOSI (2004b).

2.3 Oceanographi<:/Hydrodynamic Characterization

Oceanographic and hydrodynamic survey data were collected from the vicinity of

the Site and surrounding offshore areas to collect water level, current velocity, and basic

water quality data for input to a sediment transport study and for evaluation and design of

sediment remediation options. The survey consisted of both an in situ program and a real-

time boat-mounted program using specialized field instrumentation. The in situ

instrument program consisted of measurement of current velocities, riverbed current


TIERRA-B-014922

velocities, sediment bed elevation, in situ river conductivity and temperature

measurements versus depth (CTD), and tidal variation around the Site As an adj unct to

the longer-term In situ instrument program, the oceanographic field team conducted a

pair of real-time boat-mounted current velocity and CTD-Turbidity profiling surveys over

nominal l3-hour tidal cycles along four cross-river transects. The results of the

oceanographic/hydrodynamic characterization are presented in the Honeywell SA 7

Sediment Program OceanographiC Survey, Jersey City, New Jersey report prepared by

OSI (2004c).

2.4 Groundwater Upwelling Study and In Situ Testing

The groWldwater upwelling study was conducted to obtain supporting data for the

groundwater investigations being conducted onshore at the Site. Specifically, the purpose

was to obtain data on potential areas of groundwater to surface water seepage in the

immediate vicinity of SA 7. Because the installation of pennanent piezometers in the

riverbed was not possible, the investigation utilized a Trident Probe system to collect

specific conductance and temperature measurements as indirect measures of potential

areas of groundwater upwelling. In addition, hand penetrometers were inserted into the

sediments to evaluate the bearing capacity of the sediments and vane shear tests were

conducted to evaluate the undrained shear strength of the sediments in the vicinity of the

Site. The results of the groundwater upwelling study and in situ testing are presented in

the Honeywell SA 7 Sediment Program Vibratory Coring, Trident Probing, Hand

Penetrometer and Vane Shear Investigation, Hackensack River, Jersey City, New Jersey

report prepared by 051 (2004d).


TIERRA-B-014923

3.0 SEDIMENT CHEMICAL CHARACTERIZATION RESULTS

Sediment grab and core sampling was conducted from the vicinity of the Site and

surrounding offshore areas (Figures 2A, 28, and 3). The field sampling procedures used

are documented in the Offshore Investigation Post - Field Sampling Report October 2003

To January 2004 Activities, Study Area 7, Jersey City, New Jersey (parsons and

ENVIRON 2004). A total of 1,429 surface and subsurface sediment samples were

collected and analyzed for 212 chemicals and 8 physical parameters, including:

Section 5.1 of this report).

3.1 Data Validation

YALIDA TA, LLC evaluated and validated the analytical data according to the

Standard Operating Procedure (SOP) established by the New Jersey Department of


TIERRA-B-014924

Environmental ProtectIOn. During the data validation process, the laboratory reports were

reviewed and quality assurance/quality control parameters were evaluated (where

applicable) as described in the data validation SOP (NJDEP 2001). The following

qualifiers were used where applicable:

• "R" indicates that the reporting limit or sample result has been determined to be

Wlusable due to a major deficiency in the data generation process. The data should

not be used for any qualitative or quantitative purposes.

• "f' indicates that the concentration should be considered approximate. This

qualifier indicates that the data validation process identifies a deficiency in the

data generation process.

• "ur' indicates that the sample-specific reporting limit for the analyte in this

sample should be considered approximate. This qualifier is used when the data

validation process identifies a deficiency in the data generation process.

• "B" indicates that detectable levels of the analyte were found in the associated

method blank.

3.2 Summary of Chemicals Detected

Summaries of the chemicals detected in sediment are presented in Tables 1, 2, and

3. The data tables include for each chemical the frequency of detection, the concentration

range, and the average detected concentration in sediment. In addition to the summary

statistics, the frequency of exceedance of chemical screening criteria established by New

Jersey Department of Environmental Protection and the National Oceanic and

Atmospheric Administration (NJDEPfNOAA) are also shown. Table I presents a

summary of chemicals detected in sediment samples collected at all depths of sampling in

the vicinity of SA7. Table 2 presents a summary of chemicals detected in sediment

samples from 0 to 0.5 feet below the sediment surface in the vicinity of SA7. Table 3

TIERRA-B-014925

3.3 Cross-Sections of Sediment Depths in the Hackensack River Adjacent to SA 7

Offshore sediment borings were drilled between November and December 2003

at a total of 41 locations in the vicinity of Study Area 7 for physical and chemical

characterization of river sediments. Sediment cores were collected using piston and

vibracoring methods at 33 of the 41 locations and deep geotechnical borings were drilled

using rotary drilling techniques at the remaining eight locations. Of the 33 sediment

coring locations, 26 were completed to a nominal depth of 10 feet below the sediment

surface (or "mudline") and seven were completed to depths greater than 10 feet (i.e., as

great as 17 feet) below the mudline. The deep gootechnical borings were typically drilled

approximately 20 feet into bedrock (i.e., a total depth of approximately 120 feet below

the mudline) The boring locations are shown on Figure 4.

Unconsolidated sediments consisting primarily of clays, silts and sands were

encountered in the upper 25 feet. Deposits found deeper than 25 feet are discussed in the

Subsurface Investigation, Study Area - 7 (Daylin-Grace Site), Jersey City, New Jersey

report prepared by Mueser Rutledge Consulting Engineers (l\1RCE) dated April 15,2004

(MRCE 2004). Draft sediment core boring logs were previously included in the Offshore

Investigation Post - Field Sampling Report October 2003 To January 2004 Activities,

Study Area 7, Jersey City, New Jersey (Parsons and ENVIRON 2004) and deep

geotechnical boring logs were included in the Subsurface Investigation report (MRCE

2004). Subsurface deposits encountered at shallow depths (i.e. upper 25 feet) include:

• Stratum D, Grey to Black Peat and Organic Clay: Typically dark grey organic

clay and clayey silt, scattered fine sand laminations, very loose to loose.

• Stratum SI, Grey Sand: Typically light to medium grey fine to medium-grained

sand, trace coarse sand and gravel, trace organic material, scattered laminations of

fine sand or silt, generally dense.

• Stratum RC, Reddish Brown Silty Clay/Clayey Silt: Typically reddish bro\Vll silty

clay and clayey silt, trace silty sand, dense to very dense.

Cross-sections showing the different shallow subsurface deposits in the sediment

and total chromium concentrations have been prepared for each cross-sections. Figure 4


TIERRA-B-014926

shows the locations of the cross-sections offshore from the Site. Sediment cross-sections

extending parallel to the waterfront bulkhead at the Site are shovm in Figures 5A through

5E. Sediment cross-sections extending perpendicular to the waterfront bulkhead are

shovlITIin Figures 5F through 5K.

3.4 Metals

3.4.J Total Chromium and Chromium VI

Total chromium and chromium VI in sediment samp[es were analyzed by

Columbia Analytical Services, Inc. (Columbia), Total chromium was analyzed using

United States Environmental Protection Agency (EPA) Method 601OB. Chromium VI

analyses were conducted by two analytical methods, EPA Methods 7l96A and 7199,

folloVving extraction by two different methods (NIDEP and EPA). Table 4 presents the

analytical results of chromium and chromium VI in sediment. Summaries of chromium

and chromiwn VI concentrations in sediment are presented in Tables 1,2, and 3

Total chromium was detected in all sediment samples collected, with a

concentration range of 3.9 milligrams per kilogram (mg/kg) to 33,500 mglkg and an

average concentration of 534 mg/kg. Figures 6A through 6X show the concentration of

chromium in sediment in the vicinity of SA 7. Of the 421 total chromium samples

collected, 280 samples exceeded the NJDEPtNOAA Effects Range Low (ERL) screening

criterion of 81 mglkg, 137 samples exceeded the NJDEPINOAA Effective Range

Medium (ERM) screening criterion of 370 mg/kg, and 288 samples exceeded the NOAA

Apparent Effects Threshold (AET) of 62 mg/kg.

Figures 7A through 7E display the estimated median chromium concentration in

sediment in the vicinity of SA 7 using a three-dimensional interpolation method. These

figures show the offshore areas where total chromium concentrations are below the

screening criteria, or exceed the AET, ERL, and ERM benchmarks.

Chromium VI concentrations in sediment are shown in Figures 8A through 8X.

Chromium VI was detected in 218 samples, with a concentration range of 0.5 mglkg to

57 mg/kg.

tributyltin, and tetrabutytin were detected in sediment samples with a concentration range

of 1.9 micrograms per kilogram (ug/kg) to 16 uglkg.

3.7 Polychlorinated Biphenyls, Polychlorinated Dibenzodioxins and

Dibenzofurans, and Polybrominated Diphenyl Ethers

Polychlorinated biphenyls (PCBs), polychlorinated dibenzodioxins (PCDDs) and

dibenzofurans (PCDFs), and polybrominated diphenyl ethers (PDBE) analyses were

conducted by Alta Analytical Laboratory, Inc. (Alta) in EI Dorado Hills, California In

addition to measured concentrations, the Toxicity Equivalency Quotient (TEQ) of the

PCBs, PCDDs, and PCDFs was calculated to provide a single value normalized to the

toxicity of 2,3,7,8-TCDD for all dioxin-equivalent compounds contained in a given

sediment sample. The total TEQ was calculated by summing the product of the measured

concentration of each dioxin or PCB congener and its Toxicity Equivalent Factor (TEF)

using the dioxin-equivalent toxicity scheme for human exposure developed by the World

Health Organization (Van den Berg et al. 1998). The TEQ calculations include analytical

results of seven PCDD congeners, ten PCDP congeners and twelve coplanar PCB

congeners. In the calculation of PCB and PCDDIF TEQs, one-half of the detection limit

was used for non-detect samples.

3.71 PolychlOrinated Biphenyls

Total PCB analyses were conducted by Alta usmg EPA Method 8081 and

coplanar PCB analyses using EPA Method 1668. Table I I presents the analytical results

of PCBs in sediment. Summaries of PCB concentrations in sediment and their screening

criteria exceedances are presented in Tables I, 2 and 3. TEQ concentrations of PCBs

3.8 Other Parameters

Nitrogen ammonia, total organic carbon (TOC), and pH analyses were conducted

by STL-Edison using EPA Method 350.1-350,2, modified ASTM Method D 2579, and

EPA Method 9040B, respectively. Bulk density and percent solids analyses were

conducted by STI...-Edison and STI...-Vf, respectively. Table 14 presents the analytical

results of nitrogen ammonia, total organic carbon (TOC), bulk density, solids, and pH in

sediment.

3.9 Pore Water Characterization Results

Pore water, the water occupying the space between sediment or soil particles, was

extracted from sediment of the nine stations sampled for toxicity and bioaccumulation

testing. The isolation of pore water from these sediments occurred at the Site between

November II and 13, 2003, Total suspended solids (TSS), chromium, and metals in pore

water were analyzed by MEC Analytical Systems (MEC) in Calsbad, California and

STL-Edison. TSS results are presented in the Offshore Investigation, Sediment Toxicity

Characterization Report for November 2003 Sampling Activities, Honeywell Study Area

7, Jersey City, New Jersey prepared by MEC (2004). Table IS presents the analytical

results of total chromium and chromium VI in pore water. Table 16 presents the

analytical results of metals in pore water,

4.0 WATER COLUMN CHARACTERIZATION RESULTS

4.1 Total Suspended Solids

Water column samples for TSS analysis were collected in November and

December 2003 during the oceanographiclhydrodynamic survey operations. The results

of TSS in the water column are included in the oceanographic-hydrodynamic

characterization report entitled Honeywell SA 7 Sediment Program Oceanographic

Survey, Jersey City, New Jersey report prepared by OSI (2004c).

4.2 Chromium

A water column sampling event was also implemented to evaluate the potential

presence of chromium in surface water adjacent to the Site and in the identified reference

areas. On October 16, 2003, shallow surface water samples were collected for chromium

analysis from three locations near SA7 and from two locations in each of the three

targeted reference areas. figures 2 and 3 show the locations of water column samples in

the vicinity of Study Area 7 and the reference areas. All chromium grab water column

samples were submitted to Columbia for analysis of total chromium and chromium VI.

Total chromium was analyzed using EPA Method 60 lOB and chromium VI was analyzed

using EPA Method 7199. Table 17 presents the analytical results of total chromium and

chromium VI in water column samples.

5.0 GEOTECHNICAL CHARACTERIZATION RESULTS

5.1 Geotechnical ParameteI"s

To collect information on the physical sediment characteristics necessary both for

evaluating potential sediment remedies and in possible designing of near-shore structures (e.g.,

docks or shoring) to be used as part of the SA7 remedy, a number of sediment boring samples

were collected for geotechnical evaluation. Figure 2b shows the locations of sediment borings for

geotechnical characterization. The offshore geotechnical boring program was implemented

between December 3 and 23,2003 under the oversight of:MRCE. Table 18 presents the results of

the sediment geotechnical parameters, which included natural water content, liquid limit,

plasticity index, gradation (grain size), organic content, and specific gravity of the sediment

samples.

Core sediment samples were also obtained for standard oedometer (consolidation) and

permeability testing. The sediment samples were collected widl piston cores during November

and December 2003. However, these samples appeared to have been disturbed either as a result

of the coring, storage, or transportation procedures, and were considered too disturbed to obtain

meaningful consolidation and permeability results. MRCE has undisturbed sediment core

samples collected with a fixed piston from the shallow portions of the deep borings, GEO-l

through GEO-S, which can be used to run these tests. The locations of these borings are shown in

Figure 2B. ENVIRON requested the results of standard oedometer and permeability testing of

sediment borings (GEO-2. GEO-4, GEO-S, GEO-7, and GEO-8) from IvlRCE. The results of the

standard oedometer and permeability testing are shown in Table 19.

5.2 Self-Weight Consolidation/Column Settling

In addition to the geotechnical samples, surface sediment was sampled from three

locations for self-weight consolidation and column settling tests on November 22, 2003. The

self-weight consolidation/column settling test samples were submitted to Trident Tech Services,

Inc. (Trident) of Chesterton, Indiana for analysis. The results of the self-weight consolidation-

colulTU1settling tests are presented in the Sediment Testing Report - SA 7, Jersey City, New

Jersey report dated February 20, 2004 prepared by Trident (2004).


TIERRA-B-014932

5.3 Radiodating Analysis

To age-date different sediment depth intervals, sediment samples were collected from

certain sediment cores during the offshore sediment coring program for isotopic radiodating

testing and evaluating the depositional history of the offshore area near the Site and the stability

of the sediments. The radiodating samples were analyzed by Flett Research, Ltd. (Flett) of

Winnipeg, Manitoba. Canada for isotopic constituents using lead-210 (Ph-2l0) and cesium-137

(es-137) as indicator elements. Sediments to a depth of 10 em were also analyzed for bery IIium-

7 (Be-7), and a very limited subset of sample intervals was analyzed for radium-226 (Ra-226)

The radiochemistry results are presented in the Radiodating Analytical Report dated April 25.

2004 prepared by Flett (2004)

6.0 ECOLOGICAL TOXICITY STUDIES

6.1 Sediment Toxicity and Bioaccumulation Samples

Composite sediment samples for the analysis of toxicity were collected between

November 7 and II, 2003 A description of the sampling process was discussed in Section

3.7.2.1 of the Offshore Investigation Post - Field Sampling Report October 2003 To JanuQlY

2004 Activities, Study Area 7, Jersey City, New Jersey (Parsons and ENVIRON 2004). The

composite sediment toxicity samples were analyzed for total chromium, chromium VI, TAL

metals, AVS/SEM, sVOCs, PARs, pesticides, PCBs, PCDDlFs , PBDEs, and other parameters.

Results were compared to those from similar testing performed concurrently at three locations

elsewhere in the Hackensack River and upper Newark Bay. Bioassays were performed in

accordance with USEPA and us. Army Corps of Engineer test methods. The methods and

more detailed results of the sediment toxicity study are presented in the Offshore Investigation,

Sediment Toxicity and Benthic Injaunal Characterization Report jor November 2003 Sampling

Activities, Honeywell Study Area 7, Jersey City, New Jersey prepared by MEC (2004). Results

of the sediment toxicity samples were validated using the data validation method described in

Section 3.1 of this report and are shown in Tables 4 through 14.

6.2 Benthic Infaunal Smoyey

Sediment samples were collected offshore from SA 7 and in three reference locations to

determine the abundance and diversity of the benthic infaunal community in the sediment. The

benthic infaunal survey was performed in accordance with EPA methods. The methods and

results of the benthic infaunal survey are presented in the Offshore Investigation, Sediment

Toxicity Characterization Reponjor November 2003 Sampling Activities, HoneyweJl Study Area

7, Jersey City, New Jersey prepared by Iv.lliC (2004).

EXECUTIVE SUMMARY

Honeywell International Inc. (Honeywell) has completed an evaluation of remedial action alternatives toaddress chromium contamination for the portion of Study Area 5 proposed for redevelopment by NewJersey City University (NJCU or University). This portion of Study Area 5 is comprised of the followingsites:

Site NameFormer Baldwin SteelFormer MJ. HoldingsPortion of the Former Morris Canal Site

NJDEP Site No.90

184153

These sites are collectively referred to herein as the "Site", and encompass a total of approximately 14acres located in Jersey City, Hudson County, New Jersey (see Illustration I).

This combined Supplemental Remedial Investigation Report (SRIR), Remedial Action Selection Report(RASR), and Remedial Action Work Plan (RA WP) reflects Honeywell's concerted efforts to produce anintegrated remedial approach to the New Jersey City University site (a portion of Study Area 5),developed in close cooperation with and supported by the University. The approach selects a remedialtechnology based on the specific uses anticipated for the chromium impacted portions of the Site,consistent with the guidance in the Department's recently issued Chromium Directive (Policy). Theseuses fall into both the Residential and Commercial categories that are discussed in the Policy. Honeywelland NJCU have met numerous times to coordinate the remediation with the redevelopment, and haverecently formed ajoint team to continue this coordination through the life of the project.

This cooperative effort has resulted in a comprehensive approach to chromium remediation. This RA WPapplies a combination of remedial technologies that will fully protect human health and the environmentand effectively integrate the remediation with the redevelopment. This proactive approach 1) isencouraged by New Jersey's Brownfields Legislation, 2) fully meets both the spirit and intent of thePolicy, and 3) complies with the Technical Requirements for Site Remediation. We strongly believe thatthis approach is a model that demonstrates what can be achieved under the new Policy.

Working with the property owner, Honeywell has developed a viable and protective remedy forcontamination associated with both chromite ore processing residue (COPR) and sodium chromate. TheCaPR was likely used as fin on the Site and the sodium chromate likely resulted from housekeepingpractices associated with the adjacent, former Mutual Chemical site. The remedy supports the aggressiveSite redevelopment plan and schedule envisioned by NJCU.

The remedial approach presented herein was developed to align remediation solutions with NJCU's plansfor the property and is fuJly protective of human health and the environment. NJCU's redevelopment of theSite will result in both residential and commercial uses. Honeywell, following the guidance of the Policyand Technical Requirements for Site Remediation, has selected remedies that support the site uses. Forresidential uses, defined by the Residential Area of Concern (RAOq, excavation will be applied. Forcommercial uses, similarly defined by the Commercial Area of Concern (CAOq, both state of the artengineering controls and an innovative reactive wall (or permeable reactive barrier) will be applied (seelllustration 1). The combination of remedial approaches described in this document will ensure that:

• Chromium-impacted soil will be excavated in the RAOC;Chromium-impacted soil will be effectively isolated to prevent direct contact in the CAGC;Impacted groundwater will be addressed by focused source soil removal/treatment and in-situpermeable reactive barrier (PRB) treatment remedy;

• Prevention of re-contamination of excavation areas; and,• The Site will be restored quickly to productive use as part of a major redevelopment project benefiting

the surrounding community.

Honeywell supports the planned Site redevelopment because:

• It protects human health and the environment;• Quickly returns the Site to productive use;• Is consistent with the NJDEP's Policy; and,• Meets the objecti yes of the New Jersey Brownfields Legislation that encourages cleanup and reuse of

sites impacted by historical contamination.

NJCU fully supports Honeywell's approach and is ready to proceed with the Site development pendingreview fPld approval of this RAWP by the NJDEP. NJCU intends to request funding for theirredevelopment through the Environmental Infrastructure Trust Fund. Their goal is to submit an applicationto the Trust Fund in August, 2007 and that funding application requires an approved RA WP.

The components of the proposed remedial actions include:

• Excavation of soils containing hexavalent chromium above 20 mglkg to a depth of 20 feet (20/20) inthe Residential AOe. The Residential AOC extends to the nearest physical feature of the adjoiningCommercial AOC.

• Additional focused soil excavation in the Commercial AOC to provide clean utility corridors and tocoordinate the proposed capping system with proposed Site development features along Route 440.

• Engineering controls (cap) for the Commercial AOC where soils exceed 20 mglkg hexavalentchromium.

ES-2

TIERRA-B-015010

• Installation of an in-situ permeable reactive barrier (PRB) using a biological medium for the treatmentof residual impacted groundwater across the western portion of the Site.

• In-situ groundwater treatment system to reduce source concentrations on the adjacent Home Depot site,which is contributing to the deep aquifer contamination.

• Impermeable barrier and backfill liner systems to prevent recontamination of excavated areas frompotential upgradient sources.

• Institutional Controls (Deed Notice) for soils remaining with hexavalent chromium above 20 mg/kg.

• Institutional Controls for groundwater (Classification Exception Area [CEA]), if necessary.

The remedial approach described herein goes beyond what is required in the Policy for the RAGC byproviding for full excavation to 20/20. Treatment of the chromium impacted soils is allowed under thePolicy, but Honeywell has chosen to excavate all of the RAGC to 20/20, primarily to meet NJCU's schedulerequirements. The remedial approach also provides an added measure of protection for the CAGC byincluding a redundant groundwater protection system as a "belt and suspenders" approach. In addition tothe PRB, Honeywell will be installing piping that will enable a pump and treat system to be activated, ifnecessary.

The NJCU West Side Campus Expansion will serve to broaden the physical resources of the Universityand enable them to provide expanded learning opportunities for New Jersey residents, primarily fromHudson County. It will also provide attractive retail outlets and market rate housing that will help tocontinue the revitalization of Jersey City's west side. Honeywell's remediation plan will enable thisredevelopment to move forward quickly and with a fully protective remedy.

1.0 INTRODUCTION

1.1 PURPOSE AND SCOPE

This combined Supplemental Remedial Investigation Report (SRIR), Remedial Action Selection Report(RASR) and Remedial Action Work Plan (RA WP) was prepared by MACTEC Engineering andConsulting, Inc. (MACTEC) on behalf of Honeywell International Inc. (Honeywell) to address chromiumcontamination on the portion of Study Area 5 (SA-5) proposed for redevelopment by New Jersey CityUniversity (NJCU). This portion of SA-5 is comprised of sites designated as Baldwin Steel (NJDEP Site090), M.1. Holdings (NJDEP Site 184), and a portion of the Former Morris Canal Site (NJDEP Site 153)abutting Sites 090 and 184 (collectively referred to herein as the "Site"). This document addressesremedial investigation (Rl) requirements and proposes remedial actions for the Site in accordance withthe requirements of the Administrative Consent Order (ACO) and the New Jersey TechnicalRequirements for Site Remediation (Technical Requirements) (NJDEP, 2003).

Honeywell (formerly Allied Signal, Inc.) entered into an ACO with the New Jersey Department ofEnvironmental Protection (NJDEP) on June 17, 1993, to investigate and, if necessary, remediatechromium contamination at twenty-one (21) Sites referred to by the NJDEP as the Hudson CountyChromium Sites. The Sites are located in Jersey City, New Jersey, and are grouped into seven (7) StudyAreas. SA- 5 is comprised of five (5) contiguous Sites identified as follows:

• Ryerson Steel (Site 117)• Baldwin Steel (Site 090)• MI Holdings (Site 184)• Route 440 Vehicle Corporation (Site 079)• Fonner Morris Canal Site (Site 153)

A Remedial Action (RA) for soils has already been completed at the former Ryerson Steel site (Site 117but now conunonly referred to as the Home Depot site). This action was part of the redevelopment of theproperty as a retail shopping center. Previous investigations and remedial actions have also beenconducted on portions of Site 184 (MI Holdings). Previous investigation and remedial action activitieson the eastern portion of Site 184 were reported to NJDEP on December 1, 1992, and additional Sitecharacterization and remediation was completed in the western portion of Site 184, including excavationand off-site disposal of contaminated soils. These activities were documented in a report prepared byWoodward-Clyde Consultants dated August 30,1993.

RI activities have been substantially completed on the remaining Sites comprising SA-5. A reportentitled Draft Remedial Investigation Report (RIR) - Study Area 5, dated November 1999, prepared byTetraTech, Inc., documented the results of previous RI field activities on the five (5) sites comprisingSA-5 (TetraTech, 1999). The NJDEP provided comments on the RIR in a letter dated October 9, 2001,and Honeywell provided responses to the NJDEP review comments in a letter dated December 19,2001.An RIR Addendum with results of additional soil sampling performed on Site 090 (Baldwin Stee!) andSite 184 (MI Holdings) was submitted to the NJDEP in October 2004 (TetraTech, 2004).

A Remedial Investigation Work Plan (RIWP) Addendum for Shallow Groundwater was prepared byMACTEC and submitted to the NJDEP in March 2005. The results of the additional RI field activitiesare presented in this report. The additional RI activities were conducted to address NJDEP requirementsfor shallow groundwater in response to the NJDEP comment letter dated December 21,2004 on the RIR

TIERRA-B-015012

Addendum, and subsequent discussions including a meeting held on February 3, 2005 betweenrepresentatives of Honeywell and the NJDEP. Honeywell provided responses to the NJDEP commentson the RIR Addendum in a letter dated February 15,2005. Prior to field mobilization for the additionalRl activities in April 2005, a conference call was held between representatives of Honeywell and theNJDEP to discuss the proposed supplemental field activities. NJDEP provided preliminary verbalcomments on the RIWP during the conference call on April 8, 2005, and subsequently provided writtencomments in a letter dated June 3, 2005. Honeywell transmitted a letter dated July 1,2005, withresponses to the NJDEP review comments.

The RI has included a total of over 80 soil borings and analysis of over 700 samples for total andhexavalent chromium on the Site. Based on the RI soil data, the horizontal and vertical extent ofhexavalent chromium above the most stringent NJDEP Soil Cleanup Criteria of20 mglkg has beencharacterized and delineated.

This RASR/RA WP presents an evaluation of remedial alternatives and selected remedial actions toaddress chromium contamination, to be implemented as part of the Site redevelopment activities.Working with NJCU, Honeywell has developed a viable and protective remedy to address contaminationassociated with the historical placement of chromium-containing fill at the Site. Currently, an interimremedial measure (IRM) consisting of pavement and existing floor slabs serve as a cap to prevent directcontact with contaminated soils. NJCU plans to redevelop the land into a mixed-use facility, referred to asthe NJCU West Campus Development, consisting of student housing, retail, and other educational facilities.Under the current redevelopment plan, it is anticipated the existing pavement and building foundations willbe removed, and a remedy to address chromium contamination will be implemented.

The remedial approach takes into consideration the recently issued Chromium Policy (NJDEPMemorandum dated 2/8/07) and NJCU's redevelopment plan, which includes residential and commercialuses. Honeywell, following the guidance ofthe Chromium Policy, has selected remedies that address thesite uses. The components of the proposed remedial actions for chromium include:

• Pre~remediation activities including obtaining property access agreements; remedial design; andregulatory approvals including soil reuse plan approval (if necessary), soil erosion sediment control plan(SESCP) certification, and local construction permit approvals.

• Excavation of chromium-impacted soils in the Residential AGC (RAOC). Soils containing hexavalentchromium above 20 mg/kg in the RAOC will be excavated to a maximum depth of20 feet. As aconservative measure, Honeywell has extended the RAGC out from the footprint of residential usebuildings to the nearest physical feature of the adjoining commercial area (CAGC).

• Engineering controls for soils exceeding 20 mgikg in the CAGe. The engineering controls include acapping barrier with impervious geo-membrane liner, geo-composite drainage layer, and minimumtwo fect clean soil cover, or minimum I-foot clean soil and pavement cover.

• Additional focused soil excavation may be performed to provide clean utility corridors in connectionwith the proposed Site development and to coordinate the proposed capping system with proposedSite development features along Route 440. Soils excavated for utility corridors and grading for capinstallation will be re-used by consolidation and capping on-site.

TIERRA-B-015013

• Installation of an in-situ permeable reactive barrier (PRE) that will use biologically mediated reductionfor treatment of hexavalent chromium. The PRE will run primarily along the western border of the Site.

• Implementation of an in-situ groundwater treatment system to address residual source material on theHome Depot property (Site 117), which is contributing to the deep groundwater chromium plume. Animpermeable hydraulic barrier will be installed along the southern property line of the Site tohydraulically isolate remediated areas on the Site from "source area" groundwater on Home Depot.

• Installation of impermeable barrier and backfill liner systems to prevent recontamination ofexcavated areas from potential upgradient sources.

• Institutional Controls (Deed Notice) for soils above 20 mg/kg hexavalent chromium, includingmaintenance of existing engineering controls (e.g., concrete, pavement) and newly installed controlsduring the remedial action and Site redevelopment (e.g., engineered barrier, clean fill, paving).

• Post-remediation groundwater monitoring to evaluate chromium concentrations with respect to theNJDEP Groundwater Quality Standard (GWQS) of70 micrograms per liter (ugIL), and InstitutionalControls for groundwater (Classification Exception Area [CEAD, if necessary.

This RASRJRA WP addresses soils and shallow groundwater impacted by chromium contaminationabove applicable remediation criteria, and satisfies the Technical Requirements for Site Remediationwhile incorporating the objectives of New Jersey's Brownfields Program. While the NJCU final designand development work progresses, Honeywell will proceed with final engineering design activities. Theremedy for soils takes into consideration the current NJDEP chromium policy and current redevelopmentplans by NJCU. NJCU is in agreement with deed notice restrictions for the remedial approach in thisRAWP.

The proposed remedial actions for the portion of Site 153 (Former Morris Canal) abutting Sites 090/184(NJCU Property) include limited soil excavation as may be required for cap installation and for providingclean utility corridors to support the proposed Site development by NJCU. Honeywell has proposed tobuy this portion of the former Morris Canal from the Bayonne Municipal Utilities Authority (BMUA),and anticipates successful completion of this purchase in the next several months. At that point, as theproperty owner, Honeywell would agree to deed notice and institutional controls for this property.

The R1 data for the Site and data from the regional groundwater investigation being conducted under theoversight of a court-appointed Special Master for Study Area 7, demonstrate that shallow groundwaterconditions at the Site are not a source of the groundwater impacts in the deep groundwater zone. Furtherinvestigations and remedial actions for the deep groundwater zone are being addressed under separate workplan(s) subject to review/approval by the Special Master for Study Area 7. The Final GroundwaterInvestigation Report (GIR), for the regional investigation, was submitted to the Special Master and NJDEPon February 2, 2007 (HydroQual, Inc., 2007).

Based on the Final GlR and additional data collected at Site 117 (adjacent to Site 090), an in-situgroundwater treatment system is proposed by Honeywell to address the residual source on Site 117contributing to the regional groundwater contamination. The proposed groundwater treatment system isincluded with this RA WP for NJDEP review and approvaL

Surrounding land use isprimarily industrial and commercial and includes the former Ryerson Steel Site (Site 117 or HomeDepot site; currently occupied by a retail shopping center) located immediately south of Site 090(Baldwin Steel); Route 440 Vehicle Corporation (Site 079; currently occupied by a car dealership)located north of Site 184 (M.l. Holdings) on the opposite side of Carbon Place; the Former Morris Canal(Site 153) located along the western boundary of Sites 090 and 184 along Route 440; and commercialareas on the opposite side of West Side Avenue to the east. Further details regarding the subjectproperties follow.

Baldwin Steel (Site 090)The Baldwin Steel property is located at 500 Route 440, designated as Block 1286, Lots 5 and 60 on theJersey City tax maps. The property encompasses approximately 6.8 acres, currently owned by NJCU,and contains the concrete floor slab of one large building previously used for steel fabrication anddistribution.

The property consists of a rectangular parcel (approximately 1,000 feet long and about 300 feet wide)bordered on the north by M.L Holdings (Site 184), on the east by an inactive rail spur line and propertyoccupied by NJCU, on the south by a retail shopping center (Site 117; Former Ryerson Steel or HomeDepot site), and on the west by the Former Morris Canal (Site 153) and Route 440. With the exceptionof paved parking areas bordering Route 440 and a paved corridor along the south side of the property(between the former Baldwin Steel building and aforementioned retail shopping center), the property iscovered by the former building slab (estimated 650 feet long by 250 feet wide or 162,000 square feet).

The Baldwin Steel Site was previously used for storage, cutting and rolling of various types of steel (e.g.,aluminized, galvanized, cold-rolled, etc.), typically used for fabrication into ductwork. Tractor trailersdelivered raw materials via access from West Side Avenue and exited the facility at the western end ontoRoute 440. A rectangular office space was located at the rear of the plant and connected the ,plant to anirregularly-shaped storage building. The building was a large structure constructed of a concretefoundation, steel colunms, steel and wooden trusses, and corrugated steel siding. The office and storagebuildings were constructed of con'crete foundations and brick. The office building was a one-storystructure, while the storage building was two stories. No sub-grade floors or basements existed in thebuilding structures, with the exception of press pits located beneath some ofthe heavy equipment usedfor cutting and rolling. It is believed that the buildings were constructed prior to 1930.

Site utilities include electrical service, water, sanitary sewer, storm sewer, and fuel oil lines. All utilitiesare located underground with the exception of the electrical lines, which include both overhead andunderground lines. An underground water line which provides water to three hydrants on-Site is also

TIERRA-B-015016

located along the roadway on the south side of the former Baldwin Steel building. Potable and non-potable water entered the former office/storage building and the plant via lines from West Side Avenuein the northeast comer of the property. The sanitary sewer line ran along the interior of the plantbuilding and tied into a sanitary sewer line along Route 440.

The Baldwin Steel Site is surrounded by a chain-link fence ranging from four to eight feet in height.Access to the property is from three gates, one located at the rear of the facility which allows access fromWest Side Avenue and two located at the front of the property for access from Route 440. The entireproperty is either occupied by building floor slabs or is covered with paving. All areas on the site werepaved as a result of remedial action upgrades during an Interim Remedial Measure (IRM) completed in1990 by a contractor for Honeywell (formerly Allied Signal). The pavement on the east and south side(along the Former Ryerson Steel property boundary) of the building is uneven, possibly due to placementof underlying fill material in this area.

M.L Holdings (Site 184)The M.I. Holdings property is located southeast of the intersection of Carbon Place and Route 440,designated as Block 1286.5, Lots 1 & 2 on the Jersey City tax maps. The property encompassesapproximately seven (7) acres and was formerly an active chemical manufacturing facility. The propertyis currently owned by NJCU and occupied by several buildings, paved parking lots and landscaped areas.

The M.l. Holdings Site is bordered by Carbon Place to the north, Route 440 to the west, Baldwin Steel(Site 090) to the south, and property occupied by NJCU to the east. The majority of the property ispaved, with several small lawn areas and a chain-link fence around the perimeter of the property. TheSite contains three (3) buildings and paved parlGng lot areas. In 1993, Woodward-Clyde Associatescompleted a remedial action at the Site, which included excavation of mercury/chromium-impacted soils,building demolition, and asphalt capping. The paved areas are in good condition, with no evidence ofcracks or potholes leading to exposure to underlying fill soils. The property is surrounded by a chain linkfence approximately IO-feet in height, with access to the property from several entrance gates alongCarbon Place and from the eastern side of the property along West Side Avenue. Site physical featuresalso include overhead utilities (electrical lines) and underground utilities (gas, water, and sewer lines).

Former Morris Canal Site (Site I53)The Former Morris Canal site consists of a narrow strip of land located along the northbound lane ofRoute 440 between Carbon Place and Danforth Avenue, adjacent to former Ryerson Steel (Site 117),Baldwin Steel (Site 090), and M.L Holdings (Site 184). The property comprising the Former MorrisCanal is designated as Block 1289.5, LotE, currently owned by the BMUA, is approximately 1,500 feetlong by 20 feet wide, including about 700 feet adjacent to Sites 090 and 184. Utilities along the FormerMorris Canal site include storm and sanitary sewer lines, electric, gas and water lines that provide serviceto the adjacent commercial and industrial sites. The portion of the Former Morris Canal abutting Sites090 and 184 is paved and contains a 36-inch diameter sewer pipeline (force main) owned and operated bythe BMUA; the pipeline is constructed of steel with concrete casing support, with the top of the pipelinesituated just below the surface pavement. Honeywell has reached agreement with the BMU A regardingthe purchase of the property comprising Site 153, and anticipates completion of the property transactionin the next several months.

2.2 SITE HISTORY

The operating history for the properties comprising the Site was documented in the Remedial InvestigationReport (RJR) dated November 1999 (TetraTech, 1999). Site history for the Baldwin Steel and M.LHoldings Sites are summarized below.

Baldwin Steel (Site 90)The properties comprising the Baldwin Steel Site have been used for industrial purposes forapproximately 100 years. The parcel designated as Block 1286, Lot 6D was deeded to the MutualChemical Company in April of 1895. This property was transferred to AlliedSignal (formerly AlliedChemical and Dye Company) in August 1955, to Ryerson Steel in 1966, and then to Baldwin Steel in1970. During its industrial history, this parcel was used to support the production of sodium dichromate(Mutual Chemical), steel production (Ryerson Steel), or steel cutting and rolling (Ryerson and BaldwinSteel). During the period of AlliedSignal's ownership from 1955 to 1966, this parcel was a vacant lot.The adjacent lot, Block 1286, Lot 5, was transferred from John and Mary Winner to Ryerson Steel inAugust 1914, and then to Baldwin Steel in 1970. This parcel was used for either steel production,fabrication, or rolling and cutting of steel throughout its industrial history.

No detailed historical information regarding the placement of Chromium Ore Processing Residue(COPR) on this property is available. It is believed that chromite ore was stored on a portion of Lot 6Dby the Mutual Chemical Company during approximately 60 years of operation.

M.l. Holdings (Site 184)The M.I. Holdings Site was used by industrial or commercial enterprises for over 90 years. A portion ofthe property was deeded to the Chicago Railroad Equipment Company in 1899, and another portion wasleased to Kewanee Manufacturing through 1909. A portion of the property was subsequently deeded toRudolph Chillington (1912), Chillington Manufacturing Company (1914), and Mallinclcrodt ChemicalWorks (1939). Another portion of the property was deeded to the Mallinckrodt Chemical Works in 1918.

Prior to 1940, Mallinclcrodt produced inorganic chemicals such as salts or oxides of iron and mercmy.During the 1940s, Mallinckrodt participated in the Manhattan Project under contract with the U.S.Government for the testing of uranium trioxide. Mter World War II, the plant continued to producemercury compounds and other inorganic chemicals such as zinc acetate, potassium sulfate, potassiumchloride, ferrous sulfate, ferric chloride, and sodium nitrate. Production of mercury compounds endedaround 1974, when general facility improvements were made including demolition of the mercuryproduction equipment and various buildings. The majority of the open areas on the property were pavedat that time.

From thc 1940s to approximately 1980, Mallinckrodt also conducted packaging operations (both wet anddry operations) at the facility for a variety of both organic and inorganic chemicals. Some of the liquidpackaging operations included preparation of bottles of alcohols, acetone, xylenes, benzene and toluene.Organic liquids were received by railroad or truck in drums and carboys before packaging in bottles. Thebottled liquids were stored in various warehouses at the facility. Mineral acids and ethers were alsoreceived by railroad for packaging operations. In the late 1970s, most ofMallinckrodt's operationsdecreased to the production or packaging of the chemicals noted above as a result of the transfer ofmaterial handling and sub-division (packaging) operations to a new plant in Kentucky. In the early1980s, Mallinckrodt's production of chemicals was primarily limited to calcium and zinc stearatedispersions. All other production operations (packaging of organic and inorganic chemicals) ceased by1982. Zinc stearate dispersion production ceased in the late 1980s. More recent operations by M.I.Holdings were limited to the production of calcium stearate dispersions. As previously noted, a remedial

TIERRA-B-015018

action was conducted on behalf ofM.I. Holdings by Woodward-Clyde Associates during 1993. Theremedial action consisted of excavation of mercury/chromium-impacted soil, building demolition andasphalt paving as a cap. A deed notice and classification exception area (CEA) was also established forthe western portion of the site.

Former Morris Canal (Site 153)Historical information and maps indicate that the fonner Morris Canal was located along the area nowoccupied by Route 440 (formerly Route 9W) during the 1800s and early 1900s, and that the canal wasclosed during the 1920s and subsequently filled in. Historical maps indicate that a railroad line (LehighValley Railroad) was also located along the area of the former canal during the early to mid-1900s.Chromite ore production residue (COPR) was allegedly used as fill for a portion of the former canal.During 1990, the City of Bayonne excavated a section of the former Morris Canal, installed a sewagepipeline, and backfilled the excavation with clean fill. Pursuant to a "Release and Agreement" reachedbetween the City of Bayonne and Allied-Signal, Inc., the City of Bayonne was responsible for theexcavation and disposal of soils containing hazardous substances and/or wastes as part of the sewer lineinstallation project. The property was paved with asphalt following installation of the sewer line.

2.3 ENVIRONMENTAL SETTING

2.3.1 Regional and Site Geology

Information on regional and Site geology is presented below based on information from the RIR(TetraTech, 1999) and the ongoing regional groundwater investigation associated with Study Area 7(HydroQual, 2005; 2007). Relevant reference information and figures are included in Appendix A.

Regional GeologyJersey City is located within the upper portion of the drainage basin for Newark Bay, and lies within theglaciated section of the Piedmont Province. The bedrock in most of the region is comprised of LowerJurassic to Upper Triassic age sedimentary rock units known as the Newark Supergroup, and was formedfrom sediments deposited within a northeast-southwest trending structural basin known as the NewarkBasin. The sedimentary rocks of the Newark Supergroup in New Jersey are composed of reddish-brownarkosic sandstone, mudstone, siltstone, conglomerate, and dark gray argillite. These sedimentary rockunits have been intruded by igneous rock units (primarily diabase) in the form of sills and dikes, whichnow generally form ridges such as the Palisades and the Heights in Jersey City.

The Newark Supergroup has been divided into three formations on the basis of distinctive lithology: (1) alower unit identified as the Stockton Formation; (2) a middle unit identified as the Lockatong Fonnation;and (3) an upper unit identified as the Brunswick Group. Based on geologic mapping performed acrossnorthern New Jersey, including Study Area 5 (Drake, Jr., et aI., 1996), it is anticipated that SA-5 overliesa contact between the predominantly mudstone units of the Lockatong Formation and the north-northeasttrending diabase dike to the east. Regional mapping also indicates a north-northeast trending, southeastdipping normal fault lies approximately one-half mile east of the Site. Additional geologic information iscurrently being collected as part of the SA-7 investigation.

The beds of the Newark Supergroup generally strike to the northeast in the Hackensack River basin anddip at approximately 16 degrees to the west-northwest. A prominent set of vertical joints strike N 45° E,approximately parallel to the strike of the beds. A less prominent set of nearly vertical joints strike north75 degrees west, sub-parallel to the dip of the bedding (Anderson, 1968). Faults, where present, typicallystrike northeastward and are parallel to or intersect the strike of the beds at low angles. The bedrocksurface is irregular, shaped by pre-glacial and interglacial streams and further modified by glacial scour.

TIERRA-B-015019

The bedrock surface is overlain by glacial till/stratified lacustrine deposits, and alluvialliacustrinedeposits laid down by several glacial advances across the area, principally during the Wisconsin glacialperiod. The glacial till is generally described as an unsorted mix of sand, gravel, silt and clay in acontinuous layer overlying bedrock, as well as in discontinuous lenses within the stratified lacustrinedeposits. The lacustrine deposits generally consist of very fine sand, silt and clay with noticeablelayering and varves characteristic of alluvial deposition. The alluviaVlacustrine deposits are typicallycharacterized as a fine to medium sand with some silt that appear to coarsen to the east.

The various glacial deposits are typically overlain by Holocene age alluvium deposited within thefloodplains of present day streams. Meadow mat, consisting of decaying marsh deposits, is also found inmany low lyin g areas and much of the region has been artificially filled with material of varyingcomposition in an effort to raise the ground surface above the surrounding surface water features.

Site Geology

Fill MaterialThe majority of the ground surface at the Site is covered with asphalt pavement (parking lots, roads) orbuildings, which overlie a continuous layer of man-emplaced fill material. The fill ranges in thicknessfrom approximately 5 to 17 feet, with an average thickness of 10 to 12 feet, and generally consists of siltysand with miscellaneous construction debris such as gravel, brick, glass, wood, and concrete. Slug testresults for the fill zone indicate generally low permeability on the order of approximately 0.5 feet/day.

Meadow MatMeadow mat consists of a highly organic deposit of peat and fine-grained sediments that occurs in a thinlayer in the western portion of the Site. Meadow mat is generally not present beneath the majority of theSite further east from the fonner Moms Canal.

Lacustrine SandThe Lacustrine Sand has generally been described as a fine to medium sand with some silt that directlyunderlies the fill material and meadow mat (where present). Occasional discontinuous layers of brown-gray sand are present near the top of the unit as are fine-grained silt lenses throughout. This unitcorrelates to the S-2 Sand identified beneath SA-7. The thickness of this unit general1y increases fromeast to west and from north to south and is bifurcated beneath SA-7 by a red clay unit. Three (3) slugtests conducted in the Lacustrine Sand during the Rl suggest hydraulic conductivity values on the orderof 0.5 feet/day, whereas eleven slug tests constructed in wells screened within this stratum beneath SA-7suggest hydraulic conductivity values on the order of 5.0 feet/day.

Glacial Till Lacustrine DepositsThis unit consists of ice contact stratified drift including fine sands with inter-layered seams of silt andclay. Occasional lenses of coarse sand and gravel have also been observed in this unit. The limited dataavailable on these deposits suggest hydraulic conductivities on the order of 0.1 ft/day.

BedrockThe bedrock consists of the Triassic age Lockatong formation of the Newark Supergroup and may beunderlain in the eastern most area by Diabase. The bedding planes dip generally to the northwest atapproximately 15 degrees while the bedrock surface generally slopes to the southwest. The bedrock isapproximately 110 ft below ground surface in the vicinity of the SA-5 (HydroQual, February, 2007).

2.3.2 Regional and Site Hydrogeology

Regional HydrogeologyThe Site is located in a broad area of low relief near Newark Bay, with expected low groundwatergradients. Close to the bay, shallow groundwater is influenced by tidal fluctuations, with low-lying andmarshy areas being only slightly above high tide. Regionally, groundwater flow is generally toward themajor water bodies in the area, including the Hackensack River, Passaic River, and Newark Bay. Thesemajor water bodies serve as regional groundwater discharge points and hydrogeologic boundaries. Thesize and influence of these water bodies is such that groundwater will not migrate across them, but willdischarge to the rivers and the bay.

The groundwater underlying the Hudson County Chromium Sites can be characterized as a multi-aquifersystem. In general, there are two water-bearing zones/systems underlying the study area: (I) a surficialwater-bearing zone within unconsolidated materials consisting of man-deposited fill, glacial drift(composed of clay, silt, sand, gravel, and boulders), fluvial fine- to medium-grained sand, and (2) theunderlying water-bearing zone within fractured bedrock.

Groundwater in the shallow, unconfined to semi-confined water-bearing zone is recharged through directinfiltration of precipitation. Groundwater movement within this zone is through pore spaces betweensediment grains. Depths to groundwater vary from less than one foot to 10 feet bgs or more. Thedirection of shallow groundwater flow is toward local surface waters that serve as groundwater dischargepoints, including small, unnamed drainages, the nearby rivers, and Newark Bay. Close to the rivers andthe bay, shallow groundwater is tidally influenced.

Site HydrogeologyGroundwater beneath the Site occurs within the fill material and underlying lacustrine sand depositsunder unconfined conditions, and within the underlying bedrock under confined or semi-confinedconditions. A layer of meadow mat in the western portion of the Site, separates the fill material from theunderlying natural formations. Where the meadow mat is absent, the two units may be in contact.

Existing data shows that the upper (fill) and deeper (natural) groundwater bearing zones are distinct,where separated by the meadow mat. Groundwater flow pattern and direction are different in the twounits. Contaminant distribution profiles in the two units are also distinct. Chromium is the onlycontaminant detected in the deeper zone, while a suite of contaminants has been detected in the shallowzone. The SA-7 investigation has shown that, where the meadow mat is present, chromium has notmigrated vertically from the shallow to the deeper zones. Based on these data, it has been concluded thatcontamination in the shallow zone above the meadow mat is associated with chromium-impacted fill,while contamination in the deeper units is related to historical discharges at the former Mutual Chemicalfacility located south of the Site.

Groundwater flow in the area of the Site has been mapped as part of the comprehensive SA-7investigation, which has identified four hydrostratigraphic zones as follows:

Shallow Zone - above the meadow mat and generally in fill materialIntermediate Zone - just below the meadow mat (generally not present beneath SA-5)Deep Zone - within the lacustrine deposits just above the glacial till/ice contact depositsUpper Bedrock Zone - Just below the top of bedrock

10

TIERRA-B-015021

Regional groundwater contour maps for the Shallow and Deep Zones are presented on figures inAppendix A. The groundwater contour maps indicate that groundwater flow in the fill material (ShallowZone) is generally to the west or northwest and is strongly influenced by near surface features such as thestonn sewer along Route 440. Groundwater flow in the lacustrine deposits (Deep Zone) is similarly tothe west-northwest, with little or no influence from near surface features, thus groundwater flowcontinues west and northwest to the Hackensack River. Groundwater flow within the Upper BedrockZone beneath SA-7 is to the northwest, and similar conditions are expected beneath the Site.

As previously indicated, slug test data for the Shallow Zone (Fill) indicate a relatively low permeabilityfor the fill material of approximately 0.5 feet/day, with an estimated flow velocity of 3 feet/year based onaverage gradient of 0.005 and porosity of 30% (TetraTech, 1999). Slug test data for the Deep Zone(Lacustrine Sand) indicate hydraulic conductivity values on the order of 5.0 feet/day, with an estimatedflow velocity on the order of 18 feet/year based on an average hydraulic gradient of 0.003 and porosity of30%. Limited data available for the glacial till/ice contact deposits suggest hydraulic conductivities onthe order of 0.1 feet/day.

Based on information from the RIR, there are no public water supply wells located in Hudson County. Aprevious file search was conducted during 1999 at the NJDEP Department of Water Allocation Divisionoffice in Trenton, NJ. Coordinates of the study area were supplied, and microfilm records of wellswithin one mile of the study area were obtained. A review of the information indicates that there are noindustrial or public water supply wells down-gradient from the Site.

2.3.3 Site Topography and Surface Water

The ground surface at the Site is relatively flat, bordered by Route 440 to the west and West Side Avenueto the east. Ground surface elevations range from approximately 8 to 20 feet above mean sea level(MSL), with the highest elevations on the eastern portion of Site 090 (Baldwin Steel). Historically,ground surface elevations were approximately 5 to 10 feet lower prior to placement of fill across the area.The ground surface at Site 090 (Baldwin Steel) is approximately 5 to 10 feet higher than the groundsurface at the Site 184 (M.I. Holdings), indicating a greater amount of fill on Site 090 (Baldwin Steel).Surface water runoff in the area of the Site is controlled by surface pavement and storm water catchbasins located within the Site property and along surrounding streets.

The Fonner Morris Canal runs north-south along the western boundary of the Site along Route 440. Theportion ofthe canal through Jersey City opened in 1836 and was filled with salt water, and this section ofthe canal was equipped with tide locks at both ends that prevented the water from flowing out at low tide(http://www.jerseycityonline.comlmorris_cana1.htm). The canal was closed and drained in 1924. Thecanal was subsequently filled in and no visual evidence of the former canal exists. The majority of theformer canal area is now covered with pavement, and the portion of the former canal next to the Sitecontains a sewer line.

No surface waters are present at or adjacent to the Site. The principal water bodies in the vicinity of thesubject Site include the Hackensack River, Passaic River, and Newark Bay. The nearest surface waterbody is the Newark Bay, located approximately 4,000 feet to the west. The Site is located within theHackensack River basin, which extends northward from Newark Bay into southeastern New York State.The Hackensack River is used for water supply in the upper reaches of the basin; however, in the vicinityof the Site, the river is classified as SE-3 (saline estuarine waters) with the following designated uses:

1. Secondary contact recreation;2. Maintenance and migration of fish populations;

II

TIERRA-B-015022

3. Migration of diadromous fish;4. Maintenance of wildlife; andS. Any other reasonable uses

Several municipalities draw water from the river during the summer months, resulting in very little netflow in the lower reaches of the river during the time periods of water diversion from the river. Thisresults in poor flushing of the lower reaches (tidal portion) of the river during these time periods.

The Hackensack River is tidally influenced along the reach adjacent to Jersey City. According toNational Oceanic and Atmospheric Administration (NOAA) records, the mean tide level of theHackensack River in the area of Jersey City is approximately 2.84 feet above MSL and the mean tiderange is approximately 5 feet. Water quality in the Hackensack River is affected by industrial discharges(over 100 permitted discharges into the river) and by the tides. Low dissolved oxygen levels are commonin the river during the summer, and total dissolved solids levels are slightly to moderately saline.

2.4 CURRENT AND FUTURE LAND USE

Currently, Site 090 (Baldwin Steel) is inactive and consists of a vacant fenced lot with the majority of theground surface covered with building structures and pavement. Site 184 (M.I. Holdings) consists of afenced paved [at with several buildings and small landscaped areas. As previously indicated, theseproperties are proposed to be redeveloped by NJCU into a mixed use facility consisting of student housing,retail, and other residential and educational functions. Preliminary Site plans for the NJCU developmentproject are included as Figure 2. Demolition activities (including the former Baldwin Steel building) wereperformed during 2006. The current estimated Site redevelopment schedule includes constructionbeginning during the latter part of2008.

2.5 PREVIOUS INVESTIGATIONS/REMEDIALACTIONS

Previous investigations and remedial actions conducted at Site 090 (Baldwin Steel) and Site 184 (M.l.Holdings) prior to the Rl are summarized in this section, along with information on Site 153 (FonnerMorris Canal) located along the western boundary of Sites 090 and 184. R1 results based on the findingsfrom the RlR and RIR Addendum are presented in Section 3.0.

Baldwin Steel (Site 90)Samp] ing of surface and subsurface fill material was conducted in March 1989 by Langan EnvironmentalServices, Inc. (Langan, 1989). In addition to total chromium analysis, qualitative colorimetric analysisfor hexavalent chromium was conducted. A total of nineteen (19) samples were collected over a gridsystem around the perimeter of the Baldwin Steel building. Total chromium concentrations ranged from125 mglkg to 15,810 mg/kg. Colorimetric responses indicating the potential presence of hexavalentchromium were noted in all but two of the samples collected. NJDEP conducted a building inspection onJanuary 12, 1994. As a result of this inspection, the NJDEP concluded that there was no visual evidenceof chromate contamination at the facility.

A contractor for Allied Signal, Inc. completed an Interim Remedial Measure (asphalt cap) at the BaldwinSteel Site in 1990. Capping of areas of exposed soil was completed during the Interim RemedialMeasure. This remedial measure was completed to prevent direct contact exposures, control potentialfugitive dust emissions, reduce percolation of precipitation, and prevent overland runoff of chromiumcontaining materials. A contractor for Allied Signal, Inc. also upgraded the asphalt cap by placement androlling of additional asphalt along the southern fence line in October 1994.

TIERRA-B-015023

M.1. Holdings (Site 184)SamplIng and analysis of soil and groundwater were conducted by A WD Technologies and Woodward-Clyde Consultants. AWD Technologies installed six (6) monitoring wells at the Site in 1987 (threeshallow and deep clusters) and sampled these wells on three occasions in 1987 and once in 1988. Inaddition, three (3) soil samples were collected during the installation of these wells. In 1993, Woodward-Clyde collected surface and subsurface soil samples at 17 locations in the southwestern comer of theproperty and subsequently collected eight (8) post-excavation sidewall samples. Woodward-Clyde alsocompleted one round of monitoring well sampling and analysis in 1993. Total chromium concentrationswere detected in soil samples up to 36,000 mglkg. Total chromium concentrations were detected inunfiltered and filtered groundwater samples up to 2.24 mg/I and 2.0 mg/I, respectively.

A remedial action was conducted at the M.l. Holdings Site by Woodward-Clyde in 1993. The remedialaction was conducted to remediate (remove) soil containing mercury. Based on a summary reportprepared by Woodward-Clyde, approximately 900 cubic yards of sail/fill were excavated from threeareas located in the southwestern comer of the property. Excavation depths ranged from two tothree feet. A narrow strip of land along the western boundary of the Site was not remediated. Thisportion of the Site was investigated during the RI for soils.

TetraTech, Inc. on behalf of New Jersey City University (NJCU) performed additional RI activities onthe Site during 2004-2006 to address non-chromium contaminants under a Memorandum of Agreementwith the NJDEP. The additional RI activities included geophysical survey, test pit investigation, soil andgroundwater sampling, and baseline ecological evaluation (BEE). The results of these activities weredocumented in a Remedial Investigation ReportlRemedial Action Work Plan (RIRIRA WP) (TetraTech,February 2006), which is currently under review by the NJDEP. The recommendations proposed in theRIRJRA WP include pre-design investigations, investigation of catch basins and sewer lines, investigationof sub-slab areas following removal of building slabs, and further delineation of chlorinated VOCs (e.g.,carbon tetrachloride) in groundwater. The recommended remedy includes extension of the existing capand deed notice area to cover the entire Site, and maintaining the existing CEA for residual groundwatercontamination. A figure illustrating the proposed remedial actions is included in Appendix A-5.

Former Morris Canal (Site 153)The property comprising the Former Morris Canal Site consists ofa narrow strip ofland along theshoulder of Route 440 North. The portion of the Former Morris Canal Site located adjacent to Sites 090(Baldwin Steel) and 184 (MI Holdings) is approximately 700 feet long and 40 feet wide. In 1990, theCity of Bayonne excavated a section of the former Morris Canal, installed a sewage pipeline, andbackfilled the excavation with clean fill. Pursuant to a "Release and Agreement" reached between theCity of Bayonne and Allied-Signal, Inc., the City of Bayonne was responsible for excavation and disposalof soils containing hazardous substances and/or wastes as part of the sewer line installation project. Theproperty was paved with asphalt following installation of the sewer line. Previous investigations on theportion of the Former Morris Canal Site adjacent to Sites 0901184 were conducted during 1997-1999 anddocumented in the RIR dated November 1999. The Rl results are discussed in Section 3.

3.2.1 Soil Borings/Soil Sampling

A total of nine (9) soil borings were advanced using hollow-stem auger (HSA) drilling methods and/ordirect-push sampling equipment. The borings included seven (7) locations in the western portion of Site90 (Baldwin Steel) and two (2) locations on Site 184 (M.!. Holdings), designated as follows:

090-$B-001: within area of chromium-impacted soils beneath existing building090-SB-002: within area of chromium-impacted soils in western portion of property090-SB-003: refine horizontal delineation in south-central portion of property090-SB-004: refine horizontal delineation in south-central portion of property090-SB-005: refine horizontal delineation in south-central portion of property090-MW -010: within area of chromium-impacted soils in southwest portion of property090-MW -011: upgradient of existing monitoring well MW -090-EO 1l84-MW -00 l: upgradient of chromium-impacted fill soils184-MW -002: within area of chromium-impacted soils in northwestern portion of property

Soil borings were advanced to a maximum depth of approximately 20 feet bgs, and soil samples werecollected using split-spoon samplers. Soil samples were visually inspected for the presence of COPR(e.g., yellow-green or colored staining or nodules), and field screened for the presence of organic vaporsusing a photo-ionization detector (PID). Soil boring logs are included in Appendix C.

Soil samples were collected from three (3) locations (090-S8-003, 004,005) and submitted for laboratoryanalysis for total chromium and hexavalent chromium to provide additional data for delineation beneaththe existing building. Selected soil samples were also submitted for laboratory analysis for SyntheticPrecipitation Leaching Procedure (SPLP), total and hexavalent chromium. Selected samples were alsocollected and submitted for grain size analysis. Sample depth intervals for SPLP analysis corresponded

Two (2) rounds of groundwater sampling were completed during 2005 including one round on April 28,2005 and a second round on May 31, 2005. Three (3) rounds of groundwater sampling were completedduring 2006 as follows: May 10,2006, August to, 2006, and December 13, 2006. Groundwatermonitoring well sampling procedures included low flow purge/sample methods. Field sampling includedwater level measurements and the collection of field parameters including pH, temperature, conductivity,dissolved oxygen (DO), and reduction-oxidation potential (Redox). Groundwater sampling field datasheets and groundwater contour map reporting forms are included in Appendix E.

HydroPunch groundwater samples were also collected during soil boring activities from two soil borings(SB-003 and SB-005) and analyzed for total and hexavalent chromium (unfiltered and filtered) to provideadditional data on shallow groundwater for the southern portion of the Site beneath the existing building.Groundwater grab sample 090-PZ-OOl was collected from 090-SB-003 borehole, and sample 090-PZ-002was collected from 090-SB-005 borehole. The screened interval at both locations was from 3 to 13 ft bgs.

Groundwater samples were submitted for laboratory analysis for total and hexavalent chromium(unfiltered and filtered). The first round of sampling also included the following additional watcr qualityparameters to provide additional data for evaluation of natural attenuation and groundwater treatmentoptions: pH, alkalinity, calcium, iron, magnesium, ferrous iron, sulfate, and total organic carbon (TOC).Groundwater sampling results for samples collected during 2005 and 2006 are summarized on Tables 3and 4, respectively.

Laboratory analytical parameters and methods fOT groundwater samples included:

Total Chromium using USEPA Method 6010BHexavalent Chromium USEPA Method 7196AOther Water Quality Parameters: pH (Method 150.1); Alkalinity (Method 310.1); Calcium, Iron andMagnesium (Method 60 lOB); Ferrous Iron (Method 3500-Fe), Sulfate (Method 375.4), Sulfide (Method376.1), Total Organic Carbon (Method 415.1)

3.3 SOIL INVESTIGATION RESULTS

The Rl soil investigation activities were conducted in several phases, with results summarized below.

3.3.1 Remedial Investigation Report (1999)

The RI soil investigation was conducted in several phases during 1997 to 1999 and reported in the DraftRIR (Tetra Tech NUS, Nov, 1999). A total of 47 soil borings (up to 8 feet bgs) were completed on thesubject Sites, including 15 borings at Baldwin Steel, 12 borings at M.I. Holdings, and 20 borings within theFormer Moms Canal. Samples were collected from selected depth intervals for submittal for laboratoryanalysis for total and hexavalent chromium. Approximately ten percent of the soil samples were alsoanalyzed for Target Compound List (TCL) volatile organic compounds (VOCs), semi volatile organiccompounds (SVOCs), and pesticide/polychlorinated biphenyls (PCBs); TAL metals; and total petroleumhydrocarbons (TPH).

Baldwin Steel (Site 090)

TIERRA-B-015028

the sec. PAHs and metals were also detected at concentrations below the sec, with the exception ofcopper (Sample 184-SB-A02-0406: 659 mg/kg) detected slightly above the SCC of 600 mglkg.

Former Morris Canal (Site 153)

A total of 26 borings were installed to characterize the former Morris Canal (Site 153), including five (5)borings (15 3-SB-AO 1 through ADS) within the portion of Site 153 next to Baldwin Steel (Site 090) andM.l. Holdings (Site 184).

Surface Soils: Chromium (total) was detected in all five surface soil samples at concentrations rangingfrom 59.3 mglkg to 11,200 mglkg (153-SB-05).

Surface soil samples were not analyzed for any other parameters.

Subsurface Soil: Chromium (total) was detected in all of the subsurface soil samples at concentrationsranging from 9.8 mglkg to 39,800 mg/kg. Hexavalent chromium was also detected in all of thesubsurface soil samples at concentrations ranging from 2.5 mg/kg to 9,150 mg/kg. The maximumconcentrations of both total and hexavalent chromium were detected in sample 153-SB-A05, collectedfrom a depth interval of 6-8 ft bgs near the southwest corner of Site 090.

Benzene was detected in sample 153-SB-A03 (1.3 mg/kg; 8-10 ft bgs) slightly above the NJDEP Impactto Groundwater Soil Cleanup Criteria of 1 mglkg near the western boundary of Sites 090 and 184.

3.3.2 Remedial Investigation Report Addendum (October 2004)

The RIR Addendum (Tetra Tech NUS, Oct. 2004) presents results of additional soil borings andsampling conducted during 2003 on the properties subject to redevelopment by NJCU, including 34borings at Site 090 (Baldwin Steel) and 12 borings at Site 184 (M.L Holdings). Approximately 440samples were analyzed for total and hexavalent chromium. The report also includes sampling results forthe portion of the Former Morris Canal adjacent to the Baldwin Steel and M.I. Holdings Sites.

Total chromium concentration ranged from 1.9 to 69,600 mg/kg, with the highest concentration detectedat090-SB-20 (8-10 ft bgs) in the southwestern portion of Site 090 (Baldwin Steel). Hexavalentchromium concentration ranged from less than 2 mglkg to 28,400 mg/kg in sample 090-88-114, whichwas collected at a depth of 6 to 8 feet bgs in the southwestern portion of Site 090 (Baldwin Steel).

Three (3) additional borings (184-SB-13, 184-SB-14, and 090-SB-37) were completed by Tetratech inFebruary 2005 to provide additional data in the eastern portion of the Site. A total of30 soil sampleswere collected and analyzed for total and hexavalent chromium from various depth intevals, and resultsindicated that hexavalent chromium was detected above 20 mg/kg in one sample (090-SB-13; 88.4 mg/kgat 0-2 ft bgs). All other samples contained less than 20 mg/kg of hexavalent chromium.

The RI soil data indicate that the horizontal and vertical extent of hexavalent chromium above theNJDEP soil cleanup criteria of 20 mg/kg was delineated (Figure 3). The portion of the proposedredevelopment area impacted by hexavalent chromium concentrations is along the western andsouthwestern boundaries (estimated at approximately 4.5 acres). The impacted area is bounded by theBaldwin Steel (Site 090) boundary to the south (adjacent Site 117 has already been capped byHoneywell), the Morris Canal Site to the west (where RI efforts are ongoing), and clean borings (noexceedances of 20 mglkg) to the north and east within the Baldwin Steel and M.L Holdings property

18

TIERRA-B-015029

boundaries. Hexavalent chromium concentrations slightly above 20 mglkg were detected in shallow soilsbeneath existing pavement at a few isolated locations outside the main chromium-impacted fill area.

Hexavalent chromium results exceeding the NJDEP soil cleanup criteria are indicated on Figure 3. TheRIR and RIR Addendum text and tables with soil sample results for total and hexavalent chromium areincluded in Appendix A for reference.

3.3.3 RIWP Addendum for Shallow Groundwater (April/May 2005)

Soil samples were collected from three (3) locations (090-SB-003, 090-SB-004, 090-SB-005) to provideadditional data for horizontal delineation in the southern portion of Site 090 beneath the existing building(as indicated on Table 1 and Figure 3). Total chromium concentrations ranged from 4.1 mg/kg to 555mglkg, with the maximum concentration of total chromium detected in sample 090-SB-003 (12-14 feetbgs). Total chromium did not exceed the NIDEP sce of 120,000 mglkg for trivalent chromium.Hexavalent chromium concentrations were less than 20 mglkg, with the exception of one sample: 090-SB-003 (91.3 mglkg at 12-14 ft bgs). Grain size analysis was performed on samples obtained fromlocations 090-SB-00l, 090-SB-002, 090-8B-003, 090-MW-OI0, 090-MW-Ol1 and 184-MW-002. Amajority ofthe samples were described as a fine to medium sand (Table IB).

3.3.4 Additional Soil Delineation (November 2006)

Additional soil sampling was performed during November 2006 to provide further soil delineation underproposed building footprints (Buildings 5 and 7) in the southwest portion of the Site, and to evaluate soilpH data with respect to sources of chromium impacts (i.e. COPR fill versus dichromate sources). Soilsamples were collected at 2-foot intervals from 14 sampling locations (090-SB-006 through 090-SB-O 19)to the top of the peat stratum (maximum 16 feet bgs). Results are summarized on Table 2 and Figure 3.Analytical data packages and electronic data deliverables are contained in Appendices F and M,respectively. Boring logs are contained in Appendix C.

Analytical results were used to confirm chromium-impacted soils beneath proposed Buildings 5 and 7.Field observations of eOPR-impacted fill and elevated hexavalent chromium results (> 1,000 mglkg)were noted at seven locations (090-8B-007, 090-SB-008, 090-SB-OI5 through 090-SB-019). Hexavalentchromium concentrations were slightly above 20 mg/kg at four locations (090-8B-009, 090-SB-OI0, 090-88-012, 090-SB-0 14). The remaining samples did not contain hexavalent concentrations in excess of 20mg/kg (090-SB-006, 090-SB-Oll, 090-88-013).

Soil samples were also analyzed for pH to evaluate the source of hexavalent chromium. High pH values(>11) were detected in samples with hexavalent chromium levels above 1,000 mglkg and fieldobservations ofCOPR-impacted fill. Samples containing low levels of hexavalent chromium above 20mglkg showed relatively neutral pH results.

3.4 GROUNDWATER INVESTIGATION RESULTS

Groundwater investigations at the Site were conducted in several phases during the previous RI for SA-S,the supplemental RI activities conducted during 2005-2006, and as part of the regional groundwaterinvestigation under the oversight of a court-appointed Special Master for Study Area 7.

3.4.1 Remedial Investigation Results (November 1999)

Previous groundwater investigations included sampling of monitoring wells installed within SA-S as partof the RI, the SA-7 investigation, and other investigations completed on behalf of the property owner(NJCU). The RI activities for SA-5 included installation of 16 monitoring wells, including two (2) wellsat Baldwin Steel (Site 090) and three (3) wells at M.l. Holdings (Site 184). Groundwater investigationresults are sununarized in this section, with reference infonnation provided in Appendix A. A summaryoverview of previous groundwater investigation results by cae is provided below:

VOCs/SVOCsFive (5) monitoring wells were sampled for VOCs and SVOCs as part of an investigation on Site 184(MI Holdings) during September 1992 and March 1993. The following VOCs were detected above theGWQS in MW-3B: benzene (88-230 ug/L), xylene (200-220 ugIL), trichloroethylene (640-5,200 ug/L),1,2-dichloroethenes (total) (330-560 ug/L), and vinyl chloride (13-24 ug/L). The lower concentrationswere detected during the March 1993 sampling round, indicating declining concentrations. No SVOCswere detected above the GWQS. MW-3B, formerly located near the western boundary ofM.!. Holdings(Site 184), was screened from approximately 35 ft to 45 ft bgs, at the base of the Lacustrine Sand.

InorganicsThe majority of groundwater sampling completed within SA-S has been for inorganics. Samplingcompleted as part ofthe SA-5 and SA-7 regional groundwater investigations primarily focused onchromium and major cation/anions with some additional analyses for several anions/cations andmiscellaneous parameters. Work completed on the Site 184 (M.I. Holdings) focused on mercury but alsoincluded chromium and other Priority Pollutant List metals.

Chromium (total and hexavalent) was the most frequently detected metal with reported concentrationsabove the GWQS in both filtered and unfiltered samples. Other metals reported above the GWQS infiltered samples collected from Site 184 (M! Holdings) included cadmium (well MW-2B), mercury (wellMW-2A) and thallium (well MW-3B). Arsenic, lead, mercury, and thallium were also reported above theGWQS in groundwater samples collected from HydroPunch borings on Site 90 (Baldwin Steel).Additionally, the following inorganics were occasionally detected in groundwater above the GWQSduring the RI: aluminum, iron, sodium, ammonia, sulfate, chloride and total dissolved solids (IDS).Groundwater samples collected using low-flow sampling techniques typically have lower metalsconcentrations than either HydroPunch samples or samples collected using conventional samplingtechniques, which were likely used during the 1992 and 1993 sampling rounds.

Groundwater data collected during previous investigations associated with SA-5 indicate thatgroundwater impacts at Site 090 (Baldwin Steel) and Site 184 (M.l. Holdings) include total andhexavalent chromium above the GWQS. Chromium concentrations above the GWQS are present withinthe Shallow Zone (contained within the fill material) beneath most of Site 117 (Ryerson SteelfHomeDepot) and Site 153 (Morris Canal) adjacent to Route 440. As previously indicated, a thin layer ofmeadow mat is present in the western portion of SA-5, and a downward hydraulic gradient was identified

20

TIERRA-B-015031

between the fill material and the underlying lacustrine deposits. Where the meadow mat is not present,the shallow and deep zones are in hydraulic communication.

3.4.2 Report on Groundwater for Study Area 5 (October 2004)

HydroQual, Inc. prepared a draft report during October 2004 focusing on groundwater conditions at SA-5to support the development of a RASRJRA WP for Baldwin Steel (Site 090) and M.l. Holdings (Site 184).The report indicated that groundwater flow direction in the Shallow Zone at SA-S is generally toward thewest and north, and is influenced by near surface features including storm sewers along Route 440.

Hexavalent chromium concentrations detected in the shallow groundwater zone were generally below theGWQS (70 ug/L) in the majority of monitoring wells at Sites 90 and 184 within SA-5. Groundwatersample results for monitoring well 090-MW-EO 1 (located in the western portion of the Site near Route440) indicated total and filtered hexavalent chromium concentrations of770 ugIL and 583 ug/L,respectively. The report also contains results of groundwater grab (HydroPunch) samples collected byothers, indicating elevated chromium concentrations in the southwest portion of the property.

Vertical aquifer screening sample results obtained during installation of deep monitoring wells (090-MW-090, 90-MW-7BR) located in the southwestern portion of the Site indicate that hexavalentchromium was detected in 090-MW-090 above the GWQS (70 ug/L) near the bottom of the fill unit (12-14 feet bgs) and at various depths greater than 25 feet bgs, with the highest concentrations detected atdepths below 60 feet bgs. There were no detections in the interval between the bottom of the fill and thedeeper natural deposits. Vertical screening results for 090-MW -7BR indicate that hexavalent chromiumconcentrations above the GWQS were limited to samples collected from depths below 25 feet bgs. Thevertical aquifer screening results indicate that the chromium levels detected in the deep groundwater zoneare several orders of magnitude greater than the Shallow Zone. The groundwater data indicate that thehighest hexavalent chromium concentrations in the shallow groundwater zone have been detected at SA-7 (Sites 87 and 115) on the opposite (west) side of Route 440, and other nearby Sites associated with SA-5 (Sites 117 and 153) south of the subject Site.

3.4.3 Deep Overburden Groundwater Report for Study Area 7 (February 2007)

As part of the Regional Groundwater study for SA-7, HydroQual, Inc. on behalf of Honeywell prepared aFinal Groundwater Investigation Report dated February 2, 2007 to describe the hydrogeology of the deepoverburden deposits in the vicinity of Study Areas 5,6, and 7, and to characterize the deep overburdengroundwater chromium plume (HydroQual, 2007). This study included both the landward portion of theplume and the portion that extends beneath the Hackensack River. The term "deep overburden" refers tothe deposits between the meadow mat and the bedrock surface. Groundwater occurs within the fillmaterial above the meadow mat under unconfined conditions, and within the lacustrine sand and bedrockunder semi-confined and confined conditions, respectively. The report indicates that groundwater flowin the intermediate zone below the meadow mat is toward the Hackensack River. Groundwater flow inthe deep zone is to the west-northwest beneath SA-5. but then turns to the north-northwest beneath SA-7and SA-6 North. A coarse-grained sand deposit (beneath the eastern portion of SA-7) and the lowpermeability red clay (beneath the western portion of SA- 7) control groundwater flow in the deep zone.

Two independent chromium plumes have been identified; one in the fill and shallow overburden abovethe meadow mat, and one in the deep overburden. Chromium in the shallow overburden plume is a resultof groundwater in direct contact with COPR, and COPR-impacted soil, and is unrelated to the deepplume, which has its origin at the former Mutual Chemical Company production facility east of Route

21

TIERRA-B-015032

440 (Site 117; current location of the Home Depot facility). The report indicates that the source of thedeep plume is from the historic vertical migration of chromium through the lacustrine sands into the deepoverburden. The deep plume then travels through the deep, highly penneahle, coarse-grained sand layerwhere it travels horizontally to the north-northwest where it moves back up through the lacustrine sandsultimately discharging to the Hackensack River.

In contrast to the COPR-related sources of the shallow plume, the deep overburden plume was likelycaused by historic releases of chromate solutions from the various processes at the fanner MutualChemical Company production plant. Based on the historical information provided in the FinalGroundwater Investigation Report, the most likely location of process-related discharges is in the vicinityof Building F, in the northwest comer of the fonner plant, where the "wet" operations took place. Thevertical profile of hexavalent chromium concentrations in pore water adjacent to the wet operations areasupports the conceptual model of process-related discharges. Pore water quality data collected fromborings 090-MW-07, I 17-MW-I4, and 090-MW-07BR located within close proximity to the wetoperations indicate that hexavalent chromium is present throughout the entire vertical column from theShallow Zone to the top of bedrock. Concentrations range from a low of 1.5 mgIL to a high of 6,920mg/L. This was the only location within the project area in which such a vertical continuum wasidentified. The highest concentrations noted in these borings are at a depth of approximately 65 feet andin contact with the 5-3 Sand. The fact that the Shallow and Intermediate Zones in this source areacontinue to exhibit hexavalent chromium in concentrations in excess of 10 ppm, indicates that residuefrom past housekeeping practices may still be present in the subsurface. Although a relatively thin layerofCOPR-Iike material was identified in boring 117-MW-I4, it is unlikely that this small volume could besolely responsible for the persistence of these elevated concentrations decades after plant operations haveceased. It is more likely that some form of solid-phase residual of the historical sodium chromatedischarges is present within the fill and/or underlying lacustrine deposits.

Hexavalent chromium was detected in the deep overburden at concentrations greater than 1,000 mglL inthree wells: 090-MW-09 had 2,460 mg/L in the unfiltered sample collected in April 2004; 117-MW-14had 6,920 mg/L in the unfiltered sample collected in December 2006; and 115-MW-19 had 2,250 mgILin filtered sample collected in September 2004. These wells are located within the Site property,adjacent to the Site property, and approximately 400 feet west of the Site, respectively. Vertical aquifersampling results indicate that the chromium levels detected in the deep groundwater zone are severalorders of magnitude greater than the Shallow Zone. Vertical aquifer sampling results and relevantfigures from the reglOnal investigation illustrating the regional extent of chromium impacts and verticalgradients are included in Appendix A.

Hexavalent chromium was a(so detected beneath the riverbed sediments at concentrations ranging from0.732 mg/L to 218 mg/L. The report indicates that the plume is believed to have attained a largelysteady-state position beneath the river with ongoing discharge upward through the relatively thinsediments in a topographic depression area beneath the river, with little or no further lateral migration ofthe plume. Hexavalent chromium was not detected above the detection limit of 5 ugll in any of the 26pore water sample locations beneath the river. (HydroQual, Inc., 2007).

HydroQual conducted an evaluation of deep overburden groundwater remedial alternatives to addresschromium contamination, as presented in the Deep Overburden Groundwater Remedial Alternatives(DORAA) Report (HydroQual, Inc., 2006). The evaluation included a recommendation that AlternativeNo.3, consisting of a groundwater pump/treat system that captures the entire deep overburdengroundwater plume, be implemented. Alternative No.3 includes pumping of an extraction well, located

3.4.4 RIWP Addendum for Shallow Groundwater (April/May 2005)

Groundwater sample results for two rounds of sampling performed during 2005 (April and May) areindicated on Table 3 and Figure 5. Monitoring wells sampled include 090-MW-EOl, MW-090-010,090-MW-Oll, l84-MW-OOl, I84-MW-002 and 090-MW-8A. Groundwater field parametermeasurements are indicated on the groundwater sampling field data sheets in Appendix E. Groundwaterelevation data are presented in Table 5. Groundwater contours are included as Figures 4A and 4B.

Total cltromium was detected in the following monitoring wens above the GWQS (70 ugIL) with maximumconcentrations shown in parenthesis: 090-MW-EOI (117 ugIL); 090-MW-OlO (5,280 ug/L); 184-MW-D02(245 ug/L) and 090-MW-8A (514 ugIL). Elevated total cltromium concentrations were also detected ingroundwater grab samples 090-PZ-00I (7,220 ugIL) and 090-PZ-002 (2,640 ugIL). Groundwater grabsample 090-PZ~001 was collected from 090-SB-003 borehole, and sample 090-PZ-002 was collected from090-SB-005 borehole. The screened interval at both locations was from 3 to 13 ft bgs. These results arelikely biased high due to the groundwater grab sampling method. Hexavalent chromium was detectedabove the GWQS in two wells as follows: 090-MW-OIO (5,220 ug/L) and 90-MW-8A (497 ugIL). Both ofthese wells are located within the area of chromium-impacted soils in the southwest portion of the Site.Field measurements indicate that elevated pH levels were detected at 090-MW-01O (pH > 12), whereasneutral pH conditions were detected at other wells including 090-MW -8A (pH of 6.44). Groundwater fielddata indicate relatively neutral pH values (ranging between pH 6 to 9), with the exception of 090-MW-O 10in the southwest portion of the Site.

Groundwater sampling included other water quality parameters (selected metals, alkalinity, ferrous iron,sulfate, TOC) and field measurements (DO, oxidation-reduction potential [ORP]) to provide additionaldata for evaluation of natural attenuation and potential groundwater treatment options. Alkalinity valuesranged from 46 mg/I to 789 mgll, with the highest alkalinity values detected in 184-MW -002 and 090-MW-OIO. Ferrous iron, sulfate, and TOe values ranged from 0.15 to 0.24 mg/I; 9.8 to 45.5 mg/I; and 2.5to 20 mg/I, respectively. DO results ranging between I to 10 mgll were detected in the majority ofmonitoring wells, with the exception of090-MW-0IO and 090-MW-Ol I which had DO values below Imglkg or non-detect. ORP results indicated negative values in the majority of wells, with the lowestvalues detected in 090-MW-OIO. Data for 090-MW-OIO include a lack of DO along with negative ORPvalues, indicating anaerobic reducing conditions where the highest chromium concentrations weredetected in the southwest portion of the Site. The results indicate subsurface conditions favorablefor chromium reduction (Cr -6 to Cr~3) in groundwater beneath the Site.

3.4.5 Additional Shallow Groundwater Sampling (May/August/December 2006)

Groundwater sample results for sampling performed during May, August and December 2006 areindicated on Table 4 and Figure 5, Monitoring wells sampled include 090-MW-OlO, 090-MW-ll, 090-MW-8A, 090-MW-E01, l84-MW-OOI, 184-MW-002. Monitoring well 090-MW-8A was not sampled inAugust 2006 as it could not be located following building demolition activities. Groundwater fieldparameter measurements are indicated on the groundwater sampling field data sheets in Appendix E.Groundwater contour maps are included as Figures 4C through 4E.

Total chromium was detected in the foiIowing monitoring wells above the GWQS (70 ug/L) withmaximum concentrations shown in parenthesis: 090-MW-OIO (3,500 ugIL), 090-MW-8A (380 ug/L), and184-MW -002 (222 ug/L). Hexavalent chromium was detected above the chromium GWQS (70 ugll) in

23

TIERRA-B-015034

90-MW-8A (345 ugIL), and below the GWQS in 090-MW-010 (64 ug/L). These wells are located withinthe area of chromiurp-impacted soils in the southwest portion of the Site. The most recent round ofsampling (December 2006) indicates hexavalent chromium detected in only one well: 90-MW-8A (332uglL). Laboratory analysis shows elevated pH levels at 090-MW -010 (pH 12.08), whereas near neutralpH conditions were detected at the remaining wells. Groundwater field data also indicate relativelyneutral pH values (ranging between pH 6 to 9), with the exception of090-MW-OIO in the southwestportion of the Site.

Groundwater sampling included other water quality parameters (TAL metals, natural attenuationparameters) to provide additional data tor evaluation of natural attenuation and potential groundwatertreatment options. Alkalinity values ranged from 23 mg/l to 784 mgll, with the highest alkalinity valuesdetected in 184-MW-002. Ferrous iron, sulfate, and TOC values ranged from <0.1 to 4.9 mg/I; <5 to 328mgll; and 1.6 to 47.2 mg/I, respectively. Sulfide results ranged from <1 to 32.4 mgIL. DO results rangedbetween 0 and 6 mg/l, with DO not detected in 090-MW-OIO, 090-MW-Oll, 184-MW-OOl, and 184-MW-002. ORP results indicated negative values in the majority of wells, with the lowest valuesdetected in 090-MW-OIO. Monitoring wells 090-MW-8A and 090-MW-011 (located outside the zone ofhighest hexavalent soil impact) show positive ORP values. Data for 090-MW-OIO include a lack of DOalong with negative ORP values, indicating anaerobic reducing conditions where the highest chromiumconcentrations were detected in the southwest portion of the Site. The results indicate subsurfaceconditions favorable for chromium reduction (Cr+6 to Cr+3

) in groundwater beneath the Site.

Other metals detected above the GWQS included aluminum, arsenic, iron, lead, manganese, mercury, andsodium. The greatest number of metals above the GWQS were detected in 090-MW-OIO, includingaluminum (2,920 ug/L), arsenic (58.7 ug/L), iron (12,000 ug/L), lead (80.7 uglL), mercury (28.8 ug!L),and sodium (292,000 ug/L). Elevated mercury (22.6 ugIL) was also detected above the GWQS in 184-MW-OOI. TDS and chloride concentrations ranged from 220 to 1,140 mg/l and 18 to 109 mg/l,respectively.

3.5 STUDY AREA 7 - SOURCE AREA TREATABILITY STUDIES

Honeywell has conducted a treatability assessment of source area material on the Home Depot site (seeAppendix N). Laboratory tests were conducted on soil obtained within the footprint of the formerMutual Chemical Company facility (source of Study Area 7 deep overburden groundwatercontamination) to provide a direct measure of the leachability of soil-associated hexavalent chromium(Cr(VI)) and to assess the performance of an abiotic reductant for Cr (VI). The major objectives of thisstudy were to (i) use kinetic leaching tests to determine the leaching characteristics ofCr(VI) fromrepresentative soil samples from within the source area defined by the prior wet operations on SA-5, (ii)evaluate possible Cr(VI)·mineral and/or chemical mechanisms that may be responsible for Cr(VI)retention in the soil, and (lii) evaluate the reductant dosing requirements for reduction of Cr(VI).

A full description of the studies, including the field collection, laboratory methodology and analyses, andresults is presented in Appendix N (Treatability Study - Source Area Study Area 7, HydroQual Inc.) Theresults of the studies are briefly summarized as follows:

At hydraulic gradients ranging from approximately 14 to over 70, multiple pore volume exchanges(up to 40 or more) were required to sufficiently leach Cr(VI) so that effluent concentrations werebelow the New Jersey groundwater quality criterion of70 ppb.The large number of pore volume exchanges, both within fine sand samples as well as silty claysamples, indicates that Cr(VI) is not leached within the typical 3-5 pore volume exchanges expectedif only dissolved phase chromium were present and readily leachable from the pore spaces.

24

TIERRA-B-015035

• The leaching curve response (Le., a slow, relatively steady decline) could be indicative of diffusionof Cr(VI) from within the sample, which could be accounted for by the presence of Cr(VI) inmicropores, or a combination of diffusion, sorbed material, and solid phase material.

• The fill sample that appeared to exhibit visual evidence of solid phase chromium at the time it wascollected, did not contain COPR, but did contain a chromite phase (trivalent chromium) indicatingthat the formation of solid phase material did indeed occur. Apart from this conclusion, chromiumwas detected in three of the five samples tested.

• The addition of calcium polysulfide at two times the stoichiometric ratio based on total extractableCr(VI) by alkaline digestion resulted in concentrations of Cr(VI) in effluent samples below theGWQS without indication of a return to higher levels for the sample tested with more than one dose(i.e., fine sand sample). Calcium polysulfide dose ratios for treatment should range from two to threetimes the stoichiometric ratio, based on the overall results of the testing.

3.6 CONCLUSIONS AND RECOMMENDATIONS

Soil Investigation

• The RI included over 80 borings and analysis of over 700 samples for total and hexavalent chromiumon Site 090 (Baldwin Steel), Site 184 (M.!. Holdings), and the northern portion of Site 153 (FormerMorris Canal) next to Sites 090 and 184 during the RI. The horizontal and vertical extent ofhexavalent chromium above the NJDEP Soil Cleanup Criteria has been characterized and delineated.

• The portion of the Site and proposed redevelopment area impacted by hexavalent chromiumconcentrations greater than the NJDEP soil criteria (20 mg/kg per the NJDEP chromium policy) isalong the western and southern boundaries of the Site (estimated at approximately 4.5 acres). Theimpacted area is bounded by the Site 090 (Baldwin Steel) boundary to the south (adjacent Site 117 tothe south has already been capped by Honeywell), Site 153 (Former Morris Canal) boundary to thewest (where additional RI efforts are ongoing), and clean borings (no exceedances of20 mg/kg) tothe north and east within Site 090 (Baldwin Steel) and Site 184 (M.I. Holdings). Hexavalentchromium concentrations slightly above 20 mg/kg were detected in shallow soils beneath existingpavement at a few isolated locations outside the main chromium-impacted fill area.

• A one to two foot thick layer of meadow mat (peat) is present in the western portion of the Site. Thehighest hexavalent chromium concentrations occur in saturated fill material above the meadow mat,at depths between approximately 6 to 14 feet bgs. RI results indicate good correlation between fieldobservations of possible COPR impacted soils and laboratory data indicating elevated hexavalentchromium concentrations. Field observations of possible COPR and/or COPR contaminated fill werenoted in some of the borings as relatively thin layers (e.g., yellow-green colored streaks or nodules)mainly at the bottom of the fill. Typically, the hexavalent chromium concentrations are one to twoorders of magnitude less in the underlying samples collected from (and below) the meadow mat,which appears to be acting as a confining layer that prevents downward migration of hexavalentchromium into the deeper groundwater zone.

• SPLP data for soil samples collected at SA-5 is limited and indicates high variability and uncertaintywith respect to correlation of hexavalent chromium concentrations in soils with SPLP leachateresults. The high variability of the SPLP results indicates that the SPLP test cannot be used topredict groundwater impacts at this Site. Groundwater data provides more conclusive evidenceregarding actual source impact to groundwater.

25

TIERRA-B-015036

Groundwater Investigation

• Two independent chromium contamination plumes have been identified in groundwater; one in theshallow fill and overburden zone above the meadow mat (where present) and one in the deepoverburden zone. Vertical aquifer sampling data indicate that the chromium levels in the deepoverburden groundwater zone (below the meadow mat) are several orders of magnitude greater thanthe Shallow Zone, indicating that shallow groundwater conditions at the Site are not a source of thegroundwater contamination present in the deep overburden zone.

Total and hexavalent chromium concentrations in groundwater within the Shallow Zone beneath themajority of the Site are below the GWQS or not detected. Elevated chromium concentrations abovethe GWQS ono ugIL were detected in the southwest portion of the Site (090-MW-01O, 090-MW-8A) and the northwest corner of the Site (I84-MW -002). The presence of elevated hexavalentchromium in the Shallow Zone groundwater is associated with chromium-impacted fill soils,particularly in areas with high pH levels (e.g., 090-MW-OIO; pH >10).

• Total and hexavalent chromium concentrations detected in the Shallow Zone were lower during 2006as compared to data collected during 2005. Groundwater sample results for 090-MW-OI0 indicatethat total chromium levels decreased from 5,200 ugiL (May 2005) to 3,500 uglL (December 2006),and hexavalent chromium levels decreased from 5,170 ugIL (May 2005) to 64 ugIL (May 2006) tonon-detect (December 2006). In 090-MW-8A, total and hexavalent chromium concentrationsdecreased from 514 ugll and 496 ugll (May 2005), respectively, to 356 ugll and 332 ugll (December2006), respectively. In 184-MW-002, total chromium levels decreased from 180 ug/l (May 2005) to83 ugIL (December 2006). Hexavalent chromium results during 2006 were non-detect or below theGWQS in all monitoring wells, with the exception of 090-MW -8A. The presence of elevatedhexavalent chromium in 90-MW-8A with neutral pH conditions indicates that hexavalent chromiumat this location may be associated with dichromate rather than COPR-impacted fill.

• Groundwater results indicating initial elevated total and hexavalent chromium concentrations may beassociated, at least in part, with suspension/dissolution of contaminants from physical disturbance ofchromium-impacted fill during well installation. This pattern of initial elevated concentrations nearthe time of well installation followed by substantially lower concentrations has been observed atother chromium-impacted fill sites.

• The regional groundwater investigation for SA-7 indicates that elevated chromium is present in theDeep Overburden Zone near the boundaries of Site 117 (Ryerson Steel), Site 153(Former MorrisCanal) and Site 90 (Baldwin Steel), and extends west of Route 440 in the area of SA-6 and SA-7.The source of the deep groundwater plume is believed to be from past operations at the fannerproduction plant (Site 117; Ryerson Steel; currently occupied by Home Depot), likely associatedwith historical discharges or spills of materials used at the plant (e.g., sodium dichromate) andvertical migration of chromium through the lacustrine sands into the deep overburden where it mixeswith groundwater moving through the deep, more permeable, coarse-grained sand layer.

• Other constituents detected in groundwater above the GWQS during the most recent samplingcompleted during 2006 included aluminum, arsenic, iron, lead, manganese, mercury, and sodium.

• Other constituents detected in groundwater above the GWQS in connection with investigations byothers include VOCs (benzene, xylene, TCE, DCE, vinyl chloride) and metals (cadmium, mercury,thallium) at Site 184 (MI Holdings).

26

TIERRA-B-015037

• Groundwater measurements indicate strong reducing conditions, as evidenced by lack of dissolvedoxygen and negative ORP values. These conditions favor the natural reduction of Cr+6 to Cr

H

• R1 data for the Site and nearby sites within Study Areas 5, 6 and 7 include groundwater results forchloride and TDS. Over 300 chloride and TDS sample analyses have been completed over a nine-year period, with results indicating that groundwater exceeds the GWQS for these compounds on aregional basis. In some cases, the concentrations exceed the criteria for Class IIIB groundwaterdesignation, suggesting impacts from saline surface water (Newark Bay). The exceedances of theGWQS (or Class UIB threshold values) are not bounded by property lines or location of historicaloperations, thus they are ubiquitous and regional. The level and extent of the impact varies bystratigraphic unit and is likely a function of the history and properties of each unit. In the ShallowZone (above the meadow mat), impacts are likely related to the filling of the estuarine marshes andsubsequent interconnection of the bay with the fill zone. The intermediate and deep glacial zonesand the bedrock are likely impacted from historic pumping operations. The level and extent aregoverned by geologic properties of these units (e.g. permeable zones in the glacial sediments andfracture zones in the bedrock).

Recommendations

Soil and groundwater impacts have been adequately characterized and delineated, and sufficient dataexist to proceed with remedial action selection to address chromium contamination detected in soils andgroundwater at the Site. A Remedial Action Selection Report and Remedial Action Work Plan arepresented in Sections 4 and 5, respectively.

2. No new sources of stormwater inflow shall be connected. to any separate sanitary sewers in the sewer system •.

B. Preliminary Requirements

1. Report on Maximum Treatable Flow Rates

The permittee must report to the Regional Administratorand the State agency by August 31. 1975the maximum treatable flow rates for the treatment plantor 8.r:.y complete unit process. The !r'.3.:dmum treatableflow rates must. at least, be equal to one of the following:

a. The maximum hydraulic now rate for which thetreatment plant was designed, or the maximumhydraulic flow rate for which the treatment plantcan provide partial treatment.

b. The maximum now rate that, based on historicrecords or theoretical determinations, wouldcause a treatment plant upset such that otherpermit conditions could not be achieved.

c. The ma.ximum flow rate that can be delivered tothe plant without causing seriously adverse con-ditions in the interceptor and lateral sewersystem such as substantial.property damage.

TIERRA-B-015052

~ ..Pas 5 of 28 pages

NJ0027022

2. The permittee may submit, in lieu of the above, adetailed operational plan designed to minimizepollutant discharges from the treatment and sewersystem. The permittee must demonstrate that, ifimplemented, the plan would provide for a lowerdischarge of pollutants from the system during wetweather than that occurring if the hydraulic flowwas treated during wet weather at the limiting flowrate in B. 1. above. The treatment plant andsewer system shall be operated in accordance withthis plan.

3. The permittee shall also report by August 31 1975to the permit issuance authority a proposed methodfor estimating the number and location of new sewerconnections which will be served by combinedsewers for the duration of the permit. and a pro-posed method for estimating the impact of theadditional flows generated by these new sewer con-nections on the volume of discharges from the com-bined sewer system. This method shall be used inthe development of the operational plan required inSection C. below.

c. Operational Plan

An interim operatio,nal plan designed to minimize the dischargeof pollutants from combined sewer overflo'.Vs and bypassesmust be submitted by the permittee to the Regional Admin-istrator and the State agency by re'lJruary 28. 1977The plan will prOVide for optimal coordinated operation ofthe sewage treatment plant and contributing sewer systems.The plan will specifically:

1. Refine the estimate of maximum treatable flow.

2. Report, if applicable.. the number, location. types. andkinds of regulators and their respective operating history,maintenance program. and performance efficiency.

3. Report the calculated or estimated storage capacitiesof the sewer system upstream from all control devicessuch as pump stations and regulators, or combinedsewer discharges.

4. Provide operational procedures for utilizing at least 80%of the a\'ailable capacity of interceptors and trunk linesupstream of any control devices such as pump stations,

TIERRA-B-015053

or regulators prior to any discharge from a combinedsewer overilOl'/ or bypass; or provide, if such storagecapacity utilization cannot be achieved with existing con-trol devices, the operational procedures for maximizingthe use of storage prior to any combined sewer discharge.

5. Provide a method to determine if the upstream storagecapacity was utilized prior to any discharge from~hecombined sewer system.

6. Analyze the effect on the total volume of combined sewerdischarges of new sewer connections anticipated for theduration of the permit. If these additional connectionsare expected to increase the total volume of dischargesfor like meteorological conditions, the plan must providea method for prevention of this increase by regulation orcontrol of new connectiOrlS andlor an offsetting of anyadded flows by such means as sewage and inflow reduc-tion, in-"system flow routing, and treatment and enlargementof sewer and treatment capacity.

II. IVlonitoring of Systems with Combined Sewers

A. General Requirements

Point sources 003 through . 015 areoverilows resulting when t~e hydraulic flow capacity of thesystem has been exceeded (see page 20 & 2l for a listing of thesepoint sources). These discharge points may be utilized forwet weather overflows or bypasses to the extent specified bythe approved preliminary report and interim operational plan.For all overflows the permittee is required to take the follow-ing actions:

1. Submit to the Regional Administrator and the State agencyan approvable plan for implementin~ a monitoring program,as specified herein, by August 3.1.,1975.

2. Within six months of approval of the plan required inparagraph II. A. 1.. the permittee will implement the moni-toring progra..rn to determine the location, cause, frequency,duration, quality, the quantity of wastes discharged (averageand maximum pounds per day) and the method of dischargefrom these point sources. Eifluent quantities determinedshould include at least the five day BOD, suspended solids.and fecal coliform.

TIERRA-B-015054


B. Sampling

1. Sampling requirements fot' combined ~e\Ver disch~rg~events are based on the frequency, duration or anlountof discharge. The permittee shall monitor the location.cause~ duration. and frequency of combined sewer dis-charge events to the extent necessary to determine whichsampling requirements, if any, are applicable to eachdischarge location. This monitoring shall be conductedduring a 12-consecutive-month period.

2. Adequate rainfall records in the major combined sewercatchment areas must be kept during all sampling andmonitoring re!=l.uiredin paragraphs 3 and 4 of thissection.

3. Type 1 Discharges:

a. Description

Combined sewer discharge events occurring at least20 times a year, or for a yearly total of at least90 hours, or with an estimated total volume of anydischarge. event in excess of 2.0% of the annualaverage of daily flow during the most recent yearof. record.

b. Sampling and l'\'Ionitoring Requirements

i. A record shall be maintained of the frequencyof discharge events from all Type 1 dischargelocations. The permittee must also establisha profile of at least four separate dischargeevents during the sampling year for a minimumof 250/0 of the Type 1 discharge locations. Theselocations shall be chosen so that they are, tothe extent possible, representative of all theType 1 discharge locations.

ii. The profile shall be established as follows:

Discrete samples shall be collected and corres-ponding rates of £10\'1 shall be recorded withinthe first five minutes after the start of the dis-charge event. and during each 15 minute intervalup to 90 minutes or the end of the discharge,whichever comes first.
