DATA SUMMARY REPORTAREA 14 SUPPLEMENTAL SEDIMENT SAMPLINGWESTINGHOUSE ELECTRIC (SHARON PLANT)

SHARON, PENNSYLVANIA

1.0 INTRODUCTION

Cummings/Riter Consultants, Inc. (Cummings/Riter) was retained by CBS Corporation(CBS) to conduct supplemental sampling of sediment in the vicinity of the ConsumersPennsylvania Water Company - Shenango Division plant along the Shenango River inSharon, Pennsylvania. This work was performed in accordance with the Feasibility StudySupplemental Sampling and Analysis Plan for Groundwater, Sediment, and Non-AqueousPhase Liquids (Cummings/Riter, October 22,1998) and the Revised Sampling and AnalysisPlan Addendum (Cummings/Riter, April 12,2000). These documents were reviewed andapproved by the Pennsylvania Department of Environmental Protection and the U.S.Environmental Protection Agency (USEPA).

The purpose of this supplemental sampling was to obtain additional data on the quantity andquality of sediment immediately upstream of the dam adjacent to the water plant, particularlyWith respect to the presence of polychlorinated biphenyls (PCBs). This additional data willbe used in finalizing the range of potential remedial alternatives for sediment described in thefeasibility study report.

During previous sampling events in this area (identified as Area 14), no samples had beencollected within 150 feet of the dam, due to potential safety concerns associated withsampling near the submerged dam. These safety concerns were mitigated during this eventby coordinating the activities with the U.S. Army Corps of Engineers so that flows releasedfrom the Shenango Reservoir four miles upriver were reduced. Additionally, a rope wassecured across the river upstream of the sampling area, to which the sampling boat wasattached at all times as a lifeline.

Field sampling activities were performed on April 18 and 19, 2000 by Cummings/Riter and —XAquatic Systems Corporation (a service of McLaren/Hart). This Data Summary Reportprovides a description of sediment sampling procedures and locations, as well as a briefoverview of the findings of the sampling event with regard to both analytical results and thegeneral composition and presence of sediment at the various sampling locations.

2.0 SAMPLING AND ANALYSIS PROCEDURES

24 SEDIMENT SAMPLING LOCATIONSAs described in the April 2000 Addendum, samples were originally intended to becollected at a total of 10 to 12 locations. Samples were to be collected near each bank ofthe river as well as at the center of the channel, at approximate 25 to 30-foot intervalsupstream of the dam. Samples were to be collected from the following depth intervals:i

• Zero to six inches below the riverbed,• Six to twelve inches below the riverbed, and• Each subsequent twelve-inch depth interval to a maximum depth of six

feet below the river bed, or until corer refusal was reached, indicatingthe bottom of the sedimentary material.

An attempt was made to collect samples at ten locations, including four locations alongthe east bank of the river, two along the west bank, two at midstream, and two midwaybetween the east bank and midstream locations (Figure 1). Samples were collected usinga pre-cleaned, stainless-steel, two-inch diameter split-spoon sampler with slide hammer.Two or three samplers were driven at each location. Depths to refusal ranged from 6 to48 inches.

The material recovered from these ten locations consisted primarily of coarse gravel tocobble-sized rocks, with slag-like material, ballast stone, brick fragments, anddecomposing organic material recovered at some locations. The amount of materialrecovered from each sampler was typically less than three inches. The material recoveredfrom seven of the ten locations was placed in sample containers and submitted toLancaster Laboratories for analysis, as described in Section 2.2. Material recovered fromthe other three sample locations consisted of only rock and slag fragments, and were thusnot sampled. Separation of the samples into depth intervals as described above could notbe performed, due to the limited recovery from each core.

Additional samples were collected at two locations in the general vicinity of 1998 sampleIdeation SD-14E2, which was found at the time to contain 52 milligrams per kilogram

UMMINGS

-3- ftR302366

(mg/kg) total PCBs in the shallow (zero to six inch) sample interval. Sample locationSD-E24 was collected approximately 10 to 15 feet upstream of sample location SD-14E2,while location SD-E25 was collected about 35 feet upstream of SD-E24.

At each of these two additional locations, samplers were driven to about four feet, withabout five inches of material recovered during each attempt. This material generallyconsisted of a very stiff clay, with some decomposing organic material near the surface.As with the samples collected near the dam, the recovered material could not be separatedinto depth intervals due to the limited amount of recovery. A stainless-steel ponar wasused to collect shallow sediment (zero to six inches) at location SD-E25. No shallowsediment could be collected from location SD-E24 using this method. The recoveredmaterial was placed in sample containers and submitted for laboratory analysis.

Photographs of the sample locations and collected material are provided in Appendix A.Sample collection forms are included in Appendix B.

The approximate sediment sample locations were surveyed by Cummings/Riter usingglobal positioning system equipment with a typical accuracy of one to two centimeters.

2.2 LABORATORY ANALYSISSediment samples were placed on ice in coolers and submitted to Lancaster Laboratoriesto be analyzed for PCBs by USEPA Method 8082, priority pollutant metals by contractlaboratory procedure methods, total organic carbon (TOC) by USEPA Method 415.1, andgrain size distribution by ASTM Method D422. Due to the limited amount of samplematerial available, quality assurance samples required by the Supplemental Sampling andAnalysis Plan, including duplicate and matrix spike samples, could not be collected.

Based on discussions with the laboratory, the seven samples submitted from, the vicinityof the dam had insufficient material to run a grain-size analysis as well as the chemicalanalyses. Further discussions revealed that the laboratory's standard procedure is tomanually remove particles larger than about 0.25 inch from samples, as the largerparticles cannot be analyzed in a manner which would be representative of the entiresample. (For comparison, gravel is defined by the United Soil Classification System as

-4-

particles larger than 0.187 inch.) Thus, CBS instructed the laboratory to screen the sevensamples using a 0,236-inch sieve, recording the weight of the sample both retained on thescreen and passing through. The material which passed through the sieve was thenanalyzed for PCBs, metals, and TOC. For three of these seven samples, chemicalanalyses could not be performed because insufficient material passed through the( .236-inch sieve.

Of the three samples collected from locations SD-E24 and SD-E25, only sediment sampleSD-E25A was of sufficient quantity that both the grain size and chemical analyses couldbe performed as planned. Grain size analyses were not performed on the other twosamples from this area, however the grain-size distribution for these two samples wouldbe expected to be similar to SD-E25A based on visual characterization.

3.0 ANALYTICAL RESULTS

Sediment sample data was compared to the effects range low screening level criteria asdescribed in the Screening Level Ecological Risk Assessment (ERA, ChemRisk®, June 6,1997). An ecological effects quotient (EEQ) can be calculated by dividing the individualsample result by the corresponding screening level criterion. The calculated EEQ valuecan then be correlated to potential risk to ecological receptors as follows (from theScreening Level ERA):

• EEQ less than one - No potential risk to ecological receptors.• EEQ between one and ten - Potential risk to ecological receptors.• EEQ between 10 and 100 - Moderately high potential risk to

ecological receptors.• EEQ greater than 100 - Extreme potential risk to ecological receptors.

Summary analytical data for samples collected from Area 14, including samples collectedfrom the area in 1998, are provided in Table 1. Sample locations and total PCBconcentrations are shown on Figure 1. Laboratory data packages for samples collectedduring this event are provided in Appendix C. A summary of the data is provided below.As PCBs are believed to be the primary site-related constituent of concern, the summarywill focus on the PCB data with a brief summary of the metals data.

As described in Section 2.0, the presence of fine-grained sediment immediately upstreamof the dam appears to be rather limited. For the three samples nearest the dam whichcould be analyzed (SD-W20A, SD-W21 A, and SW-K20A), total PCB concentrationswere all less than 0.4 mg/kg (EEQs of less than eight). The only other sample from thevicinity of the dam which could be analyzed (SD-E23A) had a total PCB concentration of5.55 mg/kg (EEQ of 111). Each of these four samples was screened using a 0.236-inchsieve, with the percentage of material passing the sieve ranging from 9.1 to 26.7 percent.

For the three samples collected from the vicinity of 1998 sample location SD-14E2, totalPCB concentrations ranged from 0.23 to 8.15 mg/kg (EEQs of up to 163). The results of

SWIMMINGS

-6- flR302369

these three samples are generally consistent with the 1998 samples, in that they confirmthe presence of a small area with high PCB concentrations relative to the ecologicalscreening levels.

Metals concentrations for the seven samples which could be analyzed indicatedexceedances of the screening level criteria for chromium (one sample exceeding thecriterion with a maximum EEQ of 1.1), lead (five samples with a maximum EEQ of 19),mercury (two samples with a maximum EEQ of 3.9), nickel (two samples with amaximum EEQ of 2.1), and zinc (six samples with a maximum EEQ of 4.3).

Data presented in Table 1 for the April 2000 sampling event has not been validated.Results of validation for this data will be incorporated into the final feasibility studyreport.

5.0 SUMMARY

Field observations and a review of the analytical data from the supplemental samplingactivities performed in April 2000 are summarized as follows:

• The presence of fine-grained sediment immediately upstream of thedam appears to be very limited. Material recovered by the corersindicated the bottom of the river in this area consisted largely of coarsegravel, cobbles, and other large-diameter material. The material thatwas recovered and could be analyzed had total PCB concentrations ofless than 0.4 mg/kg. Concentrations of total PCBs in backgroundsediment samples collected in 1998 ranged from not detected to 0.62mg/kg.

• The presence of one area of sediment containing higher concentrationsof PCBs along the eastern bank of the river directly across from thewater company was confirmed by this sampling event. This areaappears to begin approximately 100 feet upstream of the dam andextends about 250 to 300 feet further upstream. Included within thisarea is a sample collected in 1998 which had a total PCB concentration » jof 52 mg/kg.
