SUMMARY OF SAMPLING EVENTS 2003-2008

2003 Surface Sediment and Core Data

A total of 178 surface sediments samples (0-5 cm) were collected in October of 2003 All sediment samples were analyzed for total mercury (Hg) methyl Hg (MeHg) and Total Organic Carbon (TOC) Three sediment cores were also collected in October 2003 one from Reservoir 2 in an area with historically high Hg levels and two from the Charles River reference area Four depth intervals (0-3 cm 3-6 cm 6-9 cm and 9-12 cm) were sampled from each core to evaluate changes in Hg concentrations at depth The surface sediment data are summarized in Table 1 and the sediment core data are summarized in Table 2 Figures 1 2 3 3A 3B 4 5 5A 6 7 8 9 10 11 and 12 show the sediment sampling locations

2003 Surface Water Data

Seventy surface water samples were collected from locations that were either in the flowing or riparian wetland reaches of the Sudbury River and the Charles River Samples were collected by wading or from a boat Water was collected at a depth of about 20 cm and analyzed for unfiltered total Hg and MeHg The surface water data are summarized in Table 3 Figures 1 2 3 4 5 6 7 8 9 10 11 and 12 show the surface water sampling locations

2005 Surface Sediment Data

Surface Sediment samples (0-5 cm) were collected along eight transects in Reservoir 2 and at one discrete sample (S3-3-SDXX0001-0-051011-0005) collected from the cove area to the right of the dam on November 11 2005 Five surface sediment samples were collected along each of the eight transects All five samples were composited and an aliquot was analyzed for total Hg MeHg and TOC Four discrete surface sediment samples were collected from Heard Pond on November 12 2005 These samples were also analyzed for total Hg MeHg and TOC The surface sediment data are summarized in Table 4 Figure 3 shows the discrete sample collected in the embayment Figure 3C shows the Reservoir 2 transect locations and Figure 7 shows the Heard Pond sample locations

2005 Sediment Core Data

Sediment cores were collected on December 5 and 6 2005 and on December 12 2005 Three sediment cores were collected along three transects in the Sudbury River at the Great Meadows National Wildlife Refuge (GMNWR) on December 5 and 6 2005 and eleven sediment cores were collected on December 12 2005 Eight of the eleven sediment cores were collected from the center of the eight transects in Reservoir 2 The three remaining cores (not from transects) were collected along the Sudbury River Each sediment core was cut into four sections (0-5 cm 5-10 cm 10-15 cm and 15-20 cm) A portion of each core section was analyzed for total Hg MeHg TOC and grain size The 0-5 cm layer of these cores consisted mostly of decomposing organic material Sediment core data are summarized in Table 5 and grain size results are in Table 6 Figures 3C and 3D show the Reservoir 2 core locations and grain size and Figures 7A 7B 8A and 8B show the Sudbury River and GMNWR core locations

2005-2008 Low-Level Mercury Sampling Effort

Surface water sediment plankton (combination of phyto- and zooplankton) and small fish tissue samples were collected from Reservoir 2 Reservoir 1 and GMNWR for total Hg and MeHg analysis Sampling started in 2005 and stopped in the Fall of 2008 Surface water and plankton samples collected in 2005 and 2006 helped develop a low-level Hg surface water and plankton sampling technique and general sampling protocol Low-level Hg sampling events based on the general sampling protocol were conducted in May 2007 June 2007 July 2007 September 2007 October 2007 March 2008 and June 2008

Surface water Three surface water samples from Reservoir 2 and GMNWR and two surface water samples from Reservoir 1 were collected during each of the low-level Hg sampling events Surface water samples were collected using a peristaltic pump to simulate continuous flow conditions The ldquoclean hands - dirty handsrdquo (CH-DH) sampling technique was used to minimize sample contamination Surface water data are summarized in Table 7 Figures 13 and 13A show the surface water sampling locations

Plankton Two plankton samples were collected at one of the surface water sampling locations along Reservoir 1 Reservoir 2 and GMNWR during each low-level Hg sampling event One plankton sample was submitted for total Hg and MeHg analyses and the other was retained for future taxonomic identification The CH-DH sampling technique was used to minimize sample contamination Plankton data are summarized in Table 7 Plankton samples were collected at the middle station for Reservoir 1 (S3-SW-2) and GMNWR (S8-SW2) and either S4-SW1or S4-SW2 for Reservoir 2 Figures 13 and 13A show the plankton sampling locations

Sediment Sediment samples were collected in September 2008 The goal was to collected sediment within the weeks of surface water and fish sampling all in similar locations Eight surface sediment samples (0-5cm) with two duplicates were collected Sediment samples were analyzed for total Hg and MeHg The sediment sampling locations correspond to the surface water sampling locations Sediment data are summarized in Table 8 Figures 14 and 14B show the sediment sampling locations

Fish EPA and ESAT collected 64 yellow perch and 39 largemouth bass samples in reaches 3 9 and 10 of the Sudbury River on June 5 and 11 2008 Target areas were the same as water and sediment (see Figures 13 and 13A) Fish samples were collected and processed in accordance with the original Quality Assurance Project Plan (QAPP) for the Nyanza OU IV site prepared by Avatar Environmental Otoliths and scales were removed from the perch and bass and were stored until sent to Philadelphia Academy of Natural Sciences Philadelphia PA for aging The bass had one fillet removed their stomach contents were examined and recorded when recognizable Frozen bass fillets and frozen whole body perch were shipped to Brooks Rand Laboratory (BRL) Seattle WA for total Hg analysis Fish data are summarized in Table 9

2008 Soil Samples Soil samples were collected from eight different locations using a plastic disposable scoop at each location These samples were collected to provide the model with information regarding watershed soils Each soil sample was a composite of 4 or more surface soil grab samples (0-6rdquo) The grab samples were homogenized and an aliquot was analyzed for total Hg and MeHg Table B provides details about the property around each soil sample Soil data are summarized in Table 10 Figure 15 shows the soil sampling locations

Table B Soil sample locations details

Sample Location Property Details

Location 1 Large State-owned property mixed open field and trees Sample is a composite grab near the shore of Reservoir 1 in a stand of mature white pines No sign of recent development in immediate area

Location 2 Fountain Street on western shore of Reservoir 2 in Framingham Sample was taken in the 20 buffer zone for the reservoir in an open grassy area adjacent to shore

Location 3

Pleasant Street in Ashland MA upstream of the Nyanza site Sample was taken in the back yard of a VFW Hall near the Ashland Commuter rail station The sample location is near the Rivers edge in sparse shrubs Evidence of urban fill nearby Entire area is fairly developed

Location 4

In a wetland edge behind Wayland High School The sample location is in the wetland that separates the school fields from the River in the vicinity of Heard Pond but on the opposite shore Area may very occasionally be flooded with Sudbury River water during extreme high water

Location 5 Carol Gretchell Nature Trail in Saxonville (part of Framingham off Sudbury Landing Road This area is near a new development and while in protected land may have seen some development in the past

Location 6 Off Route 20 in WaylandSudbury area off the access road to the SudburyWayland town dump Area is wooded Trees are mature indicating

4

Sample Location Property Details no recent development

Location 7 Great Meadows National Wildlife Refuge - on a hill above Refuge Headquarters ramp Wooded area with little understory - above high water and presumably representative of upland soils in Refuge areas

Location 8 Off Route 117 in Wayland in mixed pineoakmaple forested area approximately 100 yards off Route 117 which serves as a canoe access point Soil is 1-2 of organic material over glacial fine sand

2008 Total Suspended Solids Sampling Water samples were collected for Total Suspended Solids (TSS) analysis from 34 segments in the Sudbury River Sampling was performed over four days in November 2008 (111108 111208 111308 and 111808) An effort was made to collect water samples in the middle of each segment to stay consistent GPS coordinates site accessibility water quality parameters and pictures were taken or recorded for each of the 34 segments when possible Segments 8 and 21 were resampled after a weekend of rain in order to compare them to the TSS results of the same sites sampled before rain Water quality parameters were taken at sites 1-7 but were lost due to an unexpected circumstance Water quality parameters were not measured at sites 8 and 9 due to time constraints or at sites 10 to 20 because the water was too shallow Note also that when analyzing for TSS 800 mL of water was analyzed instead of 400mL as was done in the past to avoid non-detects The TSS results are summarized in Table 11 Figure 16 shows the surface water sampling locations

CONCLUSION

Several sampling events have been conducted in support of the mercury modeling effort for the Nyanza Chemical Superfund Site ndash Operable Unit IV (Sudbury River) All of the analytical results and maps associated with these sampling events between 2003 and 2008 have been compiled in order to provide organized and concise data summary

INTRODUCTION

The Environmental Services Assistance Team (ESAT) was tasked with summarizing several sampling events that have occurred in support of the mercury modeling effort for the Nyanza Chemical Superfund Site ndash Operable Unit IV (Sudbury River) This memorandum briefly describes each sampling event provides a map of the sampling locations and summarizes the analytical results Table A provides an overview of the ten reaches and reference areas that were studied from 2003 to 2008 All of the sampling events are summarized below in chronological order and by media type (ie sediment surface water)

SUMMARY OF SAMPLING EVENTS 2003-2008

2003 Surface Sediment and Core Data

A total of 178 surface sediments samples (0-5 cm) were collected in October of 2003 All sediment samples were analyzed for total mercury (Hg) methyl Hg (MeHg) and Total Organic Carbon (TOC) Three sediment cores were also collected in October 2003 one from Reservoir 2 in an area with historically high Hg levels and two from the Charles River reference area Four depth intervals (0-3 cm 3-6 cm 6-9 cm and 9-12 cm) were sampled from each core to evaluate changes in Hg concentrations at depth The surface sediment data are summarized in Table 1 and the sediment core data are summarized in Table 2 Figures 1 2 3 3A 3B 4 5 5A 6 7 8 9 10 11 and 12 show the sediment sampling locations
