The investigation of the Nonsource Areas focused on targeting none of the areas that were

associated with a specific source of contaminatio n. The samples from the Nonsource Areas were

collected randomly across the SMS Site to assess whether contamination within the surface soil

was contained to a specific area or had migrated to other areas of the site and to determine if this

5.1.2 Sediment

The sediment investigation at the SMS Site was conducted in Lake Sabine, adjacent to both the

SMS Site and the Palmer Barge Line Site and was referred to as the “off-site” investigation area.

The purpose of the investigation was to characteri ze the vertical and lateral extent of off-site

sediment contamination within the area of influe nce from the site. The off-site area was broken

into three subareas based on distance from the shor eline: intertidal, nearshore, and offshore. The

intertidal area represen ted exposed sediments from the top of the bank along the shoreline to

approximately the mean lower low water mark. The nearshore area was irregular in shape and

encompassed both shallow sediments and those clos e to potential upland or on-site sources.

Both surface and subsurface sediment samples were collected in the nearshore area. The

offshore area was a rectangle approximately 150 to 200 ft wide paralleling the navigation

channel and representing the area most heavily influenced by ship traffic. Samples were

collected in all three off-site areas from the su rface at 0 to 6 in. in de pth. Subsurface samples

were collected from only the nearshore area from depths up to a maximum of approximately 4 ft.

# 5-14 A complete summary of COPEC for all media at th e SMS Site, including the off-site sediment, is

presented in Table 5-17.

The discussion below focuses on surface samples collected in the intertidal region, surface and

subsurface samples collected in the nearshore area, surface samples collected in the offshore

area, and all sampling locations grouped together in one exposure area. All sediment samples

were analyzed for BNAs, metals, and Tri butyltin (TBT). The average and maximum

concentrations for each constituent were comp ared to SBVs in sediment and background

screening values. All values were separated into four categories consisting of marine

benchmarks, freshwater benchmarks, backgrou nd area screening values, and simultaneously

extracted metals/acid volatile sulfide (SEM/AVS) ratios.

The marine benchmarks included the Calcasieu Es tuary Investigation Baseline Ecological Risk

Assessment (BERA) ER-M value, the BERA PEL value for sa ltwater, the NOAA Effects Range

Low (ER-L) value, the NOAA Apparent Effects Threshold (AET) value, and the TCEQ

Sediment Benchmarks for saltwater.

The freshwater benchmarks included the BERA Freshwater Consensus Based Probable Effect

Concentration (FWCONPEC), the NOAA PEL va lue for freshwater, and TCEQ sediment

benchmarks for freshwater.

The background area screening valu es were obtained using sample s collected adjacent to the

Sydnes Island during the WESTON RI (either a or b). The background screening values were

only established for metals.

The toxicity of divalent metals in sediments is directly related to the am ount of sulfide present,

as the metals form insoluble sulfides and are not bioavailable to ecological receptors. The ratio

of SEM to AVS (presented as AVS/SEM) is used to determine whether metals in sediments are

bound with sulfides or are not bound and therefor e pose a threat to ecological receptors.

AVS/SEM ratios below one are generally considered to be at non-toxic levels regardless of

whether their benchmarks were ex ceeded, while ratios greater than one may show these metals to

be present at levels indicative of toxicity. Cadmium, copper, lead, nickel, and zinc are the

A complete summary of COPEC for all media at the SMS Site, including the groundwater, is

presented in Table 5-17.

Six monitoring wells were installed at three diffe rent locations within the upland area of the SMS

Site (see Figure 3-2). A pair of shallow and deep monitoring we lls was installed at each location

(SM061, SM068, and SM116). An “A” following the well location identifies the deep wells

(down to 60 ft) and a “B” identifies the shal low wells (down to 30 ft). Groundwater samples

were collected from each monitoring well during two separate sampling events, one in October

2001 and one in June 2002. October samples were analyzed for BNAs, metals, butyl-tins, and

# 5-21 Volatile Organic Compounds (VOCs) while June 2002 samples were analyzed only for total and

dissolved metals (no butyl-tins or cyanide). Th e detected concentrations of each constituent

from both rounds of sampling were compared to the groundwater ecologi cal SBVs to assess

possible impacts from the discharge of groundwater to surface waters in Lake Sabine as the most

likely ecological exposure pathway to the groundwate r. For purposes of assessing these impacts,

a factor of 10 was first applied to the groundwater SBVs. This methodology was discussed with

NOAA’s Coastal Resource Manage r, Ron Gouguet, during work plan and scoping meetings on

the SMS Site as an approach to assessing possi ble ecologically related groundwater to surface

water impacts. The appropriate referen ce for this methodology was cited from the NOAA

SQuiRTs (Buchman, 1999). A comp lete summary of the ecological benchmarks that were used

for screening upland groundwater is presented in Table 4-3.

The discussion of results that follows below focuses on any obvious differences between the

October and June sampling events. Results fr om individual wells within each station and

between stations are contrasted in an effort to characterize possible differences within the

shallow and deep groundwater zones and between the different sources areas.

The complete groundwater screening results fo r the October 2001 sampling event are presented

in Table 5-15. Screening results (presented as risk ratios) for the June 2001 sampling event are

presented for both total a nd dissolved metal concen trations in Table 5-16.

5.1.3.1 October 2001

Differences between station locations indicate a “slight” possibility of higher concentrations

occurring at station SM061. No obvious differen ces are apparent betw een shallow “A” wells

and the deeper “B” wells based on the result s from the October 2001 sampling event. Ten

where several benchmarks were exceeded in the shallow well but not in the deeper well. There

also does not appear to be any major differences between the different station locations. A

significant number of constituents including al uminum, beryllium, iron, and lead were dropped

from the COPECs list during the June 2002 sampli ng event when compared to the same results

from the October 2001 sampling event. In the J une sampling event, bari um and the “naturally

within the June sampling event was the loss of calcium and iron from the dissolved fraction.

However, as noted in Table 5-16, the risk rati os for all the COPECs, except for barium and

magnesium, were considered to be minimal fo r this screening evalua tion (less than 10).Northern BobwhiteeWhite-footed MousefLower Range Upper Range2-MethylnaphthaleneBNA mg/kg 2.91E-011.10E-01--------------AcenaphtheneBNA mg/kg 1.40E-011.10E-012.00E+01------------AcenaphthyleneBNA mg/kg 5.74E-011.80E+00--------------AcetophenoneBNA mg/kg3.52E-014.80E-02--------------AnthraceneBNA mg/kg6.87E-012.00E+001.00E-01------------BenzaldehydeBNA mg/kg 3.51E-014.00E-02--------------Benzo(a)anthraceneBNA mg/kg6.08E-012.00E+001.20E+00------------Benzo(a)pyreneBNA mg/kg5.94E-011.90E+001.00E-01------------Benzo(b)fluorantheneBNA mg/kg 8.49E-013.00E+001.20E+00------------Benzo(g,h,i)peryleneBNA mg/kg 8.28E-012.50E+00--------------Benzo(k)fluorantheneBNA mg/kg 3.10E-011.10E+001.20E+00------------bis(2-Ethylhexyl)phthalateBNA mg/kg 3.66E+004.90E+00--------------CarbazoleBNA mg/kg 2.02E-016.30E-01--------------ChryseneBNA mg/kg 1.10E+003.80E+001.20E+00------------Dibenz(a,h)anthraceneBNA mg/kg 1.74E-012.40E-011.20E+00------------DibenzofuranBNA mg/kg 1.67E-016.90E-02--------------Di-n-octylphthalateBNA mg/kg3.93E-011.80E-01--------------FluorantheneBNA mg/kg8.27E-012.50E+001.00E-01------------FluoreneBNA mg/kg 1.75E-011.70E-013.00E+01------------Indeno(1,2,3-cd)pyreneBNA mg/kg3.76E-011.00E+001.20E+00------------NaphthaleneBNA mg/kg2.05E-011.70E-011.00E-01------------PhenanthreneBNA mg/kg4.20E-011.40E+001.00E-01------------PyreneBNA mg/kg9.29E-012.80E+001.00E-01------------AluminumMETAL mg/kg1.54E+042.06E+045.00E+00------4.50E+033.00E+044.96E+03AntimonyMETAL mg/kg4.20E+002.05E+015.00E-01--------1.00E+00--ArsenicMETAL mg/kg5.86E+007.40E+002.50E-01----1.10E+001.67E+015.90E+004.70E+00BariumMETAL mg/kg3.49E+025.34E+025.00E+00------4.30E+023.00E+022.84E+02BerylliumMETAL mg/kg4.83E-015.70E-011.00E-01----5.00E-012.00E+001.50E+004.50E-01CadmiumMETAL mg/kg2.68E-018.30E-012.00E-013.85E+014.14E-011.00E-021.00E+00----Calcium METAL mg/kg 8.68E+031.19E+04------------3.06E+04ChromiumMETAL mg/kg1.62E+012.74E+014.00E-015.36E+011.02E+06--3.80E+011.00E+018.80E+00CobaltMETAL mg/kg5.08E+006.90E+002.00E+01------8.00E+007.00E+003.70E+00CopperMETAL mg/kg5.90E+019.86E+011.00E+001.87E+034.13E+02--2.00E+011.50E+019.50E+00Cyanide, TotalMETAL mg/kg1.85E-014.80E-019.00E-01----------2.10E-01IronMETAL mg/kg 2.19E+043.40E+042.00E+02--------1.50E+041.03E+04LeadMETAL mg/kg1.23E+022.10E+024.60E+001.91E+005.55E+001.00E+011.80E+011.50E+012.02E+01Magnesium METAL mg/kg 1.51E+031.73E+03------------2.26E+03ManganeseMETAL mg/kg3.08E+023.91E+021.00E+02----3.89E+028.50E+023.00E+022.84E+02MercuryMETAL mg/kg9.74E-021.60E-015.10E-042.51E+021.93E+02--1.00E-014.00E-027.00E-02NickelMETAL mg/kg4.71E+015.38E+012.50E+015.11E+031.07E+04--1.60E+011.00E+011.12E+01Potassium METAL mg/kg 1.06E+031.22E+03------------1.35E+03SilverMETAL mg/kg1.46E+002.60E+002.00E-02----1.00E-025.00E+00--4.17E-01Sodium METAL mg/kg 4.67E+027.23E+02------------4.62E+02VanadiumMETAL mg/kg1.88E+012.64E+012.00E+00------6.60E+015.00E+011.42E+01ZincMETAL mg/kg2.76E+024.38E+029.00E-013.59E+032.15E+022.20E+015.00E+013.00E+014.47E+01Notes:aAverage concentration represent an average of all surface soil concentrations from all locations within the defined exposure area and is based on either the 95%UCL or the arithmetic average if the 95%UCL was less than the arithmetic average or greater than maximum detected concentration.Table 5-1Surface Soil Ecological Screening Results (Waste Water Impoundment Area)MaximumConcentrationbConstituentsData Group UnitsAverageConcentrationaLiterature-BasedScreeing BenchmarkValuescWildlife Food-Chain BenchmarksdTCEQ MedianBackground ValuehSite-SpecificBackground ValueiBackground Soil Screening ValuesEPA Region 6g5/6/2003: 10:58 AMState Marine Soil Summary Tables - Ecological.xls: Tables 3-1 and 5-1Northern BobwhiteeWhite-footed MousefLower Range Upper RangeTable 5-1Surface Soil Ecological Screening Results (Waste Water Impoundment Area)MaximumConcentrationbConstituentsData Group UnitsAverageConcentrationaLiterature-BasedScreeing BenchmarkValuescWildlife Food-Chain BenchmarksdTCEQ MedianBackground ValuehSite-SpecificBackground ValueiBackground Soil Screening ValuesEPA Region 6gbMaximum concentration represents the highest detected surface soil concentration from a single location.
