Human Health Risk Assessment – State Marine 

Superfund Site 

The following sections present the approach, assumptions, and conclusions of the baseline 

human health risk assessment (HHRA) for the State Marine Superfund Site. The approach 

and assumptions presented below are consistent with the EPA-approved Human Health 

Risk Assessment Work Plan for the Site (CH2MHILL, 2005). In accordance with the Work 

Plan, a statistical comparison of onsite concentrations to measured background levels was 

performed for inorganic analytes using a central tendency comparison. Results are 

incorporated into the HHRA. 

In summary, dieldrin and heptachlor epoxide were identified as constituents of concern 

(COCs) in soil in the Maintenance Shed Area and the Nonsource Areas, respectively. These 

chemicals, which were only detected in a few locations on-site, are not expected to be 

associated with site activities, but background concentrations were not available for 

comparison. In addition, copper, zinc, and Aroclor 1242 were identified as COCs in 

sediment, based on protection of fish ingestion exposures. However, the modeled fish 

tissue concentrations used in this HHRA are much higher than the measured fish tissue 

concentrations from Lake Sabine as reported by the Texas Department of Health (TDH) and, 

therefore, are expected to be overly conservative. 

1. Data Used in the HHRA 

• Soil - All historical soil data that were available to CH2M HILL electronically as of June 

17, 2005, were used in the HHRA. The available data consisted of soil samples collected 

in 1995 and 2001 from various areas, including six “hot spot” areas that were identified 

during the 1995 Expanded Site Inspection (ESI) (TNRCC, 1996) and 2001 Remedial 

Investigation (RI) (Weston, 2001) based on historical activities performed in six distinct 

areas. The data were grouped for the HHRA based on the groupings presented in the 

1995 ESI and the groupings provided in the 2001 RI Report (Weston, 2001). It should be 

noted that during the 1995 ESI, soil samples were grouped by areas potentially impacted 

by the potential sources and included areas outside the immediate source boundaries. 

The following data groupings were used in the HHRA: 

− Wastewater Impoundment Area 

− Wastewater Treatment Facility 

− Tar Burn Area 

− Current Aboveground Storage Tank Area 

− Maintenance Shed Area 

− Lauren Tank Farm 

− Non-Source Area 

• Groundwater – Groundwater data were not used in the HHRA due to the lack of 

groundwater receptors (groundwater is not used as a potable source, chemicals of 

potential concern are inorganics and semi-volatile organic compounds, and no 

groundwater seeps were observed during the Site reconnaissance visit on June 17, 2005). 

005336
HUMAN HEALTH RISK ASSESSMENT VERSION 1.0 – STATE MARINE SUPERFUND SITE 

PROJ\USEPA\331756\TASK 7-RA\SM_HHRA_VERSION 1.0.DOC 2 

• Surface Water – Surface water data were not used in the HHRA. Although one surface 

water sample was available, the methodology used for its collection reflected 

groundwater quality rather than surface water. 

• Sediment – All historical sediment data collected from the 0-6 inch interval and 

available to CH2M HILL electronically as of June 17, 2005 were used in the HHRA. The 

available data consisted of sediment samples collected in 1995 and 2001. All sediment 

groupings previously identified in the 1995 and 2001 data sets were combined into one 

sediment grouping. The sediment data were used to model edible fish tissue 

concentrations. 

• Fish – Historical edible fish tissue data available for Sabine Lake are discussed in the 

Uncertainty Section (Section 9). The data were collected by TDH in 1995. 

2. Potential Receptors 

The following realistic receptors were identified onsite and near the Site and were evaluated 

for significant exposure pathways in the HHRA: 

• Current onsite – industrial/commercial worker (Site owner), adult trespasser (although 

very infrequent since the Site is remote in relation to residential areas) 

• Current offsite – adult or child eating fish caught in Lake Sabine 

• Future onsite – industrial/commercial worker, construction worker, and adult 

trespasser (although very infrequent since the Site is remote in relation to residential 

areas) 

• Future offsite – adult or child eating fish caught in Lake Sabine 

Direct contact exposures to sediment were not quantified since there are currently no 

complete exposure pathways for sediment, and the Jefferson County Navigation District has 

no plans to dredge sediments immediately adjacent to the Site. The nearest dredging will 

occur approximately 500 feet from the Site shoreline. 

The conservative draft human health Conceptual Site Model (CSM) presented in the 2001 RI 

Report was revised to reflect more realistic current and future exposure scenarios. The CSM 

presents potential chemical sources, release mechanisms, receptors (current and future), and 

exposure routes, and is provided in Table 1 of Attachment 1. 

3. Chemical of Potential Concern Selection Process 

The chemicals of potential concern (COPCs) were identified for soil and sediment by a 

three-step screening process that evaluated: 1) frequency of detection, 2) background 

concentrations, and 3) risk-based screening levels. In addition, chemicals that were 

considered essential nutrients (calcium, magnesium, potassium, and sodium) were not 

selected as COPCs. 

3.1 Step 1: Frequency of Detection Evaluation 

The frequency at which each chemical was detected was evaluated. Those constituents 

detected at a frequency of 5 percent or less in soil or sediment were eliminated from the 

005337
HUMAN HEALTH RISK ASSESSMENT VERSION 1.0 – STATE MARINE SUPERFUND SITE 

PROJ\USEPA\331756\TASK 7-RA\SM_HHRA_VERSION 1.0.DOC 3 

HHRA. Those constituents detected at a frequency greater than 5 percent were carried to 

Step 2 of the COPC screening process. 

3.2 Step 2: Comparison to Background 

A statistical comparison was made of Site concentrations to background levels of inorganics. 

The following sources of background data were used in the comparison: 

• Soil – site-specific background data collected in 1995 during the ESI and in 2001 during 

the RI; 

• Sediment – background data collected in Sabine Lake (in an area unimpacted by the 

Site) in 2001 during the RI. 

The background comparison included the following components: 

• Graphical Comparison – Box and whisker plots were prepared for visual comparison of 

Site and background data. 

• Central Tendency Comparison – Nonparametric Wilcoxon Rank-Sum test performed to 

determine whether an average shift of the Site data population appeared to exist relative 

to the background data population. 

• Comparison to Background Threshold Value - Upper tolerance limits (UTLs) and 

Prediction Limits were calculated to estimate the upper tail of the background 

population. These are presented as auxiliary statistics in this study while the conclusions 

from the Wilcoxon Rank Sum are used for risk decisions. 

• Final Data Evaluation – After the preliminary conclusions were developed, the 

background dataset underwent a final review for inappropriate conclusions. 

Those constituents concluded to exceed background concentrations were carried to Step 3 of 

the COPC screening process. The detailed statistical evaluation is provided as 

Attachment 2. 

3.3 Step 3: Comparison to Screening Levels 

For each analyte carried to Step 3, the maximum detected concentration was compared to its 

human health risk-based screening levels identified below. Subsequently, for those 

chemicals (except lead) with maximum concentrations exceeding risk-based screening 

levels, the 95 percent upper confidence limit (95% UCL) on the mean concentration was 

compared to the human health risk-based screening levels identified below. In accordance 

with EPA guidance (EPA, 2005), the mean concentration of lead is used to represent an 

exposure area and was used in the comparison to screening levels: 

• Soil – EPA Region 6 Medium-Specific Screening Levels (MSSLs) issued December 2004, 

based on a target excess lifetime cancer risk (ELCR) of 1x10-6 and a non-cancer hazard 

index (HI) of 1. 

• Sediment – Sediment concentrations protective of fish consumption for those 

constituents with bioaccumulation potential, as identified in Table 3-1

(“Bioaccumulative COCs”) of the Ecological Risk Assessment Guidance document 

(TNRCC, 2001). The two-step process presented in the Texas Risk Reduction Program 

(TRRP) was used. 

005338
HUMAN HEALTH RISK ASSESSMENT VERSION 1.0 – STATE MARINE SUPERFUND SITE 

PROJ\USEPA\331756\TASK 7-RA\SM_HHRA_VERSION 1.0.DOC 4 

First, a risk-based exposure level (RBEL) for consumption of fish tissue was derived 

using equations presented in Table 5-3 of TCEQ’s regulatory guidance entitled 

Determining PCLs for Surface Water and Sediment (TCEQ, 2002). Fish tissue RBELs were 

based on a target ELCR of 1x10-5 and a HI of 1. With the exception of the fish ingestion 

rate, all exposure factors used in deriving the fish tissue RBEL were default factors 

presented in Table 5-3 of the aforementioned guidance. A fish ingestion rate of 0.026 

kg/day was used based on the 95th percentile of the average daily intake of marine 

finfish in the Gulf of Mexico, derived from fish surveys conducted by the National 

Marine Fisheries in 1993 (EPA, 1997). 

Second, biota-sediment accumulation factors (BSAFs) were obtained from the RI Report, 

supplemented with values from the open literature, and used to calculate the 

corresponding sediment screening level. The detailed calculations used to develop the 

sediment screening levels are presented in Attachment 3. 

Those chemicals evaluated in Step 3 that exceeded risk-based screening levels were 

identified as COPCs for the specific exposure area. In addition, sample quantitation limits 

(SQLs) were compared to screening levels for analytes that were always non-detected. 

Results of the COPC selection process, including the SQL comparison, are provided in 

Tables 2-1 through 2-8 of Attachment 1. 

In summary, the following COPCs were identified: 

• Soil - Former Wastewater Impoundment Area – benzo(a)pyrene, 

dibenzo(a,h)anthracene, and indeno(1,2,3-cd)pyrene; 

• Soil - Wastewater Treatment Facility – benzo(a)pyrene and iron; 

• Soil - Tar Burn Area – benzo(a)pyrene; 

• Soil - Current Aboveground Storage Tank Area – benzo(a)anthracene, benzo(a)pyrene, 

benzo(b)fluoranthene, and dibenzo(a,h)anthracene; 

• Soil - Maintenance Shed Area – benzo(a)pyrene, Aroclor-1254, dieldrin, p,p’-DDD, p,p’-

DDE, and p,p’-DDT; 

• Soil - Former Lauren Tank Farm Area – benzo(a)anthracene, benzo(a)pyrene, 

benzo(b)fluoranthene, dibenzo(a,h)anthracene, and alpha-chlordane; 

• Soil - Non-Source Area - benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene, 

dibenzo(a,h)anthracene, and heptachlor epoxide; and 

• Sediment – Aroclor-1242, copper, and zinc. 

3.4 Lead 

Based on mean concentration of lead not exceeding the 800 mg/kg commercial/industrial 

screening level for lead, the Adult Lead Model was not used to calculate lead risk at the site. 

There were a five hits above the screening level and two of the five hits are located near 

Hotspots number 2 and 3 in the Feasibility Study (FS), including the highest lead 

concentration of 4,090 mg/kg.

4. Exposure Pathways Quantified in the HHRA 

Various potential exposure pathways were quantified in the HHRA. Each soil “hot spot” 

area and the non-source area were evaluated separately. The following data groupings 

were used to estimate potential risks for the indicated receptors: 

• Current/Future Onsite Industrial/Commercial Worker #1 – Ingestion, dermal contact, 

and inhalation of COPCs at the former Wastewater Impoundment Area. 

• Current/Future Onsite Industrial/Commercial Worker #2 – Ingestion, dermal contact, 

and inhalation of COPCs at the former Wastewater Treatment Facility. 

• Current/Future Onsite Industrial/Commercial Worker #3 – Ingestion, dermal contact, 

and inhalation of COPCs at the former Tar Burn Area. 

• Current/Future Onsite Industrial/Commercial Worker #4 – Ingestion, dermal contact, 

and inhalation of COPCs at the Current Aboveground Storage Tank Area. 

• Current/Future Onsite Industrial/Commercial Worker #5 – Ingestion, dermal contact, 

and inhalation of COPCs at the former Maintenance Shed Area. 

• Current/Future Onsite Industrial/Commercial Worker #6 – Ingestion, dermal contact, 

and inhalation of COPCs at the former Lauren Tank Farm. 

• Current/Future Onsite Industrial/Commercial Worker #7 – Ingestion, dermal contact, 

and inhalation of COPCs in soil from the Non-source area. 

• Current/Future Onsite Trespasser – Not quantified since their exposure would be less 

than that of the industrial/commercial worker. 

• Current/Future Offsite Fisher – Ingestion of COPCs in fish from Lake Sabine by an 

adult; an exposure by a child was not quantified since a child would eat much smaller 

portions of fish, and at a lower frequency, than an adult. Therefore, the risk calculated 

for an adult can conservatively represent the risk to a child from eating fish. 

• Future Construction Worker – Not quantified since only two subsurface soil samples 

are available (which are combined with the surface soil data for the 

industrial/commercial worker) and their exposure would be less than that of the 

industrial/commercial worker. 

The 95% UCL on the mean concentration of each soil COPC was used as the exposure point 

concentration (EPC) unless it exceeded the maximum detected concentration for that data 

grouping. In sediment, the 95% UCL on the mean concentrations (or the maximum 

concentration, whichever was lower) was used to model the EPCs of sediment COPCs in 

fish. The 95% UCLs were calculated using the most recent version of ProUCL (Version 

3.00.02). The ProUCL output is provided in Attachment 4. The EPCs for each exposure area 

are provided in Tables 3.1 through 3.8 of Attachment 1. 

5. Exposure Factors 

A reasonable maximum exposure (RME) scenario was quantified for each of the indicated 

receptors. If the potential risks associated with an RME scenario exceeded acceptable risk 

levels, a central tendency (CT) scenario was also quantified. The exposure factors used in 

005340
HUMAN HEALTH RISK ASSESSMENT VERSION 1.0 – STATE MARINE SUPERFUND SITE 

PROJ\USEPA\331756\TASK 7-RA\SM_HHRA_VERSION 1.0.DOC 6 

the risk calculations are presented in Tables 4.1 through 4.3 of Attachment 1 and are 

summarized below: 

• Industrial/Commercial Worker – For each exposure parameter, the more conservative 

value between the standard default exposure factors presented in EPA guidance and the 

exposure factors used in TRRP. 

• Fisher - Standard default exposure factors presented in EPA guidance, with the 

exception of a fish ingestion rate of 0.026 kg/day, as presented in the Calcasieu Estuary 

Superfund Site study. 

For the CT exposure scenario, exposure factors were based on various EPA guidance 

documents, as indicated on Tables 4.1 through 4.3 of Attachment 1. 

6. Toxicity Assessment 

The following hierarchy of sources was used to obtain toxicity data for chemicals detected at 

the Site: 

• Integrated Risk Information System (IRIS) 

• Provisional Peer-Reviewed Toxicity Values (PPRTVs) 

• National Center for Environmental Assessment (NCEA) 

• Health Effects Assessment Summary Tables (HEAST) 

For those constituents without toxicity values, toxicity values for surrogate chemicals were 

used when available. Constituents with no appropriate toxicity values were evaluated 

qualitatively in the HHRA. Non-cancer toxicity values used in the HHRA are presented in 

Tables 5.1 and 5.2 of Attachment 1, while cancer toxicity values are provided in Tables 6.1 

and 6.2 of Attachment 1.

7. Risk Characterization 

Potential ELCRs and HIs were calculated using RME assumptions for the receptors and 

exposure pathways identified above (Tables 7.1 through 7.8 of Attachment 1, and

summarized in Tables 9.1 through 9.8 of Attachment 1). The following potential risks were 

identified: 

• Current/Future Onsite Industrial/Commercial Worker #1 – Ingestion, dermal contact, 

and inhalation exposures to soil COPCs in the former Wastewater Impoundment Area 

were quantified. An ELCR of 9x10-6 was calculated; an HI was not calculated due to the 

lack of non-cancer toxicity data for the COPCs. No COPCs exceeded an individual 

ELCR of 1x10-5. Therefore, risks are within acceptable levels and no COCs were 

identified for this receptor and exposure area. 

• Current/Future Onsite Industrial/Commercial Worker #2 – Ingestion, dermal contact, 

and inhalation exposures to soil COPCs in the former Wastewater Treatment Facility 

were quantified. An ELCR of 2x10-6 and HI of 0.6 were calculated. No COPCs exceeded 

an individual ELCR of 1x10-5 or HI of 1. Therefore, risks are within acceptable levels and 

no COCs were identified for this receptor and exposure area. 

005341
HUMAN HEALTH RISK ASSESSMENT VERSION 1.0 – STATE MARINE SUPERFUND SITE 

PROJ\USEPA\331756\TASK 7-RA\SM_HHRA_VERSION 1.0.DOC 7 

• Current/Future Onsite Industrial/Commercial Worker #3 – Ingestion, dermal contact, 

and inhalation exposures to soil COPCs in the former Tar Burn Area were quantified. 

An ELCR of 5x10-6 was calculated; an HI was not calculated due to the lack of noncancer toxicity data for the COPCs. No COPCs exceeded an individual ELCR of 1x10-5. 

Therefore, risks are within acceptable levels and no COCs were identified for this 

receptor and exposure area. 

• Current/Future Onsite Industrial/Commercial Worker #4 – Ingestion, dermal contact, 

and inhalation exposures to soil COPCs in the Current Aboveground Storage Tank Area 

were quantified. An ELCR of 2x10-5 was calculated; an HI was not calculated due to the 

lack of non-cancer toxicity data for the COPCs. No COPCs exceeded an individual 

ELCR of 1x10-5. Therefore, risks are within acceptable levels and no COCs were 

identified for this receptor and exposure area. 

• Current/Future Onsite Industrial/Commercial Worker #5 – Ingestion, dermal contact, 

and inhalation exposures to soil COPCs in the former Maintenance Shed Area were 

quantified. An ELCR of 2x10-4 and HI of 0.7 were calculated. One COPC (dieldrin) 

exceeded an individual ELCR of 1x10-5; no COPCs exceeded an individual HI of 1. 

Therefore, risks exceed acceptable levels and one COC (dieldrin) was identified for this 

receptor and exposure area (Table 10-1 of Attachment 1). 

Since a COC was identified, estimated risks were also evaluated using CT exposure 

assumptions. An ELCR of 2x10-5 and HI of 0.4 were calculated. Dieldrin exceeded an 

individual ELCR of 1x10-5 (Table 7.1 of Attachment 1). Therefore, risks exceed 

acceptable levels and one COC (dieldrin) was identified for this receptor and exposure 

area using CT exposure assumptions (Table 10-1 CTE of Attachment 1). 

• Current/Future Onsite Industrial/Commercial Worker #6 – Ingestion, dermal contact, 

and inhalation exposures to soil COPCs in the former Lauren Tank Farm Area were 

quantified. An ELCR of 2x10-5 and HI of 0.00005 were calculated. No COPCs exceeded 

an individual ELCR of 1x10-5 or HI of 1. Therefore, risks are within acceptable levels and 

no COCs were identified for this receptor and exposure area. 

• Current/Future Onsite Industrial/Commercial Worker #7 – Ingestion, dermal contact, 

and inhalation exposures to soil COPCs from all non-source areas were quantified. An 

ELCR of 9x10-5 and HI of 2 were calculated. One COPC (heptachlor epoxide) exceeded 

an individual ELCR of 1x10-5 and HI of 1. Therefore, risks exceed acceptable levels and 

one COC (heptachlor epoxide) was identified for this receptor and exposure area (Table 

10-2 of Attachment 1). 

Since a COC was identified, estimated risks were also evaluated using CT exposure 

assumptions. An ELCR of 1x10-5 and HI of 0.9 were calculated (Table 7.2 of Attachment 

1). No COPCs exceeded an individual ELCR of 1x10-5 or HI of 1. Therefore, risks are 

within acceptable levels and no COCs were identified for this receptor and exposure 

area using CT exposure assumptions. 

• Current/Future Offsite Fisher – Ingestion exposures to COPCs in sediment 

(bioaccumulated by fish in Lake Sabine) were quantified for an adult. An ELCR of 2x10-4

and HI of 7 were calculated. One COPC (Aroclor 1242) exceeded an individual ELCR of 

1x10-5 and copper and zinc exceeded an HI of 1. Therefore, risks exceed acceptable 

005342
HUMAN HEALTH RISK ASSESSMENT VERSION 1.0 – STATE MARINE SUPERFUND SITE 

PROJ\USEPA\331756\TASK 7-RA\SM_HHRA_VERSION 1.0.DOC 8 

levels and three COCs (Aroclor 1242, copper, and zinc) were identified for this receptor 

and exposure area (Table 10-3 of Attachment 1). 

Since COCs were identified, estimated risks were also evaluated using CT exposure 

assumptions. An ELCR of 8x10-5 and HI of 7 were calculated (Table 7.3 of Attachment 

1). One COPC (Aroclor 1242) exceeds an individual ELCR of 1x10-5 and two COCs 

(copper and zinc) exceed an HI of 1. Therefore, risks exceed acceptable levels and three 

whatCOCs (Aroclor 1242, copper, and zinc) were identified for this receptor and 

exposure area using CT exposure assumptions (Table 10-2 CTE of Attachment 1). 

8. Uncertainty Assessment 

The following discussion presents the major uncertainties associated with this HHRA. 

8.1 Data Issues 

SQLs for some analytes in soil and sediment samples exceeded screening levels 

(Attachment 6). However, these chemicals are not expected to be site-related and therefore 

exert no significant impact on the HHRA or its conclusions. 

There is some uncertainty associated with the historical data collected in 1995 in terms of the 

exact locations where these samples were collected. However, the data were used since it 

represents soil/sediment quality onsite and adjacent to the Site. Use of this data is not 

expected to affect the conclusions of the HHRA, but adds uncertainty to the locations that 

may warrant risk management. 

8.2 Pesticides in Soil 

Dieldrin and heptachlor epoxide were identified as COCs in soil. Based on knowledge of 

historical site operations, these chemicals are not expected to be associated with site 

activities. However, background concentrations were not available for comparison. 

Therefore, there is uncertainty in the risk estimates by inclusion of these chemicals. 

8.3 Aroclor 1242 in Sediment 

Aroclor 1242 is a risk driver for sediment in the HHRA. However, there is much 

uncertainty in the risk calculations, primarily due to the available dataset. 

No source has been identified onsite. Available data from all areas of the Site indicate no 

detections of Aroclor 1242, as expected based on knowledge of site activities. The number of 

samples analyzed for Aroclor 1242 in each area is indicated below: 

• Wastewater Impoundment - No detects for all Aroclors in four soil samples. 

• Wastewater Treatment Facility - No detects for all Aroclors in two soil samples. 

• Tar Burn Area – PCBs were not evaluated. 

• Current AST Area – PCBs were not evaluated. 

• Maintenance Shed Area – One detect of Aroclor 1254 in six samples; all other Aroclors 

were non-detect. 

• Lauren Tank Farm – Two detects of Aroclor 1248 in six samples; all other Aroclors were 

non-detect.

• Non-source Area – No detects for all Aroclors in two soil samples. 

Aroclor 1242 was detected in one of seven sediment samples; it was the only Aroclor 

detected. PCBs were not analyzed in the background sediment dataset. The fish ingestion 

risk calculations are based on a single detected PCB concentration in sediments. This 

concentration is not expected to represent the PCB concentrations that a fish contacts during 

its lifetime before it is caught and eaten since a fish’s home range is much larger than the 

single location. Therefore, using one location to model fish uptake is extremely 

conservative. 

The TDH prepared a risk assessment of Sabine Lake under EPA’s Near Coastal Water Grant 

(TDH, 1995). Although these data were gathered for a broader study, the data were 

reportedly collected in accordance with EPA’s Guidance for Assessing Chemical Contaminant 

Data for Use in Fish Advisories, Fish Sampling and Analysis (EPA, 1993) and analyses were 

performed in the TDH laboratory using EPA-approved methods for detection of metals, 

pesticides, PCBs, semivolatile, and volatile organic constituents. Aquatic species were 

collected to represent commonly consumed edible tissue taken by the public from sample 

locations in Sabine Lake (South), Sabine Lake (North), and Sabine Pass. The analytical data 

from this investigation are presented in the table below. As shown, Aroclor 1242 was not 

detected in fish samples. 

8.4 Copper in Sediment 

Copper is a risk driver for sediment in the HHRA. However, there is much uncertainty in 

the risk calculations, primarily due to the available dataset. 

005344
HUMAN HEALTH RISK ASSESSMENT VERSION 1.0 – STATE MARINE SUPERFUND SITE 

PROJ\USEPA\331756\TASK 7-RA\SM_HHRA_VERSION 1.0.DOC 10 

No significant source of copper has been identified onsite. Results of the statistical 

comparison to background indicate the following: 

• Former Wastewater Impoundments – exceeds background; maximum detection of 298 

ppm. 

• Former Wastewater Treatment Facility – exceeds background; maximum detection of 

299 ppm. 

• Tar Burn Area – exceeds background; maximum detection of 155 ppm. 

• Current AST Area – within background. 

• Maintenance Shed Area – within background. 

• Lauren Tank Farm – exceeds background; maximum detection of 7,390 ppm (remaining 

results <100 ppm). 

• Non-source Area – exceeds background; maximum detection of 5,480 ppm (only six 

results above 200 ppm). 

As expected (since copper is a naturally occurring element), copper was detected in 61 of 62 

sediment samples. Copper was not analyzed in the background sediment dataset. The fish 

ingestion risk calculations are based on a 95% UCL concentration based on the 62 samples. 

Only five locations exceeded risk-based concentrations. 

The calculated HI is 2 using both reasonable maximum exposure and central tendency 

exposure scenarios. This level is only slightly higher than the acceptable HI of 1.

The TDH prepared a risk assessment of Sabine Lake under EPA’s Near Coastal Water Grant 

(TDH, 1995). Although these data were gathered for a broader study, the data were 

reportedly collected in accordance with EPA’s Guidance for Assessing Chemical Contaminant 

Data for Use in Fish Advisories, Fish Sampling and Analysis (EPA, 1993) and analyses were

collected to represent commonly consumed edible tissue taken by the public from sample 

locations in Sabine Lake (South), Sabine Lake (North), and Sabine Pass. A summary of the 

inorganic data from this investigation is presented in the table below. As shown, copper 

was detected in 3 of the 10 fish samples. The maximum detected concentration of copper in 

fish tissue (19 ppm) is much lower than the modeled fish tissue concentration (150 ppm) 

used in the risk calculations for the State Marine Site.

8.5 Zinc in Sediment 

Zinc is a risk driver for sediment in the HHRA. However, there is much uncertainty in the 

risk calculations due to the following reasons. 

No significant source of zinc has been identified onsite. Results of the statistical comparison 

to background indicate the following: 

• Former Wastewater Impoundments – exceeds background; maximum detection of 460 

ppm. 

• Former Wastewater Treatment Facility – exceeds background; maximum detection of 

908 ppm; other concentrations <400 ppm. 

• Tar Burn Area – exceeds background; maximum detection of 424 ppm. 

• Current AST Area – within background. 

• Maintenance Shed Area – exceeds background; maximum detection of 2,220 ppm. (other 

concentrations <400 ppm). 

• Lauren Tank Farm – exceeds background; maximum detection of 1,480 ppm (other 

concentrations <300 ppm). 

• Non-source Area – exceeds background; maximum detection of 38,700 ppm (five results 

above 1,000 ppm). 

As expected (since zinc is a naturally occurring element), zinc was detected in all 66 

sediment samples. Zinc was analyzed in the background sediment dataset and was 

concluded to exceed background. The fish ingestion risk calculations are based on a 95% 

UCL concentration based on the 66 samples. Only two sediment locations exceeded riskbased concentrations for zinc. 

The calculated HI is 5 using both reasonable maximum exposure and central tendency 

exposure scenarios. This level is slightly higher than the acceptable HI of 1.

The TDH prepared a risk assessment of Sabine Lake under EPA’s Near Coastal Water Grant 

(TDH, 1995). Although these data were gathered for a broader study, the data were 

reportedly collected in accordance with EPA’s Guidance for Assessing Chemical Contaminant 

Data for Use in Fish Advisories, Fish Sampling and Analysis (EPA, 1993) and analyses were

collected to represent commonly consumed edible tissue taken by the public from sample 

locations in Sabine Lake (South), Sabine Lake (North), and Sabine Pass. A summary of the 

inorganic data from this investigation is presented in the table above. As expected, zinc was 

detected in all 10 fish tissue samples. The maximum detected concentration of zinc in fish 

tissue (344 ppm) is much lower than the modeled fish tissue concentration (4,300 ppm) used 

in the conservative risk calculations for the State Marine Site. 

9. Preliminary Remediation Goals 

Preliminary Remediation Goals (PRGs) were developed for COPCs and exposure areas 

where the total risk for a receptor exceeded 1x10-5 or an HI of 1. The target risk levels used 

to develop the PRGs were an ELCR equal to 1x10-5 and an HI of 1. The same exposure factor 

values used in the exposure assessment were used to calculate PRGs. Attachment 5

contains the PRGs described below: 

• Maintenance Shed Area – A PRG was identified for protection of ingestion, dermal 

contact, and inhalation exposures to dieldrin in soil by current and future 

industrial/commercial workers. The PRG of 1.2 mg/kg is based on a 1x10-5 ELCR for 

this receptor. Detected concentrations in two samples collected from this area exceed 

the PRG (Figure 1). 

• Non-Source Areas – A PRG was identified for protection of ingestion, dermal contact, 

and inhalation exposures to heptachlor epoxide in soil by current and future 

industrial/commercial workers. The PRG of 2.1 mg/kg is based on a 1x10-5 ELCR and 

HI less than 1 for this receptor. The detected concentration in one sample collected from 

this area exceeds the PRG (Figure 2). 

• Sediments in Lake Sabine – A PRG was identified for protection of exposures to 

Aroclor 1242, copper, and zinc in edible fish tissue by current and future receptors 

eating fish caught in Lake Sabine. The PRG of 1.5x10-4 mg/kg for Aroclor 1242 is based 

on a 1x10-5 ELCR for this receptor. The detected concentration of Aroclor 1242 in one 

sample (SE-9) collected from sediment exceeds the PRG (Figure 3). The PRGs of 91 and 

734 mg/kg for copper and zinc, respectively, are based on a HI of 1 for this receptor. 

The detected concentrations in four and two locations, respectively, exceed the PRGs for 

copper and zinc (Figures 4 and 5).

(1) Maximum detected concentration is used for screening. Those chemicals whose maximum detected concentrations exceeding Screening Levels, UCL 95% was used for screening. ARAR/TBC = Applicable or Relevant and Appropriate Requirement/To 

(2) These background values were calculated from a small data set and are not recommended for definitive comparisons. COPC = Chemical of Potential Concern(3) Calculated for bioaccumulative chemicals in sediment according to methodology presented in the text. C = Screening level is based on a carcinogenic endpoint.

max = Screening level is based on a ceiling limit.

(4) Rationale Codes Selection Reason: Above Screening Levels (ASL) mg/kg = Milligrams per kilogram

Deletion Reason: Below Screening Level (BSL) NA = Not available

Not Detected (ND) N = Screening level is based on a noncarcinogenic endpoint.Not bioaccumulative according to TRRP (Not Bio) sat = Screening level is based on soil saturation.

Qualifiers:B = Metals - Result is estimated, reported concentration is between M

Organics - Analyte was detected in the associated method blank, 

J = Estimated value.Q = Severe QC or quantitation problem - no result reported but analytH = Result is likely biased high K = Result is estimated but bias is unknownL = Reported concentration is < CRQL (contract-required quantitation * = Result not recommended for use due to associated QA/QC perform

005441
A statistical comparison of site data to historic background data was performed to 

identify potentially site-related constituents that were detected at the State Marine 

Superfund Site. Results of the comparison were used to identify chemicals of potential 

concern in the human health risk assessment and ecological risk assessment. Results of 

the evaluation are described below. 

Introduction 

Background data were available for both soil and sediment for the State Marine Site. 

These included five soil and five sediment samples. The background data are 

summarized in Table 1. Both inorganic and organic parameter concentrations were 

available, with the organic data having a higher percentage of nondetects, as is typical. 

With this few samples, and the typically higher frequency of nondetects, decisions with 

background comparisons with the organic data are not recommended. However, 

statistics were carried out and reported for all parameters that were detected in both Site 

and background populations. 

This statistical analysis primarily focused on comparisons of central tendency using the 

nonparametric Wilcoxon Rank Sum test. These comparisons were reinforced with 

graphical comparisons of the background and Site data via box and whisker plots. The 

comparison results with inorganics were used in consideration of which parameters 

would be included in risk calculations. Background threshold values were also 

calculated, as discussed later, but their use is not recommended for definitive decisions 

(with inorganic or organic data) since estimates of the upper tail of the background 

population carry considerable uncertainty with only five background samples. 

Wilcoxon Rank Sum Comparisons 

The Wilcoxon Rank Sum (WRS) test is a nonparametric test used for determining 

whether a difference exists between two populations. It can be used to test whether 

measurements from one population (such as the Site population) tend to be shifted 

higher than those from another population (such as the background population). 

Acknowledged as a nonparametric test, it is suggested by EPA background guidance for 

cases when the sample size is less than 20 (EPA, 2002). As a nonparametric test based on 

ranks of the data, it is less influenced by spurious results in either data set than 

parametric tests, such as a t-test performed on the concentrations, which makes a 

distributional assumption about the data. 

This test calculates the probability that the observed differences between the two 

populations are due merely to random variability in the data, as opposed to being due to 

an actual elevated shift in one. If this probability is less than a chosen significance level, 

in this case 0.20, then the decision is made that a significant difference does exist 

between the two populations. A significance level of 0.20 implies that one has 80% 

confidence ([1 – 0. 20]*100%) that the two groups will be determined to be statistically 

equivalent when they actually are. 

005442
With a background data set of only five samples (five for soil and five for sediment) 

there is still considerable uncertainty in these background comparisons, but 

complemented with the box and whisker plots presented in Figures 1, 2, and 3, a useful 

understanding of how the background and Site populations compare can be obtained. 

Figure 1 presents plots for inorganics in soil, while Figure 2 presents plots for organics 

in soil. Plots of sediment data appear in Figure 3. Box and whisker plots are explained 

in the following section. 

The results of these comparisons are presented in Tables 2 through 14 for each matrixSite combination. While each table needs to be reviewed individually, four soil metals 

are seen to be most likely to exceed background. These are copper, lead, silver, and zinc. 

Occasionally, these were not seen to exceed background and occasionally other soil 

metals were. For sediment, all metals except for antimony were found to significantly 

exceed background. 

Box and Whisker Plots 

Box and whisker plots are often very good at demonstrating how much overlap exists 

between two or more populations. These plots simultaneously present information on 

the central tendency, variability, and skewness for a sample data set by sketching the 

center 50 percent of the concentrations with a box, and then illustrating the typical tail 

regions of the distribution with whiskers (see EPA, 2000 for methodology and 

examples). For atypical concentrations that extend further from the center than the 

whiskers, individual data symbols are plotted. These plots often provide a better visual 

perspective on the comparison between populations than scatter plots, particularly 

when a large number of data points cause individual scatter plot symbols to overlap. 

Specifically, these box and whisker plots are constructed as follows: 

• The height of the box represents the interquartile range (IQR). The IQR is the 

distance between the 25th and the 75th percentiles. 

• The horizontal line in the box interior represents the median. 

• The vertical lines issuing from the box extend to the minimum and maximum 

measured values (as long as these minimum and maximum values do not extend 

further from the box than a distance of 1.5 times the IQR). 

• Individual data symbols are used for concentrations that exceed the whiskers. 

These principles are seen in the example box and whisker plots shown in Figure 4. The 

upper and lower edges of the box and the ends of the whiskers all represent actual 

measured concentrations in the sample data set. Specifically, for Data Group C, the 25th 

percentile, 75th percentile, and median are all labeled as part of the box. In this plot the 

overall minimum value serves as the end of the whisker since it is within a distance of 

1.5 x IQR from the box. The maximum values (and the next to the largest value), 

however, are further from the box than a distance of 1.5 × IQR. Thus, they are labeled as 

outliers. The third largest overall value, that represents the largest value within a 

distance of 1.5 risk based concentration IQR, serves as the end of the upper whisker. 

005443
Various interpretations are possible by examining these box and whisker plots. For 

example, if extensive overlap exists between the box plots from different data groups, 

such as between data groups B and C, then the measurements from each group, on 

average, are very similar. Conversely, little overlap, as seen between data group A and 

the other two, suggests that the measurements from the groups are, on average, quite 

different. The box and whisker plots presented in Figures 1 through 3 offer a similar 

opportunity to visualize the comparisons between Site and background concentrations 

for inorganic soil, organic soil, and inorganic sediment, respectively.

Comparisons to a Background Threshold Value 

A common feature in comparisons to background involves the calculation of a 

background threshold value to which individual Site concentrations are compared. 

There are various threshold values that can be calculated and three are included here. 

These are the upper tolerance limit (UTL), the upper prediction limit (UPL), and the 

maximum of background sample concentrations. Although these are presented in 

Table 1, none of them were used definitively in determining whether a site should be 

considered to exceed background (the WRS test was used for this). The size of the 

background data set (5 samples) makes it difficult to estimate an appropriate elevated 

background value. Instead, they are presented as auxiliary information, particularly for 

those accustomed to considering these thresholds. 

005444
The UTL was calculated as a 95 percent/95 percent background UTL, that is, an upper 

bound (with 95 percent confidence) of the background 95th percentile. The calculation 

of UTLs depends on a distributional assumption. Given that the sample size (5 samples) 

did not lend itself to a good understanding of the distribution, all UTLs were calculated 

assuming normality. Some environmental data sets, including background, 

demonstrate more skewness than a normal distribution (positive skewness), but 

assuming normality tends to offer a lower calculated upper bound than if an attempt is 

made to adjust for skewness, such as with a log transformation. Thus, the assumption 

of normality tended to offer values conservative for the environment. 

Furthermore, the Shapiro-Wilk test for normality was performed on each parameter (see 

Table 1) with the results suggesting that normality was a typically good assumption 

(only a few p-values less than 0.05, the recommended threshold for this test of 

normality) although with only five samples one would typically not expect there to be 

sufficient evidence to reject normality (unless strong deviations from a normal 

distribution were indicated). The normal UTLs were calculated using the following 

equation: 

( ) ×+= sKxUTL , 

where x is the sample mean; 

K is the tolerance factor; and 

s is the sample standard deviation. 

Since UTLs are an estimate of the 95th percentile of the background population, one 

understands that (with 95% confidence) as many as 5% of results equivalent to 

background may exceed this threshold. 

Included in Tables 2 through 14 are the number of exceedances of the UTL as well as the 

percentage of exceedances. Assuming the background populations for which the UTLs 

were calculated were normally distributed, one would expect this percentage to exceed 

5% only about 5% of the time (1 in 20) if the upper tails of the Site and background 

populations are equivalent. Of course, considerable uncertainty exists given the 

background sample size, so this comparison was not relied upon, even though it is 

reported. 

Some consideration to using UPLs as a background threshold value has been voiced in 

the environmental community. It is an upper confidence limit on the next encountered 

Site result. The UPLs were also calculated with a confidence level of 95% and an 

assumption of normality as follows: 

n n stxUPL 1 1 −1,95.0 +××+= , 

where x is the sample mean; 

t is the Student’s t statistic; 

n is the number of background samples; and 

s is the sample standard deviation. 

005445
Adjustments to the equation are possible to expand the limit to include some future 

number of multiple results, but this is not typical of those proposing UPLs as a 

background threshold value. Because the UPL focuses on the next encountered result, it 

sometimes results in a large number of exceedances (of the UPL) when the number of 

Site results to be compared is large (even more so than the UTL). Being closer to the 

mean, it is often considered a more stable value than the UTL, but it also results in more 

exceedances by results equivalent to those in the background population (false 

indications of individual exceedances over background). 

The number of exceedances are provided in Tables 2 through 14. Also include are the 

number of exceedances of the background sample maximum. The number of UPL 

exceedances are more than the number of exceedances of the UTL which is to be 

expected since it tends to estimate a lower percentile than the UTL. Even more 

exceedances are noted with the background sample maximum. The background sample 

maximum also estimates a value less than the 95th percentile with small data sets. (It 

would not estimate the 95th percentile, with 95% confidence, unless about 60 background 

samples were available.) 

As would be expected, the number of exceedances of these background threshold values 

increases when the Site population appears to exceed the background population (as 

indicated by the WRS test). With a small number of background samples, however, 

estimating an upper percentile of the background population carries a lot of uncertainty, 

and reliance on these values is not recommended.
