# 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 consiste nt with the EPA-approved Human Health

Risk Assessment Work Plan for the Site (CH2 MHILL, 2005). In accordance with the Work

Plan, a statistical comparison of onsite concen trations 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 we re 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 fe w locations on-site, are not expected to be

associated with site activiti es, but background concentrat ions were not available for

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

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

tissue concentrations used in this HHRA ar e 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 availa ble to CH2M HILL electronically as of June

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

in 1995 and 2001 from various areas, includin g 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 hist orical activities performed in six distinct

areas. The data were grouped for the HHR A 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 se mi-volatile organic compounds, and no

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

# 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 we re used to model edible fish tissue

concentrations.

• **Fish** – Historical edible fish ti ssue 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 remo te 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 Si te. 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 cu rrent 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 Co ncern 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, ma gnesium, 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

# 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 freq uency 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 concen trations 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 th is study while the conclusions

from the Wilcoxon Rank Sum ar e used for risk decisions.

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

background dataset underwent a final re view 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 maximu m detected concentration was compared to its

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

chemicals (except lead) with maximum concen trations exceeding ri sk-based screening

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

compared to the human health ri sk-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 Screenin g 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 bioaccumulatio n potential, as identified in **Table 3-1**

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

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

(TRRP) was used.

# 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. Th e detailed calculations used to develop the

sediment screening levels are presented in **Attachment 3**

.

Those chemicals evaluated in Step 3 that ex ceeded 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 St orage Tank Area – benzo(a)anthracene, benzo(a)pyrene,

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

• Soil - Maintenance Shed Area – benzo(a)pyren e, 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)a nthracene, and alpha-chlordane;

• Soil - Non-Source Area - benzo(a)anthracen e, 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 ex ceeding 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 leve l and two of the five hits are located near

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

concentration of 4,090 mg/kg.

PROJ\USEPA\331756\TASK 7-RA\SM_HHRA_VERSION 1.0.DOC 5 

# 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 evaluate d 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 form er 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 Curre nt 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 quant ified 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 ex posure 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 th e 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 wi th an RME scenario exceeded acceptable risk

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

# 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 fa ctors 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 toxici ty 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 th is receptor and exposure area.

# 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 leve ls 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 th e 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 calcul ated. 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 th e 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 th is 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 (Aro clor 1242) exceeded an individual ELCR of

1x10 -5 

# and copper and zinc exceeded an HI of 1. Therefore, risks exceed acceptable

# 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) ex ceeds an individual ELCR of 1x10 -5 

# and two COCs

(copper and zinc) exceed an HI of 1. Therefor e, 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 expe cted to be site-related and therefore

exert no significant impact on the HHRA or its conclusions.

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

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

represents soil/sediment quality onsite and adjace nt 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, th ese chemicals are not expected to be associated with site

activities. However, backgr ound 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, prim arily due to the available dataset.

No source has been identified onsite. Availabl e 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 fo r all Aroclors in four soil samples.

• Wastewater Treatment Facility - No detect s 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 Aroclo r 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-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 PC B 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 gath ered 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 edib le 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 du e to the available dataset.

# 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 iden tified onsite. Results of the statistical

comparison to background indicate the following:

• Former Wastewater Impoundments – exceed s background; maximum detection of 298

ppm.

• Former Wastewater Treatment Facility – ex ceeds 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; ma ximum detection of 7,390 ppm (remaining

results <100 ppm).

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

results above 200 ppm).

As expected (since copper is a naturally occurr ing 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 s lightly higher than the acceptable HI of 1.

inorganic data from this investigation is pres ented 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 – exceed s background; maximum detection of 460

ppm.

• Former Wastewater Treatment Facility – ex ceeds 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; maxi mum detection of 38,700 ppm (five results

above 1,000 ppm).

As expected (since zinc is a naturally occu rring 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 in gestion 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 slig htly higher than the acceptable HI of 1.

# 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 di eldrin 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 fi sh 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** ).

# HUMAN HEALTH RISK ASSESSMENT – STATE MARINE SUPERFUND SITE

PROJ\USEPA\331756\TASK 7-RA\DRAFT HHRA\TECH MEMO.DOC JULY 2005 

# (This page intentionally left blank.)

# 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 we re used to identify chemicals of potential

concern in the human health risk assessment an d ecological risk assessment. Results of

the evaluation are described below.

**Introduction**

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

These included five soil and five sedime nt 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 nondet ects, decisions with

background comparisons with the organi c 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 us ed 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 uncertaint y 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 popula tions. 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 perf ormed on the concentrations, which makes a

distributional assump tion about the data.

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

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

an actual elevated shift in one. If this prob ability 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 gr oups will be determined to be statistically

equivalent when they actually are.

# With a background data set of only five sa mples (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 Si te 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 backgrou nd. These are copper, lead, silver, and zinc.

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

metals were. For sediment, all metals exce pt 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 th at 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 popu lations than scatter pl ots, particularly

when a large number of data points cause in dividual 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 bo x 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 co ncentrations that exceed the whiskers.

These principles are seen in the ex ample box and whisker plots shown in **Figure 4** . The

upper and lower edges of the box and the en ds 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 labe led as part of the box. In this plot the

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

1.5 x IQR from the box. The maximum valu es (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.

# Various interpretations are possible by ex amining 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 be tween 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 indivi dual 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 concentratio ns. 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 te st was used for this). The size of the

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

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

those accustomed to considering these thresholds.

# The UTL was calculated as a 95 percent/95 pe rcent background UTL, that is, an upper

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

of UTLs depends on a distributi onal 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 environmen tal data sets, including background,

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

assuming normality tends to offer a lower ca lculated 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 norm ality 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 (u nless 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 95 th 

# 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 bac kground 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 stxUPL

# 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 exc eedances (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 th ose in the background population (false

indications of individual ex ceedances 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 th e 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 95 th 

# percentile with small data sets. (It

would not estimate the 95 th 

# percentile, with 95% confidence, unless about 60 background

samples were available.)

As would be expected, the number of exceed ances 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 backgrou nd population carries a lot of uncertainty,

and reliance on these values is not recommended.
