Executive Summary

The ROD, signed in August 1993 provided for a limited action remedy for the Soldier Creek Sediment and Surface Water Operable Unit 2. The remedial actions selected in the ROD incorporate the following: 1) a five-year monitoring program ofthe Soldier Creek sediment and surface water at on-base and off-base locations to detennine if contaminant migration has occurred and, if so, determine if migration has resulted in contaminant concentrations greater than health based cleanup goals, 2) an ecological investigation of Soldier Creek sediment and surface water to further define potential environmental risk, 3) annual monitoring reports to present and evaluate monitoring results for levels exceeding health-based cleanup goals and, finally 4) a five-year ROD review to ensure that the remedy confinues to provide adequate protection of human health and the environment or whether additional remedial actions are necessary. The trigger for this second five-year review was the first five year review which was completed in 1998 and gained regulatory acceptance in October 2002.

The assessment of this review indicates that there is no longer danger posed to human health and the environment. Numerous remedial activities not required by the ROD have occurred in the area that serve to remove or reduce potential contaminant sources. In addition, results ofthe human health risk assessments indicate no unacceptable risk to human health. Because there have been no exceedences of health based screening levels (based on 10 ̂ ) in the sampling over the past five years, it is recommended that sampling be discontinued and the site be considered closed in accordance with the ROD. After gaining regulatory acceptance of this Five-Year Review, Tinker AFB will request de-listing ofthe OU.

SECTION 1 INTRODUCTION

The U.S. Air Force has conducted a five-year review ofthe remedial action implemented at the Soldier Creek site at Tinker Air Force Base in Oklahoma (Figure 1). The primary purpose of the review is to determine whether the remedy remains protective of human health and the environment. Five-year review reports identify deficiencies, if any, and recommendations to address them. Five-year review reports document the evaluation of the implementation of the remedy and operation and maintenance (O&M), as well as the continued appropriateness of remedial action objectives (RAOs), including cleanup levels at a site. This is the second five-year review for the Soldier Creek site. The previous Five-Year Review, submitted September 1998, gained regulatory approval through a letter from the USEPA dated 10/22/2002.

This review is required by statute. Section 121(c) of the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA), as amended by the Superfiind Amendments and Reauthorization Act of 1986 (SARA), and Section 300.430(f)(4)(ii) of the National Oil and Hazardous Substance Pollution Contingency Plan (NCP), require that periodic (no less often than every five years) reviews be conducted for sites where hazardous substances, pollutants, or contaminants remain at the site above levels that allow for unlimited use and unrestricted exposure following the completion of all remedial actions.

Executive Order 12580 delegates the authority to conduct five-year reviews to the Departments of Defense and Energy, where either the release is on, or the sole source of the release is from, any facility under the jurisdiction of those departments. In the Federal Facilities Agreement signed on December 9, 1988 between the U.S. Air Force, EPA, and the Oklahoma State Department of Health (succeeded by the Oklahoma Department of Environmental Quality in 1993), the U.S. Air Force was established as the lead agency for remediating the Soldier Creek Site.

SECTION 2 BACKGROUND

SITE DESCRIPTION

The main portion of Soldier Creek is to the east of Tinker AFB; however, two unnamed tributaries (East and West Soldier Creeks) originate on the Base. Soldier Creek flows to the

north from its headwaters near Southeast 59* Street to its confluence with Crutcho Creek approximately six miles downstream (Figure 2). According to the Federal Facility Agreement (FFA) for the Base, the Soldier Creek Operable Unit includes Soldier Creek, its tributaries, and any area underlying or adjacent to the waterway that may be contaminated by the migration of hazardous substances, pollutants, or contaminants from Tinker AFB.

The Soldier Creek Sediment and Surface Water (SCSSW) site, or Operable Unit 2 (OU-2), includes Soldier Creek, its tributaries, and any area underlying or adjacent to the waterway that may be contaminated by the migration of hazardous substances or pollutants from Tinker AFB. The tributaries of Soldier Creek are unnamed, but are referred to as East and West Soldier Creeks in this report. As required in the SCSSW ROD, a work plan was created for monitoring this OU and the boundaries of the OU were established in the work plan. As defined in the work plan (WCFS, 1994), these boundaries are as follows: 1) All sediment and surface water of East Soldier Creek that originate on Tinker AFB to the intersection of East Soldier Creek and Interstate 40 north of Tinker AFB, and 2) All sediment and surface water of West Soldier Creek that originate on Tinker AFB to the intersection of West Soldier Creek and Interstate 40 north of Tinker AFB.

The boundaries include the ditches leading from the eight NPDES outfalls to Eiast and West Soldier Creeks, the lower portion of the stream defined as Tributary B in the Rl/FS documents (just prior to its confluence with East Soldier Creek), and terrestrial habitats within the 100-year floodplain of the aforementioned stream segments (or within 50 feet from either bank of the sfream where it is not located in the 100-year floodplain). These boundaries supercede the boundaries originally established in the Soldier Creek RI (B&V, 1993b).

Environmentally sensitive areas within the Soldier Creek site include the Garber-Wellington aquifer and Soldier Creek as described above. The closest Superfimd site is the Mosley Road Landfill site located approximately 6 miles north of Tinker AFB.

LAND AND RESOURCE USE

Prior to 1941, the site was located on undeveloped pasture and prairie lands. There were some agricultural activities and ranching but no known industrial uses prior to 1941. Beginning in 1941, 960 acres ofland were donated to the Army Air Corps by the City of Oklahoma City for the construction ofthe Midwest Air Depot. Renamed Tinker Field in 1942 and subsequently Tinker Air Force Base in 1948, the entire base now covers 5,277 acres.

The on-base portion of the Soldier Creek site is in the northeast quadrant of Tinker AFB, which is the most industrialized area ofthe base.

The off-base properties within the Soldier Creek site include the Kimsey Addition to the north, along with commercial/retail establishments and mobile homes to the east. The Kimsey Addition is a residential area consisting of approximately 100 homes bounded by Tinker AFB to the south and west. Interstate 40 to the north, and Douglas Boulevard to the east. The commercial/retail facilities between Tinker AFB and East Soldier Creek include convenience stores and self-storage units. Other than the Evergreen Mobile Home Park, the remainder of the site east of Douglas Boulevard and northwest of East Soldier Creek is undeveloped between the

mobile home park and Interstate 40.

Soldier Creek and its tributaries receive surface runoff from approximately 9,000 acres (14 square miles), at its confluence with Crutcho Creek. Areas of Tinker AFB that contribute runoff or discharge to Soldier Creek and its tributaries include the eastern-most runway areas and the Building 3001 complex. Prior to April 1996, the IWTP discharged treated water to East Soldier Creek. Recharge from East Soldier Creek to the aquifer occurs and remains within the boundaries of Tinker AFB.

Surrounding Community

The Soldier Creek site and Tinker AFB lie within an area representing transition from residential and industrial/commercial land use on the north and west to agricultural land use to the east and south. Soldier Creek and its tributaries, which flow northwest through the area, are bordered by recreational and residential areas with some areas supporting commercial and industrial land use. Some off-base industries, such as a metal plating facility and a dry cleaning facility, and commercial facilities such as gas stations, auto repair facilities, and a closed sanitary landfill are located within the drainage basin. In addition, three schools. Soldier Creek Elementary, Steed Elementary, and Monroney Junior High are located within the drainage basin. There are ten public parks within the general vicinity of Tinker AFB, including the Joe B. Bams, Fred F. Meyers, Kiwanis, and Lions Parks. A public golf course is also located north ofthe base. Five trailer parks are located north and northeast of Tinker AFB.

The land use plan for the area immediately north of Tinker AFB, between Sooner Road and Douglas Boulevard includes all levels of land use. The areas between Sooner Road and Midwest Boulevard (see Figure 1 for location) are zoned primarily for housing (single and multifamily imits) and low to medium commercial use. The area between Midwest Boulevard and Douglas Boulevard is zoned primarily for heavy commercial and moderate to heavy industrial use.

Soldier Creek, which flows from Tinker AFB into adjacent neighborhoods, is reportedly used for wading and playing by area children and is large enough to support edible fish. No hunting or fishing has been reported to occur in the immediate area outside of Tinker AFB. Hunting is not permitted on base and fishing is not permitted in Soldier Creek within base boundaries. Beneficial uses of Soldier Creek include agriculture, secondary recreation, process and cooling water, and aesthetics. Soldier Creek also supports a warm-water aquatic community.

Human Use of Resources

The most important source of potable groundwater in the Oklahoma City metropolitan area is the Central Oklahoma aquifer, which is commonly referred to as the "Garber-Wellington aquifer." Tinker AFB presently obtains part of its water supplies from wells that are completed in the Garber-Wellington aquifer. Base wells range from 700 to 1,100 feet in total depth, with yields ranging from 205 to 250 gallons per minute (gpm).

On the east side of Tinker AFB, the Garber-Wellington aquifer has been classified as a Class IIA aquifer by the State of Oklahoma, indicating that it provides groundwater from a major, unconfined basin that is capable of being used as a drinking water supply with little or no freatment (OAC 785:45-7-3). The westem portion ofthe Garber-Wellington aquifer basin, which extends from the west side of the base to just west of Oklahoma County, is classified as a Class IIC aquifer, a major confined groundwater basin. Tinker AFB and the nearby communities of Midwest City and Del City derive a portion of their water supply from the Garber-Wellington aquifer.

Until 1993, groundwater was used as a domestic water source by several ofthe residents living within and adjacent to the boundaries ofthe site. Most of these wells were removed from service in 1994 after municipal water distribution lines were conveyed to and installed at the residences and businesses. There are no off-base wells adjacent to the northeast portion of the base that are known to be used for drinking water purposes. All of the water supply wells on Tinker AFB are routinely sampled for contaminants.

CONTAMINANTS

The Air Force Installation Restoration Program (IRP) Phase I identified potential sources of contamination through records searches and reviews of waste management practices. The first report of a release to the environment occurred in 1983 during routine wellhead sampling and testing. Trichloroethene (TCE) and tetrachloroethene (PCE) were detected in two of the base water supply wells (WS 18 and WS 19) at Building 3001. A Phase II IRP investigation was conducted in 1984 to confirm and quantify contamination resulting from past waste storage practices at Building 3001. Sampling was also initiated at East and West Soldier Creek in 1984. Sample results indicated the presence of chromium and solvent contamination in the.sediment and surface water. In Septerriber 1987, the Soldier Creek site was evaluated under the hazard ranking system with a score of 42.24 and was placed on the NPL.

The groundwater used by residents and the work force of Tinker AFB was identified as an exposure pathway. Potential points of exposure included water supply wells and discharge to surface water bodies. Exposure with long-term health effects was deemed a possibility in the 1988 baseline risk assessment. A chronology leading to the NPL listing is provided in Table 1.

Remedial investigations ofthe SCSSW OU were conducted between 1990 and 1991. Results ofthe sediment analyses indicated acetone, chloroform, methylene chloride, PCE, toluene, xylene, cadmium, chromium, and lead were the primary sediment contaminants. The primary surface water contaminants were acetone, chloroform, methylene chloride, PCE, toluene, 1,1,1 trichloroethane, cadmium, chromium, and lead.

The surface water and sediment of Soldier Creek were considered as potential exposure pathways for human receptors, but results ofthe 1993 risk assessment for these media indicated that there was not an unacceptable risk to human health.

INITIAL RESPONSE

The U.S. Environmental Protection Agency (EPA), U.S. Air Force, and Oklahoma State Department of Health signed a Federal Facilities Agreement (FFA) designating the Air Force as the only Potentially Responsible Party (PRP). Response actions initiated prior to the ROD are discussed below.

In 1986, excavation activities were conducted along East and West Soldier Creek to identify and eliminate potential sources of contamination to Soldier Creek. Approximately 7,500 cubic yards of sediment were removed. In 1990 and 1991, several industrial cross-connections were removed that rnay have been contaminating the Soldier Creek storm-water system. Between 1990 and 1993, fourteen solvent pits and USTs in the vicinity of Soldier Creek were removed or abandoned.

The SCSSW ROD was signed in September 1993. Contamination remains on-site, but there have been no unacceptable human health risks associated with the levels of contaminants detected. Numerous contaminants, however, were found to present an unacceptable ecological risk. These risks were based on concentrations of site contaminants, which exceeded the lowest

available ecotoxicological benchmark for the exposure pathway. The adverse effects were limited to a localized scale in on-base areas.

SECTION 3 REMEDIAL ACTIONS

Remedy Selection and Implementation

The ROD, signed in August 1993 provided for a limited action remedy for the SCSSW OU. The remedial action objectives for the OU were to prevent the ingestion of, or dermal contact with, sediment and surface water with contaminant concentrations greater than health-based cleanup goals and to prevent off-base migration of contaminants with concentrations greater than health-based cleanup goals. Existing or potential groundwater contamination was to be addressed separately under the Soldier Creek Off Base Groundwater (SCOBGW) OU due to the complexity of potential groundwater interactions between all of the OUs at Tinker AFB. The IWTP/SCOBGW investigations included evaluation of the interactions between the creeks and groundwater.

The baseline risk assessment determined that the Soldier Creek sediment and surface water did not pose a risk to human health or the environment in excess of the acceptable risk-based levels established by EPA. However, the environmental assessment conducted as a part of the baseline risk assessment was only qualitative and could not be used to fiilly assess ecological risk. Long-term monitoring would be used to determine if levels in the creek remain below the health-based cleanup goals over time and quantitatively evaluate the environmental risk, if any, existing at the OU. The remedial actions selected in the ROD incorporated the following components:

• A five-year monitoring program of Soldier Creek sediment and surface water at on-base and off-base locations to determine if contaminant migration has occurred and, if so, determine if migration has resulted in contaminant concenfrations greater than health-based cleanup goals.

• An ecological investigation (quantitative and qualitative) of Soldier Creek sediment and surface water to fiorther define potential environmental risk.

• Annual monitoring reports to present and evaluate monitoring results for levels exceeding health-based cleanup goals.

• A five-year ROD review to ensure that the remedy continues to provide adequate protection of human health and the environment or whether additional remedial actions are necessary.

A chronology ofthe remedy development and implementation activities for the SCSSW OU is provided in the Table 2 below.

Operation and Maintenance Requirements

There are no O&M requirements associated with the continued monitoring remedy. Flight line criteria at Tinker AFB have prompted upgrades to the landscape along West Soldier Creek. The channel of West Soldier Creek has also been concreted. This action serves as a facility improvement for Tinker's mission, as well as a remedial measure (although not identified as a ROD requirement) to minimize the potential for sediments to move off base and pose a human

health or ecological threat to downstream receptors.

Remedial Action Objectives

The selected remedial action goals for the SCSSW were based on results ofthe baseline risk assessment (RA) conducted for the OU (B&V, 1993 c), which included a quantitative baseline human health risk assessment (BHRA), and a qualitative ecological risk assessment (ERA). Results of the BHRA showed that potential risk to human health from Soldier Creek sediment and surface water was within acceptable risk-based exposure levels established by the EPA. The qualitative ERA identified several contaminants that may pose a potential environmental concem, however, additional study was recommended to fully characterize potential risk.

The health-based cleanup goals were identified in the ROD as to-be-considered (TBC) criteria to be used as guidelines for evaluating future concentrations of contaminants detected in Soldier Creek sediment and surface water. TBCs are evaluated in the five-year review with respect to any changes since the time of their development. TBCs can vary due to changes in site characteristics (e.g., receptors, exposures, or pathways) and/or characteristics ofthe contaminant (e.g., new toxicity information and level of contaminant). The TBCs were initially based on the existing site conditions and contaminant characteristics computed by back-calculating equations used in the BHRA (B&V, 1993b; 1993c).

The ROD response action was based on sediment and surface water data collected during Phase I and Phase II of the RI. For these media, the BHRA evaluated potential risks for incidental ingestion and dermal contact for adult workers and child/adult recreators. Based on the conceptual site model (CSM), which identifies and describes exposure pathways, which may be potentially complete for the site, ten reasonable maximum exposure (RME) scenarios were selected to represent the current and fiiture land use. The exposure pathways and RME assumptions initially evaluated in the BHRA are considered to be applicable to current conditions.

The qualitative ERA focused on the effects of contaminant exposure on general populations of aquatic and terrestrial species typical ofthe OU area (B&V, 1993 c). It was found that the presence of several metals in surface water and sediment (barium, cadmium, chromium, copper lead, nickel, selenium, silver, and zinc) were of potential environmental concem to aquatic species; however, additional data were needed to fiilly characterize this risk as well as the potential risk to terrestrial species.

Human Health Risk Assessment

The first annual human health risk assessment (HHRA I) was prepared to provide information on potential "currenf and future risks based on data for surface water and sediment samples collected in November 1994, and January, April, and June 1995. The stream segments that were sampled are shown on Figure 3. The data were also used to compare results with those ofthe RI (B&V, 1 993b) and determine if previous conclusions remained valid. Based on results ofthe second year of quarterly monitoring, the second annual HHRA (HHRA II) was prepared to address the same issues as the HHRA I. 'Current" data for HHRA II (collected in October 1995,

and March, May, and August 1996) were used to identify potential risk and also verify that previous conclusions remained valid. These issues were similarly addressed in the third annual HHRA (HHRA III) using monitoring results from samples collected in January and July 1997.

Although not impacting the overall results, slight differences in methodology are noted between the original BHRA and the long-term HHRAs:

• PCB/pesticide analyses were added as sampling criteria in the long-term monitoring study (these analytes were not included in the RI samples);

• Four stream segments were evaluated for risk in the long-term HHRAs (nine segments were evaluated in the BHRA); and

• Age-corrected skin surface areas for the potential receptors were used in the long-term HHRAs for evaluating exposure to surface water and sediments (these parameters were not corrected in the BHRA).

Despite these slight differences in approach, there were no unacceptable cancer risks or non-carcinogenic hazards calculated during any of the long-term HHRAs. Thus, under the "current" or future stream use conditions for potential on-base or off-base population exposures to sediment and surface water in the SCSSW OU, there continues to be no unacceptable human health risk.

Comparison of Data to Health-Based Cleanup Goals

Based on the remedial action requirements for the SCSSW OU, human health-based cleanup goals were developed to evaluate the long-term monitoring results. These health-based goals were calculated for each chemical using the most health-protective exposure scenario (i.e., the scenario associated with the highest calculated risk or hazard). The residential exposure scenario was used for chemicals found off-base and the constmction worker scenario was used for on-base chemicals.

Four sets of human health-based cleanup goals were developed based on acceptable risk levels established by the EPA. This included three levels for carcinogens based on the EPA-acceptable cancer risk range of 10"̂ (one additional case of cancer per one million), 10'̂ (one additional case per one hundred thousand), and 10"̂ (one additional case per ten thousand). One health-based risk level was also calculated for each non-carcinogenic chemical based on the target Hazard Index (HI) of 1.0. For chemicals with both carcinogenic and non-carcinogenic properties, the lower (more health-protective) level was selected. Since surface water is dynamic (constantly changing), the calculated health-based cleanup goals are referred to as "health-based indicators of water quality." Both sediment and surface water values, however, provide the basis for comparing chemical concentrations to health-based levels and for evaluating whether additional remedial action may be necessary at the site.

During the BHRA and subsequent long-term monitoring HHRAs, health-based indicators for water quality were not exceeded for any detected contaminants. No analytes in sediment samples exceeded the 10"̂ RAO, which is the highest TBC concentration for a chemical detected at the site based on the USEPA-accepted risk range (10'^ to 10" )̂. The third year long-term

monitoring annual report (WCFS, 1998) contains the results ofthe comparison of site data to the acceptable IO"'* to 10"̂ range of health-based cleanup goals.

TBCs are evaluated in the five-year review with respect to any new information on chemical toxicity, which may increase or decrease the TBC. Since the time of the third year monitoring report, toxicity data for two of the detected contaminants (alpha-chlordane and beryllium) have been updated (EPA, 1998). The new cancer and non-cancer toxicity data for alpha-chlordane show that the chemical is less toxic than indicated in the HHRAs. Beryllium was not identified as presenting a potential human health risk using the previous toxicity data, and although new data indicate that the chemical is slightly more toxic as a non-carcinogen, the change in the toxicity value is not significant for the site. [The change in the toxicity value would result in a decrease ofthe non-carcinogenic action level for sediments from 21,800 to 8,720 miUigrams per kilogram (mg/kg). Compared to the range of detected concentrations for beryllium in sediments (1.7 to 0.27 mg/kg), this change is not significant]. Since beryllium was not detected in surface water during the third year monitoring results, there is no effect on the level of risk for this medium. Additionally, the oral slope factor (SF) for beryllium has been withdrawn (the toxicity data show that beryllium is not carcinogenic by ingestion). Thus, the chemical would not be calculated as a carcinogen via ingestion of sediments (i.e., the calculated overall carcinogenic risk would decrease).

Ecological Risk Assessment

The ecological investigation mandated by the ROD for the SCSSW OU was conducted as part of the environmental monitoring program to quantify potential effects of contaminant concentrations on the biological environment ofthe creek (WCFS, 1997b). The main ERA field activities were performed during October 1994 and June 1995. One noted observation of the ecological survey was that no federally listed threatened or endangered species or their habitats were found to occur within the SCSSW OU.

For sampling data evaluated in the ERA, a constituent was selected as a chemical of potential concem (COPC) if it was detected in one ecological or quarterly-monitoring sample (i.e., detected in at least one sampling event and at one location) at a concenfration that exceeded the lowest available ecotoxicological benchmark for the specific medium. Using this screening process, forty-six COPCs (including chemical "groups" in some cases) were identified in either sediment, surface water, or both media. These forty-six chemicals, or groups of chemicals, included:

• Nineteen inorganics: aluminvun, antimony, arsenic, barium, cadmium, chromium, cobalt, copper, cyanide, iron, lead, manganese, mercury, molybdenum, nickel, selenium, silver, vanadium, and zinc;

• Eleven VOCs/SVOCs: acetone, benzidine, bis(2-ethylhexyl)phthalate, carbon di sulfide, chlorobenzene, 1 ,4-dichlorobenzene, methylene chloride, toluene, 2,3,6-trichloronaphthalene, triphenyl phosphine sulfide, and total xylenes;

• Four phenols and substituted phenols/nonylphenols: 2,4-dimethylphenol, pentachlorophenol, phenols and various substituted phenols (counted as one chemical group), and nonylphenols (counted as one chemical group);

Total PCBs (counted as one chemical group): Aroclor 1254 and other mixtures; Eight organochlorine pesticides: aldrin, alpha- and delta-BHC (counted as one pesticide), alpha-chlordane, dieldrin, endosulfan sulfate, heptachlor, heptachlor epoxide, and methoxychlor; Low molecular weight PARs (counted as one chemical group): acenaphthene, anthracene, fluorene, and phenanthrene; Medium molecular weight PAHs (counted as one chemical group): fluoranthene and pyrene; and High molecular weight PAHs (counted as one chemical group): benzo(a)anthracene, benzo(a)pyrene, benzo(g,h,i)perylene, benzo(k)fluoranthene, chrysene, dibenz(a,h)anthracene, and indeno( 1,2,3 -cd)pyrene.

At the concentrations estimated for direct exposures to strictly-aquatic organisms (algae, benthic and water-column invertebrates, and fish) and/or the doses estimated for indirect exposure (via the ingestion pathway) to terrestrial/semi-aquatic birds and mammals, sixteen of the forty-six chemicals were found to pose a potential threat to ecological species. In general, the potential risks to strictly-aquatic organisms were somewhat greater than the potential hazards to terrestrial animals. The potential risks associated with both direct (aqueous) and dietary exposures were largely, but not entirely, confined to on-base portions of East and West Soldier Creeks.

Results of the ERA showed that the most significant COPCs for sediments were cadmium, chromium, copper, nickel, silver, zinc, total PCBs, PAHs, certain organochlorine pesticides, and certain phenolic compounds. Among these, cadmium, chromium, copper, nickel, PCBs, and PAHs were the most ubiquitous. The ERA indicated that potential effects of these contaminants may extend downstream (northward) beyond the ERA study boundary at Interstate 40; However, the potential for downsfream hazards was not considered to be of major ecological significance, particularly at higher levels of biological organization (i.e., populations, communities, ecosystems).

The most significant chemicals in surface water were barium, cadmium, chromium, copper, lead, molybdenum, and zinc. All of these chemicals, except molybdenum, were ubiquitous, and were also considered, to some extent, as possible contaminants of concem for areas downsfream of Interstate 40. Copper and chromium were of particular concem due to their phytotoxicity and indirect effect on higher frophic levels. These two metals, as well as cadmium and zinc (and possibly barium), were also considered to possibly directly affect invertebrate and fish conimunities.

Chromium, PCBs, and high molecular weight PAHs appeared to be the most significant chemicals for the ingestion pathways of terrestrial/semi-aquatic receptors. However, the lack of relevant dietary toxicological data prevented detailed quantitative estimation of dietary risk to amphibians and semi-aquatic reptiles (e.g., certain turtles and water snakes), which may be the most sensitive wildlife receptors for the OU.

Toxicity tests (acute and chronic effects under controlled laboratory conditions) were also measured on ecological species exposed to sediment and surface water. With the exception of

conditions in off-base portions of West Soldier Creek, which did not appear to be as hazardous to aquatic receptors as indicated by the risk estimates described above (based on the hazard quotient I hazard index approach), the toxicity test results of the initial ERA generally corroborated the risk estimates. Biological surveys, particularly of benthic invertebrate and fish communities, also generally supported conclusions ofthe risk estimates.

Initial chemical-specific concenfrations referred to as preliminary remedial goal options (RGOs) were developed as protective levels for ecological receptors in sediment and surface water of Soldier Creek. These levels are similar to the human health-based cleanup goals and can be used for evaluating chemical concentrations detected in the on-going five-year monitoring efforts and for evaluating whether additional remedial action may be necessary at the site.

It should be noted that the ERA is based on very conservative exposure values and that the risk characterization is inflated by additive conservative assumptions. The degree to which exposures and toxicities are overestimated leads to a great deal of uncertainty in the assessment. Additionally, the adverse effects identified in the assessment were limited to a localized scale in on-base areas. Further data are necessary to more accurately characterize the extent of contamination and the associated potential hazards to ecological receptors in downsfream areas. Interpretation ofthe ecological significance ofthe ERA results is provided in Section 6.

Additional Remedial Actions

In addition, although it was not required by the ROD, additional corrective measures have been pursued as a means to alleviate the risk to human health and the environment. These measures include removal of contaminated soils in West Soldier Creek and cementing the on-base portion of the channel. In addition, contaminated sediments were removed from East Soldier Creek and the charmel was cemented around the dam near the IWTP.

SECTION 4 PROGRESS SINCE LAST FIVE-YEAR REVIEW

Protectiveness statement from ROD

As stated in the ROD, the protectiveness statement is as follows: the selected remedy is protective of human health and the environment because monitoring of the concenfrations of the chemicals of concem in Soldier Creek sediment and surface water will be conducted and an ecological investigation will be performed. Continued monitoring will determine if a human health risk develops from these media at the operable unit. Implementation of the selected remedy does not pose any unacceptable short-term risks or cross-media impacts. Because carcinogenic risk levels are within the acceptable risk range (lE-04 to lE-06) and the His for noncarcinogens are less than 1.0, the sediment and surface water contamination at the Soldier Creek, Sediment and Surface Water Operable Unit does not present a significant threat to human health. Based on the qualitative environmental assessment conducted as a part of the baseline risk assessment, a significant threat to the environment does not exist. Therefore, the only response action required at this time is that specified in the selected remedy. The continued

monitoring of Soldier Creek sediment and surface water at on-base and off-base sampling locations will be adequate to address operable unit contamination because the concentrations of the sediment and surface water COCs do not exceed the remediation goals (risk-based cleanup levels) established for the operable unit. The ecological assessment to be conducted will determine the effects of contaminant concentrations on the biological environment of Soldier Creek. Yearly and at the time ofthe five-year review, the results ofthe monitoring program will be evaluated to determine if a remedial action needs to be implemented or additional monitoring needs to be conducted at the operable unit.

Protectiveness Statement from last Five-Year Review

As stated in previous Five-Year Review: The results from the ERA indicated that potential for ecological risk in the area. Subsequent remedial measures have been implemented by OC-ALC/EM to remove or reduce potential contaminant sources and minimize the potential for sediments to move off base and pose a human health or ecological threat to downsfream receptors. Continued annual monitoring and evaluation will determine the need for fiirther remedial actions, if necessary.

Status of Recommendations from Last Five-Year Review

Recommendations made in the previous five-year review are as follows: 1) To ensure that exposure to and migration of contaminants does not occur at concentrations greater than human health based and ecological remediation goals, annual monitoring efforts and risk evaluations should continue, 2) the additional sampling details identified in the initial ERA should be added to the next round of monitoring to more clearly define the ecological risk, and 3) the new toxicity data should be used in subsequent HHRAs. As of this Five-Year review, all recommendations from the previous review have been completed.

As a result of recommendations made in the previous five-year review, the second ERA generated new HHRAs using current toxicity data. Additional objectives of the second ERA were as follows: 1) to evaluate the effects of rerouting (removal) of IWTP and STP discharges on the distribution of COECs and any adverse ecological impact in East Soldier Creek, 2) to reduce the uncertainty associated with the previous exposure and toxicity assessments and 3) to include improved/expanded sample analyses. Incorporation of those factors mentioned above into the second ERA indicated no detriment to ecological risk. Further discussion on the risk assessments is included in the conclusions in Section 8.

Additional Progress Since last Five-Year Review

As previously mentioned, although it was not required by the ROD, additional corrective measures have been pursued as a means to alleviate the risk to human health and the environment. These measures include removal of contaminated soils in West Soldier Creek and cementing the on-base portion of the charmel. In addition, contaminated sediments were removed from East Soldier Creek and the channel was cemented around the dam near the IWTP.

SECTION 5 FIVE-YEAR REVIEW PROCESS

A level 1 review was conducted for the SCSSW OU. The review was conducted by Sara Sayler of OC-ALC/EMPE. The key elements of the five-year review included: document review, interviews, site inspection, evaluation of findings and report preparation.

Site Inspection

Interviews An interview was conducted with the SCSSW Site Manger James Dawson (OC-

ALC/EMPE) on November 16, 2002, to discuss the status of the SCSSW OU.

Site Visit A site visit was conducted on January 8, 2003. During the site visit, landscaping and

current conditions of portions ofthe SCSSW site was noted. A walking/jogging path has been constmcted along the creek. No distressed vegetation was observed.

Community Involvement

Community involvement was initiated at the October 29*, 2002 community advisory board (CAB) meetings by announcing that a Five-Year Review process was underway. In addition, community comments/concems were solicited during the January 28*, 2003 CAB meeting.

Data Review

Since the time of the original BHRA and qualitative ERA, additional information on the nature and extent of contamination has been collected, including additional sediment and surface water sampling, as well as information on pesticides and polychlorinated biphenyls (PCBs) not previously evaluated. A review of the Seventh Year Long Term Monitoring Annual monitoring data is discussed below. Table 3 in Appendix A contains the sample results ofthe Seventh Year Long Term Monitoring. This table includes data obtained from November 1994 to September 2001.

SURFACE WATER

Metals Twenty metals were detected during the seventh year of monitoring. Total metals detected

in surface water by Method 6010/6020/7740 were: aluminum, antimony, arsenic, barium, beryllium, cadmium, calcium, chromium, cobalt, copper, iron, lead, magnesium, manganese, nickel, potassium, sodium, thallium, vanadium, and zinc. Metals concentrations in surface water did not exceed BHRA or HHRA I screening criteria during the seventh year of monitoring. Metals concenfrations in surface water samples have not exceeded screening criteria during the past seven years of long-term monitoring.

PCBs and Chlorinated Pesticides No PCB or pesticide analytes were detected in surface water samples during the seventh

year of monitoring. Therefore, PCB and pesticide concentrations did not exceed BHRA or HHRA I risk-based screening criteria in surface water. PCB and pesticide concentrations in surface water samples have not exceeded screening criteria during the past seven years of long-term monitoring.

Semivolatiles Bis(2-Ethylhexyl)phthalate and Diethyl phthalate were the only semivolatile compounds

detected in surface water during the seventh year of monitoring. Bis(2-Ethylhexyl)phthalate was detected in five surface water samples. The maximum detected concentration of bis92-Ethylhexyl)phthalate was 8 micrograms/liter at QW06-SW-1701. Diethyl phthalate was detected in one sample at a concentration 1.1 micrograms/liter at QEl l-SW-1801.

Semivolatile concentrations did not exceed BHRA or HHRA I risk-based screening criteria in surface water during the seventh year of monitoring. Semi-volatile concentrations in surface water have exceeded screening criteria in only one sample during the past seven years of monitoring. During the fourth of sampling, bis(2-Ethylhexyl)phthalate exceeded the HHRA 10"̂ screening criteria at QE02, located on Outfall G.

Volatiles Toluene was the only volatile organic compound was detected in surface water during the

seventh year of monitoring. Toluene was detected in one sample (QW07-SW-1701) at 5 micrograms/liter.

Volatile concentrations in surface water did not exceed BHRA or HHRA I risk based screening criteria during the seventh year of monitoring. VOC concenfrations in surface-water samples have not exceeded screening criteria during the past seven years of long-term monitoring.

Wet Chemistry Surface water samples were analyzed for the following wet chemistry parameters: alkalinity,

chemical oxygen demand, hardness, total dissolved solids, total organic carbon, total suspeiided solids, chloride, and sulfate.

SEDIMENT

A total of 30 sediment samples were collected during the seventh year of long-term monitoring. Sample results can be found in Table 4 of Appendix A.

Metals Twenty four metals were detected during the seventh year of monitoring. Metals detected

by Methods 6010 and 7471 were: aluminum, antimony, arsenic, barium, beryllium, cadmium, calcium, chromium, cobalt, copper, iron, lead, magnesium, manganese, mercury, molybdenum, nickel, potassium, selenium, silver, sodium, thallium, vanadium, and zinc. Metals concentrations in sediment did not exceed BHRA or HHRA I screening criteria in any ofthe past seven years of long-term monitoring.

PCBs and Chlorinated Pesticides Aroclor 1254 was the only PCB detected in sediment during the seventh year of monitoring.

It was detected in one sample (SC-QW05-SD-1801) at 410 micrograms/kilogram. Pesticides and PCBs were not identified as potential COPCs in the BHRA. HHRA I carcinogenic and non-carcinogenic screening criteria for PCBs and pesticides were not exceeded during the seventh of monitoring.

Semi-Volatile Organics Twenty-six semirvolatile organic compounds (SVOCs) were detected during the seventh

year of monitoring. The highest SVOC concentration was pyrene (4,900 microgram/kg), which occurred in QW05-SD-1801. The most frequently detected SVOC with 23 detections in sediment samples was bis(2-Ethylhexyl)phthalate. Five SVOCs were identified as potential COCs by exceeding the 10" risk based screening criteria during the seventh year of monitoring. The PAHs benzo(a)anthracene, benzo(b)fluoranthene, benzo(a)pyrene and chrysene, exceeded the BHRA 10"̂ screening criteria in QW05-SD-1801. Benzo(k)fluoranthene, benzo(b)fluoranthene, and benzo(a)pyrene exceeded the HHRA 10"̂ screening criteria in QW06-SD-1801. Benzo(a)pyrene exceeded the HHRA 10"̂ screening criteria in QW05-SD-1801 and QW06-SD-1801 samples during the seventh year of monitoring. The primary source of release of PAHs to the environment occurs as a result of combustion emissions. Discharges may also occur from spills of fiiel oils, gasoline, etc., or from mnoff from sources such as roadways, asphalt parking lot, or railroad ties.

Historically, there has been an exceedence of 10"̂ BHRA and HHRA screening criteria for a series of PAHs ((benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene, benzo(k)fluoranthene, and chrysene). In the past, concentrations of analytes decreased off-base as compared to on-base. Prior to the seventh year, the only off-base West Soldier Creek exceedences of 10"̂ screening criteria (BHRA and HHRA I) occurred during the 3Qfr lYr and lEvent3Yr-monitoring events in segment QW05. The only off-base East Soldier Creek exceedences of 10"̂ screening criteria (BHRA) occurred during the 4Qtrl Yr- monitoring event in segment QEIO. Analytical results from the furthest downstream segment of East Soldier Creek (QEl 1) have not exceeded BHRA or HHRA I screening criteria during any sampling event since the onset of long-term monitoring.

Volatiles Seven volatile compounds (VOCs) were detected in sediment samples during the seventh

year of monitoring. The VOCs detected during the seventh year of monitoring are presented in Table 3 of Appendix A (Table 3 also includes all sample data from November 1994 through September 2001). Volatile concenfrations in sediment did not exceed BHRA or HHRA I screening criteria. The highest VOC concenfration was chlorobenzene detected in sample QEl 1-SD-1701 at 3,400 microgram/kg.

EIGHTH YEAR SAMPLING EVENT

At the time of this writing, only the First Event of the Eighth Year Sampling Report had been completed. The results are discussed in the following text.

The sampling was conducted from April 10-11, 2002. A total of six surface water samples

and twelve sediment samples were collected during the field effort. Contaminant concentrations associated with this sampling event were compared with risk-based screening criteria which were based on exposure factors developed in the BHRA conducted as part ofthe Rl/FS and the HHRA I for human health.

BHRA Screening Exceedances No exceedances of BHRA screening criteria were identified for surface water analytical

results from East Soldier Creek and West Soldier Creek. Sediment analytical results did not exceed BHRA screening criteria for the non-carcinogenic screening criteria or IO""* carcinogenic risk.

Sediment analytical results exceeded BHRA 10"̂ screening criteria in a segment located off-base East Soldier Creek (QEll). No screening criteria were exceeded on West Soldier Creek or on-base East Soldier Creek. The BHRA contaminants of concem with concenfrations in excess of 10"̂ carcinogenic screening criteria were benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene, benzo(k)fluoranthene, and chrysene.

HHRA I Screening Exceedances No exceedances of HHRA I screening criteria were identified for surface water analytical results from East Soldier Creek and West Soldier Creek. Sediment analytical results did not exceed HHRA I non-carcinogenic screening criteria or screening criteria for 10"̂ or 10""* carcinogenic risk.

Sediment analytical results exceeded HHRA I 10"̂ screening criteria in two segments located off-base East and West Soldier Creek (QEl 1 and QW06). No screening criteria were exceeded on-base East Soldier Creek, or on-base West Soldier Creek. The HHRA I contaminant of concem with concenfrations in excess of 10" carcinogenic screening criteria was benzo(a)pyrene.

Tables 5 and 6 of Appendix A contain the results of the BHRA and HHRA 10"̂ Screening Criteria respectively.

SECTION 6 TECHNICAL ASSESSMENT

Question A: Is the remedy functioning as intended by the decision documents'! The remedy specified by the ROD included only requirements for sampling at specific locations in and around the OU. The past five years of sampling indicated no consistent areas of concem. Given this information, the remedy can be considered to fiinction as intended.

Question B: Are the exposure assumptions, toxicity data, cleanup levels, and remedial action objectives (RAOs) used at the time of the remedy selection still valid? Any changes in these parameters have been accounted for in additional rounds of both ecological and human health risk assessments.

Question C: Additional information arisen to question the protectiveness of the selected remedy"? Not at this time.

SECTION 7 ISSUES FROM PREVIOUS REVIEW

The following are comments and subsequent OC-ALC/EM responses pertaining to the Soldier Creed Sediment and Surface Water section ofthe previous Five-Year Review document:

1) Q: What was the basis for the change in the SCSSW OU boundary? A: The original RI sampled Soldier Creek all the way to Reno Avenue. The sampling

area was reduced based on results from the RI. The sampling area was reduced to approximately 1-40 since the RJ indicated that this sampling area would be sufficient.

2) Q: What is the status of the ERA? A: On-base areas were excavated and removed. Sampling still occurs at the base boundary and off-base to confirm that there is no contamination there. Because the contaminants were removed, there is no longer a necessity to address ecological issues beyond what is done in the annual reports.

3) Q: Are there any known off-base wells known to be used for drinking water purposes? A: To the best of our knowledge, there are no off-base wells known to be used for drinking water.

SECTION 8 CONCLUSIONS

Interpretation of Human Health Significance

As required by the ROD, the five-year monitoring program for the SCSSW OU has been implemented. Over the five-year duration of the momtoring program, health-based indicators for water quality (health-based cleanup goals) were not exceeded for any chemical detected in water. Additionally, no analytes in sediment samples exceeded the lE-04 RAO, which is the highest TBC level (human health-based action level) for a detected chemical based on the EPA-acceptable risk range (lE-06 to lE-04).

In addition to these results, the quantitative HHRAs did not show an unacceptable health risk. Results ofthe HHRAs for the first three years ofthe monitoring program, as well as results of the BHRA, indicate that under "current" or fiiture stream use conditions there is no unacceptable human health risk (cancer or noncancer risk) for potential on-base or off-base receptors due to sediment and surface water exposures for the SCSSW OU.

Interpretation of Ecological Significance

Initial ERA Results The initial ERA indicated that forty-six chemicals, or chemical groups, were of ecological

concem (pesticides, PCBs, PAHs, and other volatile and semi-volatile compounds). Ecological exposures were found to pose some risk of acute and chronic, sub-lethal effects to certain

individual receptors or individuals of receptor classes.

The study indicated that the ecological exposures and effects were largely confined to the on-base portions of the SCSSW OU. The concentrations of the PAHs were found to vary between sampling segments and sampling events suggesting that multiple on-base origins for the PAHs may exist. For example, highest PAH concentrations for the second year of monitoring occurred in the stream segment representing Outfall G, but during the third year of monitoring, many of the highest PAR concentrations occurred in the segment representing Outfall F. Data also indicated that discharge from Outfall G is a possible source of the PCB contamination. Although all electrical transformers with PCB-containing oil were replaced at the base in 1989, minor leaks or spills of old transformer oil may have previously entered the storm drain system. There are no known industrial processes that use PCBs in the area.

The ERA states that the adverse affects are clearly limited to a localized scale. This is also why results showed that the most ecologically-relevant actual or potential effects are those on strictly-aquatic conimunities (i.e., algae, benthic and water-column invertebrates, fish) and small terrestrial/semi-aquatic animals. The ERA states that it is unlikely that larger terrestrial vertebrates (wildlife) are at much risk from site-related chemicals.

The conclusions of this limited initial ERA also indicate that the risk characterization is inflated by additive conservative assumptions and that there is much uncertainty related to the degree to which exposures and toxicities are overestimated. The conclusions indicate that better understanding of the ingestion-pathway exposures is needed (as opposed to estimating dietary constituent concentrations of chemicals) and additional sampling may be required. As an example, the ERA suggests sampling and analyses of plant tissues (particularly finits), amphibians, and/or small mammals to provide a better understanding ofthe dietary exposures to higher-level consumers as well as more insights into the actual availability for direct uptake of the chemicals.

Second ERA Results completed since last Five-Year Review Two basic factors led to the second EA: 1) salient changes in conditions within the SCSSW OU - specifically, the complete removal of the Industrial Waste Treatment Plant and Sewage Treatment Plant effluents, and 2) the substantial uncertainty associated with risk characterization in the first EA. In order to reduce the uncertainty associated with the previous exposure and toxicity assessments, expanded and/or improved procedures intended to fill, or mitigate, many of the key data gaps identified by the initial EA were developed. This was done by: 1) reviewing analj'tical methodologies to obtain increased analytical sensitivity for some analyses, 2) expanding replication of samples to increase statistical confidence, 3) sampling biological tissues in multiple potential forage or prey items, 4) measuring several physicochemical characteristics to provide further insight into the fate and transport (especially bioavailability) of the COECs, and 5) developing biota-sediment accumulation factors using field-collected biological tissues and data from bioaccumulation tests conducted in the laboratory. Based on the ecological endpoints previously established and focusing on the COECs identified during the initial EA, the second EA re-evaluates exposures to ecological receptors in light of changed conditions, updated toxicological information and the expanded and/or improved site-specific information obtained in 1997.

Interpretation of ecological significance is summarized as follows. The estimated and apparent adverse effects of several of the COECs, based on the results of this second EA, suggest impact at the population and community levels, primarily to strictly-aquatic receptors and small semiaquatic vertebrates). However, these effects are largely confined to on-base portions ofthe SCSSW OU. In addition, interpretation of significance is blurred by the overt presence of numerous other stresses, particularly the extensive physical modifications of habitats in both creeks.

SECTION 9 DEFICIENCIES

There were no deficiencies identified for the second Five-Year Review of the SCSSW OU. Recommendations identified in the previous Five-Year Review were carried out.

SECTION 10 RECOMMENDATIONS

Based on results of the HHRAs and comparison of data to health-based action levels, there is no unacceptable risk to human health for the SCSSW OU.

In addition, numerous activities have occurred in the area of the SCSSW OU that serve to remove or reduce potential contaminant sources. Certain remedial measures have also recently been implemented by OC-ALC/EM at West Soldier Creek. Flight line criteria at Tinker AFB have prompted upgrades to the landscape along the creek. The channel ofthe creek has also been concreted. This action serves as a facility improvement as well as a remedial measure (although not identified as a ROD requirement) to minimize the potential for sediments to move off-base and pose a human health or ecological threat to downstream receptors.

Protectiveness of the environment has been attained by these remedial responses. As required in the ROD for this site, annual monitoring efforts were carried out during the previous five years to ensure no danger to human health or the environment exists. However, since there have been no exceedences of health based screening levels (based on IO""*) in the sampling over the past five years, it is recommended that sampling be discontinued at the SCSSW OU and the site be considered closed in accordance with the ROD.

SECTION 11 NEXT REVIEW

After gaining regulatory acceptance of this Five-Year Review, Tinker will request de-listing ofthe OU. If the site is de-listed, no additional Five-Year Reviews will be required.
