Problems/Comments

Groundwater Zone 1 (OT27). Eskimo Creek Seeps 1 and 2 (SS11). Contaminants of concern include DRO and TCE. In the mid-1970s, 2 petroleum seeps observed at Eskimo Creek were reported to be discharging at the rate of up to 10 gallons per day. in 1981, floating product recovery pumps and a French drain were installed along the west bank of Eskimo Creek to intercept the floating fuel from Seep 1 before it reached the creek. The French drain was replaced in 1990 and a second French drain was installed upgradient of Seep 2 in 1994. Product recovery wells installed in 1992 were not successful in recovering floating petroleum product form the A-Aquifer. Various media samples were collected in 1995. In 1996 and 1997, a wetlands evaluation and human food chain evaluation were conducted for Eskimo Creek. The results indicated that contaminants have migrated into the wetlands and creek located downgradient of source areas; and further biota sampling was warranted. Various media samples were collected in 1997 and 1998 in 6 sampling events. Petroleum and TCE were consistently present in groundwater samples immediately downgradient of the French drains at both seeps. In 1999, additional biota and media samples were collected. No unacceptable risk was concluded. Zone 1 Record of Decision for Interim Remedial Action (dated November 2000) addresses risk to human health and the environment caused by hypothetical exposure to petroleum product floating on groundwater and TCE-contaminated (and TCE degradation products) groundwater, surface water, and sediment. Bioslurping was intended to address floating product, however 2001/02 pilot tests have proved not feasible and 2003 bioventing pilot test will be conducted. TCE is being monitored, and if action levels are exceeded then a permeable reactive wall will be installed for remedial purposes. The Eskimo Creek Treatment System will continue to be operated, monitored and maintained. And groundwater use restrictions will be implemented.

Eskimo Creek has been separated out as a separate site from the base wide IRP investigations done by CH2MHILL. Done by ADEC 12/27/91 Louis Howard Federal Facilities. This will aid in tracking remediation and scoring. Phase I site identification and HARM ranking score phase I site Number 1 "Fuel Seepage at Eskimo Creek" got a HARM score of 86. Source of seep is unidentified but may be an underground POL delivery systems, spill sites, underground storage tanks, or POL tanks 11, 12, 13, or 14 (POL tanks 11-14 are at right hand side of intersection of Storage Road and Cantonment Avenue) Any of the foregoing potential sources could also be minor or secondary sources. Latitude and Longitude is for Seep #1.

6/30/1989 Update or Other Action (Old R:Base Action Code = RAPR - Remedial Action Plan Review (CS)). CH2M Hill stage 2 workplan to assess 4 sites: North and South Barrel Dump Sites; Naknek River; and Eskimo Creek seeps. Remedial investigation and feasibility study occur in parallel. No Longer Assigned
6/30/1989 Update or Other Action (Old R:Base Action Code = RAPR - Remedial Action Plan Review (CS)). CH2M Hill QA/QC plan for various King Salmon Airport sites; the sites include the Eskimo Creek oil seep, North Barrel Dump, Naknek River seep, and the South Barrel Dump. A total of 17 sites were addressed by this QA/QC plan. No Longer Assigned
8/29/1989 Update or Other Action (Old R:Base Action Code = SI - Site Investigation). CH2M Hill site investigation. The airport was originally constructed in the early 1940s to support the war effort. The airport was turned over to the State of Alaska in 1959. The State continues to operate the site with the Air Force as the major tenant. A White Alice site was activated in 1957. It was deactivated in 1979 and replaced with an Alascom Satellite earth terminal. Only a small portion of the site is owned by the State. The majority is on military land. In 1980, 340 military personnel resided at King Salmon Airport. The north and south barrel dump site, Eskimo Creek Seep and Naknek River seep sites were tested for over 146 constituents of concern. Of these, 39 potential contaminants of concern were identified. High concentrations of TPH were identified in shallow wells and soils at this site. Floating product (>1 foot) was identified at the Eskimo Creek Seepage Site. Lead and petroleum hydrocarbon contamination levels at this site pose a threat to fish and wildlife (page 126). No immediate environmental threat was identified at the Naknek River Seep (page 126). Both the north and south dump sites could pose a threat to fauna since the detection limits used in analyses were greater than the chronic aquatic organism toxicity. Remediation, based on stage 2 sampling, at both barrel dump sites could include: no action; restricting site access; preventing the migration of contaminants. Containment preferred remediation route. The Naknek River and Eskimo Creek seeps will receive further sampling to identify a specific remediation response. In general, based on further sampling results, the alternatives are: no action, which will not occur based on preliminary site investigation; recovery of floating product; treatment of shallow groundwater; excavation of contaminated soils; restrict site access; containment. No Longer Assigned
10/17/1989 Notice of Violation Notice of Violation letter (although not titled such in subject line) to 5071 CSS/CC Air Force (Lt. Colonel Beil) from ADEC (Bruce Erickson, Anchorage/Western District Office Supervisor) regarding the unreported and unapproved oil / water separator removal resulting in oil seeping unreported into the wetlands of Eskimo Creek. No Longer Assigned
10/3/1990 Update or Other Action (Old R:Base Action Code = MS - Monitoring/Sampling). CH2MHILL Stage 2 IRP investigation report lists groundwater contaminated with: benzene at 1-23 ug/l, trichloroethene from 2-90 ug/l, naphthalene from 62-12,000 ug/l, 2-methylnaphthalene from 20-18,000 ug/l. Soil samples had: TPH from 4.2-47,700 mg/kg, lab analysis of soil obtained from installation of monitoring wells had TPH from 31.2-10,300 mg/kg, naphthalene detected at 8.86 and 37 mg/kg, 2-methylnaphthalene at 16-73 mg/kg. Extent of contamination at Eskimo Creek places it as the highest priority site for remediation, since this site is considered to pose the highest risk to human health and the environment. No Longer Assigned
10/3/1990 Update or Other Action (Old R:Base Action Code = SI - Site Investigation). CH2M HILL Final Draft Technical report under USAF contract # F33615-85-D-4535, Delivery Order # 012 sent to ADEC. This report only deals with 2 areas (Eskimo Creek and Naknek River) out of 4 past hazardous waste disposal and spill sites previously prioritized and grouped (stage 1). Naknek R. = Lower and Upper Naknek because of different contamination sources at each area along with a difference in the type and amount of contaminants of concern. In the Upper Naknek 2 plumes encompass 7,000 cubic yards and 9,000 cubic yards of contaminated soil above 100 ppm TPH at a depth of 3 to 5 '. Groundwater at 1 of 7 wells revealed aromatics of 12 ug/l benzene. Lower Naknek also consists of 2 distinct plumes of TPH to a depth of 3' The material at each plume above 100 ppm estimated to be 2,200 cubic yards and 3,300 cubic yards. Low levels of aromatics were detected in 2 wells below MCLs. Trichlorethane was detected in MW-57 at 120 ug/l exceeding MCL of 5 ug/l. Eskimo creek had 3 wells MW-22B, MW-28 and MW-38 exceed MCL for benzene (5 ug/l) 56, 23, and 8 ug/l respectively. 5 wells exceeded the MCL of 5 ug/l for trichlorethane MW-31, MW-47, MW-38, MW-30, MW-34 (18, 64, 26, 90, 29 ug/l respectively). 8 wells had naphthalene and methylnaphthalene ranging from 20 to 18,000 ug/l. Soil boring and hand auger soil samples revealed TPH from 4.2 ppm to 47,7000 ppm to depths to 20'. Various recommended remedial actions were presented for the 3 sites with all measures requiring monitoring for a minimum of 3 years to assess site conditions and the need for technical modifications to the selected remedial measures.

2/28/2003 Update or Other Action There were general wastewater permit discharge exceedences within the February monthly effluent samples at the treatment system. The filter media was changed in January and typically is effective for 4 to 6 months. The Air Force operator promptly transferred control to the backup filter system (the facility is equipped with a redundant filter system) and sent personnel to evaluate the situation. A stuck solenoid valve may have allowed the water to bypass the other filter vessels and flow directly into the organo-clay filter vessel. The monthly effluent sample and an organo-clay sample were collected for laboratory analyses on March 4. The February sample results consisted of the following: total aromatic hydrocarbons at 11.46 µg/L (10 µg/L WQS), total aqueous hydrocarbons at 12 µg/L (15 µg/L WQS), DRO at 3 mg/L (1.5 mg/L 18 AAC 75), and trichloroethene at 6.71 µg/L (5 µg/L 18 AAC 75).
