Problems/Comments

Historical release (early 1980s) of JP4 fuel was discovered during the construction of a building foundation. The Eielson pipeline is owned by the U.S. Army Garrison Alaska. Department of Defense determined Defense Energy Support Center (now DLA-Energy) to be the responsible party. The affected area is approximately 5 acres located between Baker Road and the intersection of the pipeline and Moose Creek Avenue. The pipeline transported a variety of fuels (arctic grade diesel fuel, aircraft turbine JP-4 fuel, automotive combat gasoline, Avgas grade 115/145, JP-4, JP-8, vehicle leaded motor gasoline [Mogas] and unleaded Mogas) and thus contaminants of potential concern are BTEX, GRO, DRO, RRO, PAHs, EDB and lead. Soil and groundwater have been sampled in several times since 2003. Groundwater was sampled in summer 2011, 2012, and 2016. The most recent results from 2016 showed drinking water sample results were below 18 Alaska Administrative Code (AAC) 75.345 Table C cleanup levels (ADEC. 2017a), protective of groundwater and drinking water. Very low level concentrations of gasoline range organic compounds (GRO), diesel range organic compounds(DRO), and total lead were detected in various pre-GAC and tap water samples. All other drinking water analytes were not detected in the samples. In soil, benzene, GRO and DRO were detected at concentrations above cleanup levels. A Remediation System was installed in July 2018 for soil vapor extraction. The system was deemed functional and operational, but the system is not operating as of 1/1/2019 due to lack of an operations and maintenance contract.

7/23/2007 Update or Other Action An Initial Site Characterization Report prepared by Michael L. Foster & Associates, Inc. was recieved by ADEC on October 26, 2006. This report delineates the nature and extent of contamination discovered while a private home owner (David Petroske) was excavating a foundation located approximately 80ft north of the MAPCO to Eielson Pipeline near Milepost 20.3. An initial Site Characterization effort was undertaken in September of 2003. Additional Site Characterization efforts were undertaken in September of 2004. The affected area is located between Baker Road and the intersection of the pipeline and Moose Creek Road. This area is approximately 400ft by 600ft or approximately five acres. The area is a spruce-birch forest with thick undergrowth of vegetation. The vegetation does not appear to be stressed by the soil and groundwater contamination. Three private water wells have each been sampled twice with analytical results indicating non-detect for GRO, DRO, and BTEX. Zachary Richter
5/2/2008 Meeting or Teleconference Held Attended a meeting with Jack Appolloni and Michael L. Foster to discuss future plans for the site. ADEC requested that a conceptual site model be completed for the site to determine if all the exposure pathways have been evaluated and to help determine what future remediation and/or monitoring is required for the site. Deborah Williams
8/20/2009 Update or Other Action Received Monitoring Well Installation Work Plan for placement and construction of 6 wells. Follow up email and phone call sent. Further discussion is required prior to formal approval of plan. Fred Vreeman
1/7/2011 Document, Report, or Work plan Review - other 2010 Site Summary Report, prepared by OASIS on behalf of DESC. This report summarizes all site characterization work and is designed to provide a comprehensive basis for planning future efforts that result in final remedial decisions, a long-term monitoring plan and a schedule for closure. 2009 testing showed soil and groundwater contamination above cleanup levels for GRO, DRO and BTEX. Kathleen Beutel
1/19/2011 Meeting or Teleconference Held ADEC attended an initial stakeholders' meeting. DLA-Energy (the responsible party) and its contractor, OASIS, presented a site history and upcoming plans to sampling drinking water wells twice and conduct quarterly groundwater sampling in 2011. Another stakeholders' meeting to discuss results of the upcoming well sampling was scheduled for May 11, 2011. Kathleen Beutel
2/22/2011 Document, Report, or Work plan Review - other CS staff approved a work plan for residential drinking water well sampling within 1/4 mile of the contaminant plume. The work plan outlines two drinking water well sampling events scheduled for 2011. The winter sampling event will analyze 15 wells for DRO, GRO, EDB, VOCs, SVOCs, lead and sulfolane. The summer sample event will test only the seven wells closest to the contamination and omit lead and sulfolane testing. Because this water could be used for gardening or recreational activities, total aromatic hydrocarbons (TAH) and total aqueous hydrocarbons (TAqH) will be calculated from VOC/SVOC data and compared to surface water standards. If well logs or other well construction information cannot be obtained from homeowners, a downhole camera may be used (with homeowner consent) during the summer sampling event. The well will be disinfected and coliform bacteria testing will be completed following use of the camera. Kathleen Beutel
4/15/2011 Update or Other Action Residential drinking water well sampling was conducted in March 2011. 15 residents were contacted and 11 wells were sampled. Wells located closest to the plume were sampled both prior to the treatment system and at the tap. Wells further away were sampled only at the tap. Results were communicated to homeowners via letters. A summary report will be submitted to DEC following a second round of sampling in summer 2011. All wells were non-detect for GRO, DRO, toluene, ethylbenzene, xylenes and sulfolane. Benzene was detected below cleanup levels from the tap at one residence. At another residence, benzene was non-detect upstream of the treatment system but above the cleanup level (0.12 mg/L) at the tap. Follow-up sampling will be conducted at the residence. Lead was detected upstream of the treatment system at three residences but was non-detect at the tap at all three residences. Kathleen Beutel
5/12/2011 Meeting or Teleconference Held Contaminated Sites staff attended a stakeholders’ meeting regarding recent residential well sampling at the Moose Creek site at Milepost 20.3 of the Eielson Pipeline. Several homes are located within a half-mile of the five-acre area of GRO, DRO and BTEX contamination. Eleven residential wells were sampled for GRO, DRO, BTEX, EDB, PAHs, lead and sulfolane. All GRO, DRO, EDB and sulfolane results were non-detect. One residence will be re-sampled this week because benzene was non-detect upstream of the treatment system but above the cleanup level at the tap (0.12 mg/L). Three homes had lead upstream of the treatment system (0.012 - 0.2 mg/L) but all three were non-detect at the tap. Wells will be sampled again in August and another public meeting will be held on October 12. Kathleen Beutel
6/1/2011 Update or Other Action Follow-up residential drinking water sampling was conducted at the residence at which benzene was detected at the tap (see 15 April 2011 entry for details). All BTEX compounds and GRO were non-detect at the tap. Another round of drinking water sampling will be conducted this summer. Kathleen Beutel

7/19/2011 Meeting or Teleconference Held Contaminated Sites (CS) and DLA staff participated in a meeting to discuss three sites: Moose Creek, Manchu Road and the Eielson Take-Off Pad. CS and DLA staff discussed funding, plans for 2012 and the need to move these sites toward closure. No groundwater monitoring will be conducted at the Take-Off Pad in 2011; instead, a more comprehensive plan that will include replacement of frost-jacked wells, sampling for additional contaminants of potential concern and an effort to bound the dissolved-phase plume will be submitted in early 2012. All parties agreed that signed decision documents (DDs) will provide a clear path forward and possibly ease challenges in obtaining funding. It is anticipated that DDs for Manchu Road and the Take-Off Pad will be prepared within the next year and a DD for Moose Creek will be prepared within the next two years. Kathleen Beutel

9/19/2011 Update or Other Action Preliminary groundwater data received. The new monitoring wells (MW-07 and MW-08), which are located on the downgradient and upgradient ends of the plume, were non-detect for all parameters. Other monitoring wells had concentrations of GRO, DRO and benzene above cleanup levels. Results will be discussed at the October stakeholders' meeting and a report summarizing the 2011 field work will be submitted in the coming months. Kathleen Beutel
10/12/2011 Meeting or Teleconference Held Contaminated Sites staff attended a stakeholders’ meeting that summarized data collected this year at the Moose Creek site at Milepost 20.3 of the Eielson Pipeline. Drinking water wells were sampled twice this year and will continue to be sampled semi-annually. All results from the most recent round of sampling were non-detect. The ultraviolet optical screening tool was used this summer to fully delineate the soil contamination. Two new monitoring wells were installed at the up and downgradient edges of the plume; all results from these wells were non-detect. Wells within the source areas had concentrations of GRO, DRO, benzene and EDB above cleanup levels. The responsible party plans to conduct a soil-gas study this year at the residence closest to the plume and plans to delineate the lateral extent of the plume next year during a hydro-punch investigation. This will be followed by a feasibility study in 2013. Groundwater will continue to be monitored three times per year and pressure transducers continue to generate data regarding groundwater fluctuation and flow direction. Approximately ten residents attended the meeting. The next public meeting will be held February 15, 2012. Kathleen Beutel

2/15/2012 Meeting or Teleconference Held Contaminated Sites staff attended a stakeholders’ meeting regarding the Eielson Pipeline Milepost 20.3 – Moose Creek site. The responsible party, Defense Logistics Agency – Energy, shared results from 2011 including drinking water, soil gas, soil and groundwater data. No residential drinking water samples have exceeded the maximum allowable concentrations. Soil gas points installed around the residence closest to the plume were all non-detect. Additional site characterization data will be collected in 2012, and it is anticipated that cleanup options will be evaluated in 2013 and a decision document will be signed within the next two years. Approximately 7 residents attended the meeting. Kathleen Beutel
6/8/2012 Site Characterization Report Approved Contamnated Sites staff approved the final Moose Creek Site Residential Drinking Water Sampling Report. Drinking water wells were sampled twice in 2011. In winter 2011, pre- and post-treatment samples were collected at residences located closest to the release site, while other residences received tap-only sampling. The summer sampling event only included tap samples. In the winter, lead concentrations of up to 0.74 mg/L were identified upstream of the treatment system at four residences but were non-detect at the tap at all four residences. All analytes were non-detect during the summer sampling event. Drinking water samples will be collected at up to 14 residences in 2012. Pre- and post-treatment samples will be analyzed for gasoline range organics, diesel range organics, ethylene dibromide, volatile organic compounds, semivolatile compounds and lead. Kathleen Beutel
6/11/2012 Site Characterization Workplan Approved Contaminated Sites staff approved the Fiscal Year 2012 Site Investigation Work Plan. Field activities include two rounds of residential well and tap sampling, a hydropunch (direct-push) groundwater investigation, installation of up to eight new monitoring wells, soil sampling at the locations of the new monitoring wells and three rounds of groundwater monitoring. It is intended that the information obtained from the 2012 investigation, coupled with previous data and additional soil gas data to obtained in 2012, will provide information to update the conceptual site model and develop a remediation strategy. Kathleen Beutel
5/1/2013 Site Characterization Workplan Approved FY13 work plan approved. The Moose Creek Monitoring Work Plan provides for three rounds of sampling of groundwater at the site, two rounds of sampling of residential drinking water wells, and other ancillary tasks. The work plan also calls for two stakeholder meetings to be conducted. This work will proceed in conjunction with the Moose Creek Soil Gas Work Plan, previously approved on March 20, 2013. Results from the two work plans are expected to help establish the feasibility of various remediation options. Eric Breitenberger
8/7/2013 Site Characterization Report Approved FY 2013 Comprehensive report approved. Groundwater monitoring results indicate that the contaminant plume is probably stable or decreasing, however contaminant levels are still far above cleanup standards, with benzene up to 0.547 mg/L in MW-5. Drinking water results were all below action levels, with the exception of one sample which exceeded action levels for lead. The source of this exceedance is believed to be within the home’s plumbing system, as no exceedance was observed in another sample collected upstream (pre-filter) in the same residence. Eric Breitenberger
8/25/2014 Site Characterization Workplan Approved FY14 work plan approved. The Moose Creek Monitoring Work Plan provides for one round of sampling of groundwater at the site and one round of sampling of residential drinking water wells. Other ancillary tasks are also included. The frequency of groundwater and drinking water sampling will be reduced compared to previous work plans. DEC concurs that the reduction is warranted, due to the limited seasonal variability observed at the Moose Creek site. Eric Breitenberger
12/9/2014 Update or Other Action Proposed Plan approved. Eric Breitenberger
12/10/2014 Update or Other Action Feasibility Study approved. Selected Alternative is installation of a soil vapor extraction system and bioventing. Biosparging may potentially be added to the remedy. Eric Breitenberger
