Problems/Comments

Building 2762/Former Carpenter Shop/Former Building 6214, which is located just east of IRP site ST16, is now occupied by the outdoor recreational facility and includes an office building, a repair shop and storage for outdoor equipment and vehicles. Drinking water well D is 0.38 mi N (downgradient) of the bldg. Drinking water well E may be nearby as well. Contamination west of the building likely is from previously-closed site ST16, which had a 5000-gallon MOGAS release from an underground fuel line in 1954. Please see ADEC file 107.38.039/Hazard ID 342 for more information about the contamination west of this building. There was a potential release when the facility was a carpentry shop. In addition, drums at a nearby former drum storage area reportedly leaked in 1986 and subsequently were removed. Contaminants of concern include POL, paint and solvent. A 2004 site investigation identified benzene contamination in soil with concentrations from 0.022 to 0.134 mg/kg and a 1000 square foot area of soil contamination from the surface to 4-6 feet below ground surface (bgs) located east of the building in the fenced area. In addition, DRO concentrations in soil of up to 269 mg/kg and a 900 square foot area of contaminated soil was identified south of the building from near the surface to 6 ft bgs. Groundwater samples were not collected south of the building. Sampling efforts in 2014-2016 identified arsenic, chromium, benzene, methylene chloride, 1,2,-Dichloroethane, and 1,2,4-Trimethylbenzene as exceeding the DEC human health cleanup level in subsurface soils. 2015 and 2016 site characterization efforts recommend excavation of subsurface soils for VOCs and fuels. Groundwater was not found to be impacted by soil contamination, however, an exceedance for chromium requires further investigation at this time.

Action Information

Action Date	Action	Description	DEC Staff
8/17/2004	Meeting or Teleconference Held	DEC met with the Air Force and their consultant to discuss a site characterization work plan. Comments were resolved and all parties agreed to eliminate use of inertial pumps for collection of groundwater samples for volatile organic analyses. Low flow peristaltic pumps will be used instead.	Sharon Richmond
8/18/2004	Site Characterization Workplan Approved	Staff approved plan to characterize groundwater contamination. Samples will be analyzed for fuel components and metals. ADEC approved installation of monitoring wells in addition to those identified in the work plan, so long as installation and sampling and analysis procedures adhered to work plan.	Sharon Richmond
1/20/2005	Site Added to Database	Benzene contamination present at site.	Deborah Williams
1/20/2005	GIS Position Updated	The source of the locational information was TopoZone Pro at NAD 83. Coordinates for this site are suspected to be in error and should be checked with PM.	Deborah Williams
1/20/2005	Site Ranked Using the AHRM	Site received a "High" priority using the AHRM.	Emily Youcha
1/26/2005	Update or Other Action	Site characterization report was reviewed comments were given. Two main areas of contamination exist near the building. Benzene contamination was found in the soil to the east of the building and exceeds ADEC Method Two migration to groundwater. Benzene and GRO contamination was also found to the west of the building and is thought to be part of a MOGAS spill associated with closed site ST16. ADEC recommended further characterization of the contamination associated with ST16 and Air Force should propose cleanup levels and technologies for the other area of soil contamination east of the building.	Emily Youcha
3/16/2005	Site Characterization Report Approved	Please note that ADEC does not consider this effort a complete characterization as required by 18 AAC 75.335. The site characterization report did not include a conceptual site model to assess the exposure pathways or an evaluation of cleanup technologies. ADEC expects the conceptual site model and evaluation cleanup technologies in a future proposed plan for each site. Based on the findings of this investigation, ADEC concurs with the following information for Building 2762 – Former Carpenter Shop: 1. Benzene-contaminated soils were found in test pits inside the fenced area east of Building 2762. Benzene-contaminated soils exist above Method Two cleanup levels in Table B2 at 18 AAC 75.341 from approximately 3-6 feet below ground surface. Diesel range organic (DRO)-contaminated soil was found south of the building, outside of the fenced area, with only one sample exceeding ADEC Method Two cleanup levels in Table B2. Ground-water contamination above ADEC cleanup levels in Table C at 18 AAC 75.345 does not currently occur at these two locations. 2. An additional area of benzene and gasoline range organic (GRO) contamination was found to the west of Building 2762 along Industrial Avenue in both the soil and ground water. Contamination in this area is thought to be from previously-closed Installation Restoration Program site ST16, which was a 1954 5,000-gallon MOGAS release. Benzene concentrations in ground water (up to 100 ug/L) exceed ADEC Groundwater cleanup levels in Table C for benzene (5 ug/L). ADEC expects further evaluation at this site in the near future. 3. There were five slight exceedances for total chromium, but no exceedances of the hexavalent chromium Method Two migration to ground water cleanup level.	Emily Youcha
8/3/2005	Update or Other Action	This site is funded by compliance money and is cost recoverable.	Emily Youcha
12/5/2005	Meeting or Teleconference Held	Staff discussed the contamination at this site with the EPA and Eielson AFB. EPA and Eielson believe the contamination in the southern part of the building, near the road, is associated with ST16. Contamination was found mostly in the smear zone and ground water.	Emily Youcha
12/5/2005	Update or Other Action	Staff received a Method 3 cleanup level proposal from Eielson AFB for the contamination discovered at the building. Contamination at the building (not including in the vicinity of ST16) exceeding Method Two soil cleanup levels includes benzene, DRO, GRO, and total chromium. Arsenic and barium exceed cleanup levels but are within the background ranges for Eielson. Contamination appears to be limited to between 0-3 ft below ground surface and did not migrate downward. Staff requested some clarification regarding the Method 3 input parameters (TOC and maximum concentrations) and a conceptual site model before the proposed alternative soil cleanup levels are approved.	Emily Youcha
8/4/2006	Update or Other Action	Staff received an updated copy of the Method Three calculation for this site. The migration to ground water cleanup levels are 0.141 mg/kg (benzene), 194 mg/kg (Chromium 6+), 1900 mg/kg (DRO), 2200 (GRO), 10,000 mg/kg (RRO). However, the maximum allowable concentration of GRO is 1400 mg/kg. The maximum concentrations detected at the site are 0.134 mg/kg (benzene) and 1.39 mg/kg (Chrom6+). The cumulative cancer risk is 2E-7 and hazard index is 0.13, both below our risk standards. This site is adjacent to a closed IRP site ST16 (former fuel line), where groundwater contamination was recently discovered. It is likely that the contamination associated with this building is not associated with the ST16 fuel line. However, the remaining groundwater contamination at ST16 should be addressed.	Emily Youcha

1/26/2005

Update or Other Action

Site characterization report was reviewed comments were given. Two main areas of contamination exist near the building. Benzene contamination was found in the soil to the east of the building and exceeds ADEC Method Two migration to groundwater. Benzene and GRO contamination was also found to the west of the building and is thought to be part of a MOGAS spill associated with closed site ST16. ADEC recommended further characterization of the contamination associated with ST16 and Air Force should propose cleanup levels and technologies for the other area of soil contamination east of the building.

Emily Youcha

3/16/2005

Site Characterization Report Approved

Please note that ADEC does not consider this effort a complete characterization as required by 18 AAC 75.335. The site characterization report did not include a conceptual site model to assess the exposure pathways or an evaluation of cleanup technologies. ADEC expects the conceptual site model and evaluation cleanup technologies in a future proposed plan for each site. Based on the findings of this investigation, ADEC concurs with the following information for Building 2762 – Former Carpenter Shop: 1. Benzene-contaminated soils were found in test pits inside the fenced area east of Building 2762. Benzene-contaminated soils exist above Method Two cleanup levels in Table B2 at 18 AAC 75.341 from approximately 3-6 feet below ground surface. Diesel range organic (DRO)-contaminated soil was found south of the building, outside of the fenced area, with only one sample exceeding ADEC Method Two cleanup levels in Table B2. Ground-water contamination above ADEC cleanup levels in Table C at 18 AAC 75.345 does not currently occur at these two locations. 2. An additional area of benzene and gasoline range organic (GRO) contamination was found to the west of Building 2762 along Industrial Avenue in both the soil and ground water. Contamination in this area is thought to be from previously-closed Installation Restoration Program site ST16, which was a 1954 5,000-gallon MOGAS release. Benzene concentrations in ground water (up to 100 ug/L) exceed ADEC Groundwater cleanup levels in Table C for benzene (5 ug/L). ADEC expects further evaluation at this site in the near future. 3. There were five slight exceedances for total chromium, but no exceedances of the hexavalent chromium Method Two migration to ground water cleanup level.

Update or Other Action

Staff received a Method 3 cleanup level proposal from Eielson AFB for the contamination discovered at the building. Contamination at the building (not including in the vicinity of ST16) exceeding Method Two soil cleanup levels includes benzene, DRO, GRO, and total chromium. Arsenic and barium exceed cleanup levels but are within the background ranges for Eielson. Contamination appears to be limited to between 0-3 ft below ground surface and did not migrate downward. Staff requested some clarification regarding the Method 3 input parameters (TOC and maximum concentrations) and a conceptual site model before the proposed alternative soil cleanup levels are approved.

Emily Youcha

8/4/2006

Update or Other Action

Staff received an updated copy of the Method Three calculation for this site. The migration to ground water cleanup levels are 0.141 mg/kg (benzene), 194 mg/kg (Chromium 6+), 1900 mg/kg (DRO), 2200 (GRO), 10,000 mg/kg (RRO). However, the maximum allowable concentration of GRO is 1400 mg/kg. The maximum concentrations detected at the site are 0.134 mg/kg (benzene) and 1.39 mg/kg (Chrom6+). The cumulative cancer risk is 2E-7 and hazard index is 0.13, both below our risk standards. This site is adjacent to a closed IRP site ST16 (former fuel line), where groundwater contamination was recently discovered. It is likely that the contamination associated with this building is not associated with the ST16 fuel line. However, the remaining groundwater contamination at ST16 should be addressed.
