Problems/Comments

A total of four USTs have been removed from the site: a 500 gal. used oil (w/ 100 cubic yards of contaminated soil) in 1990; and a 1000 gal. gas UST, a 1000 gal. diesel UST, and a 1000 gal. HOT in 1992. A total of 24 cubic yards of contaminated soil was removed from the gas and diesel UST excavations. No soil was removed from the heating oil UST. Instead the excavation was backfilled at the location of the former heating oil UST, due to proximity to the building on site. Groundwater underneath building, at 13.5 feet bgs flowing in the south by southeast direction, has contamination above ADEC cleanup levels. Subsurface soil is impacted by contamination as well. Precence of surface soil contamination remains unknown. LUST Trust #89-3-5-0-292-2. Lots 7 and 8, Block A, Chena Industrial subdivision.

8/22/1989 Report or Workplan Review - Other On October 28, 2005, the ADEC received Re: Soil Contamination Studies, Lots 7 & 8, Block A submitted by Shannon & Wilson and dated August 22, 1989. To evaluate potential soil contamination, site activities included: collection of composite samples from stained surface soils, collection of a waste oil sample from the 500 gallon waste oil tank, and collection of soil samples from the three soil borings B-1, B-2, and B-3. Boring B-3 was advanced adjacent to the regulated 500 gallon waste oil tank and borings B-1 and B-2 were advanced down gradient of the 1,000 gallon diesel and gasoline regulated USTs. During the drilling of borings B-1 and B-2, a hydrocarbon odor was noted at various depths and a sheen was noted at the 15 feet below ground surface (bgs) groundwater interface. Soil samples collected at B-1 contained total petroleum hydrocarbons (TPH) up to 460 mg/kg at a depth of 12.5 to 16.5 ft. bgs. Soil samples collected at B-2 contained benzene up to 0.2 mg/kg at a depth of 10.0 to 11.5 ft. bgs. Soil samples collected at B-3 contained TPH up to 6,520 at a depth of 0.5 ft. bgs. The waste oil sample collected, analyzed for PCBs and metals, contained lead at 629 mg/kg. A composite sample collected at the south west corner of the building from surface fuel stains contained TPH up to 69,000 mg/kg. Grant Lidren

8/13/1990 Update or Other Action The ADEC received Monitoring Removal of Waste Oil storage Tank submitted Shannon & Wilson dated August 13, 1990. A 500 gallon waste oil UST, located south of the building, was removed on July 2, 1990. Soils around tank were stained gray and had a hydrocarbon odor. Contaminated soil was segregated on a liner. Excavation of soil from the northern side of excavation was limited by the building resulting in visually stained soil left under the building. Analytical soil samples collected at the northern end of the excavation contained up to 45,000 mg/kg TPH and 1.8 mg/kg PCE. Groundwater was not encountered in the excavation. Grant Lidren

2/9/2012 Update or Other Action On this date, ADEC received the ARRC UST Soil and Groundwater Investigation 1990 Phillips Field Road submitted by RSE, dated January 2012. Two soil borings were advanced and completed as temporary monitoring wells TW-1 and TW-2. Two soil samples were collected from each boring. TW-1D and TW-X were collected at 17 feet bgs and TW-2A & TW-2C were collected at 2 ft. bgs, based off highest screening level and at the groundwater interface at 12 ft. bgs respectively. Only soil sample TW-2A contained contamination above ADEC cleanup levels with DRO at 4,520 mg/kg(note: this is biased low, there was 0% surrogate recovery due to dilution). Groundwater samples collected from TW-1 &TW-2 did not contain detectable levels of contaminants. A groundwater sample collected from MW-3 contained DRO at 0.449 mg/L and GRO at 0.0315 mg/L, which is below cleanup levels. After sampling, TW-1 and TW-2 were decommissioned. Additionally, historic MW-4 and MW-5 were also removed and decommissioned. Grant Lidren

Monitoring Well TW-3 will be installed upgradient of the former diesel and gas USTs. Two soil samples will be collected: one soil sample at the groundwater interface and one at the highest screening level and/or olfactory presence of contamination. If no contamination is detected by screening or olfactory senses, then the second sample will be collected from the surface soil 0 to 2 feet bgs. Groundwater will be sampled from TW-3 and historic MW-3 and analyzed for GRO, DRO, RRO, and BTEX. Grant Lidren
11/13/2012 Site Characterization Report Approved On this date, ADEC received the Groundwater Monitoring Report 1990 Phillips Field Road submitted by FES, dated October 26, 2012.

A temporary well was installed adjacent to the soil boring to a depth of 18 feet bgs. A groundwater sample collected from the temporary well did not contain petroleum contaminants above Table C. GW Cleanup Levels. Groundwater samples collected from historic MW-3, from a depth of 15.97 feet bgs, contained DRO up to 0.904 mg/L, which is below Table C. GW Cleanup Levels. An odor was noted from the MW-3 GW. Grant Lidren
