Site Report: Alaska Industrial Hardware UST #1
We make every effort to ensure the data presented here is accurate based on the best available information currently on file with DEC. It is therefore subject to change as new information becomes available. We recommend contacting the assigned project staff prior to making decisions based on this information.
A 4,000-gallon gasoline underground storage tank (UST #1) was removed from the northwest corner of the property on May 29, 1992. Based on field screening and visual and olfactory signs of contamination, the excavated soils were segregated into two separate stockpiles; suspected clean and suspected contaminated. A total of 5 confirmation soil samples (two from the excavation, one from the below the dispenser, and two from the soil stockpiles) and one grab groundwater sample were submitted for laboratory analysis. All soil and water samples were analyzed for benzene, toluene, ethylbenzene, and total xylenes (BTEX); the soil samples were also analyzed for total volatile petroleum hydrocarbons (VPHs). Following excavation, the suspected clean stockpile was used to backfill the excavation. The dirty stockpile remained onsite, pending analytical results.
Xylenes and VPH were present in the soil samples; however, at concentrations below the ADEC cleanup levels. Xylenes were also present in the groundwater below ADEC cleanup levels. Benzene, toluene, and ethylbenzene were not present in the soil or water samples above laboratory’s detection limits.
