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.
Sump vault separations allowed oily water to enter soils beneath liner. Subsurface investigations, bioventing, and monitoring is being tracked under the Alyeska VMT East TF Biovnet/ETF Summary informational file # 1200.38.017.

|7/22/1992||Update or Other Action||Receipt of report on 1991 subsurface investigation at ETF entitled East Tank Farm Sumps Subsurface Investigation Status Report which concludes that the lateral extent of contamination near sump associated with Tank 7 may not have been delineated. Report does not include any figures showing were samples were collected. Concentrations up to 9,810 mg/kg residual-range hydrocarbons (result obtained by calculation from analytical results) and 1,100 mg/kg diesel (EPH). GRO and BTEX results below Method Two migration to groundwater but results should be considered biased low due to holding time exceedance. Also, samples were not likely methanol preserved during this time period.||Keather McLoone|
|3/25/1993||Update or Other Action||Receipt of ETF Tank # 5 and Tank # 7 Subsurface Soil Investigation. Report includes boring logs. Borings were advanced and one to three soil samples selected from each boring based on staining and/or PID readings. Most samples collected from Tank #7 area and all were collected at subsurface depths. In these, TPH-diesel ranged from ND to 7,800 mg/kg, TPH-gasoline from ND to 2,200 mg/kg, TRPH from ND to 12,000 mg/kg, and benzene from ND to 0.7 mg/kg. Heterotrophic plate counts from six soil samples ranged from 320 to 18,000 CFU/mL. Residual-range hydrocarbons were also calculated by subtracting VPH and EPH.||Keather McLoone|
