Soil types consist of silty clay to depths ranging from 10 to 60 feet underlain by limestone and dolomite (Epler Formation, Beekmantown Group). Groundwater flow occurs in secondary porosity along solution channels or bedding and fracture planes in the rock. Depth to groundwater at the site is approximately 90 feet below grade.
Targeted Environmental Media:
 Dense Non-aqueous Phase Liquids (DNAPLs) - Fractured Bedrock
Major Contaminants and Maximum Concentrations:
- Tetrachloroethene (402 µg/L)
- Other (Monitoring wells)
- Chemical Oxidation (In Situ)
- Soil Vapor Extraction
- Bioremediation (In Situ)
- Other (ART Technology)
Comments:
Within nine months, the ART Technology had reduced groundwater contamination from 403 ug/l to below the Action Level of 50 ug/l at the point of compliance well more than 40 feet from the nearest ART Technology installation.
50 ug/l PCE
The site has received official closure from the state.
Radius of influence at a minimum of 40 feet.
