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.


Soil contaminated with diesel and gasoline range hydrocarbons released in the pump area. Concentrations above 1,000 milligrams per kilogram (mg/kg) extractable petroleum hydrocarbons (EPH) were obtained east and south of the pump area excavation. Xylenes appear to be the predominant fraction of benzene, toluene, ethylbenzene, and xylenes (BTEX) constituents. Diesel probably comprised the majority of released fuel.
