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.
Problems/Comments
On 7/1/2009 a petroleum release was discovered from an underground storage tank (UST) storing home heating oil (#2 diesel). The source of the release was determined to be a faulty fuel return line. The UST was subsequently removed, but the excavation of contaminated soil was limited laterally by the building foundation and vertically by the presence of groundwater at approximately 6 feet below ground surface. Petroleum constituents remain in soil and groundwater.
