More about cleanup

Site Description

The site operated as a bulk fuel facility which included aboveground storage tanks (ASTs), a heating oil underground storage tank (UST), an oil/water separator UST, and a waste oil AST. Gasoline and diesel were released to the soil and groundwater due to Site operations. The property currently operates as a fertilizer storage facility.

Several investigations and interim cleanup actions occurred between 1989 and 2020. The investigations identified areas of soil and groundwater contamination. Contaminated soil was removed during interim cleanup actions. A fluid was injected to aid the remediation of the remaining soil and groundwater contamination in 2020. Groundwater now meets the site cleanup levels.
