Purpose Of This Notice

The New Jersey Department of Environmental Protection (NJDEP) is issuing a Draft Decision Document for the 398 Olden Avenue site in Trenton, Mercer County. Although referred to as the 398 Olden Avenue site, it actually consists of two former gas stations located at 398 and 302 North Olden Avenue. Gasoline discharges while the facilities were in operation caused the soil and ground water to become contaminated with volatile organic compounds (VOCs) at levels above New Jersey’s cleanup standards. NJDEP excavated and removed the contaminated soil to the maximum extent possible in 2001.

The Draft Decision Document outlines the remedial approaches NJDEP considered to address the VOC contamination in the ground water at the site and identifies its preferred remedy. Based on the evaluation, NJDEP selected “Oxygen Releasing Compound (ORC) Slurry Injection” as the preferred remedy. This remedy would involve injecting oxygen-releasing compounds into the shallow aquifer to stimulate the indigenous microorganisms in the subsurface to degrade the VOCs. A detailed discussion of the remedial alternatives that were considered and the preferred remedy is presented in the Draft Decision Document, which is being made available for public review and comment.
