Remediation Case Study


As part of a real estate transaction for a multi-building commercial property in Princeton Junction, New Jersey, Quick Environmental was contracted to close a total of seven out of service, No. 2 heating oil and gasoline underground storage tanks (UST’s).

The tanks ranged in size from 550 to 10,000 gallons in size. Because two of the tanks were gasoline tanks and the aggregate volume of the oil tanks was over 2,000 gallons, they were regulated by the NJDEP. Hence, the project required the oversight of a Licensed Site Remediation Professional (LSRP).

Upon removal of the tank systems, five of the seven tanks were determined to have leaked. Quick Environmental’s expertise and knowledge of NJDEP regulations resulted in having to remediate only two of the tank contamination areas. Site investigation sampling was conducted in the remaining areas in an effort to obtain compliant samples. The results of the investigation showed that there was only minimal contamination in the other areas and the DEP allowed the soil to remain in place.

Delineation methods were implemented prior to conducting soil removal in the remaining two tank areas to more accurately determine the contaminant area. This minimized the amount of soil that had to be removed and kept the project within budget. The end result was closure of the project through the issuance of a Response Action Outcome (RAO) document by the LSRP. The transaction was then able to proceed and the property was sold shortly thereafter.
