Lincoln Park, New Jersey
The CP Environmental Group (CPEG) team was hired to perform environmental, asbestos, and geotechnical services in support of the redevelopment of a 1.75 acre site consisting of the former Burack Chevrolet and Oldsmobile dealership into a retail pharmacy. The Burack dealership included an automobile showroom, repair shop, body shop with spray booth and a car wash. A portion of the dealership had been a retail gasoline service station during the 1930s and 1940s.
Groundwater impacted with tetrachlorethene (PCE) and trichlorethene (TCE) was identified during assessment activities. During redevelopment of the site into a retail pharmacy a total of fourteen underground storage tanks (USTs), seven hydraulic lifts and an oil/water separator were removed. Approximately 1,370 tons of petroleum impacted soil was removed from the site during the UST removal activities for two areas of concern, totaling approximately 6,260 square feet.
Groundwater impacts (PCE & TCE) were allowed to degrade under natural conditions using monitored natural attenuation utilizing quarterly groundwater sampling (seven events conducted) until two successive quarters were documented with no exceedences of New Jersey Department of Environmental Protection (NJDEP) ground water quality criteria (GWQC) of the parameters monitored.
CPEG prepared a Remedial Action Report for the site in accordance with NJDEP’s regulations (NJAC 7:26) which was subsequently approved. NJDEP has granted No Further Action status for the site.
Also in support of site redevelopment, CPEG provided additional services including the geotechnical subsurface investigation, and asbestos survey at the previous site structures in addition to the remedial investigation and environmental site closure to streamline the site development process.
Total cost of project: $320,600

Soil remedial activities were conducted concurrent with demolition and construction activities to facilitate the site redevelopment schedule. Approximately 8,000 tons of soil were excavated and segregated, 1,370 tons of petroleum impacted soil were disposed of off-site and 6,630 tons of soil were reused on-site as fill, saving the client an estimated $250,000 in disposal costs. This project was successfully completed in the required time frame only by outstanding teamwork involving CPEG working closely with the private developer, pharmacy chain (purchaser), real estate investment trust group, New Jersey Department of Environmental Protection (DEP), attorneys and contractors. CPEG achieved site closure with more than $28,000 of the approved budget remaining (unused)
