Site Remediation

Environmental Assessment Reports, New Jersey Prepared more than 100 site environmental assessment reports, including preliminary assessments, site investigation work plans, site investigation reports, remedial investigation work plans, remedial investigation reports, remedial action work plans, and remedial action reports, for submittal to both regulatory agencies and private companies. These efforts frequently included such tasks as performing public notification and outreach, obtaining remedial action permits, establishing deed notices, and establishing and/or terminating classification exception areas.
Direct Oversight Program, New Jersey Prepared submissions to NJDEP under its direct oversight program, including public participation plans, annual remediation fee forms, remediation trust funds, and negotiations for the administrative consent orders, in addition to preliminary assessments, site investigation reports, and remedial investigation reports.
Industrial Property, New Jersey Managed site investigation and remediation of an industrial property with petroleum impacts exceeding the free product limit and PCBs. These issues triggered the requirements of TSCA and required federal as well as state remediation and reporting obligations.
Fill Management, Pennsylvania Completed several fill management projects during construction and redevelopment in accordance with the PADEP management of fill policy, including selection of appropriate PADEP maximum contaminant levels (MCLs), clean and regulated fill determinations, and waste disposal in accordance with the PADEP policy regarding use of reclamation fill at active noncoal sites.
Closed Industrial Landfill, Edison, New Jersey Managed a high-volume groundwater pumping test. Designed the customized equipment used to complete the test, which exceeded 100 gallons per minute (gpm) and maintained 40 gpm over a 24-hour period. Project also involved performing a step-drawdown test in preparation for the 24-hour pump test to accurately predict the maximum yield of the aquifer (40 gpm).
Residential Fuel Oil System, Toms River, New Jersey Completed an innovative mobile hydrocarbon evaluation using a water-drive method analysis to determine mobility of free-phase light nonaqueous-phase liquid (LNAPL). This evaluation included overseeing the collection of undisturbed cores, the freezing of these cores in dry ice, and their shipment to Texas for analysis. The conclusion of the evaluation was that the LNAPL was not mobile; this evaluation was used as a line of evidence to close the case.
Closed Sanitary Landfill, Elizabeth, New Jersey Performed analytical evaluation of a stagnant wetland mitigation project experiencing vegetative cover loss. Project included designing and implementing innovative techniques that ultimately achieved a 100 percent increase in vegetative cover within 1 year.
