CODE provided high hazard and contaminated soil remediation services at the 40-acre Chemsol Superfund Site in Piscataway, NJ. The site was located close to Route 287, one of Central New Jersey’s major traffic arteries, and in relative proximity to public residences, several shopping malls, and numerous small commercial enterprises. An apartment complex and several dwellings were located within several hundred yards of the site. To minimize truck traffic and enhance site/public safety, CODE constructed special access roads and participated in community outreach programs.

SITE REMEDIATION:

CODE excavated ~60,000 tons of PCB/TSCA/RCRA contaminated soil. CODE also remediated an adjacent wetlands areas, dismantled/replaced existing piping for the site's groundwater recovery system, and treated 1,000,000+ gallons of lead-contaminated water in an on-site treatment system.

As part of the remedial action, CODE constructed two stream diversions and installed 40 feet of HDPE pipe with flair end fittings under the haul road for complete renovated surface drainage.

CODE also restored remediated wetland areas. Following the wetlands restoration the 28-acre site was capped with clean fill and topsoil.

HIGH HAZARD WASTE HANDLING:

An area previously identified as containing buried drums and lab pack materials was found to contain acutely hazardous substances. CODE mobilized its high hazard response team to handle this phase of the project. Representatives from involved agencies (EPA, USACE, and NJDEP) were present at the site during critical phases of the project to monitor CODE’s operations. The work was completed safely to the satisfaction of all involved parties.
