The Chemical Control Corporation (CCC) site is a 2-acre area next to the Elizabeth River in New Jersey. From 1970 to 1978, a hazardous waste storage, treatment and disposal facility operated on site. Discharge and waste storage violations led to on-site soil contamination. Cleanup activities have been completed. Long-term monitoring is ongoing.
What Has Been Done to Clean Up the Site?
EPA performed numerous intermediate actions at the Chemical Control Corp. site which greatly reduced the potential for exposure to hazardous materials and eliminated sources of contamination.
Construction of the final remedy for the site was completed in December 1993. The final remedy involved the construction of a slurry wall around the site which is anchored into the underlying clay layer. Approximately 25,000 cubic yards (40,000 tons) of contaminated soil was solidified with cement, within the slurry wall. The solidified soils were graded and later covered with clean gravel. An 8-foot tall chain-linked fence was installed around the site to restrict unauthorized access. Contamination later found in a narrow area along the bank of the Elizabeth River, next to the slurry wall was later treated, using bio-remediation. The application reduced but did not eliminate all the contamination in this area.
EPA has conducted four five-year reviews at the site. These reviews evaluate the performance of the remedy to ensure that the remedy protects public health and the environment and that it is functioning as intended by its design. The most recent review in 2014, concluded that response actions at the site are in accordance with the remedy selected by EPA and that the remedy continues to be protective of human health and the environment.
What Is the Current Site Status?
The site is now being used by the owner as a staging area, the materials staged at the site and the current site use does not pose a risk to the integrity of the remedy.
