EPA Superfund Site

PARRIS ISLAND MARINE CORPS RECRUIT DEPOT

SC | EPA ID SC6170022762

About this site’s exposure pathways: As of August 2023, there is insufficient information to determine if Human Exposure is under control at the Parris Island Marine Corps Recruit Depot Superfund Site for Site 45. At Site 45 groundwater contaminated with volatile organic compounds is entering the storm water system pipes and manholes where it travels down the pipes to the outfall which empties into the marsh. There is insufficient data to determine if workers who may enter the manholes would be exposed to unacceptable levels of contamination in the air and water. The Navy has agreed to seal the storm water drains and/or manholes to prevent intrusion of contaminated groundwater from Site 45. Once sealed and flushed, the manholes and pipes would no longer contain contaminated groundwater from Site 45. Therefore, there would be no need for additional air data or monitoring. The Site 45 ROD requiring this remedial action is complete. The RD and RAWP are in progress. The remedy component sealing the storm sewers will need to be completed before status of the HE indicator can be reconsidered. There are approximately 18 sites remaining at MCRD where HE may not be under control or insufficient data exists to make a determination. Progress has been made at a significant number of these potential sites. However, they may continue to impact the EI determination even after Site 45 is remediated.
