New Jersey Superfund Site - TPEC staff conducted the design of the groundwater extraction and injection system.
TPEC staff also designed and provided construction oversight for a 600-gpm capacity wastewater treatment plant and a 500-cfm soil vapor extraction system for the site soil and groundwater remediation of the SJCC/GSC superfund sites.
The wastewater treatment system included iron and manganese precipitation, air stripping, granular activated carbon polishing, and pH adjustment prior to re-injecting the treated water up-gradient of the groundwater plume.
