Pledger Creek Remediation

History & Location

The Pledger Creek site is in Mannington Township, Salem County, New Jersey. The scope of work included remediation in an area of the inactive on-site industrial landfill, dredging contaminated sediments from Northern Pledger Creek (NPC), dredging Central Pledger Creek (CPC), and dredging Southern Pledger Creek (SPC). The creek reaches which required sediment dredging are west, north, and adjacent to the facility. The primary contaminants of concern were PCBs and mercury.
