Wilmington (DuPont Corporate HQ), Delaware

DuPont Chambers Works facility’s relative location to Wilmington, DE

Though New Castle County has attributed its PFAS contamination to firefighting foam used at a local airport, Wilmington’s extremely high PFOS levels may be attributed to DuPont’s Chambers Work’s facility, located directly across the Delaware River.

The Chambers Works facility has an on-site waste water treatment plant where it treats wastewater generated from Chambers Works and other U.S. DuPont sites. The waste water treatment plant is located in the northern section of the Chambers Works facility, near Carneys Point.

The treated water is discharged into the Delaware River, into the town of Wilmington, Delaware.

DuPont Chamber Works has been fined many times by the NJDEP for various violations including unauthorized hazardous waste discharge. (source) (source) (source)
