WILMINGTON, N.C. — A North Carolina man’s federal lawsuit contends chemical-makers for years released little-understood compounds into the drinking water for hundreds of thousands, hurting property values while the companies profited.

Wilmington resident Brent Nix this week filed a federal lawsuit against The Chemours Co. and DuPont. He’s seeking compensation for lost property values and possible health problems. Nix wants the lawsuit to include more than 200,000 people served by a Wilmington water utility as well as others in the region who consumed household water.

A Chemours spokesman did not respond Friday to an opportunity to comment.

The Wilmington, Delaware-based company has released the chemical GenX and other products into the Cape Fear River from its factory about 100 miles (161 kilometers) north of Wilmington. DuPont spun off Chemours two years ago.
