“Chemours Co. has been asked by federal regulators to test public and private drinking water supplies in West Virginia and Ohio for a chemical it uses to make products including Teflon.

A Jan. 11 letter from the Environmental Protection Agency, seen by Bloomberg News, asks for the tests to begin no later than March 31 because the agency is “concerned” that water sources may be contaminated with a chemical known as GenX. The tests will be conducted in communities on both sides of the Ohio River near Chemours’s Parkersburg, West Virginia, plant, also known as Washington Works.

The letter cites prior testing and similar issues near the company’s plant in Fayetteville, North Carolina, where Chemours is supplying bottled water to some residents.

The new tests are another chapter in a long saga of regulatory and legal inquiries into chemicals made by Chemours that are used to produce non-stick, grease-proof and waterproof products. Chemours, spun off from DuPont Co. in 2015, did not immediately respond to a request for comment…

The EPA’s concern is “based in part upon the fact that GenX has been detected in three on-site production wells and one on-site drinking water well, at the Washington Works facility,” the agency said in the Jan. 11 letter. It seeks testing of raw and treated water to see if treatment systems are adequately filtering out the chemical, according to the letter.”
