How Chemical Companies Avoid Paying for Pollution

DuPont factories pumped dangerous substances into the environment. The company and its offspring have gone to great lengths to dodge responsibility.

FAYETTEVILLE, N.C. — One humid day this summer, Brian Long, a senior executive at the chemical company Chemours, took a reporter on a tour of the Fayetteville Works factory.

Mr. Long showed off the plant’s new antipollution technologies, designed to stop a chemical called GenX from pouring into the Cape Fear River, escaping into the air and seeping into the ground water.

There was a new high-tech filtration system. And a new thermal oxidizer, which heats waste to 2,000 degrees. And an underground wall — still under construction — to keep the chemicals out of the river. And more.
