The case against DuPont, which was settled in 2000, would reveal that the company had been using the property to dispose of sludge containing a chemical called perfluorooctanoic acid (often shortened to PFOA or C8), which was used in manufacturing Teflon. This chemical was entering the water supply.
The massive health study that followed, involving 69,000 people, would link the chemical to kidney and testicular cancer, thyroid disease, high cholesterol, pregnancy complications, and ulcerative colitis.
