Thornton filed a lawsuit Monday [January 30, 2023] in South Carolina District Court against dozens of companies and people that produce PFAS, or “forever chemicals”, claiming the toxic substances contaminated the city’s water supply. Not only is Thornton suing a slate of high-profile companies, like 3M, DuPont and Chemours, it’s also suing 20 unnamed “entities or persons” that might have “permitted, caused and/or contributed” to the contamination of the city’s water. For decades the companies understood that PFAS, or perfluoroalkyl and polyfluoroalkyl substances, do not degrade naturally and were accumulating in people’s bodies, according to the lawsuit’s complaint…
Thornton officials announced in July that its water supply exceeded the EPA’s new – sharply reduced – limits for PFAS by more than 1,000 times. The city supplies water to about 160,000 people. At the time, Thornton’s water treatment and quality manager said the source of the chemicals weren’t immediately clear but that the city had stopped using some wells from which they drew water and began treating other water sources with new chemicals to draw out the toxic substances. Now city officials believe the contamination comes from firefighting foam used across the area for training and for actual fires, the lawsuit says. Thornton hired a consultant to help understand how best to clean the contamination. Cleanup and damage is expected to haunt the city “for many years to come,” the lawsuit says. The city is looking for money from the companies for the damage done to its property and for the cost of “investigating, remediating, and monitoring” its drinking water. While Thornton appears to be the first city in Colorado to sue PFAS manufacturers, its legal action follows a similar lawsuit filed nearly a year ago by Attorney General Phil Weiser.
