Davenport explains, "PFOA and PFOS are no longer manufactured in the United States but can be imported in the form of consumer goods such as carpet, leather and apparel, textiles, paper and packaging as well as in coatings, rubber and plastics; the agency said. . . . Industries that use the chemicals have said that the designation is too expensive and would lead to litigation that could impose new costs on businesses and communities and slow the cleanup of chemicals."
The fact remains that all PFAS are harmful to humans. The compounds "degrade very slowly and can accumulate in the body and the environment. Exposure to PFAS has been associated with metabolic disorders, decreased fertility in women, developmental delays in children and increased risk of some prostate, kidney and testicular cancers, according to the EPA," Davenport writes. "Under the new rule, companies are required to immediately report releases of PFOA and PFOS that meet or exceed one pound within a 24-hour period to the National Response Center, and also to state, tribal, and local emergency responders."
As far as cleaning up PFAS -- it isn't simple or cheap. Even after PFAS are removed from water, there is no easy way to dispose of the products produced by the removal process. "Studies have shown that PFAS can be broken down with energy-intensive technologies," reports Fast Company. "But this comes with steep costs. Incinerators must reach over 1,800 degrees Fahrenheit (1,000 Celsius) to destroy PFAS, and the possibility of creating potentially harmful byproducts is not yet well understood."
