"Colorado has become the first US state to ban per- and polyfluoroalkyl substances (PFAS) in products used in drilling for oil and gas.
A measure signed by Gov. Jared Polis (D) June 3 prohibits the sale or distribution of fluids used in hydraulic fracturing, drilling fluids, and proppants—materials injected to keep geologic fractures open—that contain PFAS. The law also bans a number of other items when they contain intentionally added PFAS: cosmetics; food packaging; carpets and rugs; upholstered furniture; and products, including car seats, designed for children under age 12.
The ban takes effect Jan. 1, 2024.
PFAS are highly persistent industrial chemicals that are widely used in a variety of applications to provide stain and water resistance. These sturdy molecules also resist heat and other adverse conditions without breaking down. Some PFAS are toxic, linked to liver and kidney damage."
