“PITTSBURGH—In June, Colorado became the first state to ban the use of PFAS during oil and gas extraction — and now, in light of recent research finding the potential for widespread contamination, some are calling for a similar ban in Pennsylvania.
Last year it was revealed that PFAS (per- and polyfluoroalkyl substances), a group of more than 9,000 chemicals, have been used in oil and gas wells for decades. The chemicals, which are water- and grease-repellent, are sometimes used in fracking fluid to make the chemical mixture more stable and efficient in flushing oil and gas out of the ground at high pressure. PFAS may also be used during initial drilling and other phases of oil and gas extraction — not just fracking.
That’s about to change in Colorado: A new bill restricts PFAS in products like carpets and furniture, fabric treatments, cosmetics, food packaging and children’s products; and bars the use of PFAS in any type of oil and gas extraction, including fracking. The law will take effect on Jan. 1, 2024.
With a separate, related bill, Colorado also became the first state to require oil and gas companies to publicly disclose the complete list of chemicals used ‘downhole’ for all types of wells, and to certify that no PFAS were used during drilling or extraction.
Downhole chemicals include those used during drilling and other phases of operations. Most public disclosure laws in other states focus mainly on chemicals used in fracking wells, and most only require disclosure of chemicals used during extraction, ignoring the chemicals used during drilling or other operations.” …
