Webinar: Fracking with PFAS in Colorado February 2, 2022

A new report by Physicians for Social Responsibility (PSR) presents previously unpublicized evidence that energy firms have used a class of extremely toxic chemicals known as PFAS in Colorado oil and gas wells since at least 2008. Furthermore, Colorado law allows oil and gas companies to withhold fracking chemical identities from the public and from regulators by claiming them as “trade secrets.” As the report documents, companies have utilized that provision thousands of times, preventing the public from knowing how widely PFAS – or other toxic chemicals – have been used in oil and gas wells and raising concerns that Coloradans are unknowingly exposed to dangerous hazardous substances.
