This month Colorado became the first state to ban the use of PFAS in the extraction of oil and gas.
While there has been widespread outcry about PFAS (per- and polyfluoroalkyl substances) in consumer goods — such as stain- and water-resistant clothing, nonstick pots and pans, firefighting foam, carpets and furniture — the oil and gas industry could be a major and under-appreciated source of soil and groundwater contamination.
Last summer an investigation by the advocacy group Physicians for Social Responsibility revealed that the chemicals are often used in the fluids used to extract oil and gas from deep in the ground during fracking. The chemicals, which are extremely water-repellent, are used in fracking fluid to make the chemical mixture more stable and more efficiently flush oil and gas out of the ground at high pressure.
