Records Indicate Oil and Gas Firms Injected PFAS into More than 1,200 Wells Since 2012; EPA Approved Chemical for Oil and Gas Operations Despite PFAS Concerns

This report presents previously unpublicized evidence that major oil and gas companies, including ExxonMobil and Chevron, have used per- and polyfluoroalkyl substances (PFAS), or substances that could degrade into PFAS, in hydraulic fracturing (“fracking”) for oil and gas in more than 1,200 wells in six U.S. states.

Toxic in minuscule concentrations, these man-made chemicals accumulate inside the human body and do not break down in the environment – hence their nickname, “forever chemicals.” Various PFAS have been linked by the U.S. EPA to low infant birth weights, effects on the immune system, cancer, and hormone disruption.
