PFAS Regulations Projected to Impose Billions of Dollars of Compliance Costs on Drinking Water Systems
A recent report from the Congressional Budget Office (CBO) estimated that the costs to comply with anticipated drinking water standards for per- and polyfluoroalkyl substances (PFAS) are likely to exceed “several billion dollars.” The CBO analyzed Senate Bill 1507 which passed out of Senate Environment & Public Works Committee earlier this year. Senate Bill 1507 seeks to require U.S. EPA to promulgate drinking water standards for perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) and imposes monitoring requirements on drinking water systems. The bill could potentially impose fairly stringent requirements on more than 67,000 public water systems.
The CBO estimate comes on the heels of a recent New Hampshire court decision that put on hold New Hampshire’s newly promulgated groundwater standards setting a 12 part per trillion (ppt) limit on PFOA and 15 ppt limit on PFOS. The standards were challenged on the basis that New Hampshire’s Department of Environmental Services (DES) had not conducted an adequate cost-benefit analysis of the new regulatory standards. The court agreed that DES had not conducted the cost-benefit analysis required by New Hampshire statutes and therefore enjoined DES from enforcing the new groundwater standards until such time as the analysis is completed.
