EPA Maintains PFOA and PFOS Limits, Offers Flexibility for Water Systems Compliance


Listen Later

The Environmental Protection Agency has announced it will maintain the current limits for PFOA and PFOS, two major types of "forever chemicals," in drinking water while providing additional flexibility for implementation. EPA Administrator Lee Zeldin stated they will uphold nationwide standards protecting Americans from these chemicals while offering additional time for water systems to achieve compliance. This approach aims to support water utilities across the country, particularly small systems in rural communities, as they work to address these contaminants.

Water utilities had previously challenged the EPA's regulations, arguing that treatment systems for removing these chemicals were expensive and would increase costs for customers. The EPA's recent decision aligns with some arguments made in the utilities' lawsuit, including granting a two-year extension for compliance. However, the agency plans to withdraw limits for certain newer types of PFAS chemicals. Currently, nearly 12 percent of U.S. water utilities exceed the Biden administration's established limits for these substances.

Environmental advocates have expressed concerns about the rollback, with the Natural Resources Defense Council calling the move illegal, citing provisions in the Safe Water Drinking Act that prevent new rules from being less stringent than previous ones.

Looking ahead, the Global Water Summit, a premier event for the water industry, took place from April 21 to 23 in Madrid, Spain.
