The U.S. Environmental Protection Agency (EPA) has issued a rule enforcing maximum allowable levels of per- and polyfluoroalkyl substances (PFAS) in drinking water.

The directive, announced on April 10, 2024, sets non-negotiable maximum contamination levels (MCLs) for five PFAS compounds. The regulation affects public water systems nationwide, including the water system of the City of Dallas, following the conclusion of a local water sampling program.

PFAS are synthetic chemicals used in numerous household products and industrial processes, such as firefighting foam, non-stick cookware, creams, cosmetics, textiles, and pharmaceuticals. While some compounds have been phased out due to health and environmental concerns, numerous PFAS are still in active use today.

The five regulated compounds include PFOA, PFOS, PFHxS, PFNA, and HFPO-DA. For two compounds, PFOS and PFOA, the EPA has determined that no level of exposure is safe.

The new rule necessitates all Public Water Systems to monitor for these compounds, and if any violations of the maximum levels are detected, systems are required to implement solutions by 2029. The rule also introduces a Hazard Index MCL for water containing mixtures of two or more PFAS, considering the combined health risks from these mixtures.

The Dallas Water Utilities (DWU) has completed its first round of monitoring, collecting samples from its three treatment plants. Initial results suggest that the expected PFAS levels in DWU’s drinking water are in compliance with the new regulations. The DWU will include these results in its Consumer Confidence Report, well before the regulatory timeline of 2027.

The DWU is also proactively incorporating PFAS monitoring into the source water sampling program, investigating potential PFAS sources, exploring viable treatment technologies, and researching strategies to reduce PFAS levels.

Committed to providing superior drinking water services, DWU’s system is rated as a Superior Water System by the Texas Commission on Environmental Quality. The utility will continue PFAS monitoring for the targeted five compounds and substances included in the Hazard Index, in compliance with current and future EPA regulations.
