EPA Introduces New PFAS Drinking Water Limits; Irving Prepares for Compliance

Irving, Texas. July 25, 2024 –

In April 2024, the Biden-Harris administration issued the first Environmental Protection Agency (EPA) standards setting new drinking water limits on chemicals called PFAS, or per- and polyfluoroalkyl substances. Over the next three years, public water systems across the nation must test, monitor, and report levels of PFAS in drinking water. If levels exceed the federal standards, systems must implement solutions to reduce PFAS in drinking water within five years.

Also known as "forever chemicals" due to their resistance to breaking down in the environment, PFAS are present in numerous products used in households every day. These chemicals do not naturally occur in drinking water but are released upon contact with water and do not degrade. Consequently, PFAS enters water systems through contact with nonstick and water-repellent items such as cookware and clothing, necessitating ongoing efforts to remove the chemicals from products.

PFAS levels are measured in parts per trillion, which is equal to one drop in 20 Olympic-sized pools. Despite their widespread existence in the environment, recent measurements in Irving demonstrate only trace amounts of PFAS.

Irving’s drinking water is treated by Dallas Water Utilities (DWU), and Irving’s Water Utilities staff works closely with DWU to ensure compliance with regulatory standards. There is federal funding available to help implement the testing and treatment; however, the new requirements will result in higher costs for advanced treatment methods, which will likely increase municipal water rates.

Although cities have until 2027 to gather data, Irving has completed PFAS testing and will continue to work with DWU to ensure drinking water meets mandated levels by 2029. Residents can access comprehensive drinking water data and information in the annual Water Quality Report at CityofIrving.org/Water-Report.
