Xylem mobile technology helps US water utilities achieve compliance with new PFAS rules

A new mobile treatment system from water technology company Xylem is enabling utilities to comply with the new regulation from the Environmental Protection Agency (EPA), which has established legally enforceable limits for certain per- and polyfluoroalkyl substances (PFAS) in drinking water.

The MitiGATOR mobile system can be deployed to allow utilities to begin reducing PFAS and other emerging contaminants on site. It can also be used to provide technology performance data to help utilities select a more permanent solution.

The system uses granular activated carbon or ion exchange resins in specially designed vessels to mitigate contaminants. With remote monitoring capabilities, the ability to connect directly to source water, and a flow rate of up to 1,000 gallons/min, the technology helps regulated entities comply with the new regulations.

“The EPA’s new national drinking water standard sets an enforceable limit on PFAS levels for the first time, and the implications for communities across the US are complex,” said Snehal Desai, Xylem senior vice-president, chief growth and innovation officer. “With more than 10 years of experience deploying PFAS solutions, our technology and experience can help water utilities navigate these requirements from initial assessment and emergency treatment through to long-term treatment solutions.”

The MitiGATOR mobile system can be configured for use at sites including municipal drinking water systems, drinking water wells, and surface water. Enclosed and temperature controlled, the system is said to be deployed in any season and withstand harsh environments. It can also be provided as stand-alone treatment for contaminated water, or as part of a fully integrated treatment system.

The EPA estimates that between 4,100 and 6,700 public water systems serving up to 105 million people will be required to take action to reduce PFAS above the regulatory standards. As a result, the new rules bring sweeping implications for water utilities that must reduce PFAS levels and meet new public disclosure requirements.
