Does the home water treatment system I have work to remove PFAS? What types of treatment address PFAS in drinking water?

Viable treatment options for PFAS reduction include granular activated carbon (GAC) and point of use reverse osmosis (RO). Treatment effectiveness is dependent on treatment sizing, contact time, and how well the device is maintained. For specific devices, it may be best to check with the manufacturer of your treatment device.

To find products certified to reduce PFOA and PFOS, by the National Sanitation Foundation (NSF) please refer to: NSFProtocol P473 Drinking Water Treatment – PFOA & PFOS. There are currently no treatment devices certified to reduce PFAS other than PFOA and PFOS. For more information please refer to the DPH Per- and Polyfluoroalkyl (PFAS) Detections in Private Well Water guidance
