The level found at Kipapa Acres ranged from 0.0026 to 0.0034, which are above the new advisory level.

“As we learn more about PFAS and possible risk to health, it remains a priority to ensure that the public is aware of these contaminants in drinking water,” said Dr. Diana Felton, State Toxicologist. “While these detections do not pose an acute risk to public health, we continue to work with EPA and other stakeholders to reduce PFAS exposures and establish enforceable PFAS limits that protect public health.”

The EPA said PFAS are fluorinated organic chemicals used in furniture fabric, cookware, carpets clothing and paper food packaging that are waterproof, stain-resistant or non-stick. They are also in firefighting foam.
