PFAS (perfluoroalkyl and polyfluoroalkyl substances) have been detected in water samples collected at the Haleakal\u0101 Park Rain Shed Chlorinator of the Haleakal\u0101 National Park water system (Public Water System HI0000222), which serves areas of Haleakal\u0101 National Park on Maui.<\/p>\n

\"\"<\/p>\n

The detection of PFAS at the Haleakal\u0101 Park Rain Shed Chlorinator was confirmed through multiple samples collected between Nov. 14, 2023, and March 31, 2026. Haleakal\u0101 National Park notified the Hawai\u2018i Department of Health of the initial detection on May 1, 2026. The detected PFAS levels are listed below.<\/p>\n

The concentrations of PFAS detected at the Haleakal\u0101 Park Rain Shed Chlorinator of the Haleakal\u0101 water system are not expected to pose significant public health risk.<\/p>\n

While perfluorobutanoic acid is not currently regulated by the US Environmental Protection Agency, DOH has established Environmental Action Levels for PFBA of 15 \u00b5g\/l in surface water that may be used as a drinking water source. EALs are risk-based screening tools used to determine when contamination in soil, water or air may require further investigation or cleanup to protect human health and the environment. The detections at the Haleakal\u0101 Park Rain Shed Chlorinator are well below the surface water EAL.<\/p>\n

According to the EPA, PFAS are fluorinated organic chemicals that have been used since the 1940s in consumer products such as carpets, clothing, furniture fabrics, food packaging and cookware designed to be waterproof, stain-resistant or nonstick. PFAS are also used in firefighting foam and various industrial applications. EPA notes that some PFAS compounds have been associated with potential health effects following sufficient exposure over time.<\/p>\n
