The Board of Water Supply (BWS) on Oahu reported PFAS contamination above the 4 ng/L MCL in several drinking water wells. Samples from May 2026 showed PFOS at 5.0 ng/L in Kaamilo Wells. Additionally, the Navy Aiea-Halawa Shaft registered PFOA at 5.09 ng/L and PFOS at 6.78 ng/L in June 2024. These findings prompted a formal request to expand the Red Hill monitoring well network.
