basic information

PFAS stands for perfluoroalkyl and polyfluoroalkyl substances. Among PFAS, three types—perfluorooctane sulfonic acid (PFOS), perfluorooctanoic acid (PFOA), and perfluorohexane sulfonic acid (PFHxS)—have established regulatory and target values in domestic drinking water and environmental water. The target value for PFOS and PFOA is set at a combined 50 ng/L (as of March 2025) under the water quality management target setting items of the Water Supply Act. Additionally, PFHxS is classified as a subject for further consideration. PFOS and PFOA are also designated as items to be monitored for the protection of human health related to water quality pollution, with a guideline value (provisional) set at a combined 0.00005 mg/L. Furthermore, PFOS, PFOA, and PFHxS are included as measurement targets in the provisional measurement methods for soil as notified by the Ministry of the Environment.
