Toxic Chemicals Detected in Rivers and Groundwater Across Japan

TOKYO, Apr 25 (News On Japan) - Organic fluorine compounds known as PFAS—suspected to be harmful to human health—have been detected at concentrations exceeding the national provisional target in rivers and groundwater at 242 sites across 22 prefectures, according to a government survey.

Among PFAS substances, two compounds in particular—PFOA and PFOS—are considered hazardous. Japan's Ministry of the Environment has set a provisional target of no more than 50 nanograms per liter for the combined concentration of these two chemicals in rivers and groundwater.

The ministry's fiscal 2023 survey, which examined 2,078 sites in 39 prefectures, revealed that 242 sites in 22 prefectures surpassed the government's target for PFOA and PFOS concentrations.

The highest level was found in groundwater in Settsu City, Osaka Prefecture, measuring 26,000 nanograms per liter—520 times the national target.

The ministry has urged local authorities to ensure that water from these sites is not used for drinking purposes.
