Japanese officials have removed the pollution water sources in Zhajin.During the official water quality survey in 2020, PFOA was found in groundwater, and the content was 110 times that of the tentative permit standards of 50 mm micro grams per liter.In 2022, the official was still detected in the local irrigation channel to detect 6,500 mgs per liter.
The local government has called on citizens not to drink well water, and also ordered the factory to make necessary rectification measures.
