About organic fluorine compounds

Some newspapers and other media have reported on organic fluorine compounds in tap water.

Tap water in Inagi City is currently supplied with water purified at the Higashimurayama Water Purification Plant.
The Higashimurayama Water Purification Plant is managed by the Tokyo Metropolitan Government, and regular inspections are also carried out for organic fluorine compounds.
Test results to date show that this is well below the government's provisional target for water quality management (50 nanograms per liter for PFOS and PFOA combined, 1/1 billion for nano), and does not pose a health risk. .
In addition, in Inagi City, from April 1, 2012, all water supply businesses have been transferred to the Tokyo Metropolitan Government.
