Water safety confirmed in all wells surveyed in selected Fukushima areas

Screenings for radioactive contamination conducted by the Fukushima prefectural government at 185 selected water wells in the Hamadori and Nakadori regions of the prefecture have found that all of them are safe for drinking, measuring below the lower detection limit. The wells covered are located in 41 cities, towns and villages in the two regions, including evacuation areas designated after the Fukushima Daiichi nuclear power plant accident. The prefectural government believes the results show radioactive substances have not permeated soil in the hot zones and that well water is safe to drink.
Restoration of water supply facilities has been delayed in both "areas being prepared for the lifting of the evacuation order" and "residence restriction areas." But the latest findings have made it possible to use well water as an alternative supply source in place of damaged waterworks.
Before conducting the screenings between October last year and March this year, the local government selected 200 wells for surveys, including 25 in nine municipalities that have evacuation areas. Of these, 15 wells were not screened because of inability to take water samples and other reasons. The prefectural
