Excess of water quality standards in tap water

At 20:30 on January 27, 2022 (Thursday), at 19:30 at the Takatsuka Reservoir (Izumi Ward) sent from Kosuzume Purifiction Plant, "chloric acid" was detected at a concentration exceeding the national standard (0.6 mg/L) (0.79 mg/L). This concentration is lower than the concentration (※ subacute reference value: 3mg / L), which is said to have no effect on health even if children continue drinking for one month, and drinking does not affect health. We believe that the concentration of chloric acid will decrease in the future, but if you are worried, please refrain from drinking just in case.
