At 20:30 on January 27, 2022, "chloric acid" was detected at a concentration exceeding the national standard of water quality (0.6 mg/L) in tap water collected at 19:30 at the Takatsuka Reservoir (Izumi Ward) sent from Kosuzume Purifiction Plant at 19:30 on January 27, 2022. This concentration is below the concentration (※ subacute reference value: 3 mg / L), which is considered to have no effect on health even if a child continues to drink for one month, and it 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.
