|Details:||A finished water sample collected 7/21/21 showed manganese at 0.661 mg/L which is above the 0.3 mg/L health advisory level considered acute for infants under 6 months. Water system issued an advisory 8/10/21 and sent a copy to OHA. Tap water should not be used to prepare bottles or food for infants under 6 months. The elderly and those with liver disease should also consider using an alternate source of water for drinking. Infants, the elderly, and those with liver disease should avoid food made with water (for example, soup). Do not boil water that you intend to drink (boiling can increase levels of manganese). The water system is currently in the process of switching over to a better well.
Update 06/03/2022: A finished water sample collected 4/13/22 showed manganese at 0.666 mg/L which is above the 0.3 mg/L health advisory level considered acute for infants under 6 months. Water system reissued advisory 6/3/22 and sent a copy to OHA.
Lifted 07/26/2022: A finished water sample collected from EP-A on 7/14/22 showed manganese at 0.152 mg/L which is below the 0.3 mg/L health advisory level. Water system has added another well and is blending sources to bring manganese levels down below the HAL. Therefore, advisory has been lifted and recommendations have been made to water system to continue to monitor the EP for manganese periodically to ensure results stay below the HAL (for example, monthly to start then quarterly if consistently below HAL), and continue to report results to OHA.
