Page 1 of 1 CITY KALISPELL To: Doug Russell, City Manager From: Susie Turner, Public Works Director Re: Emerging Issues Regarding Drinking Water Standards Meeting Date: November 14, 2022 Background: Kalispell operates a Community Public Water Supply and is required to follow the drinking water rules and regulations set forth by the State of Montana Department of Environmental Quality (DEQ) and the Environmental Protection Agency (EPA). The Safe Drinking Water Act (SDWA) was passed in 1974 to protect public health, by regulating public water systems and requires the EPA to establish and enforce standards that public drinking water systems must follow. SDWA authorizes the United States Environmental Protection Agency (US EPA) to set national health -based standards for drinking water to protect against both naturally occurring and man- made contaminants that may be found in drinking water. The legal limit for a contaminant via the regulation reflects the level that protects human health and what water systems can achieve using the best available technology. EPA rules also set water -testing schedules/ methods and public notifications that water systems must follow. EPA delegates primary enforcement responsibility (also called primacy) for public water systems in Montana to DEQ. Below are the drinking water rules grouped by contaminant type that Kalispell is required to follow to serve a community from groundwater sources. Contaminant Type Regulation • Arsenic rule • Chemical contaminant rules • Lead and copper rule Chemical contaminants • Radionuclides rule • Nitrate/Nitrite rule • Variance and exemptions rule • Ground water rule • Chlorination rule Microbial contaminants • Stage 1 and stage 2 disinfectant/disinfection byproducts rule • Total coliform rule and revised total coliform rule • Consumer confidence report rule Right -to -know rules 0 Public notification rule Meeting Discussion: To ensure public health is continually protected, the SDWA requires EPA to establish regulations for new contaminants, in addition to reviewing existing primary and secondary national drinking water regulations, and as appropriate, revises them to improve public health protection. In 2021/2022, EPA and DEQ have heightened their drinking water contamination reviews, publications, and potential regulatory updates for manganese, lead and copper, and per - and polyfluoroalkyl substances (PFAS). Additionally, per- and polyfluoroalkyl substances (PFAS) may also affect the regulatory requirements established by the EPA and DEQ for the City's wastewater and stormwater discharge permits. Given Council's recent legislative platform adoption regarding Environmental Quality, staff will provide a summary of the contaminants and rules currently being reviewed by EPA and DEQ and how the potential regulatory requirement of these contaminants might affect future utility management and the potential economic impacts. 2
