Section Env-Ws 308.04 - Goals and Policy for Point-of-Use Treatment(a) POU treatment shall not be approved for contaminants that volatilize easily such as hydrogen sulfide or volatile organic compounds (VOCs), nor for contaminants that cause staining or pipe deposits such as iron, manganese, and hardness.(b) POU treatment shall be an alternate to centralized treatment to achieve compliance with the MCL requirements specified in Env-Ws 310 through 315. POU treatment shall be most appropriate for very small public water systems having contaminants that are difficult to treat or difficult to dispose of, or having a pump station that is inadequately sized for full scale treatment.(d) The department shall not approve a POU concept for an existing community water system unless the system evaluates interconnecting to another compliant water system and the availability of another water supply source(s) and determines that neither option is feasible.(e) A POU concept shall only be acceptable for contaminant concentrations of not more than 5 times the MCL.(f) The goal of Env-Ws 308.03 through Env-Ws 308.10 shall be to ensure that a POU treatment concept achieves the same level of health protection as would be achieved with central treatment.N.H.
