New Rules Regarding Groundwater Virus Treatment

Later this year, rules will go into effect that require disinfection of water by all municipal water systems in Wisconsin. This will increase protection for any state residents who’s drinking water comes from groundwater. These rules are based on a discovery highlighted in the 2010 Groundwater Coordinating Council Report that showed viruses are able to travel through layers of rock and soil, which was previously thought of as an adequate filtration system. The Groundwater Coordinating Council (GCC) is responsible for identifying areas where research is needed, reviewing research proposals, and publicizing research findings.

In addition to assessing water quality, the 2010 GCC Report also “described recent research on arsenic treatment, the effects of nitrates on stream invertebrates, the occurrence of mercury in wetlands, extreme precipitation events and developing new tools for investigating fecal contamination” (WDNR Release).

Wisconsin’s Water Library offers reading lists for the following related topics: Arsenic in Groundwater, Drinking Water Quality, Protecting our Wetlands, Understanding & Protecting Groundwater and Wastewater Treatment.
