Since Wisconsin’s groundwater resources play a critical role in human health and the economy, it’s important that more private well owners test their wells on a regular basis. That’s one of the findings in the 2017 annual Groundwater Coordinating Council report. Nearly three-quarters of Wisconsin residents rely on groundwater as the primary source for their drinking water. “Unlike public water systems, protection and maintenance of private wells is largely the responsibility of homeowners,” said Pat Stevens, Environmental Management Division administrator for the Department of Natural Resources and council chairman. “We recommend that private well owners test their water at least once a year for coliform and E. coli bacteria, important indicators of health risk.”
The 2017 report notes the steps taken to protect groundwater from contamination and helps the public better understand the sources and distribution of naturally occurring contaminants in groundwater. It also highlights the need for ongoing research into the factors that affect groundwater supplies and helps identify next steps to protect and preserve our valuable groundwater resources.
The Groundwater Coordinating Council was formed in 1984 to help state agencies coordinate activities and exchange information on groundwater. For more information, visit DNR.wi.gov and search “Groundwater Coordinating Council.”
