The Wisconsin Ground Water Association (WGWA) is a non-profit volunteer organization whose purpose is to advance the understanding of ground water in Wisconsin.  WGWA has sponsored numerous statewide technical conferences featuring hundreds of speakers from Wisconsin and other states discussing topics of local, regional, and national significance.  Our objectives include promoting an understanding of scientific, technical, legal and public policy aspects of ground water; providing a forum for exchange of information, disseminate information to governments, schools, and civic professional organizations, and educate the general public regarding ground-water resources; and  promote professional awareness and technical skills among ground-water professionals.

  • Groundwater Guardian is a national program which connects and recognizes communities that take action to protect groundwater and educate the public about groundwater. It is sponsored by the Groundwater Foundation in Lincoln, Nebraska. Groundwater supplies drinking water for 95% of Wisconsin communities, Denise Kilkenny-Tittle said. But we're seeing increasing problems for some communities with groundwater quality. In addition, some communities are faced with declining water levels in their wells. So it's natural that people would want to come together to help protect groundwater, and the Groundwater Guardian program is an easy and organized way to do that.
