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 groundwater professionals.

  • The Wisconsin Geological and Natural History Survey has a database of the porosity and density of Wisconsin aquifers and aquitards using core samples collected from drill holes around the state. We provide high-resolution images of the core taken from different depths and a table listing: formation name, lithology, depth, porosity, and density data for thirty (30) samples from six (6) different locations. Go to: and read from our "Stories from the Field" for more information.

  • WGWA has a private LinkedIn Group for members to be able to post discussions, join discussions that have already started, or post local events. Follow this link to request to join the group and check in often for news and events information.

  • The Wisconsin Department of Natural Resources has issued a revision to NR 140, Water Quality Standards. 15 new compounds have been added to the list, and revisions have been made to15 existing compounds. The link to the updated standard can be found HERE.

  • 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.
