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.

- The Wisconsin Geological and Natural History Survey has created 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: www.WisconsinGeologicalSurvey.org and read from our "Stories from the Field" for more information.
- The U.S. Geological Survey would like to announce a new Web site that may be of interest to you. They have just finished the most comprehensive Web site about "The Water Cycle" anywhere.
