An understanding of the fate of...
Plan for an integrated, long-term water-monitoring network for Wisconsin
Prepared by the Team for Evaluating the Wisconsin Water-Monitoring Network
1998, Fact Sheet 048-98
Wisconsin's water-monitoring network is in danger of losing critical ground-water, surface-water, and water-quality monitoring stations. Since 1995, the ground-water network has decreased by 43 observation wells, the surface-water network by 7 stations, and the surface-water- quality network by 30 stations. Reductions in Wisconsin's water-monitoring network could cause serious risk to...
