WGF analyses primarily about ground water quantity, high capacity wells, and water use. Also see the agriculture category for WGF work on nitrates in ground water. This work is developed by WGF’s Water Resources and Environmental Rules Work Group.

Nitrates in Wisconsin Waters – A Wisconsin’s Green Fire Policy Analysis

While Wisconsin has among the finest freshwater resources in North America, an increasingly large number of Wisconsin communities, homes, schools, and businesses find their water sources unsafe to drink.

The total scope of the water quality crisis in Wisconsin today is much larger however than one community or one region. Wisconsin needs a drinking water solution equal to the magnitude of the problem. This paper lays out elements of that solution.

High Capacity Well Impacts on Wisconsin’s Lakes, Streams, and Wetlands

Revised June 3, 2020

Wells pump groundwater, which in Wisconsin is usually strongly connected to local lakes, streams, and wetlands. When groundwater is pumped, water levels in aquifers (the rock and soil that holds groundwater) drop, as do the levels of water in connected surface waters and the groundwater flows that support them. The effects of …
