The Ridges Research Committee worked with researchers and students at UW-Green Bay on a study of water quality in the Sanctuary. The study’s primary goal was to gather baseline data on concentrations of heavy metals, nutrients, and minerals in the surface- and groundwater in the Sanctuary. This is especially important because several plant and animal species here are closely dependent upon good water quality for their survival. Water samples were taken periodically from small groundwater wells, and from springs and swales.
Results indicate that water quality of both the surface and groundwater at The Ridges is very good. Future studies will enable us to compare and assess any changes in our water quality.
