The groundwater quality study being conducted by the University of Wisconsin-Oshkosh across Door County could reveal significant changes from past evaluations. Professor Greg Kleinheinz says that the karst topography leads to shifting conditions on its own. Still, high water levels add more uncertainty to the mix, especially for wells near the shoreline.

The UW-Oshkosh study solicited participation from homeowners across the county last year, including sites from a broad geographic mix that includes northern Door County, which is most likely to be affected by the issues Kleinheinz raises.
