“If we’re thinking about how we want to manage or protect groundwater resources in the future, we really need to be thinking about what’s happening on the land surface. And if you look at Wisconsin, greater than 90% of the land is, really, rural land,” said Michael Cardiff, a professor in the department of geoscience at UW-Madison. “Rural water users are probably most connected to the largest area of land in Wisconsin, and could probably tell us about what sort of concerns they’re seeing.”
