Maureen Muldoon, a geology professor from the University of Wisconsin-Oshkosh, presented data on the source and method of water contamination in Kewaunee County during a meeting at the Expo Hall at the Kewaunee County Fairgrounds, June 7, 2017. They presented data showing that both human and bovine wastes contributes to the contamination. “I cannot think of a hydrogeologically worse place than northeast Wisconsin to put a lot of cows,” said Muldoon.
