A Holstein steer from Kewaunee County at the Wisconsin State Fair. Cattle have a role in polluted wells in the county, as do humans, a new study says

"Lee Luft, a member of the Kewaunee County Board and chairman of a county task force on groundwater, said the results will be construed as deflecting some of the criticism away from agriculture. He said, however, the study points to the region’s problems. “What we have on our hands here is a combination of problems: The ineffectiveness of some septic systems, but when there is significant groundwater recharge, what we see is a problem from bovine sources,” he said.
