Clean Water For All

Near Maiden Rock, along the banks of the Rush River, Larry Brenner built Vino in the Valley into one of western Wisconsin’s most beloved dining destinations. Locals and tourists alike can enjoy delicious meals and wine while feasting their eyes on breathtaking views of the Rush River Valley. But the clean water that Larry’s business depends upon is at risk.

Concentrated Animal Feeding Operations (CAFOs) have expanded throughout Pierce County, and these facilities are linked with nitrate contamination. Larry’s already seen what happens when water becomes unsafe. His other restaurant has failed nitrate tests, forcing warnings to customers that the water is unsafe for consumption. In Larry’s words, this is simply a “death knell” for a restaurant.

Property values, our wells, the environment, these are all things to be very concerned about.

In spite of the dangers inherent in nitrate-laden drinking water, when contamination occurs, the DNR isn’t obligated to notify local health departments, meaning families and small businesses often have no way of knowing their wells are unsafe. Larry’s story is a reminder that clean water is vital to Wisconsin’s communities, businesses, and way of life. Everybody deserves the right to know what’s in their water.
