About 13.2 million households in the United States obtain their water from private wells, a method that offers no assurances of the water’s quality. Testing private wells can be expensive and results can take weeks. But two different types of water sensors developed by researchers at the University of Wisconsin-Milwaukee offer low-cost, immediate protection against the threat of contaminated water supplies.

The two technologies were developed collaboratively with industry partners in a Milwaukee research consortium called the Water Equipment and Policy Center (WEP). The companies, including three based in Wisconsin, have subsequently licensed the through the UWM Research Foundation. “These new technologies resulting from our WEP partnerships are helping Milwaukee compete in the $500 billion global freshwater technology market,” says Brett Peters, dean of the UWM College of Engineering & Applied Science. “Both sensors offer specificity that isn’t currently commercially available.”
