Private Water Supply Wells Program
Safe, clean water is one of the most vital resources we have for drinking, cooking, bathing and cleaning. Municipalities regularly test the drinking water supplies to ensure they are safe. But it is the homeowner’s responsibility to test their well. Waukesha County has over 40,000 private wells, but most are not tested for coliform bacteria and other contaminants on the recommended annual basis. Many of these contaminants can cause sickness in people who drink, bathe, or cook with the water.
