Drinking Water/Well Water

Owners of private wells are responsible for maintaining and protecting their wells. While most private wells in Wisconsin provide safe drinking water, some may contain substances that can affect your health. Many of these substances do not affect the color, smell, or taste of the water. The only way to verify that well water is safe for drinking is to test regularly. Here are the testing recommendations:
