Test your well water every year for contaminants including coliform, bacteria, and nitrates. You should also test if you notice any change in taste, odor or appearance, or after flooding.
Visit our Drinking Water Testing page for testing information or call our lab at (608) 243-0357. We can recommend other tests depending on your well's location, age, etc.
Abandoned or unused wells can contaminate the aquifer. This can affect the safety and quality of ground water and drinking water. Financial assistance for well abandonment may be available from the WI Well Compensation grant program.
