Our Laboratory is certified by the State to test drinking water for bacteria, metals, nutrients, and other chemicals. We offer water testing for individuals (homeowners/renters) and public water utilities.
When to Test Your Water
Recommendations for testing vary depending on;
- the source of your water (private well or municipal water),
- age of your home, and
- who lives in your household.
Private Well Owners
It is recommended that private well owners test annually for bacteria and nitrate/nitrite. Testing is recommended sooner if there has been flooding in the area or if any changes in taste, odor, or appearance of the water are noticed.
- It is very important to test for nitrate in households with pregnant people, infants, and young children. Nitrate can reduce the blood's ability to carry oxygen. In infants it can cause a serious condition called "blue baby syndrome."
- The age and type of plumbing may indicate a need for additional testing to check for lead and other metals. While lead is less of an issue in private wells, it can be found in some pumps or valves used in private wells.

Municipal Water Customers
If you pay a water bill, you have water that comes from a municipal water utility. The water utility tests the water regularly and makes sure that you have good drinking water.
- You may want to test for water quality problems that may come from your plumbing, like lead, copper, manganese or bacterial contamination.
- Test drinking water for lead if you know there is lead piping or solder where you live, or in the system that brings water to where you live. Galvanized steel pipes can also add lead to the water. We can help figure out if you have lead pipes. Call our office at (608) 242-6515. This website can also help you find out. Lead levels may vary widely throughout the home so one good test may not be the final answer.
- If your water is cloudy or discolored, it may be due to flushing of water mains which is part of normal cleaning and maintenance. The cloudiness and discoloration should clear up after running the water for a few minutes. It does not usually mean testing is needed. If the water does not become clear, call your local water utility.
Other Water Testing
We test more than just drinking water. We can test area lakes, streams, and rivers for indicators of environmental conditions.
