Our laboratory is certified by the state to test drinking water. We offer water testing for 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.  

Testing Process

  1. Decide which tests

    Different test options require different kits. We can help you figure out what tests or packages to order. Email lab@publichealthmdc.com or call us at (608) 243-0357. We will discuss the types of tests you need based on your situation and their cost. 

     If you already know what tests you want to order, go to step 2.

  2. Get a Test Kit

    • All testing requires the use of a Public Health Madison & Dane County water testing kit.
    • Depending on what type of testing you want, you might need more than one kit.
    • Water test kits must be ordered in advance! Email or call us at (608) 243-0357 to order. You can pick them up at our office, or we can mail them to you for a $5 fee.

Free Drinking Water Testing For Those who Qualify

If a pregnant person or baby under 6 months lives in your home and you have financial need, water testing of your private well is available for free. This uses a different testing kit and lab than the process above. For PFAS testing, see information above under "Private Well Testing for PFAS."

Please call (608) 242-6515 to find out if you qualify for free testing. You can also visit our office at 2300 S. Park St. Suite 2010.

If you do not qualify for free water testing, you must follow the process above and pay the fees.
