Drinking Water Testing
As COVID-19 continues to impact us locally, we will be closing all Public Health Madison & Dane County offices to the public effective Thursday, March 19, 2020.
Although this decision was not arrived at easily, it is a decision that we needed to make. We are prioritizing preserving the health and safety of our staff and clients while continuing to maintain our ability to provide essential services, including our response to COVID-19.
We will continue providing services through alternate avenues, detailed below, but at this time we are reducing our direct contact with the public.
The Lab will be reducing testing services. Specifically:
Private Water and Lead Paint Testing resumes August 10th with new measures put in place. Please call (608) 243-0357 or e-mail firstname.lastname@example.org for general water testing questions.
- Water testing kits available by curbside pickup at the City-County Building or USPS delivery (add $5 shipping and handling fee).
- Water samples must be returned via curbside drop off at the City-County Building.
- To arrange pickup of water testing kits or drop off water and paint samples, please call (608) 381-8953.
Other laboratory services will continue as detailed below.
- Project water samples (Zoo, Pools, Water Utility) will continue to be analyzed.
- We will have lab staff available if emergency water testing is needed.
- The lab will continue respond to illicit discharge via the online complaint system.
Our Laboratory is certified by the State to test recreational and 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.
- Nitrate is very important to test for in households with pregnant women, infants, and young children. Nitrate can reduce the blood's ability to carry oxygen, and in infants 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, lead 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 assures that you have good drinking water.
- Municipal water customers may want to test for water quality problems that may come from the home plumbing such as 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. For guidance on how to find out whether you have lead pipes or not, call our office at (608) 242-6515 or check out this guidance from National Public Radio (NPR). Lead levels may vary widely so one good test may not be the final answer.
- When water is temporarily 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 a few minutes of running the water and does not usually mean a need for testing. If the water does not become clear, call your local water utility.
Other Water Testing
Our water testing services go beyond testing drinking water. We can test area lakes, streams, and rivers for indicators of environmental conditions.
