ST CROIX COUNTY, WI – St. Croix County is holding our next nitrate screening clinic at the Deer Park Library — 112 Front Street West, Deer Park, WI — on Tuesday, August 12 from 1 to 5 pm. These events give our communities an opportunity test the safety of their drinking water.
If you have a private well, you should test your water annually even if you do not observe any smells, staining, or changes in the taste of your drinking water. The clinic offers nitrate-nitrogen screening because elevated levels can pose health risks, especially for pregnant women, infants under six months old, and people with certain health conditions.
The nitrate screening results are provided on-site, and staff will be available to discuss and interpret the results. The clinic is open to St. Croix County residents who are interested in testing their private well or public supply drinking water for nitrates. Participants are asked to bring in about eight ounces of water in a closed container, preferably glass, collected within 24 hours of the clinic event. It is important to run the tap for ten to fifteen minutes on cold at full flow before collecting the sample.
Participants who have more than one private well may bring in a sample from each well and may also bring in samples from family and friends. Residents with water treatment systems, such as reverse osmosis, are encouraged to bring in a sample pre and post treatment to test the treatment system to ensure it is functioning properly.
