Private Water Testing

Clean drinking water is the basic essential to good health

Water testing is an inexpensive and effective way of assuring a safe and healthy water supply. It’s estimated that 20-25% of Wisconsin wells have bacterial contamination. Oneida County Health Department advises all private well owners to have their well water tested for coliform bacteria and nitrates annually, especially if infants under six months of age or women of childbearing age drinking the water, or sooner if changes in taste, odor or appearance are noticed, or there is an unexplained illness.

Oneida County Health Department’s state certified Water Analysis Lab provides convenient, reliable, and reasonably priced well water testing for both home and vacation properties. This service is available to anyone; you do not need to be a resident of Oneida County. Lab tests completed on-site include coliform and E-Coli bacteria, with definitive results within 48 hours. Through a partnership with UW-Oshkosh, Oneida County Health Department’s Water Analysis Lab offers additional testing options including nitrates, nitrites, and arsenic. Test kits from other public labs are available at the front desk, fees may apply.
