Private Well Testing
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 annually for coliform bacteria. If there are infants under six months of age or women of childbearing age drinking the water, the water should be tested for nitrates as well.
