Water Safety
Clean, safe drinking water is vital for good health. Testing your private well yearly helps protect you and your family. An estimated 20–25% of Wisconsin wells have bacterial contamination. CCHD recommends testing for coliform bacteria and nitrates, and for fluoride if infants or women of childbearing age use the water.

How do I test my private well drinking water? How often do I need to test?
Test your private well water with help from the Clark County Health Department. Pick up a sample bottle, instructions, and lab form. Results are ready in 24 hours. Most wells are safe, but contaminants like bacteria and chemicals can affect groundwater. Wells should be tested yearly and if water changes in taste, color, or smell. CCHD currently tests for bacteria only. Call (715) 743-5112 for more info.
