Dunn County offering free groundwater testing

Starting in July 2025, Dunn County is offering a limited number of free private well water testings for nitrates! Land & Water Conservation staff will come to your property to collect the sample, and the Dunn County Health Department will analyze the water for nitrates. There is no cost to participate! Take advantage of this opportunity to check your water quality!
