The WI DNR has reported that individuals who attend the 2021 Wisconsin Farm Technology Days this year can have their well water tested for free. The event runs July 20-22nd in Eau Claire. They’ll be screening for Nitrate, the most common contaminant found in Wisconsin’s groundwater. The DNR reports that nearly 1 in 10 private wells in Wisconsin may contain high levels of nitrate. Results of the screening will be available on the spot in a few minutes. DNR staff will be on hand to answer questions, and may recommend additional testing if elevated nitrate levels are detected.
