DNR Warns that Snowmelt, Rain Can Contaminate Wells

Wisconsin Ag Connection - Warming temperatures, snow melt, rain and lingering frozen ground can create conditions that may affect private wells and drinking water. Liesa Lehmann, DNR private water section chief, says the added precipitation and local flooding throughout the state is a reminder that changing spring weather can lead to well contamination.

"At this time of year we encourage well owners to watch for signs of flooding and note any change in the color, smell or taste of their drinking water," Lehmann said.

Owners who see flood waters very near or over their wells should assume their drinking water could be contaminated. As a result, they are encouraged to stop drinking the water and find another safe source. Once the waters recede, make sure the well is properly disinfected.

Flood waters and rain runoff may contain bacteria and other contaminants that can affect water supplies and cause illness. Wells located in pits, basements and low-lying areas are especially susceptible to contamination.
