Beware of flooded wells

With the recent heavy rains in some areas there is increased danger of private wells becoming contaminated. The Wisconsin Department of Natural Resources encourages well owners, especially in flooded areas to monitor their water closely. Any change in the color, smell or taste of water could indicate a problem.

Flood waters and runoff contain bacteria and other contaminants that can cause water-borne illness. Wells located in pits, basements and low-lying areas are especially susceptible to contamination. If you think your system is contaminated, stop using the water immediately and have the well tested.

Any water supply system submerged by flood waters should be pumped out once the floodwater recedes, then thoroughly disinfected and tested to determine that the water is safe. Disinfection and sampling is best done by a licensed well driller or pump installer.

Well owners are also encouraged to test their wells annually for bacteria and nitrates.
