Disinfecting Water Wells photo

Water well construction requirements protect our subsurface drinking water supplies utilizing sound drilling practices that prevent aquifer contamination from the surface. However, natural disaster events, such as extreme flooding, may compromise even the best constructed water wells. Owners of private water wells should take precautions if the threat of flooding exists, and specific steps should be taken if water wells are impacted by flood waters. It is important to disinfect a water well if the well has been impacted by flood water, a water sample tests positive for bacteria, or when work on the well, such as a pump replacement or liner installation has been completed.
