University of Nebraska-Lincoln extension experts are warning that recent floods from storm runoff could put private drinking water wells at risk of contamination.
UNL Extension water quality educator Sharon Skipton says that if floodwater came near a private drinking water well, its water supply may have been contaminated with pollutants carried in the floodwater.
Wells at greatest risk include those in well pits, dug wells or any wells without a watertight casing or cap. Also, wells that lack a grout seal in the annular space or were submerged with flood water or surface water runoff are at risk.
Homeowners who think their private drinking water well was affected by floodwater should not use the water for cooking, drinking or brushing teeth until lab tests confirms it is safe.
