Flooding could affect our local drinking water wells

The Lincoln County Health Department advises that recent flooding may have impacted some private drinking water wells serving residents in Lincoln County. “Many of the wells serving Lincoln County residents are old, located in low areas and prone to contamination during periods of spring run-off and other flooding events,” said Public Health Administrator Ed Dzedzy. “Even if the rising waters didn’t reach a well, it could have impacted the water quality, and that could pose a health risk to those drinking that water.”

If the area around a private well has been flooded or there is any suspicion or risk that the well has been contaminated from flood waters, consumers are advised to stop using it for drinking water, cooking, brushing teeth and bathing and have it tested before continued use.

Warning signs that a well may be unsafe include debris, muddy or cloudy water, erosion or instability in the ground surface around the well, damage to the well casing and unusual odor, taste or appearance. If any of these signs appear, or if impact to a well is suspected, the Health Department recommends using bottled water until the well can be tested at a certified laboratory and disinfected if necessary. The Health Department can test water samples for coliform bacteria ($25.00). Other certified laboratories are available in Spokane and Grant Counties. Contact the lab to receive a sample bottle and instructions before collecting the sample. It is recommended that the well be tested for bacteria annually and for nitrates every three years.

If the well shows signs of flooding or has tested positive for bacteria, it is important to disinfect the well before consuming the water. The Lincoln County Health Department can be contacted at 509-725-2501 for information regarding well disinfection or well contractor can be called upon for assistance.
