Floods Can Affect Your Well Water's Well-Being
North American Precis Syndicate
(NAPSI)—For over a million families, farmers and business owners,
seeing floodwaters receding may just be the beginning of their troubles—but
it doesn’t have to be.
The National Ground Water Association (NGWA)—a not-for-profit
professional society and trade association—says people who have inground wells in areas affected by flooding need to
watch for contaminated water.
This is particularly likely to be a problem in Illinois, Indiana, Iowa, Kansas, Kentucky, Minnesota, Missouri, Nebraska,
South Dakota, Wisconsin and any place with broad, sand and gravel valleys and
glaciated rolling countryside. These places could be standing in water for
several days, risking contamination if the wells aren’t properly
maintained. Exposure to E. coli, coliform and other
pathogenic microbes from human and animal fecal matter in floodwaters is a
common health concern following a major flooding event. Floodwater can also
carry other contaminants.
“Even slight flooding around a well can potentially carry
contaminated water to the wellhead,” explained Chuck Job, NGWA
regulatory affairs manager, “and if the wellhead is cracked or faulty
in any way, the well and water system could be compromised.”
Adds Bill Alley, NGWA science director, as temperatures rise, well owners
should continue to monitor and test their systems. “While frozen ground
may not be saturated from storm water, warmer weather may allow floodwaters
to infiltrate and contaminate subsurface water during a thaw,” he said.
Similarly, hundreds of thousands of wells were potentially affected during
the Atlantic hurricane season in places including North Carolina, Georgia,
South Carolina, Florida, Virginia and Alabama.
What To Do
Following a flood, disinfection and wellhead repair may be common needs
among well owners. Well relocation and elevation may also be useful and
protective. As always, NGWA recommends water well system professionals be
used to assess and service wells.
NGWA has a flooding resource center on its website. Included is
information on how to protect well systems before and after a flooding event.
The association also has other resources that may help when dealing with
flooded water wells. These include the best-suggested-practice “Residential
Water Well Disinfection Following a Flood Event: Procedures for Water Well
System Professionals” and a Water Well Journal article titled “Responding
to Flooded Wells.”
