(WESTERVILLE, OH — April 25, 2013) After a flood, the owners of household water wells should take precautions to make sure the water is safe to drink and the wells are in good operating condition, according to the National Ground Water Association.
During a flooding event, contaminated water may have topped and infiltrated the well, carrying with it bacteria, chemicals, or other pollutants, said Cliff Treyens, NGWA public awareness director. One should use bottled water until a qualified water well system contractor can check out the well system and disinfect it. Boiling water is intended to kill bacteria, but not to treat chemical contamination.
A less obvious, but just as important, concern is electrical shock if a nonsubmersible pump or any part of the well electrical system is flooded. As water wells are specialized systems that require knowledge and expertise to repair, hiring a qualified water well system contractor to check out the well system makes the best sense, Treyens said.
To summarize, after a flood, one should:
One should also check with local health or environmental health authorities about other substances to test in well water following a flood, as there may be pollutants of local concern, Treyens added. Also, use a qualified drinking water testing lab. Follow its advice on how the sample should be taken and to analyze the results.
