One of the recurring problems in the aftermath of the weekend’s flooding is the problems of disinfecting flooded wells.

According to Bob Nelson, Austin-Mower County emergency preparedness director, if a well casing has been submerged in flood water, the well should be considered contaminated by bacteria or viruses, which can make people ill.

"Any water used for drinking or cooking must be boiled at a rolling boil for at least five minutes," Nelson advised.

The boiling must be done until the well and entire plumbing system have been disinfected and tested, according to Nelson.

In the mean time, bottled water could be used for human consumption and cooking.

There are specific steps that must be taken when a flooded well is disinfected to ensure the process works satisfactorily.

Also, if a well had an inadequate well seal or cover, debris or sediment may have entered the well.

Nelson advises the well should be cleaned out by a licensed well contractor and the water should not be used for drinking or cooking until the well has been properly cleaned, disinfected and tested safe.
