Flooding effects on Water quality of wells – Private or Public

We are all getting used to frequent and heavier rainfall than in the past. So how does this affect anyone with semi to rural property and private wells. The old thinking was that soil depth would filter out any contaminants by particle size and soil processes. Several studies done over 10 years ago, on wells under older central areas of the City of Madison, found E. coli contamination in the water. Most likely from broken old leaking sewer pipes in the old part the city. These particular wells were 450 to 500 feet deep below the street level. This single finding has changed the assumption about soil depth being enough to protect well water from run off contamination. The city over a long period of time dug up all the streets and yards replacing the pipes and sewers lines that were leaking many chemicals in addition to E. coli. Low cost loans programs were initiated so home owners could up date the aging internal plumbing that was also leaking inside the aging building and leaking into the water they were drinking.
