E. coli in Vermont well water

In Vermont, 0% of 8 tested private well samples exceeded the EPA limit for E. coli (0 MPN/100mL).

E. coli in a well means fecal contamination from septic systems, animals or surface water entering the well. It can cause serious gastrointestinal illness. Any detection is a failure.
