E. coli in Kansas well water

In Kansas, 2% of 2,128 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.

Type the value from your lab report. It is compared to the EPA limit, the same way the full interpretation does it.
