Total coliform in Texas well water
In Texas, 0% of 13 tested private well samples exceeded the EPA limit for total coliform (0 MPN/100mL).
Coliform bacteria live in soil and on plants as well as in sewage. Their presence means surface water or soil is getting into the well through the cap, casing or a nearby defect. Most coliforms are harmless, but they mean disease-causing organisms can get in the same way.
