Coliform bacteria in a well is a sign that contamination can reach the water, even though the bacteria themselves are usually not the danger. A positive test calls for action, not panic.
The test
Total coliform is a broad indicator, and a positive result means the well should be checked and possibly disinfected.
The source
Surface water, a failed seal, or a nearby septic system can let bacteria into the well.
The disinfection
Shock chlorination kills the bacteria in the well and the plumbing, followed by a retest to confirm it worked.
The permanent fix
If the problem returns, the well casing, cap, or the area around it needs repair. freezing winters and hard water are both common, and older homes often have aging supply lines In Northglenn, well owners should test annually.
The retest
After shock chlorination, a retest confirms the water is clean. If coliform returns, the well itself needs a repair, not just another dose.
