Coliform bacteria gets into wells when:
- 1Work is done on the water supply such as pipe replacement or repair of a pipe, well seal, pressure tank or a backflow
- 2Well seal is bad from lack of maintenance
- 3Surface water has gone down the OUTSIDE of the casing to the deeper water
- 4A backflow from an irrigation system, plumbed-in spa or pool, or other non-potable water use backflows into the well
OR there was a sampling error and the well is fine. However it may take several water samples to determine that.
In a sealed cased well that is maintained, surface water should be being held out. Surface water is where coliform bacteria live.
