Well Water Disinfection

Disinfection and a well inspection are recommended when one’s well water tests positive for microorganisms such as bacteria, viruses, and protozoa (single-cell animals).

Wells are routinely tested for coliform bacteria—organisms in soil or vegetation, and in the intestinal tract of warm-blooded animals. Most coliforms are harmless. Their presence indicates whether the well environment can support disease-causing bacteria.

Some strains of E. coli are disease causing—even lethal. If a well tests positive for coliform bacteria, testing for E. coli may be prudent.

A water well should be disinfected:

- When the water tests positive for coliform bacteria
- After well construction
- After well servicing
- If there is a well-system defect that could allow bacteria into the well.

The National Ground Water Association recommends qualified water well professionals conduct system disinfections. Proper well disinfection involves chemistry and proper application techniques, so the potential is great for well owners to improperly disinfect their well systems.
