Water Water Well Disinfection & Inspection
Disinfection and a well inspection are recommended when your well water tests positive for micro-organisms 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 can cause disease. If a well tests positive for coliform bacteria, testing for E. coli may be a prudent next step.
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.
Caution! Chlorine compounds are most commonly used to disinfect water wells. These compounds can be a breathing or explosion hazard. Also, it’s not recommended to use household bleach to chlorinate wells. Bleach is not designed for use in drinking water.
Recurring bacteria could indicate:
- A breach in the well system’s sanitary seals
- A nearby contamination source such as a failing septic system
- The need for a well cleaning.
- If bacteria is recurring in your water, consult with a qualified water well system contractor on how to proceed.
What do you know about your Water Well?
It is important that private well (water borehole) owners take a little time to learn about how to be a good steward of their water well systems, which includes testing the water and acting to improve water quality if necessary.
