Is your water well system clean?

NGWA Certification

A common mistake made by homeowners is to test their well water without first making sure the water well system is clean. Testing water from a dirty well can lead to false positives-the appearance of contamination even when the ground water is clean. A dirty well also can create an environment or contaminants such as certain types of bacteria.

A qualified water well system contractor can determine if your water well system needs cleaning by conducting an anaerobic bacteria test, a coliform test, or other tests that can indicate an accumulation of debris in the well.

Anaerobic bacteria can be an indicator of overall bacterial activity in the well-including possibly harmful bacteria. A qualified professional water well system contractor can take a water sample to determine if the amount of anaerobic activity in your well is significant.

While most coliform bacteria are not harmful, they serve as indicators of possible harmful bacteria.

Other possible indicators of a dirty well may be cloudy water, low water flow, or taste and odor problems.
