Types of Well Water Bacteria a UV will remove:

Bacteria  A many number of all wells have unacceptable levels of total coliforms.  This suggests that disease causing organisms could be present.  A major cause of this contamination is insufficient well maintenance.

Coliform organisms are a group of bacteria that are frequently found in the environment and are used to measure the safety of your water. 

If coliform bacteria are present in your water, it tells you that other disease causing organisms may be in your water supply. 

The presence coliform bacteria in a water sample may mean that surface water has washed contaminants into the well.

E Coli bacteria live in the intestines of humans and warm blooded animals.

There are many different types of these bacteria that can make you very sick.

If any amount of E Coli bacteria is found in a water sample, human sewage or animal feces has contaminated the water supply.

When a water sample shows a certain level of the presence of ecoli and coliform bacteria, it is considered unsafe to drink until the problem is corrected. The bacteria could possibly pose a health risk.  The water should not be used for drinking until the problem has been found and corrected.  An alternate drinking water supply should be used.
