What could the water be contaminated with?
Bacteria - When a water test shows the presence of bacteria, it is considered unsafe to drink until the problem is fixed and the well is disinfected. The absence of bacteria in any one test does not ensure safety at other times. Regular testing throughout the year will establish your well water’s consistency and increase your confidence in its safety. Spring run-off, heavy rain events, or prolonged dry spells as well as wear and tear of the well structures or changes to the water catchment can all potentially affect the quality of your well water.
Total Coliforms - Total coliform organisms are a group of bacteria that are commonly found in the environment, and are an indicator of the safety of your water. Total coliform bacteria, if present, indicate that disease-causing organisms (bacteria, viruses, parasites) could potentially be present in your water supply.
