It is crucial to ensure the safety of well water by regularly monitoring and treating it to prevent the proliferation of these potential health hazards. Viruses and cysts are very expensive and hard to test, so coliform test is usually performed in their place. If there is no coliform, there won’t be any viruses or cysts.
