We've been using this water for years and we're OK

Bacterial contamination of private water supplies is common, so why aren't more people sick?

1. The coliform bacteria identified in a water test do not cause disease. These bacteria are used to identify an unsanitary water supply and indicate the risk of exposure to a water-borne disease.

2. Water-bome diseases may be mistaken for the flu or food poisoning.

Remember that coliform bacteria in your water supply are a warning of contamination. Only through routine water testing, proper water supply construction and protection, and any necessary water treatment can you ensure a safe water supply for your family and livestock.
