What happens if Total Coliforms are found in my water?

When coliform bacteria are found, water systems investigate to find out how this got into the water. They collect additional, or “repeat,” water samples for testing, and often inspect the entire system. Taking repeat samples helps determine whether an actual problem exists in the system. If any of the repeat samples detect coliform bacteria, the initial findings are considered confirmed. In the event of the City incident, all recollect samples were negative, an indication that the one positive result was irregular. As shown in the table above, the City has not had a positive result from 2013 to 2020 and since the May 2020 sampling event.
