Tests Show Coliform Bacteria
Our water system recently violated a drinking water standard. Although this is not an emergency, as our customers, you have a right to know what happened, what you should do, and what we did to correct this situation.
We routinely monitor for the presence of drinking water contaminants. We took eight (8) samples for coliform bacteria during July. Two (2) of those samples showed the presence of coliform bacteria. The standard is that no more than one (1) sample per month may do so.
What should I do?
People with severely compromised immune systems, infants, and some elderly may be at increased risk. These people should seek advice about drinking water from their health care providers. General guidelines on ways to lessen the risk of infection by microbes are available from EPA’s Safe Drinking Water Hotline at 1(800) 426-4791.
What does this mean?
This is not an emergency. If it had been you would have been notified immediately. Total coliform bacteria are generally not harmful themselves. Coliforms are bacteria which are naturally present in the environment and are used as an indicator that other, potentially-harmful, bacteria may be present. Coliforms were found in more samples than allowed and this was a warning of potential problems.
Usually, coliforms are a sign that there could be a problem with the treatment or distribution system (pipes). Whenever we detect coliform bacteria in any sample, we do follow-up testing to see if other bacteria of greater concern, such as fecal coliform or E. coli, are present. We did not find any of these bacteria in our subsequent testing. If we had, we would have notified you immediately.
What happened? What is being done?
Again, there is nothing you need to do at this time. We completed follow-up testing to see if other bacteria of greater concern, such as fecal coliform or E.coli were present. Again, our sampling shows that no bacteria are present and no corrective actions are necessary.
