Why is a boil water advisory issued?
From the State:
What should I do?
As a precaution until additional testing can confirm the absence of coliform bacteria, you are advised to boil all water used for human consumption or use bottled water. Bring all water to a boil, let it boil for one minute, and let it cool before using, or use bottled water. Boiled or bottled water should be used for drinking, making ice, brushing teeth, washing dishes, and food preparation until further notice. Boiling kills bacteria and other organisms in the water.
If you have a severely compromised immune system, have an infant, are pregnant, or are elderly, you may be at increased risk and should seek advice from your health care providers about drinking this water. 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 as 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. However, we advise customers to boil water used for human consumption until we have determined that the coliform bacteria are no longer present in the system. After we have determined that coliform bacteria are no longer present we will rescind the boil water advisory.
