Tests Showed Coliform Bacteria in Dillingham Water System November 2006

Our water system recently violated the drinking water standard for total coliform (TC) bacteria. Although this is not an emergency, as our customers, you have a right to know what happened, what you should do, and what we are doing to correct this situation.

The Department of Transportation routinely monitors for the presence of drinking water contaminan. Two samples collected in November tested positive for the presence of total coliform bacteria. The standard is that no more than one sample per month may do so.

What should I do?

€ You do not need to boil your water or take other corrective actions. However, if you have specific health concerns, consult your doctor.
€ 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. 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 system’s 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 E. Coli, are present. We did not find any of these bacteria in our subsequent testing, and further testing shows that this problem has been resolved.

What happened?

On November 20, 2006, routine monthly samples were taken. One day later, test results indicated the presence of TC bacteria. A subsequent repeat sample taken on November 21, 2006 was also TC bacteria positive. The chlorine levels were increased to the system and samples taken on November 27, 2006 were negative for TC bacteria. We were unable to determine the source of the coliform. Samples indicate the contamination to be localized. We will continue strict monitoring to insure the integrity of the water system.
