Coliform bacteria detected in Lewistown water supply
The advisory was issued in late October after recent tests which indicated the presence of coliform bacteria in the water supply, a violation of drinking water standards.
The City of Lewistown said in a notice posted on its website: "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."
City officials said that seven samples were tested for the presence of coliform bacteria during October 2017.
Two of the samples showed the presence of total coliform bacteria.
The city provided the following information about the situation: What should I do?
These people should seek advice about drinking water from their health care providers.
Total coliform bacteria are generally not harmful themselves.
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 are increasing sampling for coliform bacteria and investigating for the source of contamination.
We will inform you when our sampling shows that no bacteria are present.
