"CLICK HERE" (below) takes you to the Montana State University Extension website.
On the MSU site, under the alphabetical list of "Fact Sheets," scroll down to "Coliform and E. coli bacteria." This will open a new window with a Well Educated fact sheet entitled "Total Coliform and E. coli Bacteria."
This fact sheet covers general information on the bacteria themselves, what actions need to be taken if your well tests positive for total coliform bacteria or E. coli bacteria, places to look for the source of the contamination, and how to treat a private well for bacterial contamination.
