How do you treat coliform bacteria?

Can you filter out coliform bacteria?
Biological contaminants such as coliform bacteria are most effectively eliminated through chlorine disinfection, filtration , ultraviolet irradiation, and ozonation.
What to do if you have coliform in your water?
When coliforms have been detected, repairs or modifications of the water system may be required. Boiling the water is advised until disinfection and retesting can confirm that contamination has been eliminated. A defective well is often the cause when coliform bacteria are found in well water.
Does boiling water get rid of coliform?
