How to Remove E. coli from Water [year]

E. coli might sound like an unlikely pathogen to contaminate water in the United States.

In this story, we’ve shared everything you should know about the 7 most effective treatment methods to remove or kill E. coli bacteria in water.

Here are the best water treatment methods to kill or remove E. coli bacteria from your drinking water.
