Which bacteria is commonly removed during water treatment?

E. coli is commonly removed during water treatment processes because it is a well-known indicator of fecal contamination and poses significant health risks to humans. Its presence in water signifies that pathogens that can cause serious gastrointestinal diseases may also be present. Water treatment facilities implement various methods, such as filtration and disinfection (including chlorination, ultraviolet light treatment, or ozonation), specifically targeting E. coli and other harmful bacteria to ensure that water is safe for consumption.

By focusing on the removal of E. coli, water treatment systems can effectively reduce the potential for outbreaks of diseases associated with contaminated water, thus protecting public health.
