New national drinking water rules are expected to lead to fewer dangerous pathogens coming out of the tap.
The new regulation, which was announced last month and takes effect within three years, switches focus to a type of bacteria that more accurately reflects the presence of pathogens that can make people sick.
The Environmental Protection Agency estimates that its revised rules will cost U.S. utilities an additional $14 million a year. About 155,000 public water systems, providing water to more than 300 million people, must comply.
