Bacteria in tap water can be traced to the water treatment process

Most of the bacteria that remain in drinking water when it gets to the tap can be traced to filters used in the water treatment process, rather than to the aquifers or rivers where it originated, University of Michigan researchers discovered.

Eventually, the work could enable engineers to control the types of microbes in drinking water to improve human health like "live and active cultures" in yogurt, the researchers say.
