The City of Flint's Water Switch

After the switch, it was obvious to everyone that something was different about the water from the Flint River. Residents were told they could safely resume drinking the water just four days later. In August 2014, Flint's water tested positive for total coliform bacteria which is an indication of other disease-causing bacteria such as E. coli. On January 2, 2015, the TTHM levels in Flint's water far exceeded the acceptable amounts established in the Safe Drinking Water Act. When consumed by humans, TTHMs can be carcinogenic.
