FLINT, Mich. (AP) - A city official says he intended to treat Flint's drinking water with anti-corrosive chemicals after the city switched from the Detroit system to the Flint River nearly two years ago but was overruled by a state environmental regulator.
During a hearing before a legislative committee Tuesday, city utilities director Mike Glasgow said he met with a Michigan Department of Environmental Quality district engineer shortly before the switchover in April 2014.
He said the engineer told him a year of testing was required to determine whether corrosion control was needed.
The failure to use corrosion controls enabled lead to leach from pipes and fixtures and contaminate the water supply. Elevated lead levels have been detected in some homes, businesses and schools - and in the blood of some children.
