(CNN)The levels of lead in Flint, Michigan’s water checked listed below the federal limitation in a current six-month research study, the state department that manages water quality revealed Tuesday.
The research study, for the duration starting July 1 and ending December 31, discovered levels of lead were 12 parts per billion or lower in 90% of the samples taken, considerably lower than the action level of 15 ppb, the Michigan Department of Environmental Quality stated.
In December, Michigan Attorney General Bill Schuette revealed felony charges versus 4 authorities for their function in the water crisis, bringing the variety of previous and existing civil servant called to account to 13.
Among the 4 charged late in 2015 were 2 previous Flint emergency situation supervisors who were designated by Snyder. They are the highest-level authorities to be charged up until now.
