A group of doctors led by Dr. Mona Hanna-Attisha of Hurley Medical Center in Flint urges the city to stop using the Flint River for water after finding high levels of lead in the blood of children. State regulators insist the water is safe.

“D.E.Q. and D.C.H. feel that some in Flint are taking the very sensitive issue of children’s exposure to lead and trying to turn it into a political football claiming the departments are underestimating the impacts on the populations and particularly trying to shift responsibility to the state.”
