Blood Lead Levels Among Children Aged <6 Years — Flint, Michigan, 2013–2016

Researchers in the Morbidity and Mortality Weekly Report share the results of blood lead level testing in children less than six years old in Flint, Michigan. 

They analyzed blood lead level surveillance data from April 25th, 2013 to March 26, 2016.  These dates correspond to before the switch to the Flint Water Authority to the return to the Detroit Water Authority after the use of Flint water.  This period was split into four smaller time periods corresponding to the different events: before the switch from the Detroit Water Authority to the Flint Water Authority, after the switch from the Detroit Water Authority to the Flint Water Authority, but before the water advisory was issued, after the switch to the Flint Water Authority and after issuance of the water advisory, and after the switch back to the Detroit Water Authority from the Flint Water Authority.  The research showed blood lead levels increased after the switch to the Flint Water Authority in children under six.
