For all the concern about Flint and lead in the water, I was shocked to learned that despite lead levels in the water increasing, lead blood levels in children were still much lower than a decade earlier. They did increase, but they were still less than half the level in 2006.

The study, which appears in the Journal of Pediatrics, found a decrease in Flint childhood blood lead levels, from 2.33 micrograms per deciliter in 2006 to 1.15 micrograms per deciliter in 2016 — a historic low for the city. The mean blood lead level in 2015 during the height of the water crisis was 1.3 micrograms per deciliter, up from 1.19 in 2014 before the water source switch.
