“Reference levels” aren’t poisoning, Flint at the height of the episode had lower blood-lead incidence in children than many other communities large and small, the number of cases with lead exposure calling for therapeutic measures appears to have been zero, and so forth. “It is not possible, statistically speaking, to distinguish the increase that occurred at the height of the contamination crisis from other random variations over the previous decade.” In short, everything you know about the Flint water episode is wrong.
