The article says water is equally lead-contaminated across the state of Michigan, and that the lead had been reduced in 2014 right after they transferred water from one source to another.
Experts
are worried the media are getting too far ahead of themselves. The numbers are “being horribly exaggerated,” Hernan Gomez, an associate professor at the University of Michigan and medical toxicologist at Hurley Medical Center, told The Daily Caller News Foundation in September 2018.
Blood lead levels (BLLs) are no higher in Flint than in other cities across Michigan, said Gomez, who noted that there is no acceptable level of lead in drinking water even if there is a level that is considered tolerable.
The Centers for Disease Control and Prevention (CDC) considers a BLL in children of 5 micrograms per deciliter (µg/dL) and higher to be a “reference level.” The annual percentage of Flint children whose BLLs rose above the reference level increased from 2.2 percent to 3.7 percent, a relatively small uptick given actual lead levels, Gomez noted in a 2018 research paper.
These numbers are small relative to previous decades, with the average toddler in the 1970s holding a
BLL of 14 µg/dL, a number three times higher than the reference level. Those numbers fell to
0.84 µg/dL by 2014 following a government ban on lead in paint and gasoline in 1971. Children with blood lead levels of 5 µg/dL or higher dropped in Flint from 11.8 percent in 2006 to 3.2 percent in 2016.
CDC recommends treatment for people with BLLs at or above 45 µg/dL.
Hmm. Seems the OP has left the building.
