A Michigan health official told Congress that his department’s “initial analysis” showed blood lead levels in Flint children in the summer of 2014 were “within range of years before.” That’s false. That analysis concluded blood lead levels “were higher than usual” from July to September 2014, shortly after the city switched its water supply.
On April 25, 2014, the city of Flint began using the Flint River as its water source, as reported in the Detroit Free Press. But the Flint River has particularly corrosive water, which led to high levels of lead leaching into the water from many of the city’s dated pipes. Soon after the water supply switch, Flint residents began complaining about the color of the water, rashes and other issues.
Then, in July 2015 the Michigan Department of Environmental Quality told Michigan Gov. Rick Snyder that issues with water contamination in Flint were limited to one house and not widespread. At the same time, the Michigan Department of Health and Human Services claimed the elevated blood lead levels in children followed a normal seasonal trend.
The link between Flint’s water switch and elevated blood lead levels in children wasn’t confirmed until two independent researchers, Marc Edwards and Mona Hanna-Attisha, each put forth their own analyses in September 2015.
