New University of Michigan research appears to confirm that improper corrosion controls caused Flint's water crisis.

The team of UM researchers focused on the layer of lead scale inside ten service line samples from around Flint. Service lines connect homes and businesses to city water mains. In addition to examining pipe samples under a scanning electron microscope, the researchers pulverized the pipe linings to analyze what they're made of.
