The Flint water crisis was caused by failing to perform corrosion control: In April 2014, because of annual rate increases from the DWSD, the Flint City Council voted to join the Karegnondi Water Authority (KWA), which would be developing a raw water supply pipeline from Lake Huron. The water supply contract with DWSD was subsequently terminated, and the Flint water treatment plant began treating water from the Flint River on a full-time basis and distributing the treated water to residents and other customers. When the plant went into full-time operation, the Michigan Department of Environmental Quality (MDEQ) did not implement corrosion control, as mandated by the LCR. Instead, the Flint water treatment plant was allowed to complete two six-month monitoring periods without corrosion control and then the MDEQ would decide if corrosion control treatment was necessary. https://www.materialsperformance.com/articles/material-selection-design/2016/06/the-science-behind-it-corrosion-caused-lead-tainted-water-in-flint-michigan https://www.materialsperformance.com/articles/material-selec...
