"Thirteen Michigan water systems failed to meet federal standards for lead in drinking water in the last half of 2018, and seven of those systems had lead levels at least twice as high as the state will allow starting in 2025.
Data requested by MLive-The Flint Journal from the Michigan Department of Environmental Quality shows water systems above that action limit in the most recent Lead and Copper Rule testing are located throughout the state and are both large and small -- one serving less than 100 homes and others providing water to cities as large as Hamtramck and Benton Harbor.
A total of 27 water providers registered 90th percentile lead levels of at least 13 parts per billion, beyond the 12 ppb future threshold established last year by the state."
