Flint was once one of the richest cities in the United States. But in the 1980s, it was badly affected by the downturn in car manufacturing and by 2014 it was nearly bankrupt. To save money, the city switched its water supply away from Lake Huron to its own Flint River, but state officials failed to treat the river water properly. As a result lead, a powerful neurotoxin, was released into the drinking water. Despite mounting evidence, officials denied anything was wrong and it took them a year and a half to switch water supply back to Lake Huron. But many residents of Flint –a majority African-American city with high rates of poverty– have been left fearful about the long term impacts on their children. Rob Walker speaks to lifelong Flint resident Jeneyah McDonald who had two young children at the time. He also hears from Dr Mona Hanna-Attisha – a paediatrician and professor of public health– who helped bring the scandal to national attention after showing that lead had found its way into the bloodstreams of the city’s children.
