Thousands of Flint’s residents (mainly poorand black) have been exposed to lead and other pollutants in their drinking water. In April 2014, the Government of Michigan -Richard Snyder as governor from the Republican party-switched the main city's water source from the Detroit Water and Sewarage Department (sourced from lake Huron and Detroit river) to Flint River. The main reason was that Flint city terminates its water service contract with the city of Detroit, and in order to reduce costs the city had a project to build a new pipeline to deliver water from Lake Huron to Flint. But as the construction of the pipeline was delayed, the water source switched to the Flint River. This is a very contaminated river that in the past was a repository for industrial waste. Since 2014, the corrosive water from the Flint River leached the lead from the old water pipes, mixing in the water supply and producing extremely high levels of lead. According with a scientific analysis in 2015, Flint River water has 10 times more lead compared to the same system using Detroit water (Edwards et al 2015).
