From Flint

Flint is a city of 100,000 people, with 41% living below the poverty line and an African-American majority. The city switched in 2014 to water from the polluted Flint River to save money, but the new water supply wasn't properly treated. Lead from aging lines leached into the local water supply, along with coliform bacteria and other contaminants, creating a serious health crisis. Up to 12,000 children may have been exposed to high levels of lead in their drinking water. Some residents were also forced to abandon their homes without warning.
