The Flint water crisis began in 2014 when the city of Flint, Michigan switched its water supply from Lake Huron to the Flint River to save money. The river water was not properly treated, leading to corrosion of the city's aging pipes and leaching of lead into the drinking water. Residents began to notice changes in water color, taste, and health issues. As a result, many people in Flint experienced serious health problems, including lead poisoning, which can cause long-term developmental issues in children. The crisis highlighted failures in government oversight and raised awareness about the importance of safe drinking water across the United States.
