The Science of Flint's Water Crisis

The Flint water crisis began in 2014 when the city switched its water supply to the Flint River, leading to widespread lead contamination and bacterial outbreaks. The lack of corrosion control and high chloride levels exacerbated the problem, resulting in significant health risks, including Legionnaires' disease. Historical use of lead pipes and inadequate testing protocols contributed to the crisis. The situation highlighted the importance of proper water treatment and the consequences of ignoring scientific guidelines, leading to a costly recovery process and loss of public trust.
