Final answer:
The Flint water crisis is a result of the city switching its water supply to the Flint River, which caused lead to leach from the aging water pipes.
Step-by-step explanation:
The Flint water crisis is a result of several factors. The city of Flint switched its water supply to the Flint River in an effort to save money. However, the river water was corrosive and caused lead to leach from the aging water pipes, resulting in elevated levels of lead in the water. The high percentage of lead pipes in Flint, combined with the corrosive water, led to a significant decline in water quality. This issue disproportionately affected low-income communities and communities of color, exacerbating issues of systemic racism.
