The State of Michigan has reached a deal with the city of Flint, with the state agreeing to pay nearly $100 million to replace water lines to thousands of homes whose water has been poisoned by lead.

Flint’s water crisis began in 2014, after the unelected, state-appointed emergency manager for the city of Flint changed the source of the drinking water to the Flint river in order to try to save money. The river water corroded Flint’s pipes, causing toxic lead to leach into the city’s drinking water.

Officials say Flint’s water is still unsafe to drink without a filter — and many residents remain wary of drinking the water at all.
