City of Flint

Flint's water crisis was not an unavoidable consequence of old pipes or a single mistaken laboratory result. A state-controlled city changed water source, an unprepared plant distributed water without the corrosion control that had protected the network, and the institutions with authority to stop the exposure did not act when residents and technical evidence warned them. Later water results, pipe replacement, civil settlements and the end of a federal emergency order document substantial repair. They also show why public-water accountability requires more than a compliant system-wide percentile: it requires control records, household-level protection, credible health follow-up and proof that residents can challenge official assurances before harm becomes a crisis.
