History

Historical Context

In August 1978 President Jimmy Carter declared a federal health emergency at Love Canal, leading the EPA to evacuate residents—including 410 students—from the Niagara Falls neighborhood. The crisis spurred the 1980 Superfund law, mandating public disclosure of hazardous-waste sites. That precedent underlies New York City’s release of 9/11 air-quality records, a step backed by Mayor Zohran Mamdani.
