On Feb. 3, 2023, a Norfolk Southern train carrying hazardous chemicals derailed in East Palestine, Ohio. Three days later, on Feb. 6, the company began a "controlled release" of the chemicals after fears of a large explosion began to grow.
After the crash, local residents and communities expressed health and environmental concerns. Viral videos and photographs spread claiming to show the crash and its aftermath, including videos of dead fish near the crash site. We analyzed those, and also checked claims made about how many people live in the larger region surrounding where the crash occurred, and how they might be impacted.
