On Feb. 3, 2023, a 50-car freight train transporting hazardous materials derailed in East Palestine, Ohio. On Feb. 6, fears over the instability of one of those chemicals led the operator, Norfolk Southern Railroad, to begin a "controlled release" of the toxic chemical vinyl chloride. The move prompted the evacuation of the immediate area around the derailment and led to a fiery plume of chemicals.
Just days later, residents were told it was safe to return. These statements were greeted with significant skepticism. A commonly cited challenge to assurances of no safety risk was reports of dead fish in proximity to the chemical release. Several videos showing this event went viral in the derailment's aftermath. These videos — at least all of those filmed from the same small brook in East Palestine — are authentic.
One video, shared on TikTok and other platforms, shows workers for an environmental sciences company working in a brook and collecting dead fish:
Another shared on Twitter shows this same location, identifying it as Leslie Run:
Here, Snopes addresses two questions. First, do these videos authentically show a location close to the East Palestine train derailment? And second, do these videos show real events that occurred after the derailment? The answer to both questions is yes.
The videos, along with their descriptions, provide enough information to make a precise geolocation of their location in Google Maps:
Second, the presence of dead fish, as well as environmental workers working in Leslie Run, was widely reported by local news media at the time, confirming the events as having occurred after the chemical release. One example comes from Pennsylvania-based CBS Pittsburgh, reporting on Feb. 6, 2023:
Because local reporting confirms the chronology and because geolocation of the brook is possible, these viral videos authentically show dead fish in close proximity to the East Palestine derailment and subsequent chemical release.
