Hundreds of fish were discovered dead in a stream running through East Palestine, Ohio, after a Norfolk Southern Railway train derailed more than a week ago.

Officials decided to conduct a controlled burn of the toxic chemicals contained within the train cars to prevent an explosion that could potentially cause more harm. The burn released an ominous plume of black smoke in the air. Five of the train cars contained vinyl chloride, a human carcinogen.

An evacuation order has since been lifted, but residents are still recognizing the devastating effects of the derailment, specifically the impacts on wildlife.

Two days after the controlled burn began on February 6, Pittsburg news station KDKA reported that hundreds of fish were found "belly up" in the Leslie Run stream.
