For days, authorities have been telling residents of the area around East Palestine, Ohio, that it is safe to return home after a 150-car train carrying hazardous chemicals derailed Feb. 3.
The Ohio Department of Natural Resources said the chemical spill resulting from the derailment had killed an estimated 3,500 small fish across 7½ miles of streams as of Wednesday.
For some people who live near the derailment site, the reports continue to spur fear that they and their animals might be exposed to chemicals through the air, water and soil.
The Ohio Department of Agriculture said the risk to livestock remains low.
