The governor of Ohio has lifted an evacuation order for residents of East Palestine.
That is after a train derailment last week caused a life-threatening chemical spill.
Five train carriages were carrying vinyl chloride, which can be fatal when inhaled, and has been linked to cancer.
Emergency workers performed a controlled burn of the chemical on Monday, but residents remain worried about long-term contamination.
