It's been nearly a month since a Norfolk Southern train derailed and spilled hundreds of thousands of pounds of toxic chemicals into the air, soil and water around East Palestine, Ohio. In the weeks since, authorities have undertaken a massive operation to clean up the hazardous materials.
More than 700 tons of contaminated soil and nearly two million gallons of liquid have been collected from the derailment site, Ohio officials say, with much more left to clean up under the order of the Environmental Protection Agency.
