In East Palestine, Ohio, newly released data shows soil around the site of February’s Norfolk Southern train derailment contains levels of dioxin hundreds of times higher than what’s considered safe. That’s according to The Guardian, which had the data reviewed by former EPA officials and other chemical experts, who said dioxins found in East Palestine were extremely concerning, even if they’re below the federal cleanup threshold. The findings also contradicted assertions by the EPA, which told Congress last week dioxin levels were “very low.” In 2010, when the EPA found dioxin poses cancer risks, the agency tried to have those limits lowered, but the Obama administration kept the higher threshold in place.
