Regarding the train derailment in Ohio and the shipment of contaminated soil to Michigan for treatment…Vinyl Chloride (VC) is a highly volatile and carcinogenic chemical. If it was actually in the soil that was being transported it would have been getting released to the atmosphere during the entire transport unless it was entirely sealed up, which it probably wasn’t. Every transfer of the material would release more VC into the atmosphere. The article mentions washing with water and allowing the contaminant to evaporate. It’s VC, it is going to evaporate whether it is in water or not. The only way to treat something like this is by incineration at the site of the spill or using microbes or chemical reactions to break it down in tanks, again on site. They make equipment for such onsite treatment. One shouldn’t be hauling it all over the place.
