Before everyone loses there mind, because this story has oddly been on blast 2 weeks after the incident:
VC is a gas a room temperature. None of the VC cars were ruptured in the crash. They were vented and ignited by workers to avoid explosion. Burning VC produces carbon oxides, HCl, phosgene, and formaldehyde. HCl, Phosgene become hydrochloric acid in the atmosphere. The total amount of hydrochloric acid this could possibly produce would hardly register in the water table. Formaldehyde would be trace too, similar to fruits and vegetables.
