Toxic wastewater used to extinguish a fire following a train derailment in Ohio is headed to a Houston suburb for disposal. “I and my office heard today that ‘firefighting water’ from the East Palestine, Ohio, train derailment is slated to be disposed of in our county,” Harris County Judge Lina Hidalgo said in a Wednesday statement. “Our Harris County Pollution Control Department and Harris County Attorney’s have reached out to the company and the Environmental Protection Agency to receive more information,” Hidalgo wrote.
