DEER PARK, Texas (AP) — Toxic wastewater used to extinguish a fire following a train derailment in Ohio is headed to a Houston suburb for disposal. “This injection, in some cases, is usually 4,000 or 5,000 feet down below any kind of drinking water aquifer,” said Guillen, who is also a professor of biology and environmental science at the University of Houston-Clear Lake. Both Guillen and Deer Park resident Tammy Baxter said their greatest concerns are transporting the chemicals more than 1,300 miles (2,090 kilometers) from East Palestine, Ohio; to Deer Park, Texas
