Nearly half of Iowa crude oil spill contained, BNSF says

Workers have contained nearly half of the crude oil spilled near Rock River in northwest Iowa over the weekend following a freight train derailment on Friday, BNSF Railway Co said.

About 100,000 gallons had been hemmed off using booms out of the estimated 230,000 gallons spilled, BNSF said in a statement on Saturday. The spill has raised concerns about drinking water downstream. The company did not respond to questions on Sunday about the progress of the cleanup.

No one was hurt in the derailment, in which 32 cars came off the rails, 14 of which leaked at least some of their contents, BNSF said. The derailment happened south of Doon, a city of a few hundred people. The cause has not been confirmed, although Iowa Governor Kim Reynolds attributed it to an intense storm and flash flooding in an emergency proclamation issued by her office on Saturday.
