Train derailments cause hazardous material spills in multiple US states.

Two BNSF trains derailed in separate incidents in Arizona and Washington state on Thursday, with the latter spilling diesel fuel on tribal land along Puget Sound. The derailment in Washington occurred on a berm along Padilla Bay, on the Swinomish tribal reservation near Anacortes. Most of 5,000 gallons of spilled diesel fuel leaked on the land side of the berm rather than toward the water, according to the state Ecology Department.
