A freight train carrying crude oil from the Alberta tar sands to Oklahoma derailed on June 22nd near Doon, Iowa. Here are some details:
- 32 tank cars derailed.
- 14 of them are leaking.
- The total volume of the spill is 230,000 gallons (for reference the capacity of a typial DOT-111 tank car is 34,500 gallons, so the total spill is equivalent to about 6 or 7 cars).
- Much of the oil has been contained with booms, but some of it has entered the local river system.
- The cause of the event is not known. Speculation is the floodwaters may have eroded the soil beneath the track.
