Keystone XL Pipeline Controversy

Conventional crude oil tends to remain on top of water during a spill. Enbridge's Line 6B was carrying diluted bitumen, or dilbit -- petroleum so thick that it must be mixed with chemicals, frequently including the carcinogen benzene, to flow through pipelines. In the Kalamazoo River, the bitumen gradually sank to the river's bottom, where normal cleanup techniques and equipment were of little use.

Ceresco Dam, which was inundated with oil, had to be dredged in fall 2010.

Diluted bitumen is the same type of oil that could someday be carried by the much-debated Keystone XL pipeline, if that project is approved.
