Someone googled that question: the source of fracking water for the Bakken? See question 50 at FAQs (I occasionally change the numbering, so the number could change; use browser to search water if necessary).
It's the Missouri River for the most part.
Well water is also used.
Through 2011, I believe most water was provided by independent water distributors and, perhaps, the city of Williston municipal water supply. Sometime in 2012/2013, I assume most fracking water will be provided by WAWS. I don't know the specifics on fracking water because I do not follow it closely. There is not a supply issue regarding water for fracking in the Bakken.
There is more than enough water in the region for fracking. The one thing the Bakken is not short of is water, regardless of what folks may tell you. One inch of water off the top of the Sakakawea Lake (the Missouri River behind the Garrison Dam) will provide all the water that is needed for 5,000 Bakken wells annually; and the operators can drill a max of about 2,000 wells each year. So don't let anyone suggest there is not enough water. Period. Dot.
For more, look at the tag "WAWS" or "water" below -- at the very bottom of the blog where the labels/tags are kept.
