According to the latest research by the U.S. Geological Survey (USGS), there’s a reason that 70% of frac sand, used in fracking, comes from Wisconsin and Minnesota. The silica (or sand) mined in those Great Plains states has the best characteristics to be used in fracking. But there are other places–even places in the Marcellus/Utica–that are being mined for silica used for fracking. In an article titled “Frac Sand Sources in the United States” published in the May 2015 issue of Rock Products magazine, USGS researchers describe what makes good frac sand and where, in the Lower 48 U.S. state, it’s being mined commercially.
