The Environmental Protection Agency will focus its national study of hydraulic fracturing on seven areas in five states, but will exclude the two Wyoming gas fields where agency researchers have already collected some of the most in-depth data on drilling's environmental impacts.

The study – which was announced last March, without specifics on research sites – will investigate alleged water contamination from drilling in five areas in Texas, Colorado, North Dakota and Pennsylvania. It also will encompass cradle-to-grave research projects in Pennsylvania and Louisiana, where the agency will track drilling's effects on water quality from before the drill bit hits the ground to after hydraulic fracturing has been performed.
