North Dakota part of EPA fracking study
BISMARCK, N.D. (AP) — An area in western North Dakota will be included in a study by the Environmental Protection Agency on potential impacts to water sources from hydraulic fracturing that's used to retrieve oil and natural gas from deep underground.
The EPA said Thursday that it has chosen seven sites for the study, including Dunn County and the Kildeer area in North Dakota.
Hydraulic fracturing, or fracking, is a process using pressurized fluid and sand to break open oil and gas bearing rock.
Other tests sites in the congressionally mandated study are in Texas, Louisiana, Pennsylvania, and Colorado.
The EPA said two sites will study the fracking process throughout the lifecycle of a well. The other five studies, including those in North Dakota, will examine areas where fracking has already occurred.
