A new interactive map shows hydraulic fracturing, or "fracking," is flourishing in U.S. areas where water is already scarce — a potentially bad sign for Ohio counties that are allowing the water-intensive drilling process within their own borders.
The map from advocacy group Ceres shows northeast Ohio counties with fracking activity are made up of low, medium-to-high and high stress areas, with most of the identified fracking wells in medium-to-high and high stress areas.
The website explains Ohio's experience is actually better than the national trend: "In the map below, one can see that almost half (47 percent) of shale gas and oil wells are being developed in regions with high to extremely high water stress.
Fracking is a relatively new drilling process that involves pumping millions of gallons of water underground to fracture shale and reveal oil and gas reserves. CityBeat previously covered Ohio's fracking boom in further detail here.
