Because the Marcellus Shale is a tight rock formation, 4 to 7 million gallons of water are required to fracture each well. That sounds like a lot
of water to be drawn from smaller tributaries around the Susquehanna River basin, especially when you consider that almost 2,000 wells were
permitted for drilling in 2009 (DEP Bureau of Oil & Gas Management)!
So who regulates how much water can be used? How is the amount of water that can be safely withdrawn determined? How does the gas industry’s water use compare to other industries, or recreational uses in Pennsylvania?

What impact would the removal of 4 to 7 million gallons of water have on:
How might the removal of 4 to 7 million gallons of surface water change the quality of the habitat for the animals/plants that live within a waterway?
Does surface water use for the natural gas industry vary across the Marcellus Region? Use USGS’s water use data for mining activities (Table 11, 2000 and 2005) to compare the annual volume of water withdrawals in PA, NY, OH, and WV.
