A 2009 report on modern shale gas by the
Groundwater Protection Council, "Modern Shale Gas Development in the
United States: A Primer," stated that
“[t]he amount of water needed to drill and fracture a horizontal shale gas well
generally ranges from about 2 million to 4 million gallons, depending on the
basin and formation characteristics.” A 2010 Harvard study found that, on average, water consumption for natural
gas produced through fracking ranges from 0.6 to 1.8 gallons of water per MMBtu
(Mielke, Anadon and Narayanamurti 2010).
How can this possibly be justified? Ed.
