Air pollution also extends beyond the immediate drilling site and transportation route, since a by-product of natural gas drilling is methane gas, one of the worst greenhouse gas pollutants contributing to climate change. Transport of the waste poses a contamination risk outside the actual well location. Storage for the waste water can take place either on site, in an injection well, or in open air ponds in the surrounding areas. Since each well can require up to 8 million gallons of water, and up to 40,000 gallons of chemicals, a well site may need up to 2000 tanker truck trips, per frack. The well location where drilling takes place is only one piece of the frack puzzle. Large volume water use in water-deficient regionsÄue to the multitude of potential health and environmental impacts of hydrofracking source contamination can be complicated.Methane pollution and its impact on climate change. ![]() ![]() Howarth, Anthony Ingraffea, & Terry Engelder. 15, 2011, Natural Gas: Should fracking stop?, by Robert W.
