The natural gas industry defends hydraulic fracturing, better known as fracking, as safe and efficient. Thomas J. Pyle, president of the Institute for Energy Research, a pro-industry non-profit organization, claims fracking has been “a widely deployed as safe extraction technique,” dating back to 1949. What he doesn’t say is that until recently energy companies had used low-pressure methods to extract natural gas from fields closer to the surface than the current high-pressure technology that extracts more gas, but uses significantly more water, chemicals, and elements.
