Robert Howarth, an ecologist and evolutionary biologist, and Anthony Ingraffea, a civil and environmental engineer, reported that fracked wells leak 40 to 60 percent more methane than conventional natural gas wells.

Not exact matches

The nonprofit investigative news organization Pro Publica has reported numerous confirmed health and safety problems related to drilling and fracking, including a house explosion near Cleveland, Ohio, after gas leaked into the home's water well.

If the cement casing that surrounds a fracking well is made incorrectly, natural gas can leak along its sides or through cracks, releasing harmful gases like methane to the environment.

Since then, we have all learned a lot about the risks of fracking — about how the toxic chemicals used can migrate into drinking water, about how methane can leak out of well casements, about the danger of disposing of billions of gallons of polluted wastewater the process produces.

Improperly drilled wells or faulty well casings can leak fracking fluids and methane gas into nearby aquifers and water wells.

But Clarens says fracking fluids could theoretically leak into aquifers, because the wells must be dug through shallow layers where the aquifers lie in order to reach shales.

Efforts to regulate existing wells would be more useful if EDF were to also come out against an expansion of fracking: We will, after all, continue to produce natural gas in this country (if nothing else, massive quantities are required to produce fertilizer) and there is no need to leak more methane than we have.

The IEA has a longish set of «Golden Rules» that could make fracking a better environmental bet, and McCabe highlights the two most important of them: (1) Eliminate leaks completely from the natural gas production process, and (2) use carbon sequestration to substantially reduce carbon emissions from gas - fired electrical plants.
