E.P.A. Reviewing Risks of Gas Extraction after reports hydraulic fracturing, blasting with chemicals pose health risks.
Fears of fracking’s impact on water supplies prompted regulators overseeing the Delaware Water Basin to curtail gas exploration until the effects could be more closely studied. New York State lawmakers are contemplating a moratorium.
At the national level, in addition to the E.P.A. study, a Congressional investigation of gas drilling and fracturing, led by House Energy and Commerce Committee, intensified last week with demands sent to several companies for details on their operations — particularly how they handled the slurry of water and chemicals that flowed back from deep within a well.
A renewed, if unlikely, push is also under way to pass federal legislation that would undo an exemption introduced under the Bush administration that critics say freed hydraulic fracturing from regulation under the Safe Drinking Water Act.
Last month, Wyoming introduced some of the nation’s toughest rules governing fracturing, including provisions that require companies to disclose the ingredients in their fracturing fluids to state regulators — though specifically not to the public.
