The Environmental Protection Agency says it has found no evidence that hydraulic fracturing — better known as fracking — has led to widespread pollution of drinking water. The oil industry and its backers welcome the long-awaited study, while environmental groups criticize it.
“We found the hydraulic fracturing activities in the United States are carried out in a way that has not led to widespread systemic impacts on drinking water resources,” says Tom Burke, science adviser and deputy assistant administrator of the EPA’s Office of Research and Development. “In fact, the number of documented impacts to drinking water resources is relatively low when compared to the number of fractured wells,” he adds.
The EPA’s draft assessment was conducted at the request of Congress. “It is the most complete compilation of scientific data to date,” says Burke, “including over 950 sources of information, published papers, numerous technical reports, information from stakeholders and peer-reviewed EPA scientific reports.”
