WASHINGTON — Hydraulic fracturing to drill for oil and natural gas poses a risk to drinking water in some circumstances, but a lack of information precludes a definitive statement on how severe the risk is, the Environmental Protection Agency says in a new report that raises more questions than answers.
The report removes a finding from a draft issued last year indicating that fracking has not caused “widespread, systemic” harm to drinking water in the United States. Industry groups hailed the draft EPA study as proof that fracking is safe, while environmentalists seized on the report’s identification of cases where fracking-related activities polluted drinking water.

Hydraulic fracturing of shale formations to extract natural gas has no direct connection to groundwater contamination, according to a study by the Energy Institute of the University of Texas at Austin.
The study, released at a meeting of the American Association for the Advancement of Science in Vancouver, British Columbia, found that many problems ascribed to fracking actually have other causes, such as “casing failures or poor cement jobs.”
