EPA says pollution may be linked to gas wells
Fracking may have tainted water in Wyo.
The U.S. Environmental Protection Agency announced yesterday for the first time that fracking - a controversial method of improving the productivity of oil and gas wells - may be to blame for causing groundwater pollution. The draft finding could have significant implications while states try to determine how to regulate the process. Environmentalists characterized the report as a significant development though it met immediate criticism from the oil and gas industry and a U.S. senator.
