Feds: EPA fails to protect water from oilfield contamination

FILE - In this Jan. 15, 2015 file photo, a private property sign hangs on the fence of a shut-down injection well next to an almond orchard owned by Palla Farms in Bakersfield, Calif. Palla Farms had filed suite blaming several oil companies for contaminating the local groundwater and killing cherry trees. A federal review says the U.S. Environmental Protection Agency is failing to protect drinking water reserves from oilfield contamination. The U.S. Government Accountability Office review follows disclosures that California allowed oil companies to dump wastewater into some federally protected supplies of drinking-water.
