SAN FRANCISCO (AP) - Environmental groups are asking federal regulators to curb oilfield dumping into underground water reserves.
The Natural Resources Defense Council and Clean Water Action made the request Wednesday in a petition to the U.S. Environmental Protection Agency.
The groups accuse the EPA of being too lax in granting oil companies permits to inject wastewater and other material into the country's natural below-ground water supplies.
Environmental groups charge regulators are risking contamination of potential supplies of drinking water. The oil industry says there's no evidence of drinking water being contaminated so far.
Wednesday's petition asks for a freeze on new permits. Last year, regulators in California acknowledged their own shortfalls had allowed oilfield contamination of some federally protected underground water reservoirs.
The EPA did not immediately respond to a request for comment.
