Associated Press: February 5, 2015
Regulators in California, the country’s third-largest oil-producing state, have authorized oil companies to inject production fluids and waste into what are now federally protected aquifers more than 2,500 times, risking contamination of underground water supplies that could be used for drinking water or irrigation, state records show.
While some of the permits go back decades, an Associated Press analysis found that nearly half of those injection wells — 46 percent — were permitted or began injection in the last four years under Gov. Jerry Brown, who has pushed state oil and gas regulators to speed up the permitting process. And it happened despite warnings from the U.S. Environmental Protection Agency since 2011 that state regulators were failing to do enough to shield groundwater reserves from the threat of oilfield pollution.
In California, “we need a big course correction. We need to get the system back in compliance,” said Jared Blumenfeld, regional administrator for the EPA. “Californians expect their water is not being polluted by oil producers … This poses that very real danger.”
The injections are convenient to oil companies because drilling brings up 13 gallons of wastewater for every gallon of petroleum. And one of the easiest disposal methods is simply to send that waste back underground.
