On Tuesday, California regulators ordered a dozen oil and gas wells to cease production over concerns that the wells may be contaminating groundwater.
Oil companies Chevron Corp. and Linn Energy LLC voluntarily stopped production at 10 of the Central Valley wells, while the two other wells were given cease-and-desist orders. While there is no evidence of drinking water contamination yet, the wells are located within a mile of the surface and within 500 feet of a water supply.
“As we’ve said before, the protection of California’s groundwater resources — as well as public health — is paramount, particularly in this time of extreme drought,” said Steven Bohlen, head of oil, gas and geothermal resources for the California Department of Conservation. “Halting injection into these wells is a significant step toward that goal.”
