But that’s common for this corner of the Central Valley, where arsenic often leaches into the water from the native rocks. The drinking wells may have been protected by distance, said Jonathan Bishop, chief deputy director of the State Water Resources Control Board. Even when the oil companies injected wastewater into an aquifer used for drinking and irrigation, the injection wells were drilled deeper than the drinking wells.</div><div style="margin-top: 0px; margin-bottom: 0px; padding-bottom: 24px; border: 0px;
