This study, prepared by the California Council on Science and Technology in partnership with the Pacific Institute and Lawrence Berkeley National Laboratory, consists of three volumes. It explores well stimulation treatments in California; the risks these technologies pose to water, air, seismic activity, wildlife, plants, and human health; risks by geographic region within the state; and areas where there are information gaps. It also provides recommendations to improve practices and regulations for oversight of oil and gas development in the state.
