California regulators are not doing enough to protect groundwater from wastewater injection by the energy industry, according to a new report by KQED. “Oil companies in California produce tons of wastewater. On average, for every barrel of oil, a California oil well produces 19 barrels of water, often laden with salts, trace metals and chemicals like benzene,” the report said. To discard the wastewater, energy companies pump it into the ground.
