Oil wastewater, possibly tainted with toxic chemicals, is being used in Kern County for agriculture and to recharge regional aquifers. That’s the finding of a study released this week that examined the chemicals contained in the wastewater that comes up when oil is produced. The report concludes that current testing methods aren’t detecting many of the chemicals in the water. A staff scientist at the Center for Biological Diversity says the practice should be halted until more is known about how the use oil wastewater could impact human health and the environment.
