As California farmers face a fourth year of the state’s historic drought, they’re finding water in unexpected places — like Chevron’s Kern River oil field, which has been selling recycled wastewater from oil production to farmers in California’s Kern County. Each day, Chevron recycles and sells 21 million gallons of wastewater to farmers, which is then applied on about 10 percent of Kern County’s farmland. And while some praise the program as a model for dealing with water shortages, environmental groups are raising concerns about the water’s safety, according to a recent story in the Los Angeles Times.
Tests conducted by Water Defense, an environmental group founded by actor Mark Ruffalo in 2010, have found high levels of acetone and methylene chloride — compounds that can be toxic to humans — in wastewater from Chevron used for irrigation purposes. The tests also found the presence of oil, which is supposed to be removed from the wastewater during recycling.
“All these chemicals of concern are flowing in the irrigation canal,” Scott Smith, chief scientist for Water Defense, told ThinkProgress. “If you were a gas station and were spilling these kinds of chemicals into the water, you would be shut down and fined.”
