Irrigation water appears to be a major loophole in the USDA's organic food safety program.
The US Department of Agriculture's organics standards, written 15 years ago, strictly ban petroleum-derived fertilizers commonly used in conventional agriculture. But the same rules do not prohibit farmers from irrigating their crops with petroleum-laced wastewater obtained from oil and gas wells—a practice that is increasingly common in drought-stricken Southern California.
As I reported last month, oil companies last year supplied half the water that went to the 45,000 acres of farmland in Kern County's Cawelo Water District, farmland that is owned, in part, by Sunview, a company that sells certified organic raisins and grapes. Food watchdog groups are concerned that the state hasn't required oil companies to disclose all the chemicals they use in oil drilling and fracking operations, much less set safety limits for all those chemicals in irrigation water.
