Why Are California Farmers Irrigating Crops With Oil Wastewater?

Some concerning facts here about our food and what potential danger the food from this area may have.

In the last three years, farmers in parts of California's Central Valley irrigated nearly 100,000 acres of food crops with billions of gallons of oil field wastewater possibly tainted with toxic chemicals, including chemicals that can cause cancer and reproductive harm, according to an Environmental Working Group (EWG) analysis of state data.Since 2014, oil companies reported that they used more than 20 million pounds and 2 million gallons of chemicals in their operations, including at least 16 chemicals the state of California classifies as carcinogens or reproductive toxicants under the state's Proposition 65 law
