Some commercial farms in California came up with their own solution to the drought, and it’s not pretty. They decided to use recycled oil industry waste water to grow their produce. Chevron Oil Company treats 21 million gallons of waste water per day and sells it to farmers, who in turn use it to water 45,000 acres of crops in one of the country’s primary produce-growing areas.

It’s like something used in third world countries that we scorn for their unsafe practices:

In most developing countries wastewater treatment systems are hardly functioning or have a very low coverage, resulting in large scale water pollution and the use of very poor quality water for crop irrigation especially in the vicinity of urban centres. This can create significant risks to public health, particularly where crops are eaten raw.

But it’s happening right here.

Recycled irrigation water has been used to some degree for decades, but the testing has been limited to naturally occurring toxins, like salt and arsenic. Officially, no testing is done for the chemicals used in oil production. While farmers test crops for pests or diseases, they don’t test them for chemicals that may have absorbed through the roots from water. They figure that the water authorities are looking out for that. So basically, everyone expects that someone else does the testing, and no one does the testing. Nuts, citrus, and grapes may be highly contaminated but no one knows for sure.

Yummy, right?

This is what independent testing of the oil industry waste water showed

One environmental group took it upon themselves to test samples of the treated irrigation water. Water Defense, an advocacy group founded by actor Mark Ruffalo, discovered something very unsettling.

Mark Smith, the scientist who took samples for Water Defense, has been a consultant for the EPA on more than 50 oil spills. He took samples from areas of the canal that were publicly accessible and put them through comprehensive testing.

He found acetone and methylene chloride. These are solvents used to remove grease from equipment and soften crude oil, and said that the concentrations in the water were higher than he had seen at oil spill disaster sites. He also found C20 and C34, hydrocarbons found in oil.
