Wastewater from hydraulic fracking has been in the news quite a bit lately and not for good reason.  Concerns over wastewater injections creating or inducing earthquakes and contamination from chemicals in fracking wastewater are growing.

In mid-November, Uproxx.com released a story about wastewater from oil production being sold to drought-stricken California farmers in Kern County at a discount for use on food crops.¹ The main concern is the chemicals in the wastewater are considered “proprietary.” Therefore no one really knows what chemicals are being applied to our foods and whether or not they are making their way into the food chain.  Since California grows 40% of our nation’s food, should we be concerned?

Andrew Grinberg, Special Project Manager at Clean Water Action, considers the application of oil wastewater on Kern County crops a “chemical experiment on our food supply.”² Adam Scow, California Director of Food and Water Watch, believes “it’s a bad idea to use water contaminated with chemicals, such as benzene, on crops and to recharge groundwater.”³ This practice has apparently been going on for 20 years.

This isn’t the first time the oil and gas industry has been under scrutiny in California.  In 2015, the California’s Department of Conservation, the Division of Oil, Gas and Geothermal Resources came under fire because they “inadvertently allowed oil companies to inject wastewater — from fracking and other production operations — with high levels of benzene, a carcinogen, into hundreds of wells in protected aquifers, a violation of federal law.”⁴ The EPA found this oversight of the Safe Drinking Water Act “shocking”.⁵

In Oklahoma and southern Kansas underground wastewater injections from hydraulic fracking processes have been linked to earthquakes.  A Forbes.com article noted “some areas in north-central Oklahoma and southern Kansas now have hazards from fracking-related induced earthquakes that are similar to parts of California where earthquakes are caused by natural tectonic forces like plate collisions and volcanism.”⁶

Residents of those two states have responded to the tremors by purchasing earthquake insurance. Insurance purchases in Oklahoma are “up 500% from just five years ago in 2011.”⁷ Unfortunately, coverage of man-made earthquakes is a grey-area for many insurance companies. So it’s best to do some digging and confirm any policy or endorsement covers earthquakes resulting from fracking activities.⁸

The oil and gas industry is a Titan of the American economy. For every barrel of oil produced, 15 barrels of wastewater are created.⁹ Given the immense volumes of oil, gas and the resulting wastewater produced, it is imperative we find better solutions for disposal. We can’t continue to pretend that current techniques aren’t impacting the environment. Clearly, they are and its time for a change.
