We’re finding out what’s in fracking wastewater, and it ain’t pretty

On so many issues, California is the green leader, showing other states how it should be done better. But better is not necessarily the same thing as flawless. Right now, California is doing a better job of regulating fracking than any other state that allows it — but, of course, many local activists would rather the state just banned it, as New York has.

The federal government doesn’t require fracking companies to disclose the chemicals they use in their operations, and it has failed to produce data on the safety of fracking. Five years after the U.S. EPA announced plans to study fracking’s effect on drinking water, industry resistance has thwarted the effort. It’s up to states to require fracking operations to disclose what chemicals they are using and to find out if those chemicals are getting into the public water supply when frackers inject their wastewater underground.

In 2013, California Gov. Jerry Brown (D) signed a law requiring disclosure of chemicals used in fracking and setting up monitoring for air and water quality near unconventional drilling sites. No other state has adopted as comprehensive a system for finding out what’s actually in fracking wastewater.

The found a carcinogenic soup full of volatile organic compounds that have been associated elsewhere with an array of unpleasant health effects. From the report:

Petroleum chemicals, heavy metals and radioactive elements, plus high levels of dissolved solids, are among the pollutants found in fracking wastewater samples tested under the new disclosure program.They include benzene, chromium-6, lead and arsenic — all listed under California’s Proposition 65 as causes of cancer or reproductive harm. Nearly every one of the 293 samples tested contained benzene at levels ranging from twice to more than 7,000 times the state drinking water standard. The wastewater also carried, on average, thousands of times more radioactive radium than the state’s public health goals consider safe, as well as elevated levels of potentially harmful ions such as nitrate and chloride.
