A new Environmental Working Group investigation reveals that the fluids used to frack California oil wells contain a toxic stew of chemicals that can cause cancer, disrupt hormones and harm the reproductive system.
The investigation found that drillers have pumped nearly 200 different chemicals into almost 700 oil wells – some of them dangerously close to sources of drinking water. The frackers also injected directly into some of our drinking water aquifers, and the State of California has not punished them. These chemicals can not only contaminate drinking water, but pollute the air and soil as well. Of the chemicals added to fracking fluid in California, 15 are found on the state’s official list of substances that can cause cancer or reproductive harm. A dozen are listed as pollutants known to cause cancer or other harm.
According to the report of the chemicals used in fracking:
- 15 listed under California’s Proposition 65 as known causes of cancer or reproductive harm
- 25 likely to contain impurities of Proposition 65-listed chemicals
- 5 that the European Union has associated with an increased risk of cancer
- 6 associated with reproductive harm
- 3 linked to clear evidence of hormone disruption
- 12 listed under the federal Clean Air Act as Hazardous Air Pollutants known to cause cancer or other harm
- 93 associated with harm to aquatic life
