3 Billion Gallons Of Oil Industry Wastewater Injected Illegally Into California Aquifers



From the Center for Biological Diversity comes some troubling news:
Almost 3 billion gallons of oil industry wastewater have been illegally dumped into central California aquifers that supply drinking water and farming irrigation, according to state documents obtained by the Center for Biological Diversity. The wastewater entered the aquifers through at least nine injection disposal wells used by the oil industry to dispose of waste contaminated with fracking fluids and other pollutants.

High levels of arsenic, thallium and nitrates were also found in water-supply wells around waste-disposal locations. These, of course, have yet to be tested to find out the true nature of their relationship to the waste-management facilities nearby.
The state’s Water Board confirmed beyond doubt that at least nine wastewater disposal wells have been injecting waste into aquifers that contain high-quality water that is supposed to be protected under federal and state law.
Thallium is an extremely toxic chemical commonly used in rat poison. Arsenic is a toxic chemical that can cause cancer. Some studies show that even low-level exposure to arsenic in drinking water can compromise the immune system’s ability to fight illness.
“Arsenic and thallium are extremely dangerous chemicals,” said Timothy Krantz, a professor of environmental studies at the University of Redlands. “The fact that high concentrations are showing up in multiple water wells close to wastewater injection sites raises major concerns about the health and safety of nearby residents.”

The findings are a cause for serious anxiety. The extent of the testing that is still needed is even more distressing. This is yet another painful example of why caution must be exercised when stepping forward into the lucrative fracking industry.
