Oklahoma Ignores Link Between Record Number of Earthquakes and Fracking Wastewater Disposal Wells

Oklahoma fracking earthquakes

As Oklahoma continues to experience more earthquakes than California this year, residents are questioning why regulators haven’t taken any meaningful action to guard against increased seismic activity.

The U.S. Geological Survey (USGS) says that wastewater injection into deep geologic formations, a part of the hydraulic fracturing (fracking) process, is a likely contributing factor to this increase in quakes. The phenomenon, known as “injection-induced seismicity,” has been documented for nearly half a century, according to the USGS.

The rate of earthquakes in Oklahoma has increased remarkably since October 2013 — by about 50 per cent — significantly increasing the chance for a damaging magnitude 5.5 or greater quake in central Oklahoma,” says the USGS report.

Angela Spotts is one of many Oklahoma residents who is wondering why no meaningful action has been taken to safeguard residents.

It is kind of like an assault. You feel like you are being sacrificed for this gold they are pulling out of the ground. And you start meeting people that are getting sick,” Spotts, a member of Stop Fracking Payne County, told DeSmogBlog. “It is the tobacco industry all over again.”

California Farmers File Suit Alleging Oil Companies' Faulty Wastewater Injection Caused Crop Loss

A farming company in Kern County, California, has sued four oil producers over claims that their faulty wastewater injection methods led to the contamination of groundwater it uses for irrigation.

Palla Farms LLC, a ninety-two-year-old family farm operation, says it had to tear out hundreds of cherry trees due to high levels of salt and boron in the groundwater it has used to irrigate its crops for the past 25 years. The company claims its almond orchard has also experienced production declines.

Palla Farms' suit alleges that the four oil companies—Crimson Resource Management Corp., Dole Enterprises Inc., E&B Natural Resources Management Corp. and San Joaquin Facilities Management Inc.—violated state environmental regulations when disposing of produced water, drilling mud, and flowback water from fracking, which led to the contamination of the groundwater.

The Bakersfield Californian has the details on the allegations:

California Orders Emergency Shutdown Of Fracking Wastewater Injection Sites Over Fears of Contaminated Aquifers

California officials ordered an emergency shutdown of 11 oil and gas waste injection sites in Kern County earlier this month, fearing they may be contaminating sources of drinking water that are sorely needed in the drought-stricken state.

No contamination has actually been found in any drinking or irrigation water, but, according to The Bakersfield Californian, “Pollution has not been ruled out… as regulators conduct site inspections and await test results and other information from the companies” that were operating the injection sites.

State officials are reviewing not just the 11 wells that were ordered to be shut down but as many as 100 more in northeast and east Bakersfield, CA over fears that fracking fluids and “produced waters” (the toxic and potentially radioactive fluids that come up with oil) may be leeching into potential sources of potable water.


As ProPublica reported, California's Division of Oil and Gas and Geothermal Resources issued the shutdown orders on July 7 to seven different energy companies, saying that they may have injected wastewater into aquifers that could be a source of drinking water, which “poses danger to life, health, property, and natural resources.”

A review of wastewater injections sites is long overdue in California. The state had exempted as many as 100 aquifers from environmental protection after they were found to contain water unfit for consumption or to be too deep to make their use feasible. But a 2011 report released by the U.S. Environmental Protection Agency found significant shortcomings with how the state was managing its wastewater injection program:

USGS Study Connects Earthquake Risk To Wastewater Injection, Fracking Advocates Say, "Who Cares?"

A new study out in Science by US Geological Survey scientist William Ellsworth links earthquakes to wastewater injection sites. These earthquakes, thought to be caused by pressure changes due to excess fluid injected deep below the surface, are being dubbed “man-made” earthquakes.

It's not the first time scientists have used that moniker, as earthquakes have been associated with other industrial operations that mess with underground formations such as surface and underground mining or dams that impound water into reservoirs.

Yet, in more recent years, we're seeing more and more of them,

“The number of earthquakes has increased dramatically over the past few years within the central and eastern United States. More than 300 earthquakes above a magnitude 3.0 occurred in the three years from 2010-2012, compared with an average rate of 21 events per year observed from 1967-2000.”
 


Many likely know that “wastewater” is a byproduct of many fossil fuel processes. It can come from raw material itself or is a leftover from purification steps during the extraction and processing phases of fuel production.
