Laura Grace Weldon takes a careful, thorough look at an issue we should all be learning as much about as possible.
A few quotes—
Re safety and long-term effects:
But technically, assertions that fracking is safe are largely true. That’s because industry and government regulatory agencies use the term “fracking” only as it relates to the actual process of pumping fluids into the ground to break apart rock. So when they make claims about fracking safety, they don’t include what happens while drilling, constructing the well, setting off explosions, dealing with blowouts or well fires, storing waste water in open containment basins, vapors emitted from condensate tanks, open flaring to burn off gasses, transporting waste, injecting waste water into deep disposal wells, or at any point in the future when the wells may leak.
That’s convenient, because a University of Texas study found that these are the activities actually contaminating air, water, and soil. So both sides are “right” in the fracking debate. The industry is correct when they say that fracking is largely safe because of their limited definition of the word. People concerned about the environmental and health consequences lump all activities associated with the process under the term “fracking,” making their claims of risk correct too.
Re land rights:
But local citizens have very little control over fracking. Depending where they live, fracking may occur under cemeteries and in state parks. Some cities as well as colleges are considering lease offers. Despite regulations that normally zone residential areas apart from industrial areas, drilling can take place near homes and schools. Residents in Colorado, Texas, West Virginia, and elsewhere are advocating for stronger regulations to protect schoolchildren from the noise and dust generated by these sites. In some areas drilling sites are only required to be 350 feet from schools and 200 feet from homes. (In New Mexico, one school playground is 150 feet from a well.) No matter how vehemently citizens object, the ability to pass local ordinances regulating gas and oil producers can be superseded by state or federal regulations. This provides the industry rights normally not allowed under the law.
For example, in 38 states you can’t say no to fracking on your land if others in your area have already signed leases.
Some people we know who have leased their property worry that the companies owning their leases are simply speculating in land and will sell those leases to foreign companies. I held up my hand at one meeting and asked an industry representative if any leases might ever be sold to non-U.S. companies. “Absolutely not,” I was told. “This is about American energy independence.”
I came home and looked it up. All sorts of huge foreign companies are buying up rights. For example, the Australian company BHP Billiton bought 4.75 billion worth of shale assets in Arkansas, the French company Total will pay 2.25 billion for shale assets in Texas and 2.32 billion for assets in Ohio, and the Chinese firm, Sinopec, is spending billions to scoop up assets across the U.S. from firms like Devon and Chesapeake. Selling these assets is, of course, the prerogative of any company owning them.
On health concerns:
A local man stood up with a jug of brown water from his once clear well. Since his land was fracked the water has been foul smelling and murky, although state officials told him it was okay to drink. Another woman said brine was dumped on a road by her house and when she paid to have it tested it was found to contain chemicals associated with fracking, although state officials declined to investigate. I talked to many other people at these meetings: college students, farmers, retirees, mothers with small children living near active fracking sites. The information they shared was alarming. Here’s a little of what I’ve been able to confirm.
Each fracking operation takes 1.2 million gallons to 5 million gallons of water, sometimes more. Each additional time a site is fracked more water is required. Water stress (an imbalance between water use and water resources) is fast becoming an alarming global issue. When water is withdrawn from natural sources for drinking, irrigation, and other typical uses it normally finds its way back into the global water supply. But a substantial portion (15 to 40 percent) of the water used in fracking operations is left deep in the ground. What does come back up (called “flowback” as well as “produced water” which naturally occurs in shale) is often put in deep injection wells for long-term storage. This method not only edges up the potential for earthquakes, it also takes much-needed water out of planetary circulation.
The fluid that comes back up also contains ingredients that didn’t go in. This means naturally occurring matter such as heavy metals, volatile organic compounds (including benzene, toluene, xylene), radioactive materials (including lead, arsenic, strontium), even acidic microbes. It also means chemical compounds created by the reactions of chemicals during any stage of the process. Claims of air, ground, and water pollution due to fracking-related activity are often dismissed by industry and government officials because some contaminants are considered “naturally occurring.” And let’s not forget the water’s salinity. Fracking wastewater has two to three times more salt than sea water and more than 180 times the level considered acceptable to drink by the EPA.
Although the industry insists that all chemicals used in fracking are on the record there are still rules in place allowing them to claim chemicals are proprietary or to disclose what’s used only after the drilling has been completed. In several states including Pennsylvania and Ohio, physicians are bound by a “gag rule” which prevents doctors from sharing information about symptoms, diagnoses, and disease clusters related to fracking chemicals even with other doctors and public health officials.
There’s a great deal more—it’s well worth your time to read the whole article. What Laura’s doing in this piece is what we talk so often about wanting to teach our children to do: ask probing questions, research deeply, consider the evidence carefully, think critically.
