Fleets of trucks have to make hundreds of trips to carry the fracking fluid to and from each well site.

«By measuring naturally occurring ammonium and iodide in numerous samples from different geological formations in the Appalachian Basin, including flowback waters from shale gas wells in the Marcellus and Fayetteville shale formations, we show that fracking fluids are not much different from conventional oil and gas wastes,» said Jennifer S. Harkness, lead author of the study and a PhD student at Duke's Nicholas School of the Environment.

In 2011, in response to growing public concern about the possible environmental and human health effects of fracking wastewater, Pennsylvania's Department of Environmental Protection requested that the discharge of fracking fluids and other unconventional oil and gas wastewater into surface waters be prohibited from central water - treatment facilities that release high salinity effluents.

«It's not only fracking fluids that pose a risk; produced water from conventional, or non-fracked, oil and gas wells also contains high levels of radium, which is a radioactive element.

In the 121 - page draft report released today, EPA officials said that the contamination near the town of Pavillion, Wyo., had most likely seeped up from gas wells and contained at least 10 compounds known to be used in frack fluids.

The upshot is a growing — albeit incomplete — list of preferred chemicals that companies such as Apache can choose from as they design their fracking fluids.

Fluid injection can occur with conventional oil and gas extraction methods, which extract fuel from underground pools, and with unconventional methods like fracking, which recover oil and gas from small voids in rocks.

It can then be sucked back out as the natural gas is extracted from the reservoir, meaning that there is a virtually complete recovery of the fracking fluid; water - based methods have roughly a 50 percent recovery rate.

Fracking has already drawn considerable scrutiny from environmental groups, unhappy homeowners, and teams of lawyers who blame the drilling method for polluting pristine rivers, turning bucolic farmlands into noisy industrial zones, and leaking enough methane to make ordinary tap water as flammable as lighter fluid.

A bill now under consideration on Capitol Hill would grant the EPA oversight of fracking and force drilling companies, which are currently exempt from portions of the Clean Water Act, to disclose the chemicals they use in fracturing fluids.

The risk of human - made earthquakes due to fracking is greatly reduced if high - pressure fluid injection used to crack underground rocks is 895m away from faults in the Earth's crust, according to new research.

They looked both at wells used for enhanced oil recovery — in which fluid is injected to flush lingering oil from a depleted reservoir — and at those used to dispose of wastewater from conventional oil and gas extraction or from hydraulic fracturing (fracking).

Their discovery could aid secure fracking — in which rocks below ground are split with high - pressure fluids — or extraction of methane gas from deep coal beds.

The report explains that along with natural gas, production wells in the Azle area of the NEGF can also bring to the surface significant volumes of water from the highly permeable Ellenburger Formation — both naturally occurring brine as well as fluids that were introduced during the fracking process.

And that is an underestimate of the amount of brine, fracking fluid and other contaminated water that flows back up a well along with the natural gas or oil, because it is based on incomplete data from state governments gathered in 2007.

But they also found that produced water contained potentially toxic chlorocarbons and organobromides, probably formed from interactions between high levels of bacteria in the water and salts or chemical treatments used in fracking fluids.

My concern is that many will read the title, «Geochemical evidence for possible natural migration of Marcellus Formation brine to shallow aquifers in Pennsylvania,» and immediately infer that residual treatment water (i.e., frack fluid) is most likely to leak into groundwater from depths of several thousand feet.

The study found no evidence of contamination from chemical - laden fracking fluids, which are injected into gas wells to help break up shale deposits, or from «produced water,» wastewater that is extracted back out of the wells after the shale has been fractured....

Another prime concern is water contamination either from poorly constructed wells or mismanagement of water and other fluids used during hydraulic fracturing, or fracking, of wells to liberate gas from the shale.

It's from instances where waste fluids — for example, the water used in fracking — are injected deep into the earth.

The problem is that treating oil and gas waste from fracked wells remains particularly tricky because the industry is still allowed to keep secret information about which chemicals drillers use when injecting fluids to crack open shale formations to release oil and gas.

«Drilling companies have won exemption from just about every piece of federal environmental law except the requirement to get permits if they use diesel in their fracking fluid,» said Dusty Horwitt of the Environmental Working Group.

The Duke study found no evidence of contamination from chemicals in the fracking fluids that are injected into gas wells to help break up shale deposits, or from produced water.

The report concludes that while there have been surface spills of fracking wastewater, there is no evidence of groundwater contamination from fluids injected thousands of feet below the surface.

The compromise on the chemical concentrations was that the chemicals and concentrations would be listed separately from the descriptions of the products in the frack fluid.

A separate study at Cornell University recently identified yet another mechanism increasing the risk of carrying contaminants from the path of the fracking fluids into clean groundwater reservoirs: the same properties that make the fluids effective at fracking help fracking fluids dissolve contaminants like heavy metals that up until now have clung safely to soils in the form of colloids.
