Sentences with phrase «fracking fluid into»

The 600 - plus - page report that resulted looks at a variety of ways fracking could have an effect on local drinking water: withdrawing millions of gallons of water needed to frack a well, improperly mixing chemicals with the water at the well, injecting that fracking fluid into the ground at high pressure to fracture rock as much as two miles beneath the surface, handling the contaminated water then produced by the well and finally improperly storing or disposing of that water.

Moreover, scientists suspect that the injection of used fracking fluid into deep disposal wells may have triggered dozens of recent small earthquakes in northeastern Ohio and north Texas.

California officials have ordered an emergency shut - down of 11 oil waste injection sites and a review of over 100 others in the Central Valley for fear that companies may have been pumping fracking fluids into drinking water aquifers.

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.

Not exact matches

If they survive, then it will be a good demonstration that fracking is unlikely to harm New Yorkers, even if some of the fracking «fluid» seeps into our underground aquifers.

As the toxic fracking fluids migrate into the local water table, it will add some extra pizazz -LRB-!)

Improperly drilled wells or faulty well casings can leak fracking fluids and methane gas into nearby aquifers and water wells.

That surge has coincided in time and place with the boom in unconventional oil and gas extraction such as hydraulic fracturing, or «fracking,» in which high - pressure fluid is injected into the ground to break up the underlying rock and release trapped gas or oil.

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.

But Clarens says fracking fluids could theoretically leak into aquifers, because the wells must be dug through shallow layers where the aquifers lie in order to reach shales.

California officials have ordered an emergency shut - down of 11 oil and gas waste injection sites and a review more than 100 others in the state's drought - wracked Central Valley out of fear that companies may have been pumping fracking fluids and other toxic waste into drinking water aquifers there.

Investigations by The New York Times last winter revealed that sewage - treatment plants processing fracking wastewater are discharging radioactive fluid into public waterways, in some cases upstream of intake sites for drinking water.

But according to a panel of geologists at the AAAS Annual Meeting, the culprit isn't hydraulic fracturing, or «fracking,» in which geologists crack open subsurface rocks to extract oil and gas; instead, it's the processes associated with pumping wastewater and other fluids back into the ground.

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.

Fracking — or hydraulic fracturing — is a process in which rocks are deliberately fractured to release oil or gas by injecting highly pressurised fluid into a borehole.

Typically, fracking involves injections into impermeable rock layers that inhibit the spread of fluid and increase pore pressure.

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....

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

Then a mixture, commonly known as fracking fluid, of water (90 percent), sand (9.5 percent) and chemicals (0.5 percent) is pumped into the well under high pressure to create micro-fractures in the shale and free the natural gas or oil.

During offshore fracking, a significant amount of fracking fluid returns to the surface and is either discharged into the ocean or transported for onshore ground injection.

«What's even more inexcusable is that some fracking fluids were discharged directly into the ocean without any scientific understanding of how these chemicals impact ocean ecosystems,» said Sekich.

Fracking opened up vast swaths of once - quiet forest and farmland to the constant grinding of truck traffic heading to drilling rigs that operate all day and night, poisoning the air with diesel fumes and sometimes spilling toxic drilling fluids onto fields and into streams.

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.

Even the Obama - era Environmental Protection Agency, which harbored little affection for the energy industry, concluded that fracking is «unlikely to generate sufficient pressure to drive fluids into shallow drinking water zones.»

But the idea stressed by fracking critics that deep - injected fluids will migrate into groundwater is mostly false.

In any case, after the frack fluid is captured, the well is capped with a group of pipes and valves, commonly known as a «Christmas tree,» that direct the gas into into the pipeline and processing system.

Did fracking fluids ever contain industrial waste mixtures which, if pumped into the ground for non-gas production purposes, would have been regulated as hazardous waste?

During the fracking process, millions of gallons of fracking fluid — a mixture of water, sand and toxic chemicals — are injected into the ground to break up the shale and release natural gas.

But fracking, which involves the high - pressure injection of water or a fluid mixture into a borehole to create cracks in deep - rock formations through which gas or petroleum can flow, is inherently dangerous.
