Sentences with phrase «processing fracking wastewater»

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.

Not exact matches

Since then, we have all learned a lot about the risks of fracking — about how the toxic chemicals used can migrate into drinking water, about how methane can leak out of well casements, about the danger of disposing of billions of gallons of polluted wastewater the process produces.

Many of the EPA's comments focus on how the state DEC will handle the chemically tainted wastewater from the drilling process known as hydraulic fracturing, or fracking.

In most cases, it is not hydraulic fracturing (or fracking) of oil - and gas - bearing rock that sets off tremors but the related process of wastewater injection.

Large volumes of wastewater are produced in the process of fracking.

A study published today in Science explains how wastewater injection sites — areas where toxic water left over from oil drilling and fracking processes is injected into the ground between impermeable layers of rocks to avoid polluting freshwater — could be driving the sharp increase in the sometimes - disastrous earthquake events.

Past research has shown that processes such as wastewater injection at oil drilling and fracking sites throughout the state could induce a small number of earthquakes but scientists have never been able to specifically link some of the more distant or stronger earthquakes with these sometimes faraway wastewater wells.

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.

Although fracking in the U.S. produces more than 100 billion gallons of wastewater per year, the process requires significantly less water per unit of energy than extraction and processing for coal and nuclear power, according to past research by Jackson and his colleagues.

Instead, the increased risk for seismicity is more strongly linked with the subsequent injection of the wastewater from fracking and other oil - extraction processes into massive disposal wells that are thousands of feet underground.

Drinking water contaminated by fracking wastewater can affect a person's normal respiratory, sensory and neurological processes as well as other biological functions.
