Fracking risks to ground water assessed
Another tiny miracle: Graphene oxide soaks up radioactive waste
(Phys.org)—Graphene oxide has a remarkable ability to quickly remove radioactive material from contaminated water, researchers at Rice University and Lomonosov Moscow State University have found.
Methane levels 17 times higher in water wells near hydrofracking sites
A study by Duke University researchers has found high levels of leaked methane in well water collected near shale-gas drilling and hydrofracking sites. The scientists collected and analyzed water samples from 68 private ...
Fracking leaks may make gas 'dirtier' than coal
(PhysOrg.com) -- Extracting natural gas from the Marcellus Shale could do more to aggravate global warming than mining coal, according to a Cornell study published in the May issue of Climatic Change Letters (105:5).
New study identifies organic compounds of potential concern in fracking fluids
A new University of Colorado Boulder framework used to screen hundreds of organic chemical compounds used in hydraulic fracturing, or fracking, shows that 15 may be of concern as groundwater contaminants ...
Oklahoma earthquakes linked to oil and gas drilling, study shows
Stanford geophysicists have identified the triggering mechanism responsible for the recent spike of earthquakes in parts of Oklahoma-a crucial first step in eventually stopping them.
Earthquake activity linked to injection wells may vary by region
The Williston Basin in north central U.S. produced fewer earthquakes caused by wastewater injection than in Texas, suggesting the link between seismicity and production activities may vary by region, according ...
Fracking confirmed as cause of rare 'felt' earthquake in Ohio
A new study links the March 2014 earthquakes in Poland Township, Ohio to hydraulic fracturing that activated a previously unknown fault. The induced seismic sequence included a rare felt earthquake of magnitude ...
Electrodialysis can provide cost-effective treatment of salty water from fracked wells
The boom in oil and gas produced through hydraulic fracturing, or fracking, is seen as a boon for meeting U.S. energy needs. But one byproduct of the process is millions of gallons of water that's much saltier ...
New tracers can identify frack fluids in the environment
Scientists have developed new geochemical tracers that can identify hydraulic fracturing flowback fluids that have been spilled or released into the environment.
Hydraulic fracturing linked to earthquakes in Ohio
Hydraulic fracturing triggered a series of small earthquakes in 2013 on a previously unmapped fault in Harrison County, Ohio, according to a study published in the journal Seismological Research Letters.
Gas leaks from faulty wells linked to contamination in some groundwater
A study has pinpointed the likely source of most natural gas contamination in drinking-water wells associated with hydraulic fracturing, and it's not the source many people may have feared.
Residual hydraulic fracturing water not a risk to groundwater, study says
Hydraulic fracturing—fracking or hydrofracturing—raises many concerns about potential environmental impacts, especially water contamination. Currently, data show that the majority of water injected into ...
Groundwater is safe in potential N.Y. fracking area
Two Cornell hydrologists have completed a thorough groundwater examination of drinking water in a potential hydraulic fracturing area in New York's Southern Tier. They determined that drinking water in potable ...
