Following a shallow M5.8 earthquake on Saturday, September 3, 2016, Oklahoma authorities have shut down 37 wastewater wells used by the fracking industry to extract oil and gas. According to Oklahoma Governor Mary Fallin, the decision to shut down the wells was a…
A strong and shallow earthquake registered by the USGS as Mw5.8 hit 15 km (9.3 miles) northwest of Pawnee, north-central Oklahoma at 12:02 UTC on September 3, 2016. The agency reported a depth of 5.4 km (3.3 miles). Between September 1 and 3, USGS registered a total…
A new study has been conducted to investigate the toxic barium metal in fracking wastewater. Although the chemicals inserted into injected freshwater during the mixing process with highly saline brine in the rock are generally assumed to be partially responsible for…
Over the past ten years in the United States, unconventional gas and oil drilling using hydraulic fracturing, or fracking, has experienced a meteoric increase. Since well drilling requires an influx of water, materials and workers into yotherwise rural and remote
A dramatic increase in the rate of earthquakes in the central and eastern US since 2009 is associated with fluid injection wells used in oil and gas development, says a new study by the University of Colorado Boulder and the USGS.The number of earthquakes associated wit
Johns Hopkins Bloomberg School of Public Health researchers say that levels of radon in Pennsylvania homes – where 42 percent of readings surpass what the U.S. government considers safe – have been on the rise since 2004, around the time that the fracking in
Two new U.S. Geological Survey publications that highlight historical hydraulic fracturing trends and data from 1947 to 2010 are now available.Hydraulic fracturing is presently the primary stimulation technique for oil and gas production in unconventional resource reser
It seems as though, with each day that passes, yet another health and environmental hazard is identified as being linked to hydraulic fracking, the process of injecting more than 200 chemicals at high pressure into the ground, shattering rock and releasing one America&#
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 (SRL) on October 14, 2014. Nearly 400 small earthquakes occurred be
