Emergency Management. These are the first published studies to demonstrate water-quality impacts to a surface stream due to activities Wolfcreek WV dating personals an unconventional oil and gas wastewater deep well injection disposal site. Evidence indicating the presence of wastewaters from unconventional oil and gas production was found in surface waters and sediments near an underground injection well near Fayetteville, West Virginia, according to two recent studies by the U.
The studies did not assess how the wastewaters were able Wolfcreek WV dating personals migrate from the disposal site to the surface stream. The unconventional oil and gas wastewater that was injected in the site came from coalbed methane and shale gas wells.
The scientists collected water and sediment samples upstream and downstream from the disposal site. These samples were analyzed for a series of chemical markers that are known to be associated with unconventional oil and gas wastewater. In addition, in a just-published collaborative study tests known as bioassays were done to determine the potential for the impacted surface Insatiable and unsatisfied to cause Wilfcreek disruption.
Wolfcreek WV dating personals and sediments collected downstream from the disposal facility were elevated in constituents that are known markers of UOG wastewater, including sodium, chloride, strontium, lithium and radium, providing indications of wastewater-associated impacts in the stream.
Scientists analyzed the microbial communities in sediments downstream. Production of unconventional oil and gas resources yields large volumes of wastewater, which are commonly disposed of using underground injection.
In fact, more than 36, of these disposal wells are currently in operation across the United States, according to the U.
Environmental Protection Agency, and the volume of unconventional oil and gas wastewater requiring disposal has continued to grow Wolfcreek WV dating personals a slowing in drilling and production.
The studies were published in Environmental Science and Wolfcreek WV dating personals and Daging of the Total Environment and can be found here.
They are titled:. This study is part of USGS research into the possible risks to water quality and environmental health posed by waste materials from unconventional oil and gas development.
