     "text": "This current study supports the previous work done by the USGS and shows that organic substances consistent with a source from wastewater originating from UOG production were observed in stream water and sediments at sites immediately downstream from the facility.  Concentrations of organics were low and included compounds like 2-(2-butoxyethoxy)-ethanol; tris(1-chloro-2-propyl)phosphate; \u03b1, \u03b1-dimethyl-benzenemethanol; 3-ethyl-4-methyl-1H-pyrrole-2,5-dione; and tetrahydro-thiophene-1,1-dioxide, which are all present in wastewater from UOG production. Toxicological assays of human cell line exposures to water and sediment from the creek showed minimal effects. Low-level organic contamination seems to be limited to the part of the creek immediately downstream from the facility. Organic contaminants were not evident farther downstream on Wolf Creek to the point where the tributary waters enter the New River, which are both used for drinking water and recreational purposes."

     "text": "Previous U.S. Geological Survey (USGS) studies determined the presence of inorganic contaminants related to UOG production in a small intermittent tributary to Wolf Creek that runs through a wastewater injection and disposal facility in West Virginia. In this current study, the organic chemical composition (nonpurgeable dissolved organic carbon, extractable hydrocarbons, C1\u2013C6 hydrocarbons, biocides, and disinfection byproducts) and cell line toxicity were assessed in stream water and sediment samples collected upstream from, within, and downstream from the disposal facility, and at a background site in a separate drainage basin."

     "text": "The disposal of large volumes of wastewater is an issue facing the unconventional oil and gas (UOG) production industry. Significant progress has been made in recycling water used in hydraulic fracturing and reducing the amount of wastewater generated.  Most of the remaining wastewater is disposed of by deep underground injection because the wastewater is unsuitable for disposal in standard wastewater treatment plants. The risks due to leaks, spills, and migration of these fluids into natural waters are unknown."
