“Impacts of Unconventional Natural Gas Wastewater Disposal on Surficial Streams”
Dr. Denise Akob is visiting from the U.S. Geological Survey.
The development of unconventional natural gas resources via modern techniques like hydraulic fracturing, has increased rapidly in recent years. However, the environmental impacts and risks are not yet well understood. A single well can generate up to 5 million L of wastewater (WW), consisting of a blend of injected fracturing fluids and brine from the formation. One method for the disposal of WW is underground injection. The U.S. Geological Survey staff are assessing the potential risks of this method through an intensive, interdisciplinary study at an injection disposal facility in the Wolf Creek watershed in West Virginia. It is anticipated that these studies will provide a useful model for evaluating the potential impact of a WW disposal facility on adjoining surface- and shallow groundwater.
