“…Even when wastewater is treated, there is evidence that discharges can negatively impact downstream water quality. 41,42 This is because some facilities, particularly POTWs, are not designed to treat constituents such as chloride that can be found in wastewater at high concentrations. Important statistical evidence for regional impacts related to treated discharge was provided by Olmstead et al 6 who determined that, in the Marcellus, discharge from POTWs accepting gas eld wastewater led to downstream increases in chloride concentrations in 2011, at least on a seasonal basis.…”

“…In NY, the USGS has compiled regional surface water quality data and has noted past monitoring efforts in which active oil and gas development, as well as road salt and urban sewage effluents have been shown to increase specic conductance. 42 For now, monitoring efforts remain a challenge because of the dispersed nature of shale gas drilling, and because of technical limitations in collecting realtime information on anything other than basic water quality parameters. Still, rigorous monitoring is capable of providing insight on regional water quality trends over time, and may help to indicate when more detailed water quality sampling and investigation is warranted.…”

Unconventional shale gas development promises to significantly alter energy portfolios and economies around the world. It also poses a variety of environmental risks, particularly with respect to the management of water resources. We review current scientific understanding of risks associated with the following: water withdrawals for hydraulic fracturing; wastewater treatment, discharge and disposal; methane and fluid migration in the subsurface; and spills and erosion at the surface. Some of these risks are relatively unique to shale gas development, while others are variations of risks that we already face from a variety of industries and activities. All of these risks depend largely on the pace and scale of development that occurs within a particular region. We focus on the United States, where the shale gas boom has been on-going for several years, paying particular attention to the Marcellus Shale, where a majority of peer-reviewed study has taken place. Governments, regulatory agencies, industry, and other stakeholders are challenged with responding to these risks, and we discuss policies and practices that have been adopted or considered by these various groups. Adaptive Management, a structured framework for addressing complex environmental issues, is discussed as a way to reduce polarization of important discussions on risk, and to more formally engage science in policy-making, along with other economic, social and value considerations. Data suggests that some risks can be substantially reduced through policy and best practice, but also that significant uncertainty persists regarding other risks. We suggest that monitoring and data collection related to water resource risks be established as part of planning for shale gas development before activity begins, and that resources are allocated to provide for appropriate oversight at various levels of governance.
