Stephen Richardson to present at the NGWA Unconventional Oil and Gas Development Conference

Stephen will present a talk “Recommended Practices for Baseline Sampling of Water Wells in Areas of Shale Gas Development” at the upcoming NGWA Groundwater Quality and Unconventional Oil and Gas Development: Current Understanding and Science Needs conference in Columbus, OH on April 25, 2017.

Baseline sampling of residential water wells is standard practice for operators in many areas of shale oil and gas development. Data collected from these sampling programs is critical for evaluating whether reported changes in local water quality are related to nearby drilling activities, or potentially naturally occurring. However, little guidance is available to operators, regulators, and contractors to support the development of sampling programs and interpretation of data. This study, funded by the Department of Energy, evaluated key sources of variability in baseline sampling results from water wells in Northeastern Pennsylvania. Results culminated in the development of recommended practices and guidance for dissolved gas sampling methods, well purging practices, and expectations for temporal variations in methane concentrations and methane-geochemical parameter relationships.
