Organic Compounds Identified via Gas Chromatography-Mass Spectrometry in Produced Water Samples Collected at the Marcellus Shale Energy and Environment Laboratory (MSEEL) 2015-2019, Morgantown Industrial Park (MIP), West Virginia

The Marcellus Shale Energy and Environmental Laboratory (MSEEL) field site in Morgantown, WV was established by West Virginia University in order to increase understanding of factors that affect resource recovery and environmental impacts from unconventional oil and gas development. The site, which is located in the Morgantown Industrial Park (MIP) adjacent to the Monongahela River, includes one well pad which hosts four horizontal gas wells that target the Marcellus Shale approximately 7400 ft below ground level. As part of the MSEEL study, the MIP 5H well was drilled in 2015. Water samples were collected from the holding pond used to hydraulically fracture the MIP 5H well (API 47-061-01699), and a time series of produced water samples were collected from the MIP 5H separator tank starting in 2016 when the well was opened for flowback and ending in 2019. This data release includes semi-quantitative analysis of polycyclic aromatic hydrocarbons (PAHs) identified in these water samples as well as a list of non-target compounds that were identified via gas chromatograph-mass spectrometry analysis and subsequent spectral matching against mass spectral libraries.
