Geology Environmental Geology Geochemistry Hydrologic Sciences Water Resource Management Petroleum Production Groundwater Contamination Marcellus Pennsylvania Water Wells Hydraulic Fracturing Rural Ground Water Pollution Flowback Using graphical and statistical methods, geochemical data from 21 allegedly contaminated ground water wells in northeastern Pennsylvania were compared with data from historical ground water, Marcellus flow-back fluid, and other contaminated waters. The graphical methods included box and whisker plots, Piper diagrams, Stiff diagrams, and Cl/Br vs. Cl cross-plots. The statistical methods included summary statistics, analysis of variance, and discriminant analysis. The geochemical data collected for this study included the following major ions, trace metals, nutrients, and physical properties: sodium (Na), potassium (K), calcium (Ca), magnesium (Mg), barium (Ba), strontium (Sr), manganese (Mn), iron (Fe), aluminum (Al), chloride (Cl), bromide (Br), sulfate (SO4), arsenic (As), nitrate-nitrite as N, total Kjeldahl nitrogen, total nitrogen, alkalinity, and total dissolved solids (TDS).The graphical and statistical results show that none of the 2012-2013 ground water wells were detectably impacted by flow-back fluids. Instead, the results show that at least one well is contaminated with animal waste or septic effluent. Discriminant analysis of the 2012-2013 ground water samples supports this observation. The remaining wells are geochemically similar to historical ground water wells both graphically and statistically. These findings suggest that the major and trace element geochemistry of northeastern Pennsylvania ground water has not been detectably influenced by flow-back fluid spills at these 21 sites. 2014-04-24 English text Kent State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=kent1397949957 http://rave.ohiolink.edu/etdc/view?acc_num=kent1397949957 unrestricted This thesis or dissertation is protected by copyright: some rights reserved.
