Geochemical and isotopic evidence for upward flow of saline fluid to the Mississippi River Valley alluvial aquifer, southeastern Arkansas, USA

“…Vertical upward migration of groundwater is known to affect water quality in near-surface aquifers. The conditions leading to upward migration vary, but most commonly stem from flow along preferential pathways from underlying rock units at elevated pore pressure (Carrillo-Rivera et al 1996;Mehta et al 2000;Frumkin and Gvirtzman 2006;Petitta et al 2011), thermohaline convection (Evans et al 1991;Magri et al 2009), groundwater pumping in shallow aquifers (Howard and Mullings 1996;Cherry 2019), or cross-formational or up-dip flow (Ma et al 2005). Changes in water chemistry due to upward groundwater flow or release of solutes due to dilation may also occur along faults during earthquakes (Favara et al 2001;Claesson et al 2004;Malakootian and Nouri 2010;Woith et al 2013;Skelton et al 2014;Rosen et al 2018).…”
