Geochemical Investigation Of Tungsten In Two Groundwater Flow Systems: The Carrizo Sand Aquifer, Texas, USA, And The Aquia Aquifer, Maryland, USA
Dave, Heeral B (Environmental & Earth Science, 2008-08-08)Groundwater sampled were collected from well sites located within the Carrizo Sand aquifer in Atascosa and McMullen counties in Texas, and also within the Aquia Aquifer, Maryland in the counties of Queen Anne's, Kent, and ... -
Hydrogeochemical Evolution Of Arsenic Along Groundwater Flow Paths: Linking Aqueous And Solid Phase Arsenic Speciation
Haque, Shama (Environmental & Earth Science, 2007-08-23)The central hypothesis of this Doctoral research work is that changes occurring along groundwater flow paths that accompany chemical weathering and oxidation-reduction reactions catalyze both arsenic (As) mobilization from, ... -
Selenium Speciation Along A Groundwater Flow Path In The Carrizo Aquifer, Southeastern Texas, USA
Basu, Rituparna (Geology, 2007-08-23)Selenium concentration and speciation [Se (VI), Se (IV) and Se (-II)] was determined along a flow path in the Carrizo Sand aquifer (southeastern Texas). Groundwater sampling was carried out in March 2006, from ten wells ... -
Trace Element Geochemistry In Groundwater Flow Systems
Willis, Stephanie Scholten (Environmental & Earth Science, 2011-03-03)This research focuses on trace element geochemistry in three groundwater flow systems: the Carrizo Sand, the Upper Floridan, and the Aquia aquifers. The focus is threefold: (i) studying the geochemical behavior, concentrations, ...
