Innovative Methods for Solving Multicomponent Biogeochemical Groundwater Transport on Supercomputers
To evaluate the performance of the Jacobian-Free Newton-Krylov method, PARTRAN was used to simulate enhanced in situ bioremediation of subsurface NAPL (non-aqueous phase liquid) contamination on the ASCI Q supercomputer at Los Alamos National Laboratory, on which a study of parallel …

Groundwater transport of Escherichia coli bacteria to open surface waters on Virginia's Coastal Plain: a GIS approach
… septic tanks. Septic tank effluent (STE) may be transported through the soil and contaminate the groundwater. Submarine groundwater discharge (SGWD) may then be providing a conduit into the estuary for the bacteria. Data of OSWDS locations was not available, thus the groundwater transport …

Modeling the biodegradation kinetics of dissolved organic contaminants in a heterogeneous two-dimensional aquifer
… of this dissertation was to develop a versatile groundwater transport model capable of incorporating various types of biodegradation kinetic sub-models, and to use the model to examine the interaction between transport and biodegradation processes in a two-dimensional heterogeneous aquifer. …

Uranium isotopes as indicators of uranium immobilization and remobilization in contaminated aquifer settings
… using U concentrations alone is challenging, as groundwater transport, aquifer heterogeneity, and U(VI) adsorption can complicate data interpretation. U isotopes (238U/235U) provide a more direct indicator of these geochemical reactions controlling U mobility. U(VI) reduction induces a strong …

Phytoplankton community structure response to groundwater-borne nutrients in the Inland Bays, DE
… experiments to determine the impacts of groundwater-borne nutrients on biomass and response in community structure of phytoplankton. To assess the impacts of groundwater-borne nutrients, we measured chlorophyll a concentrations as a proxy for overall biomass and used genetic sequencing …

Modeling multiphysics of traveling wave reactor spent fuel disposal in deep crystalline host rock
… one million years. Other than human intrusion, groundwater transport is the only important mechanism for escape of radioactive material from the repository. Heat decay, combined with the natural geothermal flux, causes groundwater to flow, compromising radioactive containment. The numerical …

Groundwater Interactive: Interdisciplinary Web-Based Software Incorporating New Learning Methodologies and Technologies
Groundwater related courses are offered through several colleges at Virginia Tech. These classes enroll a diverse group of students with varied academic backgrounds and educational levels. Though these classes emphasize different aspects of groundwater resources, they lack a unified approach in …
