Toya Jones’ professional experience has focused on the areas of aquifer characterization and the development and application of numerical models for water resources, environmental restoration, hazardous and radioactive waste disposal, and regulatory compliance projects. Using the numerical codes TOUGH2, SWIFT-II, GRASP II, MODFLOW, ECLIPSE, and nSIGHTS (well-test simulator), she has modeled single- and multi-phase flow and transport, density effects on fluid flow and solute migration, and transport through porous and fractured media and has interpreted data from well and tracer tests. Her experience with water resource evaluations includes the collection and synthesis of data to develop conceptual models based on site-specific hydrogeologic information, the implementation of conceptual models into numerical models, and the assessment of groundwater and surface water vulnerability considering intrinsic properties, external threats, and consequences of contamination. She serves in key technical roles for the development of groundwater availability models where her efforts include compiling and analyzing aquifer water-level data, establishing regional groundwater flow and pre-development aquifer conditions, developing historical head surfaces, evaluating cross-formational flow, evaluating groundwater and surface water interaction, evaluating natural aquifer discharge, estimating historical pumping trends, and developing conceptual models. Toya has experience in developing and accessing transport parameters for large-scale regional groundwater transport models and assessing environmental impacts to groundwater from historical disposal of radioactive waste. In support of environmental restoration and waste isolation projects, she has developed site-specific numerical models to evaluate the fate and transport of contaminants in the subsurface. She has also applied her modeling expertise to assist in obtaining environmental permits, including conducting modeling for no-migration demonstrations for permitting of hazardous waste disposal wells and unsaturated zone flow and transport modeling to support licensing of radioactive waste disposal facilities.
