Toya Jones is a hydrogeologist with specialized experience in the areas of aquifer characterization and the development and application of numerical models to 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 as well as 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 consequence of contamination.  In support of environmental restoration projects, Ms. Jones has developed site-specific numerical models to evaluate the fate and transport of contaminants in the subsurface.  Representative examples of this experience include analyzing the effects of sorption and biodegradation on the migration of chlorinated benzene plumes, determining the radiation dose from operations of a mixed-oxide fabrication facility, modeling nitrate migration from disposal ponds, and developing transport parameters (i.e., effective porosity and dispersivity) for modeling the migration of contaminants resulting from underground nuclear tests.  She has 22 years of experience in conducting characterization and modeling associated with the geologic disposal of radioactive wastes.  Ms. Jones has also applied her modeling expertise to assist in obtaining environmental permits.  This includes conducting modeling for no-migration demonstrations for permitting of hazardous waste disposal wells and unsaturated zone flow and transport modeling to support a license application for a commercial low-level radioactive waste disposal facility.
