What is the difference between Full Time Groundwater Modeling vs Hydrologist?

AspectFull Time Groundwater ModelingHydrologist
Required CredentialsBachelor's or Master's in Hydrogeology, Geology, or Environmental Science; proficiency in modeling softwareBachelor's or Master's in Hydrology, Geology, or Environmental Science; strong analytical skills
Work EnvironmentEnvironmental consulting firms, government agencies, research institutionsResearch institutions, government agencies, environmental consulting
Industry UsageDesigning groundwater models, analyzing aquifer systems, water resource managementStudying water cycles, assessing water availability, environmental impact assessments

Full Time Groundwater Modeling focuses on creating and analyzing models of groundwater systems, often requiring specialized software skills. Hydrologists have a broader scope, studying water movement and availability. While both roles work in environmental and water resource sectors, groundwater modelers specialize in simulation and data analysis, whereas hydrologists focus on field studies and water cycle processes.

Job description

Navarro Research and Engineering is recruiting a Groundwater Modeler (3953) in Las Vegas, NV.
Navarro Research & Engineering is an award-winning federal contractor dedicated to partnering with clients to advance clean energy and deliver effective solutions for complex challenges in the nuclear and environmental fields. Joining Navarro means being a part of an exceptional team committed to quality and safety while also looking for innovative strategies to create value for the client's success. Headquartered in Oak Ridge, Tennessee, Navarro has active programs in place across the nation for DOE/NNSA, NASA, and the Department of Defense.
Position Summary
Navarro is seeking a Groundwater Modeler with EarthVision experience to support groundwater modeling activities for the Nevada National Security Site (NNSS). This full-time, long-term position will be based in Navarro's Las Vegas, Nevada office and will support technical modeling, data evaluation, and visualization efforts associated with groundwater systems at NNSS.
The Groundwater Modeler will develop and apply MODFLOW-based groundwater models, integrate hydrogeologic and geologic datasets, and support technical analyses used to evaluate groundwater flow conditions, radionuclide contaminant transport, model performance, and site-specific environmental decision-making. The role requires strong technical judgment, attention to quality, and the ability to communicate modeling assumptions, methods, and results clearly to technical and project stakeholders.
Responsibilities
  • Develop, maintain, calibrate, and document groundwater flow and contaminant transport models for NNSS using the MODFLOW suite of tools.
  • Use EarthVision to develop, visualize, and interpret geologic and hydrogeologic data, including stratigraphic surfaces, model layers, and conceptual site model elements.
  • Compile, review, and evaluate groundwater, geologic, hydrologic, hydraulic, contaminant concentration, and site characterization data to support model development, calibration, and refinement.
  • Prepare model input files, boundary conditions, hydraulic parameters, stress packages, calibration targets, model outputs, and supporting technical documentation.
  • Evaluate model results, perform sensitivity checks, assess uncertainty, and support interpretation of groundwater flow conditions and site-specific hydrogeologic behavior.
  • Generate maps, figures, cross sections, tables, model visualizations, and technical summaries to support project deliverables and client communications.
  • Coordinate with hydrogeologists, geologists, engineers, environmental scientists, project managers, and client representatives to align modeling activities with project objectives, schedules, and quality requirements.
  • Apply appropriate quality assurance, configuration control, data management, and technical review practices for modeling files, datasets, calculations, and deliverables.
  • Support technical reports, presentations, work planning, and project meetings related to groundwater modeling and environmental support activities at NNSS.

Requirements
  • Bachelor's degree in hydrogeology, geology, hydrology, geoscience, environmental science, civil engineering, environmental engineering, or a closely related technical discipline.
  • Demonstrated experience developing or supporting groundwater models using MODFLOW.
  • Demonstrated experience with model optimization tools (such as PEST) and Monte Carlo (or equivalent) uncertainty approaches.
  • Demonstrated experience using EarthVision for geologic or hydrogeologic model development, visualization, and interpretation.
  • Working knowledge of groundwater flow principles, stratigraphy, hydrogeologic conceptual site models, model calibration, sensitivity evaluation, and technical documentation.
  • Ability to evaluate and integrate large technical datasets, including water-level data, hydraulic properties, geologic units, pumping or recharge information, and other model-supporting data.
  • Ability to prepare clear technical deliverables, communicate modeling assumptions and results, and work effectively with multidisciplinary technical teams.
  • Strong attention to detail, data quality, documentation, file organization, and technical accuracy.
  • Ability to work from Navarro's Las Vegas, Nevada office and support groundwater modeling activities for NNSS.

Preferred Qualifications
  • Experience supporting DOE, NNSA, NNSS, national laboratory, federal environmental, or nuclear site projects.
  • Advanced degree in hydrogeology, geology, hydrology, geoscience, environmental science, civil engineering, environmental engineering, or a closely related discipline.
  • Experience with MODFLOW-related tools or companion applications such as ModelMuse, Groundwater Vistas, MODPATH, MT3DMS, RT3D, PEST, or similar groundwater modeling software.
  • Experience with GIS, database tools, scientific visualization tools, Python, R, or other technical analysis tools used to process and evaluate hydrogeologic data.
  • Experience preparing groundwater modeling reports, model documentation packages, technical memoranda, and client-ready figures or presentations.
  • Familiarity with arid-region hydrogeology, basin-fill aquifers, fractured-rock systems, contaminant transport concepts, or complex federal site groundwater investigations.

Education and Experience
  • Bachelor's degree in hydrogeology, geology, hydrology, geoscience, environmental science, civil engineering, environmental engineering, or a closely related technical discipline is required. Relevant experience in groundwater modeling using MODFLOW and experience using EarthVision for geologic or hydrogeologic model development are required. An equivalent combination of education, technical training, and directly related experience may be considered.
  • Due to the nature of the government contract requirements and/or clearances requirements, US citizenship is required.
