Job Description

SRNS is looking to hire a Groundwater Modeler for flow and fate and transport groundwater modeling. This position is within the Facilities & Systems Engineering Organization for the Environmental Compliance & Area Completion Project (EC&ACP) Group.

Responsibilities include:
• Function as subject matter expert (SME) for groundwater flow and fate and transport modeling in the EC&ACP Engineering group
• Function as a technical point of contact for our subcontracted groundwater flow and fate and transport modeling services contract
• Direct and participate in the geologic, hydrologic, and geochemical aspects of environmental characterization and remediation.
• Interpret and integrate geologic, hydrologic and geochemical data and information to develop conceptual models of complex unconsolidated hydrogeologic systems, and assess their impacts on the fate and transport of contaminants and remediation of hazardous waste sites.
• Conduct vadose zone modeling to determine potential contaminated source area impacts to groundwater.
• Conduct or oversee groundwater flow and fate and transport modeling to evaluate remedial alternatives and support remedy selection.
• Provide modeling leadership and participate in the geologic, hydrologic, and geochemical aspects of environmental characterization and remediation as a team member.
• Prepare/review groundwater modeling and effectiveness monitoring reports.
• Contribute to the preparation of work plans related to investigation and remediation activities
• Observe and provide technical input during execution of field characterization and remediation.
• Prepare and/or review technical reports
• Review historical groundwater modeling reports and supporting data and develop recommendations for additional investigation and modeling
• Work closely with geographic information system experts to develop visually compelling and informative graphics
• Work within quality/budget/schedule expectations and scope-specific assignments
• Have a safety-oriented behavior with a demonstrated commitment to safe work practices

Experience should include:
• Knowledge of the design and implementation of groundwater flow and fate and transport models (such as GMS) for simulating complex hydrogeologic systems and contaminant transport.
• Knowledge of the design and implementation of vadose zone models (such as SESOIL) for simulating source zone to groundwater impacts. complex hydrogeologic systems.
• Knowledge of hydraulic parameters affecting hazardous waste characterization and remediation under various subsurface flow regimes, and aquifer testing and analysis techniques.
• Knowledge of the geochemical characteristics of common classes of environmental contaminants (e.g., chlorinated solvents, metals, PCBs, radionuclides) and contaminant fate and transport mechanisms
• Experience with depositional environments, sedimentary facies, geomorphology, and their impacts on hydrology and aquifer characteristics.
• Experience developing hydrogeological conceptual site models
• Experience with various remediation systems (e.g., biodegradation, in situ oxidation, geochemical transformation) and how they would be modeled to evaluate future contaminant fate and transport impacts.
• Familiarity with mapping and visualization software, databases, and environmental geostatistical analyses.
• Presentation at technical conferences and publication in technical journals.
• Knowledge of environmental cleanup laws (e.g., RCRA, CERCLA) and related regulations.
• Ability to manage/work multiple projects with different customers.
• Ability to produce well written reports.
• Interpersonal and communication skills in diplomatic interactions with others, including people having a wide variety of backgrounds, and ability to work constructively as part of a team.

Define scope of technical programs and develop effective and efficient solutions to challenges which involve unique or controversial problems. Routinely use systems and meet all requirements with little supervisory guidance. Assist in teaching newer professionals and guiding their efforts.

Incorporate conventional engineering or scientific practices and a variety of complex features such as complicated technical requirements, application of new or special materials or processes and difficult coordination or oversight requirements into problem solving and program planning where only general objectives are stated.

Coordinate various phases of the activity and perform development work in assigned field.

Define specific problems based on general problem information from management and customers.

Plan technical effort and coordinate activities with those of other divisions, departments and sections in focuses areas to solve problems.

Ensure compliance with technical requirements of assigned work, proper utilization and training of personnel operating under one’s technical guidance, and compliance with approved schedules and staffing estimates.

Ensures appropriate technical performance of the end product developed and designed to resolve the original problem.

Determine scheduling and staffing requirements for assigned tasks, in collaboration with management.

Demonstrate cost and schedule consciousness through timely completion of assigned tasks and projects.

Communicate results and objectives verbally and in manuscript form to customers, colleagues and management.

Enhance expertise in field through participation in local technical societies.

Demonstrate creative ability through medium of patent disclosures, problem solving, engineering reports, technical papers and articles.
