Hydrogeologist 4

About the role

You will provide expert guidance on groundwater and vadose zone conditions that directly inform cleanup and regulatory decisions for the Hanford Tank Farms. You'll analyze subsurface data, evaluate contaminant fate and transport modeling, and advise on remediation strategies that protect human health and the environment. You will also serve as the program's technical authority on leak evaluations, groundwater impacts, and the scientific foundation behind cleanup actions.

This position offers the opportunity to work on some of the most complex hydrogeologic challenges in the country, with direct influence on long-term environmental outcomes. You'll engage in technical reviews, collaborate with federal partners, shape cleanup plans, and support milestone negotiations. This role also allows you to deepen your expertise in large-scale remediation and regulatory oversight while serving as a trusted technical resource and contributing to meaningful, technically complex work that will have a lasting impact on the environment and public health.

Responsibilities

• Evaluate U.S. Department of Energy and contractor determinations of past and present single-shell tank (SST) leaks.
• Review Resource Conservation and Recovery Act (RCRA) facility investigations, scientific studies, remediation plans, sampling plans and data, and other compliance documents related to groundwater, vadose zone, and surface water contamination and cleanup at the Hanford Site.
• Develop hydrogeologic recommendations for project managers, the senior groundwater specialist, other site-wide specialists, and section managers.
• Evaluate permit requests for groundwater wells and groundwater monitoring. Review engineering reports and annual RCRA and Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) site-wide groundwater reports.
• Work collaboratively with chemists, engineers, toxicologists, and regulatory specialists to support environmental remediation that protects human health and the environment.
• Review and interpret vadose zone and groundwater fate-and-transport modeling to inform cleanup and closure planning for the SST farms.
• Plan, organize, and lead regulatory aspects of hydrogeologic investigations of subsurface conditions.
