Closure Regulatory Scientist; Mid-Career

Job Responsibilities/Duties

Hanford Tank Waste Operations & Closure (H2C) delivers exceptional performance in safely removing, treating, and disposing of tank waste. H2C leads the nation’s largest and most complex radioactive waste cleanup, including closure of the legacy waste tanks at Hanford containing 56 million gallons of radioactive and chemical waste.

Joining H2C means becoming part of a team dedicated to creating "The Solution Today for a Better Tomorrow." At H2C, our culture is deeply rooted in our Vision, Mission, Values, and Behaviors, which guide our efforts on the Hanford Site and within our communities. Our vision to tackle the Department of Energy’s largest environmental challenge reflects our commitment to leaving a positive legacy for future generations.

We strive to deliver exceptional performance in safely removing, treating, and disposing of tank waste. Our values emphasize living safely, acting with integrity, and working collaboratively as a team. We encourage innovation, personal accountability, and continuous improvement, fostering an environment where everyone is empowered to contribute to our mission and celebrate our achievements. By embracing these principles, you will be part of a forward- thinking organization dedicated to making a meaningful impact today and for the future.

H2C Closure & Interim Measures (C&IM) performs the regulatory and technical work necessary to achieve tank farm closure. We develop the regulatory documents that support closure and corrective actions under State and Federal regulations for radioactive and hazardous waste management and interim measures that protect the environment from past tank releases. Our work includes soil and groundwater contamination assessments, vadose zone characterization, development of closure plans and RCRA field investigations (RFI)/corrective measures studies (CMS), barrier projects, and coordination with DOE and regulatory agencies.

We are expanding our team and seeking an early to mid-career Closure Regulatory Scientist to use their analytical skills to transform complex environmental characterization data into useful information that helps solve closure challenges. The selected candidate will work with and learn from their teammates as they develop algorithms, recognize data trends, and draw conclusions. They will assist in preparation of RCRA corrective action materials, environmental regulatory analyses, and closure planning documents in alignment with multi-year regulatory schedules and milestones, including those related to barrier geophysical and hydrologic monitoring, vadose zone characterization, sampling and analysis plans (SAP), data quality objectives (DQO), RFI/CMS, data quality assessments, and data usability assessments.

Candidates should enjoy and have some prior experience with technical and statistical data analysis of geologic, hydrologic, geophysical, analytical, geochemical, and/or risk-based datasets, and must be able to contribute towards data interpretation (causal analysis, trends, etc.) and capture conclusions within technical reports.

In addition, they should be able to demonstrate the following knowledge, skills and/or abilities:

• Strong analytical skills, attention to detail, and ability to translate technical findings into clear regulatory or technical reports.
• Strong proficiency in Microsoft Excel, including formulas, charting, and basic statistical tools; familiarity with other Microsoft Office applications (Word, Outlook, PowerPoint).
• Experience with data exploration, cleaning, editing, analysis, visualization, and mining; ability to interpret environmental datasets and identify trends.
• Familiarity with regulated environmental programs and documentation (RCRA, CERCLA, or state equivalents).
• Familiarity with contaminant fate and transport modeling concepts.
• Comfort preparing presentations to communicate technical concepts, project status, or recommendations.

Typical work assignments include:

• Environmental Data Evaluation – Support review and interpretation of soil, groundwater, and analytical data, including data quality and usability assessments to ensure regulatory defensibility and…
