This position is in the Hydrogeology Division of the Environmental Restoration Department.

This position will be filled at either level based on knowledge and related experience as assessed by the hiring team. Additional job responsibilities (outlined below) will be assigned if hired at the higher level.

In this role you will 

  • Responsible for monitoring the performance of LLNL’s remediation wellfield and status of the groundwater and soil vapor treatment facilities. Provide ongoing status reports to the project team.
  • Analyze data to provide summaries of remediation wellfield operational history and progress of subsurface remediation for quarterly and annual regulatory reports. Provide recommendations and solutions to improve performance.
  • Analyze and interpret geologic, borehole geophysical, and hydraulic/pneumatic data, and soil, rock, water and vapor chemistry data, and provide recommendations to senior scientists.
  • Assist in the preparation of documents and presentations to Federal and State regulators, and the local community.
  • Assist in the development of hydraulic/pneumatic tests, field experiments, sampling plans; analyze results and provide interpretations to senior scientists.
  • Ensure compliance with all federal, state, and Laboratory’s environmental policies.
  • Perform other duties as assigned.

Additional job responsibilities, at the TSS.3 level
