The candidate will be part of a holistic assessment of the NASA White Sands Test Facility (WSTF) groundwater monitoring program. Responsibilities include identifying redundancies or gaps in monitoring well coverage, highlighting areas with elevated contaminant concentrations requiring more aggressive remedial action, and determining sampling schedules that balance data needs with budget constraints in support of the WSTF environmental restoration program. Activities include defining and documenting the existing monitoring program, evaluating historical data, determining appropriate qualitative and/or quantitative evaluation approaches, applying industry-standard optimization tools, developing recommendations for optimal monitoring well distribution and sampling frequency, and preparing final assessment deliverables.

Primary Role:

Serves as the technical authority for hydrogeology, fractured bedrock behavior, and development of the Conceptual Site Model (CSM).

Key Responsibilities:

• Lead evaluation of site‑specific geology, geochemistry, and groundwater flow.
• Develop and refine the CSM incorporating historical and current data.
• Apply professional judgment to interpret complex fractured‑bedrock systems.
• Identify monitoring network redundancies and data gaps.
• Guide selection of qualitative vs. quantitative evaluation approaches.

Requirements

• Advanced degree in Hydrogeology or Geological Engineering.
• Extensive fractured‑bedrock groundwater monitoring experience.
• Demonstrated experience developing regulator‑accepted CSMs at RCRA sites.

Due to the nature of the government contract requirements and/or clearances requirements, US citizenship is required.
