Develop and interpret thermodynamic equilibrium and kinetic-controlled reaction models using PHREEQC; collaborate with hydrology and hydrogeologic models to simulate reactive transport; design and oversee material characterization and field and laboratory testing programs; and evaluate acid rock drainage, metal leaching, mineral solubility, and water chemistry to support predictive and defensible decision-making. You will provide technical direction on conceptual site models and assessment of geochemical systems, oversee data collection and analysis, lead predictive modeling efforts, and contribute to strategic decision-making related to acid rock drainage, metal leaching, mineral solubility, and water quality.
