The Peña Blanca Natural Analog Site (Mexico) is a natural analog to the U.S. Nuclear Regulatory Commission's proposed high-level nuclear waste repository at Yucca Mountain, Nevada. Here SwRI performed reactive transport studies through field and laboratory investigations and computer modeling.

Geochemistry services technical strengths at Southwest Research Institute (SwRI) include:

  • Experimental and modeling studies of ion exchange and sorption processes
  • Prediction of thermodynamic properties of high ionic strength mixed electrolyte solutions
  • Fate and transport of technologically enhanced naturally occurring radioactive materials (TENORM) (technical flyer)
  • Determination of zeolite solubilities, sorption and cation exchange properties, and surfactant modification response
  • Reaction pathway and reactive transport modeling of gas water rock systems
  • Measurements of mineral solubilities and thermodynamic properties
  • Implementation of NEPA (National Environmental Policy Act) process:
    • Provide environmental impact assessment
    • Review and preparation of environmental impact statements, environmental assessments, and categorical exclusions
