CHROTRAN is a massively parallel numerical simulator for in situ biogeochemical remediation of heavy metals in heterogeneous aquifers

CHROTRAN can simulate sophisticated, multi-scale biogeochemical remediation processes:

  • Groundwater remediation of heavy metals and other contaminants
  • Bioremediation and chemical remediation
  • Multi-dimensional processes from the laboratory to field scale
  • Physical and chemical heterogeneity
  • Field pilot studies and long-term deployments

CHROTRAN is based upon the existing PFLOTRAN code framework, utilizing:

  • Fully coupled subsurface flow and reactive transport
  • Highly parallelized computational solvers
  • Large number of unknown variables
  • Complex model domains and highly refined computational grids
  • Existing chemistry capabilites (mineral precipitation/dissolution, aqueous complexation)

CHROTRAN can be coupled to MADS (Model Analysis & Decision Support) for:

  • Model inversion and calibration
  • Sensitivity analysis
  • Uncertainty quantification
  • Decision analysis and support

CHROTRAN has been developed to address groundwater remediation at the LANL (Los Alamos National Laboratory, NM) legacy waste sites and contaminated areas.
