CHROTRAN

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.
