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.
