• Groundwater Flow Models (MODFLOW, MODFLOW OWHM, MODFLOW Surfact, MODFLOW USG, MODFLOW 6)
• Groundwater Quality Fate and Transport Models (MT3DMS, BIOSCREEN, AT123D, BIOCHLOR)
• Unsaturated Zone Modeling (HYDRUS-1D, VLEACH, VSD2DT, SESOIL, SUTRA, TOUGH2)
• Parameter Estimation (PEST)
• Stochastic Analysis
• Uncertainty Analysis
• Geochemical Modeling (PHREEQC, MINTEQ)
