BIOCHLOR, Natural Attenuation Decision Support System
BIOCHLOR is a screening model that simulates remediation by natural attenuation of dissolved solvents at chlorinated solvent release sites.
-
Three-Dimensional Subsurface Flow, Fate and Transport of Microbes and Chemicals (3DFATMIC) Model
This model simulates subsurface flow, fate and transport of contaminants that are undergoing chemical or biological transformations. The model is applicable to transient conditions in both saturated and unsaturated zones.
-
Remediation Evaluation Model for Fuel hydrocarbons (REMFuel)
This model simulates the transient effects of groundwater source and plume remediation for fuel hydrocarbons.
-
BIOPLUME III
BIOPLUME III is a two-dimensional finite difference model for simulating the natural attenuation of organic contaminants in groundwater due to the processes of advection, dispersion, sorption, and biodegradation.
-
BIOSCREEN, Natural Attenuation Decision Support System
The model is designed to simulate biodegradation by both aerobic and anaerobic reactions.
-
Hydrocarbon Spill Screening Model (HSSM)
The model is intended to address the problem of LNAPL flow and transport from the ground surface to a water table aquifer.
-
Wellhead Protection Area (WHPA) Model
WHPA is a semi-analytical groundwater flow simulation program used for delineating capture zones in a wellhead protection area.
-
Vadose Zone Leaching (VLEACH)
VLEACH is a one-dimensional, finite difference model for making preliminary assessments of the effects on groundwater from the leaching of volatile, sorbed contaminants through the vadose zone.
-
Remediation Evaluation Model for Chlorinated Solvents (REMChlor)
This model simulates the transient effects of groundwater source and plume remediation. This model also calculates cancer risks posed by carcinogenic species.
-
Pesticide Analytical (PESTAN) Model
The PESTAN (Pesticide Analytical) model is a computer code for estimating the transport of
organic solutes through soil to groundwater. -
Visualizing Ecosystem Land Management Assessments (VELMA) Model
VELMA predicts the effectiveness of alternative green infrastructure scenarios for protecting water quality, and also estimates potential ecosystem service co-benefits and tradeoffs.
