BIOSCREEN is a screening model that simulates remediation through natural attenuation of dissolved hydrocarbons at petroleum fuel release sites. The model is designed to simulate biodegradation by both aerobic and anaerobic reactions.
This software, programmed in the Microsoft Excel spreadsheet environment and based on the Domenico analytical solute transport model, has the ability to simulate advection, dispersion, adsorption, and aerobic decay, as well as anaerobic reactions that have been shown to be the dominant biodegradation processes at many petroleum release sites. BIOSCREEN includes three different model types:
- Solute transport without decay
- Solute transport with biodegradation modeled as a first-order decay process (simple, lumped-parameter approach)
- Solute transport with biodegradation modeled as an instantaneous biodegradation reaction with multiple soluble electron acceptors including dissolved oxygen, nitrate, and sulfate
BIOSCREEN-AT is a screening-level model developed for and distributed by the EPA that simulates remediation through natural attenuation of dissolved hydrocarbons at petroleum fuel release sites.
The computer program (HST3D) described in this report simulates heat and solute transport in three-dimensional saturated ground-water flow systems.
A model for 2D or 3D saturated-unsaturated, variable-density ground-water flow with solute or energy transport.
BIOCHLOR is a screening model that simulates remediation by natural attenuation of dissolved solvents at chlorinated solvent release sites.
