BIOSCREEN is an easy-to-use screening model which simulates remediation through
natural attenuation (RAN) of dissolved hydrocarbons at petroleum fuel release sites.
Application: Three-dimensional contaminant transport for dissolved phase hydrocarbons in saturated zone under the influences of oxygen, nitrate, iron, sulfate, and methane limited biodegredation.
The 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, first order decay and instantaneous reactions under aerobic and anaerobic conditions that have been shown to be the dominant biodegradation processes at many petroleum release sites.
BIOSCREEN includes three different model types:
