Natural Attenuation Decision Support System (BIOSCREEN)
Entry ID: USEPA_BIOSCREEN
Abstract: 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
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 (approach used by BIOPLUME models).
The model is designed to simulate biodegradation by both aerobic and unaerobic
reaction. It was developed for the Air Force Center Environment Excellence
(AFCEE) Technology Transfer Division at Brooks Air Force Base by Groundwater
Services, Inc., Housten, Texas.
