BIOSCREEN

Description 

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:

Downloads

Installation program, help files, and instructions (ZIP)(1.3 MB)

US EPA. (1996) "BIOSCREEN, Natural Attenuation Decision Support System – User’s Manual, Version 1.3." Publication No. EPA/600/R-96/087. August 1996

  1. Refer to the user's manual for further instructions.
  2. Go to the Windows Explorer and create a directory on the C drive named BIOSCRN (C:\BIOSCRN).
  3. Download the user’s manual and installation zip file to the new BIOSCRN directory.
  4. Extract the contents of the installation zip file inside the C:\BIOSCRN directory.
  5. To run BIOSCREEN after installation, start Microsoft Excel and open the BIOSCRN4.xls file. Loading from within Excel is preferred to double-clicking the file name in the file manager.
