Summary
BIOSCREEN-AT enhances groundwater contaminant transport modeling by adding an exact analytical solution to the existing Domenico solution. This allows for more accurate site-specific assessments and evaluation of Domenico
Area of Science:
- Environmental Engineering
- Hydrogeology
- Geochemistry
Background:
- BIOSCREEN is widely used for screening-level groundwater contaminant transport evaluation.
- Its graphical user interface makes it suitable for professional practice and education.
- The current version utilizes Domenico's approximate analytical solution (1987).
Purpose of the Study:
- To introduce BIOSCREEN-AT, an enhanced version of BIOSCREEN.
- To integrate an exact analytical solution for contaminant transport.
- To enable assessment of errors from the Domenico solution in site-specific applications.
Main Methods:
- Supplementing the Domenico solution with an exact analytical solution.
- Seamless integration of the exact solution within the BIOSCREEN interface.
- Development of BIOSCREEN-AT, a modified version of the BIOSCREEN program.
Main Results:
- BIOSCREEN-AT provides a direct method for calculating exact solutions to the transport equation.
- The enhanced version allows for the assessment of errors introduced by the Domenico (1987) solution.
- The software is available free of charge.
Conclusions:
- BIOSCREEN-AT offers a more accurate tool for groundwater contaminant transport modeling.
- The ability to compare exact and approximate solutions improves site-specific analysis.
- The enhanced software serves as a valuable educational and professional resource.
