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.

Related Experiment Videos

  • 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.
