Model multiple contaminant sources, for example to represent landfill extensions.

Vary properties with time, to simulate such effects as the failure of engineered systems.

  Simulate radioactive or biological decay.

  Include 1-D, 2-D, or 3-D fractures in any layer.

  Simulate secondary leachate collection systems using a passive sink in any layer.

  Model contaminant sources as surface boundary conditions or as a physically buried layer.

  Have the source concentration deplete with time or remain constant.

  Remove leachate using a leachate collection system.

  Specify the base as an aquifer impermeable, or zero concentration boundary condition.

 Specify both horizontal and vertical velocities and hydrodynamic dispersion coefficients for each layer.

 Model non-conservative species using linear sorption.

Graphical User Interface

  Create primary liner, composite liner (e.g. U.S. Subtitle D), or primary and secondary liner landfill models easily.

 Interactively create, edit, display, and print models.

 Execute models interactively or in batch mode, batch files can contain multiple models.

 Graphically display and print concentration vs time, distance or depth.

 Display graphs on most popular screen types, including SVGA.

 Print graphs on the most widely used printers, or store them as PCX format files.

 Import and convert POLLUTE data files.

 Access extensive context sensitive on-line help.
