The POLLUTEv7 program provides fast, accurate, and comprehensive contaminant migration analysis capabilities. This program implements a one and a half dimensional solution to the advection-dispersion equation. Unlike finite element and finite difference formulations, POLLUTEv7 does not require a time-marching procedure, and thus involves relatively little computational effort while also avoiding the numerical problems of alternate approaches.

With more then fifteen years utilization in industry, POLLUTEv7 is a well tested contaminant migration analysis program which is widely used in landfill design and remediation. Landfill designs that can be considered range from simple systems on a natural clayey aquitard to composite liners, multiple barriers and multiple aquifers.

In addition to advective-dispersive transport, POLLUTEv7 can model:

  • non-linear sorption
  • radioactive and biological decay
  • transport through fractures
  • passive sinks
  • phase changes
  • time-varying properties

Models can be created from scratch, using the program Wizard or by selecting one of the many pre-created models: such as, Primary Liner Landfill, Primary and Secondary Liner Landfill, Vertical Migration, and Horizontal Migration.


Some of the features of POLLUTEv7 are:

  • New models can be easily created using either a blank model, the wizard, or a quick entry model.
  • A graphical diagram of the model is displayed as it is created.
  • Models can contain up to 200 layers.
  • Layers can contain 1, 2, or 3 dimensional fractures.
  • The diffusion coefficient, distribution coefficient, and phase change parameter can be specified for each layer.
  • The top boundary condition can be zero flux, constant concentration, or finite mass.
  • The bottom boundary condition can be zero flux, constant concentration, fixed outflow, or infinite thickness.
  • The subsurface concentrations can be calculated at specified times or the time of the maximum concentration can be automatically found by the program.
  • Radioactive or biological decay of the contaminant can be modeled.
  • An initial concentration profile at specified depths can be specified.
  • Freundlich and Langmuir non-linear sorption can be modeled.
  • Source, velocities, and layer properties can be varied with time (can be used model changes in the source, barriers, or flow patterns).
  • One or more passive sinks can be specified to model horizontal velocities in layers and the removal of contaminants.
  • Monte Carlo simulation can be used to evaluate the effects of uncertainty of model parameters.
  • Sensitivity analysis can be used to predict the expected range of concentration when parameter values are not known accurately.
