POLLUTE - finite-layer contaminant migration model - landfill design
POLLUTE Categories: landfills, solute transport models - saturated zone, solute transport models - unsaturated zone, fractured systems models, solid waste management
POLLUTE can be used for fast, accurate, and comprehensive contaminant migration analysis. POLLUTE implements a "1½-dimensional" solution to the advection-dispersion equation. Unlike finite-element and finite-difference formulations, POLLUTE doesthe numerical stability problems of alternate approaches. With more then ten years utilization in industry, POLLUTE is a well-t not require a time-marching procedure and thus involves relatively little computational effort while also avoiding ested contaminant migration analysis program which is widely used in landfill design Internationally. Landfill designs that can be considered range from simple systems on a natural clayey aquitard to composite liners with multiple barriers and multiple aquifers. In addition to advective-dispersive transport, POLLUTE can consider adsorption, radioactive and biological decay, phase changes, and transport through fractures. The Graphical User Interface makes the editing, execution, and printing of data easy and flexible. This interface also has options to quickly design landfills with primary composite barriers (e.g., U.S. Subtitle D), or primary and secondary composite barriers (e.g., U.S. Subtitle C).
