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.The program comes in two editions, Professional and Standard. The Professional edition is best suited for landfill design and the Standard edition is best suited for environmental remediation.Models are used to represent the subsurface lithology, containment systems, and contaminant source to be studied. These models can be used to study the effects of landfills, buried waste, spills, lagoons, barrier systems, etc. Each study area should be grouped into one or more projects. In addition to advective-dispersive transport, POLLUTEv7 can consider: ?Linear and non-linear sorption ?An initial concentration profile?Radioactive and biological decay ?Transport through fractures ?Passive sinks ?Phase changes?Time-varying propertiesPricesProfessional ..................................................................... $1695 USStandard ............................................................................. $995 USAnnual Maintenance ............................................................ $350 USFeatures?????T he d iffus ion coe ffic ien t, d is tribut ion coe ffic ien t, and phase change pa ram e te r can be spec if ied fo r each laye r.T he top boundary condition can be ze ro f lux , constan t concen tra t ion , or fin ite m ass.T he bo ttom bounda ry cond it ion can be ze ro f lux , constan t concen tra tion , fixed ou tflow, o r in finite th ickness.T he subsur face concen tra tions can be ca lcu la ted a t spec ified tim es o r the t im e o f the m ax im um concen tra tion can be au tom a t ica lly found by the p rog ram .
