Abstract

"Contaminant source release history is a necessary element of contaminant mass transport simulation in the saturated zone. The source release history is unknown at many sites, and many inverse models have been developed to define finite release histories. To define a likely domain of three source history parameters, a mass balancebased one dimensional approach is developed and tested by discretizing the spatial domain into bands. By incorporating the approach in a spreadsheet model, observed data is represented by both variable length and constant length bands of analysis. Each representation of observed data was tested to determine the most appropriate band geometry for improved model calibration and constant length bands results were more accurate than results of variable length bands. The source history parameter domains predicted by the model are then evaluated with Monte Carlo analysis. After datasets of artificial transport systems are developed and evaluated with the model, actual site data from a Superfund site is input to the model that provides reasonable results of the source history parameters. Limitations of the model require site characteristics that include negligible diffusion, a uniform regional flow field, and isotropic and homogeneous aquifer media"--Abstract, page iv.
