Application of a Water Quality Assessment Modeling System at a Superfund Site.

摘要

Water quality modeling and related exposure assessments at a Superfund site, Silver Bow Creek-Clark Fork River in Montana, demonstrate the capability to predict the fate of mining waste pollutants in the environment. A linked assessment system -- consisting of hydrology and erosion, river hydraulics, surface water quality, metal speciation, non-point source and groundwater mixing and transport models -- has been applied at the site to show the applicability of such modeling schemes and the complexities involved in the application. Some of the models had to be modified to match the requirements of this project. Graphs of the water quality parameters show good fit between the measured and predicted concentrations at some stations whereas substantial deviations are observed at other stations along the course of the stream.
