This study is an evaluation of the potential environmentalimpacts of contaminated groundwater from the ASARCO metals refiningfacility adjacent to the Missouri River in Omaha, Nebraska. Surfacewaters, sediments, and sediment pore waters were collected from theBurt-Izard drain, which transects the facility, and from the Missouri Riveradjacent to the facility. Groundwater was also collected from thefacility. Waters and sediments were analyzed for inorganic contaminants,and the toxicity of the waters was evaluated with the Ceriodaphnia dubia7-day test. Concentrations of several elemental contaminants were highlyelevated in the groundwater, but not in river sediment pore waters. Leadconcentrations were moderately elevated...
The estimation of surface-subsurface water interactions is complex and highly variable in space and time. It is even more complex when it has to be estimated in urban areas, because of the complex patterns of the land-cover in these areas. In this research a modeling approach with integrated remote sensing analysis has been developed for estimating water fluxes in urban environments. The methodology was developed with the aim to simulate fluxes of contaminants from polluted sites. Groundwater pollution in urban environments is linked to patterns of land use and hence it is essential to characterize the land cover in a detail. An object-oriented classification approach applied on high-resolution satellite data has...
