Abstract |
Currently, a large gap exists between theoretical advances in the understanding of how various natural processes affect subsurface contaminant transport, and our ability to translate those advances into practical applications. The lack of truly representative and reliable field tests for important parameters that are used to characterize these natural processes is a major stumbling block, as is the reluctance to use state-of-the-art tools and information in conventional site investigations. Incorporation of state-of-the-art techniques in site characterization efforts should be encouraged, however, as total costs of investigating and remediating a site would be lowered due to the improved remedial action designs that would result. |
