Description:
Field trials of innovative subsurface cleanup technologies require the use of integrated site characterization approaches to obtain critical design parameters, to evaluate pre-treatment contaminant distributions, and to assess process efficiency. This review focuses on the transition between typical levels of site and source characterization at host locations and the levels necessary to provide substantial proof of performance. Sampling plans should coordinate the collection of samples for aquifer property and contaminant measurements to minimize program costs and the disturbance of test site conditions. Performance monitoring approaches which utilize comparisons of cumulative mass removals or ?before-and-after' contaminant levels will require the use of proven site characterization methods and frequent sample replication. Replication of samples improves estimates of natural and experimental variability, which should enable more precise assessments of treatment efficiency and bolster the acceptance of evaluations by regulatory officials. Rapid field-based analytical approaches can play a major role in controlling technology evaluation project costs.
