DoD is currently managing hundreds of contaminated sediment sites. Although numerous sampling approaches exist to characterize contamination, they are often costly because of the need to collect a representative suite of samples to define the scope of the problem. Substantial analytical challenges also arise from complex mixtures. Sediment concentrations often inaccurately reflect exposures of receptors and corresponding risks. An alternative approach is the use of passive samplers that can provide a representative assessment of contaminant levels that accumulate over a period of time in proportion to those compounds to which the samplers have been exposed. This session highlighted the various passive sampling techniques and the benefits of using passive samplers to more accurately monitor bioavailability and contaminant mobility.
