Contaminated Sediment Core Profiling

Impact/Purpose:
Sediment core profiling is often utilized during preliminary environmental investigations to characterize a site, identify contaminants of concern present, and provide an estimate of sediment toxicity. Vertical sediment profiling is also useful to monitor remediation and mitigation operations at locations with contaminated sediments. Overall, when field sampling strategies utilizing sediment core profiling are properly designed and executed, it can provide a clear, unambiguous record of the spatial and temporal distribution of contaminated sediments. The information presented in this book chapter will be useful for scientists and regulators involved with assessing and managing the ecotoxicological risk at sites where contaminated sediment core profiling may be of use.
Description:
Evaluating the environmental risk of sites containing contaminated sediments often poses major challenges due in part to the absence of detailed information available for a given location. Sediment core profiling is often utilized during preliminary environmental investigations to characterize a site, identify contaminants of concern present, and provide an estimate of sediment toxicity. Vertical sediment profiling is also useful to monitor remediation and mitigation operations at locations with contaminated sediments. Overall, when field sampling strategies utilizing sediment core profiling are properly designed and executed, it can provide a clear, unambiguous record of the spatial and temporal distribution of contaminated sediments.
