Environmental restoration and closure of contaminated sediment sites is a top priority for the Department of Defense. Over the next five to ten years, identifying methods to establish long-term remedy success, reducing long-term management costs, and achieving site closure will be of primary concern. New investigation work will largely be associated with identifying recontamination sources within the local and regional watersheds and with emerging contaminants. SERDP and ESTCP convened a workshop to address this shift in site management priorities.
