Deploying the Remedy and Recontamination Assessment Array frame developed under ER-2537

Site characterization and long-term monitoring remain a significant part of remediation life-cycle costs for all Department of Defense (DoD) sites. The need to develop environmentally-protective and cost-efficient characterization tools for remedial investigations was highlighted in the first Workshop Report (2004). Over time, SERDP and ESTCP investments broadened to include research and demonstrations that could significantly improve the ability to address contaminant source exposure, transport and fate, and stormwater monitoring challenges at DoD coastal sites.  New tools, and demonstration/validation of those tools, were needed to support in-place remediation technologies such as Monitored Natural Recovery, Enhanced Natural Recovery, and sediment amendments, such as Activated Carbon.

Projects to date include means to measure in-place contaminants, tools to monitor the flux of contaminants in groundwater to sediments, improved ways to measure and predict bedded-sediment stability, forensics approaches to fingerprint PCB sources, additional tools to link off-site sources to sediment recontamination, and in-place tools to assess ecological risks in sediments.
