The objective of this project is to foster broader understanding and acceptance of the EMNR remedy through demonstration and validation of performance and cost-effectiveness at DoD contaminated sediment sites. Broader use of EMNR has several potential benefits to DoD and the broader scientific community, including reduced material costs compared to conventional isolation capping andor dredging, accelerated recovery and reduced long-term monitoring costs compared to MNR, elimination of removal and disposal costs associated with dredging, and eliminationreduction of impacts to benthic communities compared to conventional isolation capping and dredging remedies. Because most of the contaminated sediment at NavyUSMC and DoD sites often falls into the moderately contaminated classification, EMNR has the potential to find widespread application, particularly as an adjunct to other more active remedies that might be applied in areas of higher contamination at the site. With cleanup costs estimated to exceed 1B, the broader application of EMNR could save DoD tens to hundreds of million dollars. EMNR also could facilitate more rapid acceptance and site closure for DoD sites where MNR is the most appropriate remedy but agency resistance or concerns make MNR acceptance difficult.
