Reactive Capping Mat Development and Evaluation for Sequestering Contaminants in Sediments

摘要

Strategic Environmental Research and Development Program (SERDP) Project Number ER-1493 (Reactive Capping Mat Development and Evaluation for Sequestering Contaminants in Sediment) was implemented by a collaborative team from the NAVFAC Engineering Service Center (NAVFAC ESC), Science Applications International Corporation (SAIC) and the University of New Hampshire (UNH). The project consisted of developing a reactive geotextile mat system to serve as a chemically effective, mechanically stable, and cost efficient technology for reducing ecological risks by sequestering contaminants in sediment. Use of reactive mat systems could provide an alternative to costly dredging and offsite disposal, and a more stable solution for standard capping approaches. The mat system, if deemed successful, would be deployed in a wide variety of environmental settings to prevent both metals and organic contaminants from entering overlying surface waters while simultaneously allowing both groundwater flux and surficial biological colonization.
