New Jersey WSC Archived Projects
Few studies have evaluated or compared contaminant mass removal by Pump-and-Treat (P&T), Monitored Natural Attenuation (MNA), or Enhanced Biodegradation (EB) in fractured-rock aquifers, partly because of the perceived hydrogeologic complexity, the lack of understanding of the processes controlling the migration and transformation of contaminants, and the lack of sufficient field data for calculating mass removed. There is a critical need for this evaluation, to determine the relative efficiencies of P&T, MNA, and EB remedial strategies in fractured rock. The objective of this project is to evaluate and compare CVOC removal and destruction from the well-characterized NAWC site by three remediation technologies: P&T, MNA, and EB.
START DATE: 19-DEC-2006
END DATE: 30-SEP-2009
PROJECT NUMBER: 4555CXG
STUDY OBJECTIVES:
The objective of this project is to evaluate and compare CVOC removal and destruction from the well-characterized NAWC site by three remediation technologies: P&T, MNA, and EB. We also aim to better understand the hydrogeologic and biogeochemical mechanisms that control contaminant removal by P&T and destruction by MNA and EB in fractured rock, to enable transferability of the NAWC results for improving remediation costs and efficiency at other DoD facilities that have CVOC contamination in fractured-rock aquifers.
STATEMENT OF PROBLEM:
Few studies have evaluated or compared contaminant mass removal by Pump-and-Treat (P&T), Monitored Natural Attenuation (MNA), or Enhanced Biodegradation (EB) in fractured-rock aquifers, partly because of the perceived hydrogeologic complexity, the lack of understanding of the processes controlling the migration and transformation of contaminants, and the lack of sufficient field data for calculating mass removed. There is a critical need for this evaluation, to determine the relative efficiencies of P&T, MNA, and EB remedial strategies in fractured rock. The Naval Air Warfare Center (NAWC), West Trenton, NJ, is well suited for such an investigation. At this site, there is existing detailed characterization of the fractured sedimentary rock hydrogeologic framework and spatial distribution of chlorinated volatile organic compound (CVOC) contamination, as well as ongoing investigations of subsurface properties and rates that play key roles in mass removal processes. This information has paved the way for a focused assessment and comparison of CVOC mass removal by P&T, MNA, and EB.
