FY 2015 STATEMENT OF NEED
Environmental Restoration (ER) Program Area
The overall objective of this Statement of Need (SON) was to improve our understanding and estimation of the impact of several natural processes on the fate and transport of contaminants in groundwater. Ultimately the goal of this SON is to quantify the long-term impacts of natural processes on contaminants in groundwater and to estimate the resulting contaminant attenuation rate. Specific objectives of interest include:
The projects listed below were selected to address the objectives of this SON. Additional information on individual projects can be found by clicking the project title.
Research should lead to improved site assessments and monitoring of long-term attenuation processes, and therefore more effective long-term management of contaminated groundwater sites. This information will be needed to: (1) obtain regulatory and other stakeholder concurrence that natural or enhanced attenuation is a viable, protective long-term remedial option; (2) support cost-benefit analyses of different methods for enhancing attenuation at a given site, if needed; and (3) track the progress of natural or enhanced attenuation. The resulting tools and understanding should improve the ability to assess the risks associated with residual contamination and manage those risks cost-effectively.
