Description:
Successful prevention of public exposure to arsenic in ground-water resources impacted by natural sources or contaminated sites is dependent on scientifically-based strategies for site remediation and water resource management. Research within the National Risk Management Research Laboratory, Subsurface Protection and Remediation Division is directed towards building the fundamental basis for optimizing remediation technologies and management approaches to protect ground-water resources. Through various in-house and extramural research efforts, the Division actively pursues three key areas addressing arsenic contamination in ground-water systems: 1) elucidation of arsenic geochemistry at local and regional scales in various aqueous environments, 2) development of remediation technologies for subsurface systems, and 3) development of robust site characterization technologies for arsenic in liquid and solid matrices. The first research effort supports the need for reliable geochemical data for ground-water systems to support site remediation programs and to guide installation of water supply wells in geographically sensitive areas. The second research effort supports the need to implement technically feasible and cost-effective in-situ remediation technologies such as permeable reactive barriers and monitored natural attenuation. The last research effort supports the need for accurate, scientifically-defensible data used for characterization of subsurface systems and remedial performance monitoring. Together, these research components provide the Agency with a technically-defensible approach to protect human health.
