The Department of Defense (DoD) must maintain a continuous effort to characterize, treat, monitor and manage any contaminated groundwater sites under its purview. While many sites have been cleaned up, more complex locations remain. In situ particulate/colloidal amendments are designed to adsorb contaminants in groundwater, which reduce their dissolved phase concentration. Before these amendments can be applied as a common approach at sites, more research is needed to understand the processes influencing the effectiveness and fate of particulate amendments for in situ treatment of chemicals of concern (COCs) in groundwater.
The following new SERDP projects aim to improve site management, specifically for groundwater sites impacted by chlorinated volatile organic compounds (CVOCs) and per- and polyfluoroalkyl substances (PFAS), by improving tools and guidance for applying commercially available amendments at DoD sites.
