Demonstration projects were sought for tools, methodologies, or technologies that can reduce the cost of managing the Department of Defense’s (DoD) long term liability associated with contaminated groundwater. Groundwater contaminants of concern include chlorinated solvents, energetic compounds, emerging contaminants of interest to DoD, or mixtures of these contaminants.

The primary focus of this topic area was innovative technologies and approaches for managing sites and the associated risks where contamination would persist for a significant period of time after an initial remedy was selected. The following areas were of interest:

• Cost-effective management tools or technologies to specifically address chlorinated solvent source zones in complex geological environments that cause persistent groundwater plumes.
• Cost-effective management tools or technologies to address groundwater contaminated with emerging contaminants, such as the per- and polyfluorinated alkyl substances. Such technologies also must address common co-contaminants with these emerging contaminants.
• Assessment of how to better combine existing or new technologies to address complex contaminated sites and make informed decisions on transitions from active remediation to passive technologies.
• Optimization, assessment, and/or long-term monitoring tools related to remediation of contaminated groundwater.

Funded projects will appear below as project overviews are posted to the website.
