The collective understanding gained through work funded by SERDP and ESTCP over the past 27 years has yielded important scientific knowledge that continuously helps DoD site managers. Nonetheless, the potential magnitude of the DoD’s chlorinated solvents liabilities will require a sustained and continuous effort to characterize, treat, monitor, and continuously manage risk at these sites. SERDP and ESTCP recently convened a workshop comprised of stakeholders, regulators, and scientists that reviewed the current state of the science and identified the most pressing needs for future research, demonstrations, and technology transfer with respect to chlorinated solvents remediation. Presentations on current state of affairs, potential application opportunities, in addition to what the participants considered remaining challenges in the remediation of chlorinated solvents sites will be presented during this session.
