Demonstration projects were sought for innovative technologies that specifically address the management, risk characterization, remediation, or monitoring of sediments impacted by per- and polyfluoroalkyl substances (PFAS), polycyclic aromatic hydrocarbons, polychlorinated biphenyls, heavy metals, chemicals of emerging concern, or mixtures containing these chemicals. Of particular interest were the following:

• Development of innovative, more cost effective in situ remedial technologies.
• Demonstrations that facilitate the application and commercialization of passive samplers.
• Demonstrations of tools or methodologies to evaluate amendment placement and remedy integrity.
• Demonstrations of new monitoring tools to reliably predict the long-term performance of remedies and the expected long-term risk reduction.
• Development of innovative technologies for sustainable dredged material disposal alternatives.

For those proposing projects addressing PFAS issues, review of the SERDP and ESTCP memo for specific quality assurance/quality control requirements for all projects addressing PFAS was recommended.

Impacted marine, estuarine, brackish, and freshwater sediments were of interest. Proposals addressing sediments contaminated with radionuclides were not considered. Proposed technologies should have completed all required laboratory work, although site specific treatability work prior to the field demonstration was acceptable. Specific Department of Defense (DoD) demonstration site(s) were allowed to be suggested in the pre-proposal, but were not required. Technologies and methods were sought that have well defined demonstration/validation questions to address. ESTCP demonstrations should have addressed technical and/or regulatory issues that inhibit the widespread use of the proposed approach across DoD. ESTCP supports demonstration at a scale sufficient to determine the operational performance of the remediation technology and to estimate its expected full-scale costs. Full-scale cleanup of specific sites was not performed under ESTCP.
