A Modern Approach to Accelerating Basewide PFAS Remedial Investigations (RIs) via High-Resolution Site Characterization (HRSC) and Flux-Based Conceptual Site Model (CSM) Development

PFAS is top priority in environmental assessment and remediation for the Department of Defense (DoD), with investigations ongoing or planned at over 700 installations nationwide. Remedial Investigations (RIs) are a critical step in the CERCLA process to defining the nature and extent of contamination to facilitate future risk assessment and remedial action (i.e. Feasibility Study). The evolving nature of PFAS science and regulations, as well as intensified stakeholder (regulatory and public) engagement, may slow progress and completion of RIs. DoD’s time-critical need to improve cost-effective management of PFAS and mitigate ongoing or potential risk to human health and/or the environment cannot be supported by the traditional RI approach and timeline. As demonstrated by BEM at multiple DoD Installations and detailed in this presentation, a TRIAD-like high-resolution characterization approach, supported by innovative stakeholder engagement strategies and technologies (online dashboard), has proven successful in supporting DoD priorities and accelerating interim decision making.
