REDACTED SAP single source determination

Laboratory-scale treatability testing of a proposed permeable absorptive barrier (PAB) will be conducted using an aquifer cell to assess the impacts of subsurface heterogeneity and multi-dimensional flow on performance of the PAB using DoN-specific site media. The primary objective of this work is to compare and evaluate downhole delivery, retention, and adsorption capacity of PAC+polyDADMAC. Two experiments will be conducted in separate aquifer cells (1 control + 1 PAC + polyDADMAC). Measurement of PFAS concentrations in aqueous samples will be based on a custom analytical method that employs large volume injection rather than solid phase extraction. Additional requested services involve drafting and submitting an experimental plan for the 2-dimensional flow cell studies, as well as assistance with drafting and submitting technology transfer materials such as peer-reviewed publications and final project reports. Ultimately, these materials will be used to benefit Navy practitioners in their implementation of this technology at a variety of other sites that may require this specific treatment for PFAS.
