Remedial Investigation (RI) and Optional Feasibility Study (FS) for Per- and Polyfluoroalkyl Substances (PFAS)

This Sources Sought Notice seeks market research to gauge small‑business capability for a five‑year, firm‑fixed‑price environmental remediation effort focused on PFAS at a former Base Realignment and Closure (BRAC) site in Monterey, California. The effort will include a Remedial Investigation (RI) and an Optional Feasibility Study (FS) under CERCLA, requiring extensive field characterization, waste management, specialized comparative studies, and comprehensive reporting. The government will use the responses to determine the acquisition strategy and potential small‑business set‑aside. • Perform subsurface drilling, groundwater monitoring, and strict PFAS sampling protocols. • Conduct comparative studies of passive sampling versus low‑flow techniques and evaluate GAC treatment plant efficacy. • Deliver detailed RI reports, risk assessments, stakeholder presentations, and feasibility study documentation complying with CERCLA and related regulations.
