Park Water Treatment Plant PFAS Study 1

The City of Salisbury seeks qualified engineering firms to conduct a comprehensive PFAS source‑tracking and treatment‑planning study for the Park Water Treatment Plant. The scope is divided into six major tasks: capture‑zone analysis, groundwater flow modeling (including WHPA updates), design of a PFAS monitoring‑well network, evaluation of PFAS treatment technologies, alternate‑site analysis for plant relocation, and delivery of a final technical report with implementation recommendations. Proposals are evaluated on price, technical approach, experience/qualifications, and past performance, with a total of 100 points possible. The solicitation requires electronic submission of cost and response files, adherence to insurance requirements, and completion of multiple standard forms (SF‑330, affidavits, etc.). • Capture‑zone analysis using semi‑analytical models for multiple travel‑time zones. • Groundwater flow model (MODFLOW/WhAEM) development, calibration, and WHPA map updates. • Design and cost estimate for a PFAS monitoring‑well network on City property. • Evaluation of GAC, ion exchange, reverse osmosis, and emerging PFAS‑treatment technologies. • Alternate‑site feasibility study (up to three sites) with flood‑plain, dam‑break, and constructability analysis. • Final technical report consolidating all findings, cost estimates, and an implementation plan.
