Long-Term Water Quality and Treatment Master Plan Report

This document is a master planning report prepared for the Washington Suburban Sanitary Commission (WSSC) in Maryland, addressing long-term water quality and treatment strategies. The report outlines comprehensive assessments of water quality challenges, treatment capabilities, and infrastructure needs across WSSC's service area. The document serves as a foundational planning tool for the Potomac Water Filtration Plant (WFP) Water Quality/PFAS Pilot Project, which involves progressive design-build services for designing, constructing, and operating a PFAS (per- and polyfluoroalkyl substances) pilot treatment plant. The pilot project represents WSSC's strategic response to emerging contaminant concerns and regulatory requirements. Responses for the pilot project must be submitted via WSSC's eProcurement Portal at https://procurement.opengov.com/portal/wsscwater no later than 2:00 pm on Tuesday, December 1, 2026, with late submissions not accepted.

The master plan report identifies water quality treatment priorities, infrastructure requirements, and operational considerations necessary to inform the design and implementation phases of the PFAS pilot plant. The report likely contains technical analyses, capital improvement projections, and treatment methodology recommendations that will guide vendor selection and project execution. Funding for the pilot project would derive from WSSC's capital improvement budget and may involve state or federal water quality grants related to emerging contaminant mitigation. The pilot phase is intended to evaluate PFAS treatment effectiveness and operational feasibility before potential full-scale implementation at the Potomac WFP or other WSSC facilities.
