Madison Metropolitan Sewerage District is seeking PFAS consulting and monitoring support for wastewater, biosolids, and permit compliance.
- **Government buyer:** Madison Metropolitan Sewerage District (MMSD), a local government district in Madison, Wisconsin; no agency, sub-agency, or office is specified.
- **OEMs and vendors:** No OEMs or consulting vendors are named. The contracted laboratory is not identified.
- **Requested services:** Laboratory coordination and QA/QC; PFAS sampling and analysis; sampling-plan and SOP updates; investigations of hauled waste, septage, and collection-system sewersheds; biosolids sampling; data tools; staff training; annual reporting; and a cost-benefit comparison of in-house and outsourced testing.
- **Methods and monitoring:** The consulting scope calls for EPA Method 1633A analysis for up to 40 PFAS compounds. Permit-related reporting includes monthly effluent PFOA and PFOS results and annual biosolids reporting for all 40 compounds and combined PFOA+PFOS. The related sampling-plan attachment describes monthly influent and effluent sampling, quarterly Class B biosolids sampling, Class A cake sampling, and an equipment blank; its listed work totals 93 PFAS analyses and 5 percent-solids analyses.
- **Notable requirements:** Develop a dashboard combining historical and new results and a P99 calculator; maintain the District’s waste-acceptance tools; transfer routine data-review capabilities to MMSD staff; and ensure developed tools remain owned and accessible to the District. Industrial-user sampling is excluded from the collection-system sewershed effort.
- **Budget and term:** The anticipated consulting budget is $100,000 for the initial year, with a similar amount anticipated for each of two optional one-year renewals. The potential three-year total is approximately $300,000.
