PFAS Leachate Removal Pilot Equipment & Testing

The City of Nashua, New Hampshire Division of Public Works is issuing a Request for Proposal to solicit qualified vendors to conduct a pilot study evaluating foam fractionation treatment technologies for removing per- and polyfluoroalkyl substances (PFAS) from landfill leachate at the Four Hills Landfill. The pilot study, scheduled for summer 2026, will assess treatment system effectiveness and establish design parameters for a future full-scale PFAS treatment system addressing the facility's discharge of approximately 16,400 gallons per day of leachate to the City's wastewater treatment plant. Vendors must provide all equipment, labor, and materials necessary to perform the on-site study under oversight of the City, Sanborn Head consulting firm, and the New Hampshire Department of Environmental Services. The three-phase pilot study, estimated to take six weeks, includes Phase I concept confirmation and efficiency evaluation (24-48 hours), Phase II operation optimization with variable conditions testing (multiple 24-48 hour periods), and Phase III long-term operation testing for up to three weeks. Proposals will be evaluated based on qualifications and experience (50%), overall impression and quality of proposal (20%), and cost proposal (30%). An optional pre-bid meeting is scheduled for March 18, 2026, at 10:00 a.m. at the Division of Public Works Administration Building with virtual Zoom participation available. Vendor questions must be submitted by March 24, 2026, at 10:00 a.m., with answers posted by March 26, 2026, at 3:00 p.m. Proposals are due by March 31, 2026, at 2:00 p.m. to City Hall Purchasing Department, submitted electronically via Bonfire or as paper copies with digital USB drives.

The RFP document does not specify any set-aside designations or restrictions limiting response to particular types of organizations, disadvantaged enterprises, or socioeconomic categories. No incumbent vendors or current contractors are identified in the procurement materials. Vendors must demonstrate experience with recently completed similar projects through submitted references and must complete a questionnaire addressing full-scale system design parameters and cost considerations. Insurance requirements include General Liability coverage of $1,000,000 per occurrence/$2,000,000 aggregate, Combined Single Limit Automobile Liability of $1,000,000, and Workers' Compensation Coverage per New Hampshire statutes ($100,000/$500,000/$100,000), with the City named as additional insured. All proposals are binding for 90 days following the deadline, and the City anticipates selecting a vendor in mid-April 2026 with contract execution by mid-May 2026.
