PFAS LEACHATE REMOVAL PILOT EQUIPMENT & TESTING
The City of Nashua, New Hampshire is soliciting proposals from qualified vendors to conduct a pilot study
evaluating foam fractionation treatment technologies for the removal of per- and polyfluoroalkyl substances
(PFAS) from landfill leachate at the Four Hills Landfill, located at 840 West Hollis Street. The pilot study, planned
for summer 2026, will assess the effectiveness of candidate treatment systems and establish key design
parameters for a future full-scale PFAS treatment system. Vendors will provide equipment, labor, and materials
necessary to perform the on-site study under the oversight of the City, Sanborn Head, and the New Hampshire
Department of Environmental Services (NHDES). The study will evaluate PFAS removal efficiency, operational
performance, and waste generation while supporting the City's efforts to address PFAS compounds regulated by
USEPA and NHDES and improve long-term leachate management at the Facility.
