UNSPSC 77121508: Airborne particle monitoring

UNSPSC 77121508 Airborne particle monitoring (Commodity) encompasses laboratory testing and field sampling of environmental contaminants—primarily water quality analysis, air quality assessment, and site-specific hazard monitoring—as recently solicited by state and local governments. Recent opportunities show state and local buyers procuring water quality and microbiology testing (laboratory analysis of drinking water, wastewater, and dialysis facility water samples), Legionella testing and water management program implementation, indoor air quality testing (lead, mold, asbestos, and fungal assessment), stormwater and sewer spill monitoring with field sampling and analysis, and specialized atmospheric monitoring systems for hydrogen sulfide and methane detection at water and wastewater facilities. Issuing bodies include state environmental protection and health departments, county water and environmental agencies, municipal water and wastewater utilities, county school boards, special-purpose districts (transit authorities, housing authorities), and environmental management divisions within larger state facilities (correctional centers, developmental centers, state hospitals).

Geographic activity is concentrated in Florida, Georgia, Texas, Michigan, and Nevada, with additional solicitations from Illinois, New Jersey, Colorado, and New York. Representative recent opportunities include Santa Clara County's RFP for waterborne pathogen testing and environmental microbiology services supporting healthcare dialysis facilities (proposals due October 22, 2026); Forsyth County, Georgia's RFP for sanitary sewer flow monitoring services across a five-year term (proposals due October 15, 2026); Hillsborough County Public Schools' ITB for water and wastewater laboratory services including PFAS and drinking water compliance testing (bids due September 24, 2026); and the Nevada State Purchasing Division's RFP for WIIN water testing in schools and daycare facilities statewide with an estimated contract value of $528,535 (proposals due July 8, 2026). Laboratories must typically maintain ISO/IEC 17025 accreditation, EPA analytical method compliance, and specialized certifications (CDC ELITE for Legionella, NELAP for environmental analysis); contractors frequently manage both field collection and courier transport of samples in addition to analysis and regulatory reporting.
