UNSPSC 77121700: Water pollution

UNSPSC 77121700 Water pollution is a Class code under which state and local governments procure water quality technical consulting, laboratory testing and analysis, environmental remediation and monitoring services, and related compliance support. Recent opportunities show state and local issuing bodies soliciting specialized services tied to regulatory compliance—water quality technical consulting for transportation authority environmental programs; acute and chronic aquatic toxicity testing for wastewater discharge permits; drinking water and wastewater laboratory analysis for Safe Drinking Water Act and Clean Water Act compliance; groundwater and soil vapor monitoring under Central Valley Regional Water Quality Control Board requirements; stormwater MS4 permit compliance support; and treatment plant sludge removal and disposal. Transportation authorities, state departments, counties, cities, school districts, and state environmental agencies all buy under this code. California Department of Transportation (Caltrans) and state environmental agencies are standout repeat buyers, issuing multiple small business set-aside contracts for water pollution control program work and environmental testing services.

Recent activity concentrates heavily in California, Florida, and Connecticut, with additional opportunities in Georgia, North Carolina, Nevada, Massachusetts, and Texas. Representative recent solicitations include the Orange County Transportation Authority's RFP for water quality technical consulting to support its M2 Environmental Cleanup Program (proposals due November 9, 2026, five-year contract valued at $300,000 on a time-and-materials basis); Hillsborough County Public Schools' ITB for Water and Wastewater Laboratory Services covering wastewater process control, groundwater monitoring, drinking water compliance testing, and sample transportation (bids due September 24, 2026); the State of California Military Department's IFB for groundwater and soil vapor gas monitoring and reporting at Stockton Field Maintenance Shop #24 (bids due October 7, 2026, twelve-month scope with single lump-sum pricing); the City of Palm Bay's ITB for Laboratory Testing and Related Professional Services covering water analysis, wastewater testing, and industrial pretreatment monitoring (bids due October 6, 2026, incumbent contractor Advanced Environmental Laboratories, Inc.); and the Town of Simsbury's RFP for MS4 stormwater compliance and industrial stormwater permit services (proposals due July 14, 2026, three-year term with two optional one-year extensions). The code attracts both large environmental consulting firms and specialized water testing laboratories and shows steady procurement activity throughout 2026.
