UNSPSC 77121700: Water pollution

UNSPSC 77121700 Water pollution is a Class code that encompasses laboratory testing services, wastewater treatment facility support, stormwater compliance work, and aquatic species survey and relocation services for state and local environmental protection agencies. State and local governments use this code to procure analytical testing for contamination identification, permit compliance documentation, and data supporting environmental remediation and regulatory enforcement decisions. Recent solicitations show municipalities and water authorities acquiring acute and chronic aquatic toxicity testing, dewatered sludge analysis, MS4 (Municipal Separate Storm Sewer System) stormwater compliance consulting, alum sludge removal and disposal, drinking water laboratory testing, and freshwater mussel surveys with species relocation capabilities.

Activity under the code spans Connecticut, Georgia, Massachusetts, Nevada, Texas, and Utah, with heavy recent concentration in Connecticut and California.
