NIGP 88540 Chlorinating and Oxidizing Agents: Bromohydantoins, Chloroisocyanurates, Hypochlorites, Etc. (For Swimming Pool Disinfection), an Item code, encompasses the procurement of pool and water-treatment disinfection chemicals that state and local governments purchase to maintain compliance with health department water-quality standards. Recent solicitations show purchasing concentrated on sodium hypochlorite solutions (12.5% and other concentrations), calcium hypochlorite tablets and granules, chlorine compounds, cyanuric acid stabilizers, and related oxidizing agents for swimming pools, splash pads, interactive water features, and water treatment operations. Issuing bodies span school districts (Pinellas County Schools, Marion County Schools, Parkway School District), cities (Detroit, Austin, Palo Alto, Meriden, Dallas, Tucson, Milpitas, Griffin), counties (Milwaukee, Gwinnett), special-purpose water districts (Clean Water Services, Palo Alto Regional Water Quality Control Plant), and municipal park and recreation departments. Cities and school districts dominate recent activity, with repeated solicitations from Austin, Detroit, Palo Alto, and Dallas. Contracts range from single-product purchases (sodium hypochlorite for pool disinfection) to bundled chemical suites covering shock treatments, pH adjusters, stabilizers, and filter media, often combined with technical service delivery, equipment installation, or maintenance labor.

Activity concentrates in Florida (multiple school and city facilities), California (Austin, Palo Alto, Milpitas), Texas (Austin, Dallas), the Midwest (Milwaukee, Detroit, Parkway District), and the Southeast (Georgia, Connecticut).
