UNSPSC 60104201: Water testing chemicals

UNSPSC 60104201 Water testing chemicals is a Commodity code that encompasses the supply of treatment and process-control chemicals for potable water systems, wastewater treatment plants, and water reclamation facilities — not laboratory reagents or analytical test kits. State and local governments buy bulk liquid and solid chemical products under this code to support ongoing operations at water treatment plants and wastewater facilities, including coagulants (aluminum sulfate, polyaluminum chloride), disinfectants (sodium hypochlorite, chlorine, liquid oxygen), pH adjusters (sodium hydroxide, caustic soda), dewatering polymers for biosolids handling, and specialty chemicals such as sulfur dioxide, ammonium sulfate, and hydrogen peroxide. The issuing-body mix spans municipal water departments and utilities (cities of Waco, Tempe, Cocoa, Meriden, Cartersville, Valdosta, Santa Cruz, and DeLand; Rockland County Sewer District; Cobb County-Marietta Water Authority; Macon Water Authority; Clean Water Services in Oregon; Pike County Water & Sewerage Authority in Georgia), county water and environmental agencies (Gwinnett County, Collier County), state environmental services (Maryland Environmental Service), and special-purpose districts (Waco, Collier County, various Georgia authorities). Activity is concentrated in the Southeast and Southwest — Florida, Georgia, Texas, and Arizona see the most recent solicitation volume, with secondary activity in Maryland, Oregon, Connecticut, and California.

Recent opportunities demonstrate the breadth of chemical procurement across treatment and solids-handling operations. Collier County is requesting competitive sealed bids for countywide chemicals across 29 line items for water and wastewater treatment with an estimated historical annual spend of approximately $4 million (ITB 268705, bids due November 13, 2026). The City of Waco has posted a series of separate IFBs and RFBs for individual chemical supplies — liquid chlorine in one-ton and 150-pound containers (RFB 2026-042, bids due August 21, 2026), sodium hydroxide in two strength grades (RFB 2026-040, bids due August 20, 2026), cationic dewatering polymers for two treatment plants (RFB 2026-043 and RFB 2026-044, bids due August 21, 2026), liquid aluminum sulfate, liquid oxygen, liquid polyaluminum chloride, and liquid ammonium sulfate — all with delivery to municipal water and wastewater treatment facilities on an F.O.B. destination basis. The City of Cocoa is requesting sealed bids for liquid sodium hypochlorite conforming to ANSI/AWWA B300 and NSF 60/61 standards with 72-hour delivery to six municipal facilities (ITB B2617COC, bids due September 23, 2026). Hillsborough County Public Schools is procuring water and wastewater laboratory services covering 32 line items of testing (CBOD5, TSS, fecal coliform, VOCs, pesticides, lead and copper, PFAS) with estimated annual usage ranging from 2 to 850 tests per category (ITB 26311A-ITB-MST, bids due September 24, 2026). Maryland Environmental Service continues to solicit liquid emulsion polymer for biosolids dewatering at correctional-institution and municipal treatment plants (SBR Procurement 1272155 and 1272145, bids due November 2026). The code shows sustained quarter-over-quarter procurement activity across municipal, county, and water-authority buyers with firm pricing, NSF and AWWA compliance requirements, and strict delivery and performance standards typical of public-utility operations.
