NIGP 26984: Skin and Mucous Membrane Agents

NIGP 26984 Skin and Mucous Membrane Agents, an Item code, covers water treatment and wastewater coagulation chemicals that state and local governments procure for municipal water systems and treatment facilities. Recent state and local solicitations under this code reflect purchasing for aluminum-based coagulants and flocculants — specifically aluminum chlorohydrate (ACH), aluminum chlorohydrate sulfate (ACH-S), and liquid aluminum sulfate (alum) — used to remove contaminants and phosphorus from drinking water and wastewater streams. One medical-sector exception appears in the recent activity: the City of Tampa Fire Rescue Department's April 2026 ITB for medical aid supplies including antiseptic sprays and first aid items, though this represents a secondary application area outside the primary water-treatment focus. Water utilities and municipal water districts dominate as issuing bodies, with the City of Scottsdale Water Resources Department appearing twice (for ACH 50% solution and ACH-S) and the North Texas Municipal Water District and City of Austin each posting once.

Recent activity concentrates in Texas and Arizona. The City of Austin issued IFB 2200 CSH1061 on July 27, 2026, requesting bids on liquid aluminum sulfate (47%–49% concentration) for its wastewater treatment facility, with bids due August 25, 2026 and an estimated annual quantity of 179,200 gallons; the solicitation applies a 5% local business preference discount (3% for small business) on bids under $500,000 and requires NSF approval and AWWA B403 compliance. The City of Scottsdale Water Resources Department posted 27RFP105 on October 1, 2026, for Aluminum Chlorohydrate 50% solution at its Chaparral Water Treatment Plant, with proposals due October 30, 2026. The North Texas Municipal Water District solicited bids for an annual Aluminum Chlorohydrate contract (IFB 26159B, due July 29, 2026). Supply, delivery, storage capacity maintenance (including distributed inventory across multiple facilities), manufacturer or authorized-dealer status, product certification, and municipal reference provision are recurring requirements across water-sector opportunities.
