NIGP 88576: Odor Control Chemicals, etc.

NIGP 88576 Odor Control Chemicals, Etc., an Item code, covers chemical treatments and services for hydrogen sulfide odor and corrosion control in municipal wastewater collection and treatment infrastructure. State and local governments buy bioxide and ferrous salt chemical additives injected directly into sewer systems, magnesium hydroxide slurry delivered in bulk to distributed storage tanks, activated carbon rental units for air treatment at wastewater facilities, and specialized mulch bed media for odor control at vacuum stations. Recent solicitations show a mix of issuing bodies: city public utilities departments (Dallas, Griffin, Tallahassee, Austin, Meriden, Flowery Branch, Waterford) dominate the code's activity, though county water resources departments (Gwinnett County in Georgia, Sarasota County in Florida) and state water agencies (California Department of Water Resources) also procure under it. Work is typically solicited as fixed-price supply contracts for chemical products on annual or multi-year terms, with occasional service agreements layering installation, monitoring, maintenance, and emergency response on top of material delivery.

Geographic activity clusters in the Southeast (Florida, Georgia, Connecticut) and extends to Texas and California. Sarasota County issued IFB 262888RM on July 6, 2026 (due August 7, 2026) for five-year odor control mulch bed media refurbishment and replacement at nine vacuum stations, with annual maintenance and year-five complete replacement under firm-fixed rates by site.
