NIGP 84508: Corrosion Test Equipment and Supplies

NIGP 84508 Corrosion Test Equipment and Supplies, an Item code, covers the chemical products and testing services state and local water utilities procure to control corrosion and protect potable water distribution systems from copper and lead contamination. The code captures NSF-certified corrosion inhibitor chemicals—typically ortho/polyphosphate blends meeting EPA and state environmental protection standards—along with field water testing services, expert consultation on lead and copper monitoring, technical data on product specifications and dosage rates, and related supplies required for application across multiple water treatment facilities. Issuing bodies soliciting under this code include county water resource and utilities divisions managing multi-facility systems serving municipal customers. The scope spans chemical supply contracts structured as competitively bid ITBs or RFQs with initial multi-year terms and optional renewals, vendor insurance and bonding requirements, and compliance obligations including federal prevailing wage standards when federal funding sources apply.

Volusia County Water Resources & Utilities Division in Florida recently issued ITB #26-B-60LS (due April 14, 2026) for ortho/polyphosphate corrosion inhibitor supply and field testing services across six water treatment facilities—Glen Abbey, Breezewood, Highland, Four Towns, Spruce Creek Fly-In, and Halifax Plantation WTPs—with annual volumes of approximately 3,380 gallons, multi-year contract structure, optional one-year renewals, and awards based on lowest total estimated annual cost including delivery and on-site consultation. The solicitation required comprehensive product documentation, shelf-life data, phosphate composition analysis, and references from three water utilities with prior corrosion control implementation experience. Payment terms include 20-business-day invoice settlement and provisions for annual price redetermination based on documented cost increases in labor, fuel, or materials.
