NIGP 39529: Continuous Forms, Carbon Interleaved

NIGP 39529 Continuous Forms, Carbon Interleaved is an Item code that describes granular activated carbon (GAC) media used in municipal water treatment and filtration systems. State and local governments procure this commodity for replacement and maintenance of advanced water treatment facilities, where spent carbon media must be removed, disposed of, and replaced with new material to maintain water quality and system performance. The work involves both supply of the GAC product and the labor-intensive service of removal, disposal, and installation at operating treatment plants.

The City of Rio Rancho, New Mexico recently solicited bids under this code via IFB 27002UT for removal and replacement of granular activated carbon media in four 9,800-gallon tank vessels at its Advanced Water Treatment Facility, with bids due August 11, 2026. The scope included disposal of spent GAC and supply and installation of new media under oversight of Jacobs and the city's operations and maintenance staff. Activity under this code appears limited in recent state and local postings, with no other recent opportunities evident in current sources.
