The City of Tucson Environmental Services is seeking multiple qualified firms to enter into an annual‑requirements contract for the supply, exchange, and disposal support of activated carbon used in groundwater pump‑and‑treat and soil‑vapor‑extraction remediation systems throughout the city. The contract covers provision of virgin coconut‑shell, bituminous‑coal, and re‑activated carbon meeting detailed physical‑chemical specifications, collection and laboratory analysis of spent carbon, transportation and on‑site replacement of carbon in vessels ranging from 5,000 lb to 20,000 lb capacities, and optional provision of 55‑gallon drum vessels and associated piping.

Offers are due September 16, 2026 at 2:00 PM local time via the City’s online procurement portal. • Annual‑requirements contract – multiple award, as‑needed deliveries. • Supply of activated carbon (virgin, bituminous, re‑activated) meeting strict mesh, surface‑area, hardness, ash, moisture, and iodine specifications. • Manage spent‑carbon sampling, laboratory analysis, manifesting, and transport to disposal/reactivation facilities. • Replace carbon in 5,000 lb, 20,000 lb vessels and 55‑gallon drum systems; provide optional piping and equipment (fork lifts, vacuum trucks, etc.). • Contractor responsible for all equipment, labor, and compliance with RCRA/State hazardous‑waste rules. • Evaluation based on method of approach, qualifications/experience, and price.
