The Department of the Army (AMC‑ACC, 419th CSB, MICC‑FT Drum) is issuing a Total Small Business Set‑Aside (FAR 19.5) solicitation (W911S‑22‑U‑2775) for the procurement of three distinct boiler‑water‑treatment chemical solutions. All products must be supplied in equal monthly deliveries over a 12‑month period, with the following annual quantities and specifications: 1. **Aqueous alkali‑salt solution – 3,150 lb/yr** – a hazy, colorless‑to‑yellow liquid with a slight ammoniacal odor, containing 7‑13 % sodium sulfite, 3‑7 % sodium hydroxide, and 1‑5 % diethyl ethanolamine. The solution must be highly corrosive, alkaline (pH ≈ 14), specific gravity 1.181, water‑soluble, and have a boiling point >212 °F (100 °C). 2. **Aqueous dispersion – 2,700 lb/yr** – a transparent, colorless, odorless liquid, non‑viscous to slightly viscous, free of hazardous substances at the required concentration. Required properties are alkaline pH ≈ 11.4, specific gravity 1.192, water‑soluble, and boiling point >212 °F. 3. **Aqueous inorganic‑salt mixture – 1,180 lb/yr** – a transparent liquid with a light orange‑to‑pink‑purple hue and a sulfurous odor, containing 15‑40 % sodium bisulfite and 3‑7 % sodium sulfite. The mixture must be acidic (pH ≈ 5.9), specific gravity 1.08, fully water‑soluble, and have a boiling point >212 °F. Responses are due by 16:30 LMT on 19 Mar 2026. Technical and delivery requirements are detailed in the solicitation; point of contact is Davis Harp (davis.r.harp.civ@army.mil, 870‑540‑3045).
