Hill Brothers Chemical Company

Hill Brothers Chemical Company is a for-profit manufacturer and supplier of industrial and water treatment chemicals based in Phoenix, Arizona, specializing in providing critical chemical infrastructure support to various federal agencies. The company delivers essential chemicals such as chlorine gas, sodium hypochlorite, sodium bisulfite, and aluminum chloride polymer to government facilities, particularly within the Department of the Interior. Its federal contract portfolio demonstrates expertise in supporting water and wastewater treatment operations across multiple national parks, water management installations, and federal research facilities.

Through federal contract awards, Hill Brothers Chemical Company has consistently provided chemical supplies to agencies like the Bureau of Reclamation, National Park Service Intermountain Region, International Boundary and Water Commission, and USDA's Plant Protection and Quarantine division. The company has been awarded numerous contracts ranging from small purchase orders to large blanket purchase agreements, with contract values typically between $20,000 and $250,000. Many of these contracts have been designated as total small business set-asides, indicating the company's status as a small business enterprise. The chemical supplies have been critical for maintaining water infrastructure at locations including Grand Canyon National Park, Yuma Desalting Plant, and various water treatment facilities across the southwestern United States.

Hill Brothers Chemical Company holds three significant Indefinite Delivery Vehicles (IDVs): a $1,800,000 Indefinite Delivery Contract with the Bureau of Reclamation for bulk chemical delivery to the Yuma Desalting Plant, a $500,000 Indefinite Delivery Contract with the Bureau of Reclamation for Yuma Area Office bulk chemicals, and a $1,000,000 Blanket Purchase Agreement with the National Park Service Intermountain Region for water and wastewater treatment chemicals. These IDVs, set to expire between 2027 and 2030, provide federal agencies flexible procurement mechanisms for acquiring essential chemical supplies. The contracts allow for as-needed chemical deliveries, with performance periods spanning multiple years and the ability to issue task orders against the primary vehicles as specific needs arise.
