Polydyne Inc.

Polydyne Inc. is a specialty chemical manufacturer based in Riceboro, Georgia, that has been registered to receive federal contract and grant awards since April 2002. The company specializes in the production of anionic and cationic polymers, which are critical chemical additives used in water and wastewater treatment processes to facilitate the separation of solids from liquids, improve treatment efficiency, and support infrastructure operations across federal installations. As a for-profit manufacturer of goods, Polydyne has established itself as a reliable and qualified supplier of polymer chemicals to defense and civilian federal agencies, with a demonstrated track record of delivering specialized products that support critical water infrastructure and environmental management programs, particularly within the National Capital Region.

Polydyne Inc. has received multiple firm fixed-price delivery orders from federal agencies totaling approximately $1.4 million in aggregate contract value across the period from 2021 through August 2025. The company's primary customers have been the U.S. Army Corps of Engineers, specifically the Baltimore District and the Washington Aqueduct operations, and the U.S. Marine Corps, with additional work performed for the International Boundary and Water Commission U.S.-Mexico. The company has supplied residuals dewatering polymer, cationic polymers, and anionic polymers in various forms to support water purification, wastewater treatment, sludge dewatering, and environmental management processes at federal installations including the Washington Aqueduct in Washington, D.C., Marine Corps Base Quantico in Virginia, and the Nogales Wastewater Treatment Plant in Rio Rico, Arizona. All delivery orders have been awarded as firm fixed-price contracts with no set-aside designations applied, though many have been issued under parent indefinite delivery vehicles that do carry small business set-aside designations. The delivery orders have ranged in value from approximately $2,500 to $324,000, with typical orders ranging between $12,000 and $250,000, and Polydyne has consistently performed as the prime contractor without identified subcontractors on these awards.

Polydyne Inc. currently holds five active Indefinite Delivery Contracts with federal agencies, with a combined ceiling value exceeding $7.2 million and performance periods extending through 2030. The most recently awarded contract, issued by the U.S. Army Corps of Engineers Baltimore District on August 14, 2025, is a single-award Total Small Business set-aside IDC valued at $1.935 million through August 2030 for the supply of residuals dewatering polymer, specifically polyacrylamide in liquid emulsion form, to support the Dalecarlia water treatment plant operated by the Washington Aqueduct, with an anticipated annual requirement of 270,000 pounds neat. A second Army Corps of Engineers contract, awarded September 8, 2023, is a single-award IDC valued at $469,200 through September 2026 for cationic polymer supply to the Washington Aqueduct, under which multiple year-based delivery orders have been issued. The U.S. Marine Corps has awarded Polydyne a single-award Total Small Business set-aside IDC valued at $310,000 with a performance period through June 2026 for the supply of anionic and cationic polymers to support operations at various Marine Corps installations. Additionally, the International Boundary and Water Commission U.S.-Mexico has awarded Polydyne two single-award Total Small Business set-aside IDCs, each valued at approximately $2.08 to $2.38 million with performance periods through 2026 and 2029 respectively, for the supply and delivery of polymer chemicals to the Nogales Wastewater Treatment Plant in Rio Rico, Arizona. These indefinite delivery vehicles demonstrate Polydyne's established position as a qualified and preferred supplier of water treatment chemicals to multiple federal agencies and reflect the company's capability to consistently deliver specialized polymer products that meet federal technical standards and operational requirements across diverse water infrastructure programs.
