District Context & Mission Impact
This major water treatment chemical supply contract is administered by the U.S. Army Corps of Engineers Baltimore District. The Baltimore District operates critical civil public works infrastructure, including the Washington Aqueduct, which provides safe drinking water to approximately one million citizens across Washington, D.C., Arlington County, and Fairfax County, Virginia. Aluminum sulfate (alum) and polyaluminum chloride (PAC) serve as essential primary inorganic coagulants during municipal water clarification. These chemicals bind suspended particles, organic matter, and turbidity in raw water sources, allowing contaminants to settle rapidly during sedimentation and filtration phases. Securing long-term chemical procurement vehicles guarantees continuous drinking water processing and federal environmental compliance through 2031.
