The Department of the Army Corps of Engineers Engineering District Baltimore is seeking contractors to supply 75% phosphoric acid for the Washington Aqueduct's water treatment operations. The phosphoric acid will be used at two water treatment plants: Dalecarlia WTP and McMillan WTP. All supplied phosphoric acid must conform to ANSI/AWWA Standard B507 requirements in its latest revision and must be certified to meet NSF/ANSI Standard 60 for water treatment applications. The solicitation was posted on July 22, 2025, with proposals due by August 22, 2025. An update to the solicitation added a past performance worksheet and extended the question and answer period. The contract falls under NAICS code 325180 for Other Basic Inorganic Chemical Manufacturing and PSC code 6810 for Chemicals.
This procurement opportunity is designated as a Total Small Business set-aside, restricting competition to qualified small business concerns. The place of performance is located at 5900 MacArthur Blvd NW, Washington, DC 20016, which corresponds to the Washington Aqueduct facilities. The solicitation notice does not specify contract award values, quantities of phosphoric acid required, or identify any incumbent contractors. The procurement appears to be structured as a delivery order contract, suggesting it may involve multiple deliveries over a specified contract period. No timeline for service delivery or specific performance metrics beyond the chemical standards compliance were detailed in the available solicitation information.
