The U.S. Army Corps of Engineers Baltimore District awarded a single-award Indefinite Delivery Contract (IDC) to Earth Science Laboratories Inc., a self-certified small disadvantaged business, for the purchase of chelated copper algaecide. The IDC, valued at $545,737.50, allows the agency to issue delivery orders for the specialized chemical product over a period of 5 years through August 2026. The purpose of the contract is to provide the Corps with a mechanism to obtain algaecide that meets ANSI/AWWA and NSF/ANSI standards for potable water treatment and infrastructure maintenance, particularly at the Washington Aqueduct Dalecarlia Water Treatment Plant in Washington, D.C. Delivery orders issued under the IDC to date, totaling over $350,000, have been for firm-fixed-price purchases of the algaecide, with no set-asides utilized. Earth Science Laboratories has a history of providing water treatment solutions to the Corps, including previous awards for zebra mussel mitigation systems. The original solicitation, a pre-solicitation notice, indicated that the Corps was seeking qualified sources capable of providing chelated copper algaecide services for the Washington Aqueduct. The procurement was structured as a 100% small business set-aside under NAICS code 325180 for other basic inorganic chemical manufacturing. The period of performance was specified as 5 years from the date of award, with deliveries of the algaecide to be made to the Washington Aqueduct Dalecarlia Water Treatment Plant in Washington, D.C.
