The Environmental Protection Agency (EPA) intends to award a firm-fixed price contract for the purchase of two Lumex RA-915M Mercury Vapor Analyzers, which will replace two aging models currently in use. This procurement is essential for conducting emergency responses and ensuring compliance with health and safety regulations, as the analyzers are designed to detect extremely low concentrations of mercury vapor in ambient air, providing critical data for safe clean-up operations. The sole source contract will be awarded to Ohio Lumex Co, Inc., as they are the only manufacturer in the U.S. capable of providing the necessary equipment and support. Interested parties may direct inquiries to Contract Specialist Daniel Garcia Flores at garciaflores.daniel@epa.gov, with the procurement utilizing Simplified Acquisition Procedures under the threshold of $250,000.
