Field Service Contract for Total Organic Carbon (TOC) Analyzer, IAD

The Metropolitan Washington Airports Authority is pursuing a sole-source award to HACH Company under solicitation REQ-26-25851 for a field service contract at Washington Dulles International Airport. The contract provides for comprehensive preventive maintenance, diagnostic support, calibration, software support, and repair services for the proprietary HACH BioTector 7000i Total Organic Carbon (TOC) Analyzer. This specialized service is required to ensure continuous, reliable operation and maintain compliance with the Clean Water Act and the National Pollutant Discharge Elimination System (NPDES) program for stormwater quality reporting. The estimated contract value is 102,556.13 dollars, with a performance structure consisting of three base years and two option years. Due to the proprietary nature of the equipment, only HACH factory-trained personnel are authorized to perform the work, as the use of unauthorized service providers would void the equipment warranty. The procurement is justified as a sole-source acquisition because HACH maintains exclusive control over the technical specifications and service authorization for the analyzer. The solicitation was posted on August 14, 2026, with a response deadline of August 29, 2026.
