Passive Gas Sampling in Sewers

The U.S. Geological Survey, operating under the Department of the Interior, is conducting a market survey to identify qualified vendors capable of providing passive gas samplers for deployment in sanitary sewers and subsequent analysis of volatile organic compounds. The primary objective is to detect trichloroethene (TCE) and its degradation products in sewer systems to support environmental investigations by the U.S. Environmental Protection Agency. Contractors must demonstrate capability to provide self-contained, easily deployable passive sampler devices specifically configured for high-humidity sewer environments, with analytical results delivered within 40 days of sample receipt. The samplers must be capable of detecting six target compounds at specific laboratory limits of detection using EPA method TO-17, and must include tabular summaries and level IV data packages in the deliverables. This is a sources sought notice rather than a formal solicitation, and submissions are voluntary; however, interested firms must submit capability statements, recent relevant performance history, and size status documentation by January 16, 2026, at 5:00 pm MST via email.

This opportunity is designated exclusively for small businesses under NAICS code 541380, with a small business size standard of $19 million, including Indian Small Business Economic Enterprises, SBA-certified HubZone firms, 8(a) program participants, Service-Disabled Veteran-Owned small businesses, and other eligible small business categories. No incumbent contractor is identified in this sources sought notice, and no specific contract award value or budget range has been disclosed at this stage of the market survey process. The timeline for this market research phase extends to the January 16, 2026 deadline, after which the USGS will evaluate the capability statements and market feedback to determine procurement strategy for the upcoming formal solicitation. Potential awardees should note that all costs associated with responding to this sources sought notice are the contractor's responsibility, and selection for this survey does not guarantee participation in any subsequent procurement action.
