Intent to Award - NTN Site CO01

The U.S. Geological Survey (USGS) Office of Acquisitions and Grants has issued a Sole Source Intent to Award notice for the operation of a National Atmospheric Deposition Program/National Trends Network (NADP/NTN) precipitation monitoring station at Site CO01 in Bent County, Colorado. This Special Notice indicates the USGS's intent to award a firm-fixed-price contract to Sonora Servaes for atmospheric deposition station operation services. The contract falls under NAICS code 541990 (All Other Professional, Scientific, and Technical Services) and is designated as a Total Small Business set-aside. The notice was posted on March 26, 2026, and the due date for vendor responses is March 30, 2026.

The primary objective of this contract is to maintain continuous precipitation and atmospheric deposition monitoring at the site through weekly sample collection, processing, and shipment, along with routine instrument maintenance and data transmission. The contractor must perform all laboratory work in compliance with USGS Operations Manuals and coordinate directly with the Wisconsin State Laboratory of Hygiene regarding site specifications and performance monitoring. The contract structure includes a 12-month base period with four optional 12-month renewal periods. Eligible vendors who believe they can provide equivalent services must contact Contract Specialist Jonathan Wyatt at jwyatt@ios.doi.gov by 12:00 PM EST on March 31, 2026, to challenge the sole source justification. The USGS justified the sole source award based on restricted site access on Colorado state-owned land and the need to maintain an existing long-standing research relationship with the land-owning and sponsoring organization.
