UNSPSC 81151910: Airborne geophysical acquisition

Airborne geophysical acquisition is a process of measuring the variation of several key physical or geochemical parameters of the earth. The most important parameters measured are conductivity, magnetic susceptibility, rock density, radioactive element concentration, and reflectance spectra.

UNSPSC 81151910 Airborne geophysical acquisition (Commodity) is being solicited by state water agencies and county environmental divisions for groundwater characterization, aquifer analysis, monitoring well sampling, and hydrogeological assessment work — though the recent opportunities show limited direct procurement under this code and instead reflect work that involves geophysical data collection and analysis as a component of broader groundwater and water-quality programs. The Texas Water Development Board and Texas Higher Education Coordinating Board (THECB), Sarasota County, Volusia County, the City of DeBary, and Broward County represent the issuing bodies in the recent record, spanning water resource management, higher education, and facilities administration. The code appears to capture geophysical surveys, well evaluations, aquifer performance testing, and data collection that underpin water supply planning and resource assessment, though many of the opportunities in the record address professional hydrogeological services, monitoring, and facility management rather than acquisition of airborne geophysical surveys specifically.

Recent activity concentrates in Texas and Florida. The Texas Water Development Board is seeking proposals for brackish groundwater production zone analysis across fourteen central Texas counties (Atascosa, Bastrop, Bexar, Caldwell, DeWitt, Fayette, Gonzales, Guadalupe, Karnes, Lavaca, Lee, Live Oak, Williamson, and Wilson) under RFP 58027RFP0003, with responses due August 6, 2026 and contract start September 1, 2026; the scope requires ten years of project management, technology transfer, and hydrogeology experience in the project area, with professional geoscientist licensure required and a Subcontracting Plan demonstrating good faith effort to utilize VetHUB vendors. Volusia County issued an RSQ for professional hydrogeological and well services (Solicitation 26SQ65SR, due April 9, 2026) addressing well evaluation, design, and remedial development for twenty-six production wells and nine water treatment facilities. Sarasota County solicited groundwater monitoring and sampling services at the Carlton Memorial Reserve Wellfield (RPS, due April 9, 2026) requiring quarterly and monthly well sampling over three years. The record shows no dedicated procurement under this code as a standalone airborne survey service; the code may see limited recent state and local activity or may be tagged inconsistently against water resource consulting and hydrogeological assessment work.
