UNSPSC 81151902: Geophysical exploration

UNSPSC 81151902 Geophysical exploration is a Commodity code that encompasses groundwater and aquifer assessment, characterization, and monitoring services solicited by state water agencies, counties, and municipalities to support water supply planning, resource management, and permit compliance. Recent state and local opportunities show work spanning brackish aquifer production zone analysis using geophysical logs and subsurface mapping, groundwater monitoring and sampling at wellfields, professional hydrogeological and well services including aquifer performance testing and permit evaluations, and building envelope assessments involving infrared and electronic inspection technologies. Issuing bodies include state water development boards, county water resource divisions, and city/county facilities management offices. Texas and Florida account for the preponderance of recent activity, with the Texas Water Development Board, Volusia County, and Sarasota County all soliciting geophysical and hydrogeological expertise within the past four months.

The Texas Water Development Board posted RFP 58027RFP0003 on July 6, 2026, requesting proposals for brackish groundwater production zone analysis across fourteen Central Texas counties (Carrizo-Wilcox, Queen City, Sparta, and Yegua aquifers), due August 6, 2026, with contract work through August 31, 2027 and renewal options through 2030; respondents must demonstrate ten years of hydrogeology experience, three years with geophysical log documentation and GIS subsurface mapping, and professional geoscientist licensure. Volusia County, Florida issued RSQ 26SQ65SR in April 2026 for professional hydrogeological and well services supporting its twenty-six production wells and nine water treatment facilities, with work including well evaluation, design, permitting, aquifer performance testing, and hydrogeological studies on a task-assignment basis under a three-year basic contract with two optional renewal periods. Sarasota County solicited quarterly and monthly groundwater monitoring and sampling services at the Carlton Memorial Reserve Wellfield through RPS on April 14, 2026, requiring Florida professional engineer or geologist licensure and $1,000,000 professional liability insurance on an initial three-year continuing services agreement. All three opportunities require professional licensing and insurance limits in the $1 to $2 million range, with emphasis on advanced technical qualifications, government contract experience, and demonstrated expertise in state-specific regulatory frameworks and aquifer systems.
