UNSPSC 81151903: Geophysical photo interpretation

UNSPSC 81151903 Geophysical photo interpretation (Commodity) spans groundwater resource assessment, aquifer characterization, and hydrogeological analysis work that state and local water agencies procure to support water supply planning, permit compliance, and subsurface resource evaluation. The work being solicited under this code centers on geophysical log interpretation, subsurface mapping using GIS and statistical modeling, and aquifer production-zone delineation — applied to groundwater feasibility studies, well-field evaluations, and water resource inventory projects. Issuing bodies include state water development boards, county water resource and utilities divisions, and municipal water authorities. The mix skews heavily toward specialized technical work performed by licensed professional geoscientists and hydrogeologists, often paired with project management, stakeholder engagement, and regulatory compliance requirements. Professional licensure (Professional Geoscientist, Professional Geologist, or Professional Engineer in the relevant state) is a standard qualification floor.

Recent activity concentrates in Texas and Florida. The Texas Water Development Board posted RFP 58027RFP0003 on July 6, 2026 (proposals due August 6, 2026) for brackish groundwater production zone analysis across the Carrizo-Wilcox, Queen City, Sparta, and Yegua aquifers in fourteen Central Texas counties — requiring ten years of hydrogeology experience in the project area, three years with geophysical log documentation, three years in GIS subsurface mapping, and professional geoscientist licensure; the contract runs through August 31, 2027 with renewal options through August 31, 2030. In Florida, Volusia County issued RSQ 26SQ65SR (due April 9, 2026) seeking professional hydrogeological and well services including geophysical and television survey evaluations, aquifer performance testing, and groundwater modeling for twenty-six production wells and nine water treatment facilities; the contract is structured as a three-year base with two one-year renewal options, evaluated 25 percent on experience (with a five-year minimum requirement) and 25 percent on firm and employee qualifications. Sarasota County, Florida also solicited groundwater monitoring and sampling services through RPS (due April 9, 2026) at Carlton Memorial Reserve Wellfield with quarterly and monthly well sampling under a three-year CCNA Non-Library Continuing Services Agreement. Recent activity outside these two states and the specific geophysical and hydrogeological focus includes unrelated water infrastructure and facilities management procurements; the code shows limited documented activity volume.
