UNSPSC 70171506: Ground or surface water modeling services

UNSPSC 70171506 Ground or surface water modeling services, a Commodity code, encompasses the testing, analysis, and monitoring services that state and local governments procure to assess and maintain water quality at treatment facilities, distribution systems, monitoring wells, and environmental compliance points. Recent solicitations reveal that issuing bodies are purchasing routine water quality testing, wastewater analysis with regulatory reporting, groundwater monitoring across landfill facilities and monitoring networks, laboratory analytical services for trace organics and priority pollutants, chlorine tank inspection and hydrostatic testing, and specialized hydrologic engineering analysis to support water system operations and infrastructure decisions. The code spans a mix of issuing bodies: state departments of corrections and environmental agencies, county water authorities and environmental finance authorities, city water departments and utilities commissions, transit authorities managing wastewater systems, and regional water environment services districts across multiple states.

Recent activity shows broad geographic distribution. Illinois Department of Corrections issued water testing solicitations for correctional facilities (Menard and Robinson centers) in June and July 2026; Georgia Environmental Finance Authority solicited a Clean Water Needs Survey in July 2026 on behalf of state and local governments; Texas Health and Human Services Commission sought wastewater analysis services for Mexia State Supported Living Center in July 2026; California jurisdictions (Sacramento County, Santa Cruz Water Department) posted laboratory testing and water loss control program design work in June and April 2026; and Florida counties and cities (Hillsborough, Broward, Orange, Palm Bay, Okaloosa) solicited chlorine tank inspection, SCADA upgrades, water reclamation facility improvements, and portable water quality monitoring equipment in May through July 2026. Representative solicitations include: Menard Correctional Center (Illinois Department of Corrections) RFQ for licensed water testing services with July 17, 2026 response deadline; Georgia Environmental Finance Authority RFQ for Clean Water Needs Survey with July 24, 2026 response deadline; Sacramento County Department of Waste Management and Recycling RFP for three-year laboratory testing services across landfill groundwater monitoring locations with May 26, 2026 response deadline; and City of Fort Worth RFQ for chlorine tank inspection and hydrostatic testing on an as-needed basis with February 24, 2026 response deadline. Activity under this code reflects steady demand across water quality compliance, environmental monitoring, and facility operations support, with most opportunities posted in the first half of 2026.
