UNSPSC 71121203: Core preservation services

Services to keep the core in the same state as when it was brought to the surface.

UNSPSC 71121203 Core preservation services (Commodity) encompasses water well drilling, completion, maintenance, testing, abandonment, and related subsurface infrastructure work that state and local governments procure to develop, repair, rehabilitate, and decommission potable water supplies and monitoring systems. The work spans drilling new production and irrigation wells to specified depths with pump and electrical installations; rehabilitating existing wells through video surveys, casing repairs, and system upgrades; plugging and abandoning orphan oil and gas wells under federal Infrastructure Investment and Jobs Act funding; and performing emergency repairs and preventive maintenance on distributed well networks across parks, utilities, and industrial sites. Issuing bodies include state environmental and energy agencies (Michigan Department of Environment, Great Lakes, and Energy; Mississippi Oil and Gas Board; Illinois Department of Natural Resources), municipal water departments and utilities (City of Albany, Georgia; City of Wrens, Georgia; City of Reynolds, Georgia; Hillsborough County and Seminole County, Florida), county special districts and park authorities (Boulder County Parks and Open Space; Escambia County Waste Services; Sarasota County; City of Ocala), and standalone park and recreation departments. Michigan and Florida show concentrated recent activity, with Michigan's EGLE running multiple orphan well plugging solicitations and Florida counties issuing well maintenance, repair, and monitoring contracts; recent opportunities also appear in Georgia, Mississippi, Illinois, Colorado, Texas, and Oregon.

Representative recent opportunities include the Michigan Department of Environment, Great Lakes, and Energy's prequalification for oil and gas well plugging services (RFP 7612600000025221, proposals due September 22, 2026), which established a five-year vendor pool across four equally weighted technical criteria for abandoned-well abandonment work on Michigan's Lower Peninsula; the City of Albany, Georgia well rehabilitation solicitation (Bid Ref. 27-032 Well No. 21, ITB due November 16, 2026) seeking sealed bids for comprehensive assessment, repair, and testing of a municipal water well; and the Mississippi Oil and Gas Board's orphan well plugging and reclamation contract (IFB RFx No. 3160008162, bids due December 18, 2026) covering nine wells in Jasper and Jones Counties under federal Build America, Buy America Act and Davis-Bacon prevailing wage requirements. Hillsborough County, Florida issued two solicitations for specialized on-site services: an ITB for two-year water well maintenance and repair across 67 irrigation and potable wells ($688,073 estimated value, due June 12, 2026) and a sole-source notice for Wet Well Wizard aeration system installation and maintenance ($5.371 million over five years to Agora Water Solutions LLC, restricted to proprietary equipment compatibility). Set-asides and preferences appear selectively—Illinois Department of Natural Resources designated a small-business set-aside for the Union County SFWA well repair project (IFB due July 9, 2026), and Michigan EGLE considers service-disabled veteran-owned business status during evaluation. Work is predominantly firm-fixed-price, turnkey, or time-and-materials task-order contracting, often funded through state revolving loan programs, federal infrastructure grants, or county capital budgets, with Davis-Bacon prevailing wage requirements appearing in federally funded orphan well projects.
