UNSPSC 71171900: Formation water testing services

Includes range of services involved in monitoring formation water elements in oil and gas production.

UNSPSC 71171900 Formation water testing services, a Class code, addresses laboratory and field testing of subsurface water samples to assess quality, composition, and suitability for regulatory compliance, resource management, and environmental monitoring. State and local governments procure these services primarily to support water resource management, environmental remediation, and compliance with state and federal water-quality standards. Testing typically covers salinity, contamination levels, microbial content, and chemical composition in formation water — water present in geological formations, often extracted during oil and gas operations, mining, or encountered during well drilling and groundwater investigations.

The source provides no recent opportunities under this code. State and local procurement activity in formation water testing services is not documented in the available recent solicitations, which limits visibility into the current issuing-body mix, geographic concentration, and active buying patterns in this specialty. Formation water testing is a niche procurement area, and opportunities may be concentrated among state environmental or natural-resource agencies rather than appearing in broad state or local solicitation databases.
