UNSPSC 77141700: Soil or sludge or solid waste testing

Testing of soil, sludge, solid waste or material by a NELAC / VELAP certified laboratory using EPA approved methods.

UNSPSC 77141700 Soil or sludge or solid waste testing, a Class code, encompasses environmental site assessment, waste characterization, and contamination testing services that state and local governments procure to support remediation projects, facility operations, and compliance with environmental regulations. Recent solicitations show state and local agencies are actively buying soil and sludge testing integrated into larger environmental remediation scopes—such as site investigation, waste profiling, and disposal certification—rather than as standalone testing services. The issuing bodies include state environmental departments, county environmental divisions, municipalities, university systems, and special-purpose districts operating across Texas, Georgia, Nevada, Oregon, and Florida. Testing services typically form part of broader hazardous materials management contracts where contractors must characterize contaminants (VOCs, SVOCs, PCBs, inorganic constituents, and regulated petroleum products), validate disposal pathways, and generate manifests and certificates of destruction or disposal. Vendors in this space compete on technical capability, regulatory compliance expertise, turnaround time for lab analysis, and integrated project delivery across characterization and removal phases.

Representative recent opportunities include the Texas Commission on Environmental Quality's RFQ for Superfund Engineering Services (posted June 15, 2026, due June 8 with the pre-proposal conference held May 5), which requires comprehensive site surveys and field sampling activities at Texas Superfund sites with professional engineers and qualified personnel; the Nevada Division of Environmental Protection's RFP for Environmental Mitigation, Assessment, and Remediation Services (posted July 7, 2026, due August 11), covering waste characterization and removal across four service categories statewide on an as-needed basis with anticipated start January 1, 2027; and the City of Atlanta's multi-step sealed bid for environmental remediation at the Chattahoochee Brick Company site (posted July 2, 2026, with questions due July 31), encompassing excavation and off-site disposal of approximately 5,700 tons of lead- and cadmium-contaminated surface soils plus potential removal of PCB-laden subsurface soils under EPA Brownfields Cleanup Grant funding with a $2.23 million estimated value. Testing and characterization appear most active in states with significant environmental remediation programs and industrial legacy sites—Texas, Georgia, and Nevada show the densest recent procurement activity—with strong demand from county environmental departments and state-level environmental protection divisions managing Superfund, brownfields, and voluntary remediation programs.
