UNSPSC 77101901: Industrial site investigation

UNSPSC 77101901 Industrial site investigation is a Commodity code covering environmental and property assessment work that state and local governments solicit to investigate contaminated sites, evaluate environmental conditions, and establish property ownership and liability history. The work ranges from potentially responsible party (PRP) searches and chain of title investigations to Phase I environmental assessments and chemical contamination screening. Issuing bodies include state environmental agencies, county governments, municipalities, and special-purpose districts. The California Department of Toxic Substances Control, Town of Stonington, Connecticut, and Boulder County Parks and Open Space represent the mix of state environmental departments, small municipalities, and county jurisdictions pursuing this category of services.

Recent activity spans California, Connecticut, and Colorado. The California Department of Toxic Substances Control issued RFP# 2627-07 on July 9, 2026 (proposals due August 13, 2026) for PRP and chain of title searches with an estimated contract value not exceeding $950,000 over two years, anticipating approximately 20 PRP and 20 title search reports annually. The Town of Stonington, Connecticut released RFP 2026-003ston on May 5, 2026 (due June 23, 2026) for a Phase I environmental assessment of the Campbell Grain Property, with no specified budget or contract term disclosed. Boulder County Parks and Open Space in Colorado issued RFI RFI28426 on May 4, 2026 (due May 15, 2026) to evaluate methodologies and vendor capabilities for PFAS and PFOS screening in herbicide formulations — a non-binding information-gathering activity with no commitment to award a contract. The California solicitation applies a 5% small business preference and DVBE incentive consideration; Connecticut and Colorado RFPs do not specify set-asides in the available documentation.
