UNSPSC 77101902: Industrial waste site investigation

UNSPSC 77101902 Industrial waste site investigation is a Commodity code covering potentially responsible party searches, chain of title research, site contamination assessments, and associated environmental site characterization work solicited by state environmental agencies and county governments. State and local procurement offices use this code when they need to identify liable parties for contamination cleanup, understand property ownership chains, evaluate PFAS or other contaminant presence in materials or facilities, and support remediation operations at contaminated sites. The California Department of Toxic Substances Control (DTSC) emerges as a repeat buyer under this code, soliciting PRP and title search services, SCADA system support for active superfund remediation, and environmental evaluation methodologies. County environmental and parks departments also post opportunities here when assessing contamination in acquired herbicides or requiring site investigation support.

Recent activity concentrates in California and Colorado. The California Department of Toxic Substances Control posted RFP# 2627-07 on July 9, 2026, requesting proposals for PRP searches, chain of title searches, and reporting services with an estimated contract value not exceeding $950,000 over two years; proposals are due August 13, 2026, with a 5% California small business preference and a waived 3% DVBE participation requirement (though voluntary DVBE participation receives incentive consideration). The same department issued a Request for Information on March 26, 2026, regarding SCADA system support services for the Stringfellow Superfund Site, with responses due April 9, 2026. Boulder County Parks and Open Space in Colorado posted an RFI on May 4, 2026, seeking vendor capabilities to evaluate whether herbicides contain PFAS or PFOS, with responses due May 15, 2026; this was an exploratory procurement not committing to contract award. The geographic footprint beyond California and Colorado shows limited recent activity in the available records, suggesting the code sees heaviest use in Western states with active environmental remediation programs or state environmental agencies managing contaminated sites.
