NIGP 92630: Contaminated Soil Services

NIGP 92630 Contaminated Soil Services is an Item code encompassing hydrogeologic consulting, Superfund remediation engineering, underground storage tank response, environmental site assessments, and field sampling at contaminated sites across state departments, counties, cities, and special-purpose water utilities. State and local governments procure these services to investigate soil and groundwater contamination, design and oversee remedial action, manage regulatory compliance with EPA and state environmental agencies, and support cleanup of brownfields, Superfund sites, and UST releases. Recent solicitations show work spanning feasibility studies, remedial design, remedial action oversight, Phase I and II environmental site assessments, groundwater treatment plant operations, and expert witness testimony.

Issuing bodies include state environmental agencies (Texas Commission on Environmental Quality), county utilities departments (Pinellas County Utilities), cities (Bradenton, Union City, Dallas, Long Beach, Sacramento), and state land-protection programs (Georgia). Pinellas County Utilities has posted multiple professional services RFQs in this space (hydrogeologic consulting for aquifer storage and recovery, vertical utility projects for water and wastewater infrastructure). The Texas Commission on Environmental Quality issued an RFQ for five-year Superfund engineering services requiring Project Engineers, Project Managers, Resident Project Representatives, and Groundwater Treatment Plant Operators with Texas professional engineering licenses, due June 8, 2026. The City of Bradenton solicited environmental testing engineering services through an RFQ with an April 2, 2026 deadline, and the City of Dallas issued a Job Order Contracting RFCSP for asbestos removal, mold remediation, lead abatement, and industrial waste services with proposals due April 24, 2026, establishing a 30 percent Small Business Enterprise aspirational utilization goal and a maximum aggregate contract amount of $15 million across awarded contractors. Geographic activity concentrates in Florida (Pinellas County, Bradenton, Long Beach), Texas (TCEQ statewide, Dallas), California (Sacramento, Santa Clara), and Georgia (statewide UST response). Set-asides and preferences vary by issuing body—Pinellas County requires 10 percent SBE subconsultant commitments on work assignments over $50,000; Dallas applies its DRIVE policy with SBE participation scoring; Texas TCEQ mandates HUB Subcontracting Plans for Historically Underutilized Businesses; and Sacramento County offers local business and micro-business preferences.
