NIGP 92685: Soil, Soil Vapor, and Groundwater Sampling and Analysis (Including Disposal)

NIGP 92685 Soil, Soil Vapor, and Groundwater Sampling and Analysis (Including Disposal), an Item code, covers on-call and project-specific environmental sampling, laboratory analysis, and site characterization work that state and local governments pursue for landfill operations, airport compliance, contaminated-site remediation, and infrastructure construction projects. The code encompasses groundwater and soil monitoring at closed municipal solid waste landfills; methane gas well sampling and statistical trending; phase I and phase II environmental site assessments; asbestos and lead-based paint surveys; NPDES permitting support; wetland determinations; petroleum storage tank assessments; stormwater pollution prevention planning; and materials testing services at water treatment plants and hospital construction sites. Issuing bodies span county purchasing departments (Henry County, Georgia; Orange County, California), municipal governments (City of Plant City, Orlando, Bradenton, and Union City), state environmental protection agencies (New Jersey DEP, Texas Commission on Environmental Quality, California EPA Office of Environmental Health Hazard Assessment), airport authorities (Broward County Aviation Department), university systems (UCLA), and transit or special-purpose districts. Henry County, Georgia appears as a repeat buyer, issuing separate RFPs and RFQs in 2026 for groundwater and methane monitoring at closed landfills and for on-call materials and field testing services under GDOT prequalification requirements.

Representative recent solicitations include Henry County's RFP 27-09 (due September 10, 2026) for groundwater and methane gas monitoring services at two closed municipal solid waste landfills, evaluated 95% on technical qualifications and experience with only 5% weight on cost; Broward County Aviation Department's RFP PNC2131299P1 (due October 30, 2026) for environmental planning and consulting services at Fort Lauderdale-Hollywood and North Perry Airports, anticipated to exceed $500 million with evaluation weighted 45% on past performance, 30% on personnel ability, 20% on project approach, and 5% on pricing; and the City of Bradenton's continuing-services RFQ for environmental testing engineering (due April 2, 2026) with individual task orders capped at $500,000 and construction costs not exceeding $7.5 million per project. Activity concentrates in Florida, Georgia, California, Texas, and New Jersey, with additional opportunities in Oregon, Illinois, Massachusetts, and Minnesota. Cost proposals typically receive minimal weight (5% or less) in evaluation scoring, with emphasis on technical qualifications, staff experience, past performance on similar projects at commercial or municipal facilities, ASTM and regulatory compliance capabilities, and insurance and safety certifications including OSHA compliance, HAZWOPER training, and professional liability coverage.
