UNSPSC 70131506: Soil improvement

UNSPSC 70131506 Soil improvement is a Commodity code covering soil sampling, testing, analysis, and site-specific remediation work that state and local governments procure for agricultural land management, environmental compliance, construction support, and facility planning. Recent state and local solicitations under this code span soil sampling for nutrient analysis on state-managed agricultural leases, geotechnical investigation and laboratory testing for construction projects, soil fumigation services at state nurseries, and soil sourcing and testing for landfill operations. The issuing-body mix includes state departments of natural resources and agriculture, county utilities and port authorities, cities, and special-purpose districts; repeat buyers include the Illinois Department of Natural Resources (soil sampling across agricultural leases), the Missouri Department of Conservation (soil fumigation), and multiple Georgia and Florida municipalities (geotechnical testing for infrastructure projects).

Recent activity concentrates in Illinois, Missouri, Georgia, and Florida. The Illinois Department of Natural Resources posted soil sampling and laboratory analysis across five geographic regions covering approximately 10,000–11,000 acres and 2,900–3,300 sampling points on state-managed recreational areas, fish and wildlife areas, and state parks, with bids due October 21, 2026 under solicitation 27422DNRDIRECB54580. The Missouri Department of Conservation solicited soil fumigation services at the George O. White State Nursery in Licking, Missouri (approximately 14 acres using methyl bromide and chloropicrin injection), with bids due July 10, 2026 under IFB MDC 0000000226SL. Georgia and Florida municipalities have posted multiple geotechnical testing RFPs and RFQs for construction material testing supporting water and wastewater infrastructure, parks, streets, and drainage projects—including the City of Augusta geotechnical testing RFP (proposals due September 11, 2026 under RFP 26-176) and Volusia County professional construction material testing RSQ (deadline August 20, 2026 under 26-SQ-111IF). Maryland Environmental Service solicited sourcing, testing, and delivery of up to 450,000 cubic yards of cover soil to Brown Station Road Sanitary Landfill in Prince George's County, with bids due July 15, 2026.
