NIGP 92629: Contaminated Groundwater Services (Including Discharge Pipe Installation)

NIGP 92629 Contaminated Groundwater Services (Including Discharge Pipe Installation), an Item code, encompasses groundwater and surface water monitoring, remediation, laboratory testing, and water service infrastructure replacement work that state and local governments actively procure. Recent solicitations show municipalities and utility districts buying groundwater assessment and detection monitoring at closed landfills; methane gas monitoring and laboratory analysis at waste disposal sites; stream restoration and green infrastructure installation; oil spill containment and cleanup in post-disaster settings; and replacement of aging potable water service lines with compliant materials. Issuing bodies span utility commissions (Waterford Utility Commission in Connecticut, Pinellas County Utilities in Florida), county environmental and waste management departments (Henry County, Georgia; Sacramento County, California), municipal water authorities (Sacramento County Water Agency), special-purpose districts (Atlanta Beltline, Inc., Glades Electric Cooperative), and state environmental protection agencies (Nevada Division of Environmental Protection, Texas Commission on Environmental Quality). Henry County, Georgia appears as a repeat buyer, soliciting groundwater and methane gas monitoring annually at two closed landfills under RFPs 27-09 and 27-06.

Recent procurement activity concentrates in Georgia, Florida, Connecticut, and California, with additional activity in Nevada and Texas. Representative opportunities include Henry County's RFP for groundwater and methane gas monitoring services at West Asbury Road Phase II and Old Windy Hill landfills (RFP 27-09, proposals due September 10, 2026), with cost weighted at only 5 percent of the evaluation score; the Town of Waterford Utility Commission's IFB for replacement of plastic water service lines with copper tubing on Rope Ferry Road (IFB #26-014, bids due November 12, 2026, with 25 percent subcontractor set-aside for Connecticut DAS-certified small and minority-owned businesses); and the Sacramento County Department of Waste Management and Recycling's RFP for laboratory testing services supporting groundwater quality monitoring across three active landfills (proposals due May 26, 2026, with minimum three-year contract term and required California Water Resources Control Board accreditation). Glades Electric Cooperative in south-central Florida is soliciting a Master Services Agreement for oil spill cleanup and containment in post-disaster environments covering 2026–2027 (RFP 202609, proposals due August 28, 2026, time-and-materials compensation with FEMA compliance requirements). Prevailing wage requirements, site-specific permitting, insurance mandates, and local-vendor preferences appear consistently across opportunities in this code.
