About NIGP 99231

NIGP 99231 Chemical Testing Services (Item) covers water quality and environmental compliance testing that state and local governments procure directly from laboratories to satisfy regulatory reporting obligations — not the broader laboratory testing taxonomy that includes medical, forensic, and materials-science work. Recent solicitations show state and local buyers purchasing certified water and wastewater analysis (drinking water compliance, PFAS testing, wastewater process control, biosolids residuals), environmental site characterization (groundwater monitoring, stormwater, deep injection well analysis), and specialized analyte work (equine drug testing, herbicide PFAS content evaluation, acute and chronic aquatic toxicity). The issuing-body mix spans municipal water and wastewater utilities (City of Holly Hill, City of Palm Bay, City of Sarasota, City of Tallahassee), county governments and special districts (Hillsborough County Public Schools, Hillsborough County Board of County Commissioners, Sarasota County, Sacramento County, Gwinnett County), state environmental and agriculture agencies (Illinois Racing Board, Illinois Department of Agriculture, Texas Department of Criminal Justice), and county parks departments (Boulder County). Hillsborough County Public Schools appears twice in the recent cycle, issuing two separate ITBs for water and wastewater laboratory services within six weeks.

Florida dominates the recent-opportunity volume, with five solicitations posted between June and October 2026 — Sarasota County (IFB 262894RM for water, wastewater, stormwater, and solid waste testing, bids due August 21), City of Sarasota (ITB 26-13JS for analytical laboratory services, bids due June 2), City of Palm Bay (ITB 50-ITB-26 for laboratory testing and professional services with estimated historical annual spending of $65,665–$95,438, bids due October 6), Hillsborough County Public Schools (ITB 26311-ITB-MST and ITB 26311A-ITB-MST for water and wastewater services, bids due August 18 and September 24 respectively, both under SBEP preference), and Hillsborough County Board of County Commissioners (ITB-26-00323 for acute and chronic toxicity testing, estimated contract value $460,350.00 over three years, bids due July 31). Beyond Florida, activity includes Gwinnett County, Georgia (BL089-26 comprehensive materials and field testing on an annual contract, bids due August 3), Sacramento County, California (RFP 2026GEN0045 for groundwater quality monitoring at three landfill facilities, proposals due May 26), Illinois Racing Board (RFQ 27-002 for equine laboratory testing services for state fairs, August 1–September 30 contract period, quotes due July 17), Illinois Department of Agriculture (horse testing at racing events, proposals due June 11), Volusia County, Florida (RSQ 26-SQ-111IF for professional construction material testing services, FEMA-funded, deadline August 20), Texas Department of Criminal Justice (solicitation 696-IG-26-P034 for laboratory testing services across nine classifications, proposals due May 13), and Boulder County, Colorado (RFI for PFAS evaluation methodologies on herbicides, responses due May 15). Mandatory qualifications across these solicitations include state environmental laboratory accreditation (Florida NELAP/NELAC, FDOH ELCP, California State Water Resources Control Board accreditation, ISO/IEC 17025 for equine and competition animal testing), EPA method compliance, and proof of appropriate insurance, with some procurements requiring rapid turnaround (five to ten working days for final reports) and sample courier services included in vendor pricing.
