UNSPSC 12161701: Ampholyte mixtures

UNSPSC 12161701 Ampholyte mixtures is a Commodity code that in practice captures laboratory testing services for water quality, wastewater compliance, and environmental monitoring rather than the sale of ampholyte chemical products themselves. State and local governments procure these services to meet regulatory obligations under the Clean Water Act, Safe Drinking Water Act, and state environmental protection rules. The issuing bodies are municipal water and wastewater utilities, typically through city public works or environmental departments. Vendors are certified analytical laboratories that must hold state environmental laboratory certifications, maintain NELAP accreditation, and perform work to EPA and state-approved methods at required detection limits. Scope includes routine analyses (pH, conductance, turbidity), standard contaminant screening (bacteria, nutrients, metals), and specialized testing (Cryptosporidium, Giardia) across water treatment, wastewater treatment, distribution systems, groundwater monitoring wells, and industrial pretreatment programs. Unit pricing varies widely—from zero for calculated field measurements to $425 per analysis for specialized tests—and annual spending ranges from tens of thousands to low hundreds of thousands of dollars per jurisdiction depending on facility count and sampling frequency.

The City of Palm Bay, Florida, issued Invitation to Bid 19-ITB-26 in April 2026 for comprehensive laboratory testing services supporting three wastewater treatment facilities, two water treatment facilities, groundwater monitoring, and industrial pretreatment compliance. The ITB required bidders to hold a minimum of five years of municipal water and wastewater experience, Florida Department of Health Environmental Laboratory Certification, and NELAP accreditation, with 75 percent of analytical work performed in-house and location within one hundred miles of the city. The bid deadline was March 17, 2026; three bids were received, ranging from $80,872 to $107,946 annually. The contract term is twelve months with four optional twelve-month renewals. Historical spending shows the city expended $66,360 in 2024 and $95,440 in 2025 on these services. No other recent state or local opportunities under this code are present in the source.
