About this file
This attachment is an analyte list supporting a laboratory testing services solicitation issued by the County of Sacramento, Department of Waste Management and Recycling for groundwater quality testing. The document specifies comprehensive chemical and inorganic compound testing requirements across multiple EPA analytical methods, including EPA 8260 (volatile organic compounds), EPA 8270 (semi-volatile organic compounds), EPA 8151A (herbicides), EPA 8141B (organophosphate pesticides), and EPA 8080 (pesticides and PCBs). The analyte list establishes detection limits for purposes of reporting (DLRs) in accordance with California Code of Regulations, Title 22, Section 64400, Article 34, with specific DLR values provided for each analyte or noted as unavailable where applicable. The scope requires testing of over 100 volatile organic compounds, approximately 80 semi-volatile compounds, multiple pesticide and herbicide categories, and inorganic constituents including metals and general chemistry parameters. Unknown chromatographic peaks must be reported, flagged, and tracked for comparison to subsequent sampling events, with identification potentially required for recurring unknowns.
The analyte list reflects ongoing regulatory compliance requirements for groundwater monitoring and establishes the technical specifications that responsive laboratories must meet to qualify for this contract opportunity. The testing methodologies and detection limits are standardized and established under California regulations, indicating that proposals will be evaluated based on laboratory capability to perform these analyses consistently and accurately. The extended EPA 8260 list includes additional compounds beyond the standard EPA 8260B protocol, and similar extended testing requirements are specified for other analytical methods, suggesting comprehensive environmental assessment needs for the County's groundwater quality program.
