Attch. 23 LAB SAMPLING QTY.xlsx

This is a laboratory sampling and analysis requirements document for the Southbay Wastewater Treatment Plant (SBIWTP) Operations and Maintenance contract. The document specifies comprehensive water quality testing protocols across multiple sampling streams, including influent, effluent, stormwater, biosolids, transboundary flows, and wet weather events, with detailed frequency schedules and analytical methods.

The sampling requirements are organized by water stream category and testing frequency. Influent and effluent sampling require 365 annual samples for standard parameters such as biochemical oxygen demand, chemical oxygen demand, pH, suspended solids, and turbidity using Standard Methods (SM) and EPA protocols. Both streams require 52 annual samples for metals analysis via ICP EPA 200.7 and 12 annual samples for nutrient analyses including ammonia, nitrate, and phosphate. Specialized testing occurs quarterly (4 samples annually) for dioxin, pesticides, and semivolatile organics. Stormwater analysis includes 4 annual samples across similar parameters. Biosolids testing requires 12 monthly samples for metals analysis using EPA 6010B and STLC extraction methods, plus daily pH and total solids measurements (365 samples annually). Transboundary flows and wet weather sampling at the Canyon Collector require 20 samples annually each for comprehensive analysis including dioxin, asbestos, pesticides, metals, and microbial indicators. Primary and secondary effluent sampling mirrors influent/effluent protocols with 365 daily samples for routine parameters, 52 samples for metals and extractable materials, and 12 quarterly samples for nutrients and microbial testing. All analyses reference specific EPA and Standard Methods protocols with indicated turnaround times, primarily 5-day analysis windows.
