The contract aims to ensure ongoing environmental compliance and water quality monitoring by engaging a professional lab capable of delivering reliable, timely, and technically sound toxicity assessments. Proposals must be submitted by September 3, 2026, and should demonstrate expertise in regulatory-standard testing methods and the ability to respond promptly to unexpected findings requiring further investigation or mitigation strategies. All services are to be performed in California, and the City anticipates ongoing collaboration with the selected proponent to address water quality concerns across municipal systems. The primary point of contact for all inquiries is Rajvir Sahota, reachable via email or phone, and responses must be submitted through the designated public procurement portal. While no set-aside provisions are specified, the solicitation is open to all qualified laboratories meeting the City’s technical and operational requirements, with evaluation based on demonstrated capability, experience, and proposed methodology.
