IFB 25-E0032 Water Sampling Services

The Office of Environmental Health Hazard Assessment (OEHHA) of the California Environmental Protection Agency is seeking a qualified contractor to collect contamination‑controlled, high‑volume tap‑water samples for micro‑plastics analysis at nine state‑owned facilities. The work includes providing all sampling equipment, performing strict clean‑room handling, maintaining chain‑of‑custody records, and shipping samples to a designated analytical laboratory. Deliverables are phased: a kickoff meeting agenda, a detailed sampling plan (to be approved before field work), and a final field‑operations report covering all sites. The contract is fixed‑price, limited to $49,999, and requires the contractor to have at least three years of micro‑plastics analytical experience and two years of QA/QC experience, as well as appropriate insurance and a valid California business license. • Perform high‑volume in‑line filtration and grab‑sample collection at nine California sites, totaling ~162 collections. • Implement contamination‑control procedures (HEPA‑filtered laminar flow hood, triple‑wash glass containers, daily air‑blank monitoring, chain‑of‑custody documentation). • Submit a sampling plan by 31 Aug 2026, complete field sampling by 31 Jan 2027, and provide all required reports and documentation. • Meet strict eligibility criteria (micro‑plastics lab experience, QA/QC background, good standing with the California Secretary of State, insurance coverage).
