WA ELAP accredited laboratory to analyze river samples for E. coli bacteria

The Washington State Department of Ecology is seeking a WA ELAP‑accredited laboratory to perform E. coli analysis on river water samples for a one‑year environmental monitoring program, with an optional second year. The lab must be located within a one‑hour drive of Union Gap or Goldendale, WA, and must deliver both traditional laboratory reports and an electronic CSV data file for each sampling month. The project involves roughly 702 samples (approximately 27 per week) collected over 26 weeks, with sampling occurring two or three days per week (Monday‑Thursday). The contractor must adhere to specific quality‑assurance procedures, including method blanks and analytical duplicates, and must submit results within 30 days after each month’s sampling period. • WA ELAP accreditation required (NA‑MUG membrane filtration or Colilert Quanti‑Tray method). • Sample handling: analysis must begin within 24 hours of collection; labs must accept samples Mon‑Fri 08:00‑17:00 with after‑hours drop‑off possible. • Deliverables: electronic laboratory report and CSV data file; both due within 30 days after each month’s sampling. • Budget ceiling: $50,000 (excluding travel and sales tax); pricing is per‑sample for the total 702 samples. • Contract period: October 1 2026 – September 30 2027 (optional extension to September 30 2028).
