Port of Seattle BOD Study

Location: SeaTac, WA
Owner: Port of Seattle

OCI has been conducting a Biological Oxygen Demand (BOD) study at the Seattle‐Tacoma International Airport with the goal of identifying sources of BOD to the sanitary sewer system (SSS) and providing recommended corrective actions. Project tasks include field sampling of the SSS and analysis of lab results. The project has several complexities, a few of which include manhole locations within the AOA and on the Ramp areas, requiring direct coordination with Port staff, and completing the sampling within a 4-hour window. A sampling event requires visiting up to 21 separate manholes, collecting samples according to the sampling plan, which includes photos, video, and notes to record the conditions at the time of the sample. Following a documented chain of custody, OCI delivers samples to a third-party lab where they are tested for BOD, Glycol, and Fats, Oils, and Grease (FOG). The lab results, analysis, and recommendation from each testing event are documented in an annual report.
