Table Legend

Cell Color Fecal Coliform Value Concern Level Individual day <= 200 CFU/100 ml Low Concern - safe for swimming Individual day > 200 & <= 1000 CFU/100 ml Moderate Concern – still safe for swimming Individual day > 1000 CFU/100 ml

or geometric mean > 200 CFU/100 ml High Concern – flagged for resample. For more information see Beach Closure Protocol – Fecal coliform bacteria

Cell Color Bacteria Value Concern Level Individual day <= 200 CFU/100 ml Low Concern - safe for swimming Individual day > 200 & <= 1000 CFU/100 ml Moderate Concern – still safe for swimming Individual day > 1000 CFU/100 ml

or geometric mean > 200 CFU/100 ml High Concern – probable closure. For more information see Beach Closure Protocol

NOTE: Beach closure and reopening decisions are made by Public Health – Seattle & King County. Decisions are based on these results plus additional information about beach conditions, and may not always match the concern levels shown here.
