The table below shows how many times laboratory results have shown high levels of bacteria at each monitgoring site in Green Cove Creek. sites with more frequent high results may be closer to bacteria sources.
A result is considered high if over 320 Most Probable Number (MPN), the number set by the Washington Department of Ecology. Sites with average E. coli levels above this number are highlighted in red. Sites with average
E. coli levels above 100 MPN are over the ideal protective level set by the State of Washington. They are highlighted in orange.
The average concentration of bacteria means these sites are generally not safe for direct contact with the water. Bacteria can enter your body through the nose and mouth as well as through cuts and scrapes on the skin. We recommend you don't play in, wade barefoot or in sandals, or touch the water in Green Cove Creek.
