| Description | During 2009-10, North Creek was assessed for toxicity due to lead and copper. The Gig Harbor Sportsman’s Club is the known source of lead to the creek. Bioassay tests concluded that North Creek is not acutely toxic. High concentrations of dissolved organic carbon in the creek are likely buffering acute toxicity from metals. Analysis of periphyton showed that the periphyton community in North Creek is impacted downstream of the Sportsman’s Club. Dissolved lead concentrations measured in North Creek below the Sportsman’s Club were extremely elevated, while dissolved copper concentrations were relatively low both upstream and downstream of the Sportsman’s Club. |
