| Abstract | Long Description |
North Creek is listed on the 2006 federal Clean Water Act Section 303(d) list for elevated concentrations of lead and copper. In 2008, the Washington State Department of Ecology (Ecology) conducted a study on North Creek that verified elevated concentrations of lead and copper. The Gig Harbor Sportsman′s Club has been identified as the likely source of lead to North Creek based on sampling efforts by the Tacoma-Pierce County Health Department in 2002 and by Ecology in 2008. This study will assess for potential adverse biological effects in North Creek due to elevated levels of lead and copper. Bioassay tests (daphnid and trout) and periphyton will be used to evaluate aquatic toxicity. Total and dissolved concentrations of lead and copper will also be measured in surface waters. Each study conducted by Ecology must have an approved Quality Assurance Project Plan. The plan describes the objectives of the study and the procedures to be followed to achieve those objectives. After completion of the study, a final report describing the study results will be posted to the Internet. |
