| Abstract | Long Description |
Each study conducted by the Washington State Department of Ecology (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. Ecology will measure total mercury and methylmercury in surface water samples in three streams in, and adjacent to, the Lake Ozette watershed: Palmquist Creek, Umbrella Creek, and an unnamed reference creek. Sampling will occur monthly from September 2009 through March 2010. The goal of the study is to determine concentrations and fluxes of total mercury and methylmercury in streams draining different land uses. Palmquist and Umbrella Creeks flow into Lake Ozette′s north end; their drainage areas have undergone extensive logging. The unnamed reference stream is located in an adjacent watershed which has remained relatively pristine. Measurements of total organic carbon (TOC), dissolved organic carbon (DOC), total suspended solids (TSS), pH, dissolved oxygen, specific conductivity, and temperature will also be collected during each sampling event. |
