Proposed Purpose and Location of Field Areas: Distribution studies of two native freshwater mussel species, Anondonta californiensis and Margaratifera falcata, were conducted along the South Fork of the Eel river by Jeanette Howard (1). We plan to observe these locations on May 22, 2007 to develop a field deployment protocol for future bioaccumulation studies involving A. californiensis (see Future Research and Collection Plans). Additionally, we plan to collect five bivalve individuals to gain familiarity with this species in preparation for a larger field test. We have obtained a scientific collection permit through the Department of Fish and Game. Housing needed: One night stay for two researchers (May 21) Affected species: Anondonta californiensis Number to be collected: 5 Future Research and Collection Plans: We have conducted laboratory bioaccumulation tests with the nonnative freshwater bivalve species (Corbicula fluminea) in order to limit the collection of A. californiensis. A field biological test, requiring the deployment of native species to the Silver Creek and Coyote Creek ecosystems, is scheduled for the summer of 2007 (pending final permitting). A. californiensis was previously identified in the headwaters of Coyote Creek, but field exploration indicates that this organism is unlikely to be found currently in the local watershed. For this deployment we plan to transfer a limited number of A. californiensis from the Eel river location to Silver Creek to assess the ecological impacts of a stream flow augmentation project. Full Research Project Description: Freshwater mussels will be collected from the South Fork of the Eel River for use in perfluorochemical bioaccumulation studies. These studies are part of a larger project to evaluate the biological effects of water reuse for sustainable urban ecosystem restoration. This project focuses on residual, water soluble, organic compounds commonly found in wastewater treatment plant effluent. As part of the biological work, we will try to make connections between observed chemical concentrations in recycled water and toxicological effects. Collected mussels will be used for 28-56 day bioaccumulation studies in which uptake of perfluorochemicals from recycled water will be assessed. (1) Howard, J. K.; Cuffey, K. M.
