| Description | The Upper Columbia River (UCR) in northeast Washington State (WA) has been contaminated with mining and smelting wastes from a large smelter in Trail, British Columbia, Canada. Studies conducted over the past two decades have demonstrated the presence of toxic concentrations of metals associated with the smelter wastes in sediments, porewater, fish tissue, benthic macroinvertebrates and other media in the UCR and the downstream reservoir portion of the UCR, Lake Roosevelt, which is formed by Grand Coulee Dam. Surface water from Lake Roosevelt is diverted into Banks Lake and used as agricultural water supply throughout Eastern Washington. Previous surface water studies suggest metal concentrations in the water column met drinking water standards; however, these data are over 15 years old and updated baseline information is warranted. To ensure metal concentrations continue to meet Washington State’s water quality standards, concentrations of 13 priority metals and other water quality ancillary parameters (total dissolved solids, total suspended solids, alkalinity, hardness) will be measured at three sites over the course of two years. Samples will be collected seasonally to capture differences in flow regime and reservoir height and to provide an accurate estimate of metal concentrations in the water column over time. Results from this study will serve as updated baseline information for this waterbody and inform potential data gap information needs. | ||||
