This data release contains bioassay data from sediment toxicity tests conducted by the USGS Columbia Environmental Research Center (CERC) with 66 sediment samples collected from in and around the Upper Columbia River in the fall of 2013. Toxicity testing was conducted from fall 2013 through summer 2014 with the amphipod, Hyalella azteca, the midge Chironomus dilutus, and the mussel Lampsilis siliquoidea. Short-term toxicity endpoints (10-28 d) included survival, weight, and biomass of all test organisms. Long-term tests with amphipods (42 d) and midges (about 50 d) included reproduction endpoint. These data are intended to be used to characterize concentration-response relationships between metals concentrations...

This data release contains chemistry and toxicity data from sediment toxicity tests conducted by the USGS Columbia Environmental Research Center (CERC) with 66 sediment samples collected from in and around the Upper Columbia River in the fall of 2013. Toxicity testing was conducted from fall 2013 through summer 2014 with the amphipod, Hyalella azteca, the midge Chironomus dilutus, and the mussel Lampsilis siliquoidea. Short-term toxicity endpoints (10-28 d) included survival, weight, and biomass of all test organisms. Long-term tests with amphipods (42 d) and midges (about 50 d) included reproduction endpoint. Sediments were analyzed for physical and chemical characteristics, including particle size distribution,...

Federal investments in ecosystem restoration projects protect Federal trusts, ensure public health and safety, and preserve and enhance essential ecosystem services. These investments also generate business activity and create jobs. The Economic Impacts of Ecosystem Restoration project aims to increase the availability of information on the costs and activities associated with ecosystem restoration, and to gauge the economic effects of these investments to local economies. This website provides case studies of Department of Interior (DOI) restoration projects associated with Natural Resource Damage Assessment and Restoration (NRDAR) cases, and Bureau of Land Management (BLM), Fish and Wildlife Service (FWS), and...

This data release contains physical and chemical data from an evaluation of metal contaminated sediments and pore water conducted by the USGS Columbia Environmental Research Center (CERC) with 66 sediment samples collected from in and around the Upper Columbia River in the fall of 2013. Sediments were analyzed for physical and chemical characteristics, including particle size distribution, total organic carbon, acid volatile sulfide, slag content, and concentrations of metals in total-recoverable and simultaneously-extracted fractions. Porewaters were separated by centrifugation and by peepers (diffusion samplers) and were analyzed for filterable metals, dissolved organic carbon, and major ions. These data are intended...
