• 1. [Article] Major-ion, nutrient, and trace-element concentrations in the Steamboat Creek Basin, Oregon, 1996

  This report presents the concentrations of major ions, nutrients, and trace elements in water and bottom sediments collected in the four-tributaries during the low-flow condition of September 9-13, 1996. ...

Forest Service, Geological Survey (U.S.) This report presents the concentrations of major ions, nutrients, and trace elements in water and bottom sediments collected in the four-tributaries during the low-flow condition of September 9-13, 1996. Stream-water chemistry results are contrasted, and trace-element concentrations compared with U.S. Environmental Protection Agency chronic aquatic life toxicity criteria. Bottom -sediment trace-element results also are constrasted and compared with concentrations considered to be enriched in streams of the nearby Willamette River Basin and to interim Canadian threshold effect level (TEL) concentrations established for the protection of aquatic life.

• 2. [Article] Inorganic chemistry of water and bed sediment in selected tributaries of the South Umpqua River, Oregon, 1998

  This report presents results of an investigation of water and streambed-sediment quality in selected tributaries of the South Umpqua River. Concentrations of inorganic constituents in water (major and ...

  Citation × Citation Citation Abstract Copy Title: Inorganic chemistry of water and bed sediment in selected tributaries of the South Umpqua River, Oregon, 1998 Author: Hinkle, Stephen R., Geological Survey (U.S.) This report presents results of an investigation of water and streambed-sediment quality in selected tributaries of the South Umpqua River. Concentrations of inorganic constituents in water (major and minor ions, nutrients, and trace elements) and streambed sediment (primarily trace elements), along with standard field parameters, are tabulated for samples collected at 10 sites. Aqueous trace-element concentrations are compared with U.S. Environmental Protection Agency (USEPA) criterion continuous concentrations for the protection of aquatic life. Streambed-sediment trace-element concentrations are compared with Canadian sediment quality guidelines for the protection of aquatic life and, to provide a frame of reference, with previously collected streambed-sediment data from the Willamette Basin in western Oregon.
