Abstract:
Selected Elements and Organic Chemicals in Bed Sediment and Fish Tissue of the Tualatin River Basin, Oregon, 1992-96.Denny Road). Concentrations of total chlordane, dieldrin, and p,p'-DDE in sediment at these sites exceeded USEPA Tier 2 screening values. Concentrations of total chlordane in fish tissue exceeded both the National Academy of Science/National Academy of Engineering (NAS/NAE) guidelines and the New York State criteria. Organochlorine concentrations were much lower downstream of these sites where the land use changed to light industrial; concentrations of trace elements, however, increased. The most contaminated bed sediment found in this study was collected from the most urban site (Beaverton Creek at Cedar Hills Boulevard). USEPA sediment screening values were exceeded for four organochlorine pesticides, six polyaromatic PAHs, two phthalates, p-cresol, and eight metals (including arsenic, cadmium, lead, and mercury). Levels of polychlorinated biphenyls in the few fish found at this site exceeded the NAS/NAE guidelines for fish tissue. The objectives of this study were to assess the occurrence and magnitude of trace element and selected organic contaminants in streams of the Tualatin River Basin, to compare contaminant levels found in Tualatin River Basin streams with published guidelines for the protection of aquatic life, to place the contaminant levels found in the Tualatin River Basin streams in context, regionally and nationally, by comparing them with those found in the Willamette Basin and by the USGS National Water Quality Assessment (NAWGA) Program, to compare contaminant concentrations in bed sediment with those in fish tissue, and to identify contaminant patterns that would help managers make decisions regarding future monitoring and the implementation of pollution prevention and abatement programs. The area of study was the Tualatin River Basin. Bed sediment samples were collected from 15 sites in the Tualatin Basin; fish tissue samples were collected at 9 sites. Many of the sampled streams drain largely urban areas that include a mixture of commercial and residential land. Chicken, Dairy, and McKay Creeks are the only sampled streams with appreciable agricultural land in their basins that do not also have significant urban influences. Gales Creek drains mostly forested land and is minimally affected by anthropogenic inputs; it represents background concentrations. At wadeable sites, the top 1-2 cm of fine grained sediment was collected with a Teflon scoop. Sediment was removed from several depositional areas within a reach and composited. At nonwadeable sites (Tualatin River above Dairy Creek, and Tualatin River at Elsner Road), the same approach was used, except that the method was applied to sediment sections that had been obtained using an Eckman dredge. In all cases, about 8 L of wet sediment was collected from each site. The reach length sampled varied among sites from about 40 to 1,200 feet. Sediment samples destined for organics analysis were sieved through a 2-mm stainless steel sieve to remove twigs, pebbles, and other debris. Samples destined for elemental analysis were sieved through a 63 micromillimeter nylon screen to remove the sand fraction as well as a larger debris. Because trace elements are not expected to significantly sorb to the sand-sized fraction, sieving at 63 micromillimeters effectively "normalizes" samples to the size fraction having the largest fraction of trace elements. Samples were kept at 4 degrees Centigrade until analysis. The sediment collection and preparation method is described in detail by Shelton and Capel (1994). Fish were collected by electrofishing and then euthanized by a sharp blow to the head. Each sample contained 4-20 whole fish. All fish were sculpin. Samples destined for elemental analysis were placed in resealable polyethylene freezer bags; samples destined for organics analysis were wrapped in aluminum foil. All samples were frozen until analysis. The fish were thawed, homogenized, subsampled by the USGS Water Quality Laboratory. Sediment samples were analyzed for major and minor elements, organochlorine pesticides, pesticide metabolites, PCBs, and semivolatile organic compounds such as PAHs, phthalates, and phenols. Fish tissue samples were analyzed for major and minor elements, organochlorine pesticides, pesticide metabolites, and PCBs. The chemical analyses and analytical methods are summarized in table 2 of Bernadine Bonn, Selected Elements and Organic Chemicals in Bed Sediment and Fish Tissue of the Tualatin River Basin, Oregon, 1992-1996. In addition, for sediment samples, organic carbon content and fraction of grain size less than 63 micrometers were determined; for fish samples, lipid content and moisture content were determined. All analyses were performed by the USGS. Elemental analyses of sediment were done by the Geologic Division Laboratory (Lakewood, Colorado); sediment size fraction analyses were done by the laboratory at the Cascades Volcano Observatory (Vancouver, Washington); all other analyses were done by the National Water Quality Laboratory.

Attribute_Accuracy:
Attribute_Accuracy_Report:
Censored semiquantitative data - nondetection of an analyte in a sample does not indicate that the concentration of the analyte in the sample equalled zero. The smaller the concentration of analyte in a sample, the greater the chance that it will not be detected even if it is present. Different types of statistics were used to communicate the analytical limits of different methods. A minimum reporting level (MRL) was used for elements, organochlorine pesticides, and PCBs. Data for these analytes are censored at the MRL; that is, concentrations less than the MRL are reported as nondetections. When the concentration is greater than ro equal to the MRL, the sample is assumed to be reliably different from a blank sample. When the analyte is not detected in the sample, the concentration is assumed to be less than the MRL. MRLs are based on a variety of factors, including method performance and analyst judgement. More about data accuracy is given in Bonn, 1999. Bed sediment samples were collected from 15 sites in the Tualatin Basin; fish tissue samples were collected at 9 sites.
