  Citation × Citation Citation Abstract Copy Title: Selected elements and organic chemicals in bed sediment and fish tissue of the Tualatin River Basin, Oregon, 1992-96 Author: Bonn, Bernadine A., Washington County (Or.). Unified Sewerage Agency., Geological Survey (U.S.) The U.S. Geological Survey (USGS) has worked cooperative with the Unified Sewerage Agency of Washington County (USA) since 1990 to assess water quality in the Tualatin River Basin. 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; compare contaminant levels found in Tualatin River Basin streams with published guidelines for the protection of aquatic life; 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 (NAWQA) Program; compare contaminant concentrations in bed sediment with those in fish tissue; and identify contaminant patterns that would help managers make decisions regarding future monitoring and the implementation of pollution prevention and abatement programs.

  Citation × Citation Citation Abstract Copy Title: Urban residents and non-point source pollution : an examination of practices, influences, and values in the Tualatin watershed Author: Nielson, Lisa M. In July of 2001, the Environmental Protection Agency (EPA) activated the Total Maximum Daily Load (TMDLs) provisions of the Clean Water Act. As the first river in Oregon to implement TMDL regulations, people and agencies in the Tualatin basin face many challenges. Non-point source pollution affects water quality in the Tualatin River and comes from various sources. This research focuses on urban home and yard maintenance practices. During 2002, I examined Best Management Practices (BMPs) that have been established for urban residents by water quality and conservation agencies. Employing a range of qualitative and quantitative methods, factors surrounding agency BMP adoption and agency goals for urban residential practices are investigated. Observation of actual home and yard maintenance styles are correlated with residents' explanation of maintenance styles and residents' expression of environmental and other values. In-depth interview and content analysis of websites and pamphlets show agency preferences which push for: low input lawns and yards, a realization of the environmental impacts of individual maintenance styles, and recognition of benefits of clean water to humans and the environment. Results from a survey of residents (n=98), direct observation (n= 183), and short interviews (n=22) suggest the presence of behaviors harmful to water quality and conservation efforts. Harmful behaviors appear to be supported by the importance of neighborhood appearance, a desire to protect property values, and a tendency to want to balance economic considerations and environmental consequences. Although agency goals include behavioral and value change, the lack of concern for environmental impact of maintenance styles in the survey population suggests the need for alternative educational efforts. A focus on non-environmental benefits of low input yard designs and maintenance that also promote neighborhood beauty will be key to the reduction of urban residential non-point source pollution in the Tualatin watershed.
