Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Two strategic approaches to water quality control in Oregon's Willamette River are presently being utilized: point source treatment and flow augmentation. Dry weather releases from reservoirs are for authorized purposes other than water quality. Reservoirs can participate in pollution control by summer flow augmentation where authorized water resource objectives (flood control, navigation, etc.) are not sacrificed. It is hypothesized that the differences in total energy impact between treatment and augmentation may be substantial. Of additional interest is the comparison between direct utilization of energy for Willamette Valley pollution control and the indirect energy requirements of such programs. Input/Output analysis (I/O) provides an econometric methodology to study direct and indirect energy response to pollution control alternatives. An energy I/O national model is coupled with a comprehensive Willamette River dissolved oxygen model. Discharge and loadings are empirically related to surveyed direct dollar and energy expenses. These costs are then transformed by I/O to total energy costs. Three approaches to environmental control for the Willamette are examined. One is that of current enforcement coupled with present levels of augmentation. Another consists of less augmentation and increased wastewater treatment. Appropriate tactics involve advanced secondary methods of treatment, regionalization of treatment plants, and yet more stringent effluent requirements for industry. The third approach consists of increased flow augmentation for water quality control. Corresponding treatment is somewhat relaxed. Each alternative of environmental control is evaluated as if it had been practiced in a study year of low natural runoff. The relation of augmentation for water quality to other river uses is used to value flow in a benefits-foregone manner. Independently, reservoir costs are allocated to water quality. An instream unit price is thus assigned to augmentation. For each alternative of treatment and augmentation, the dissolved oxygen quality of the Willamette is simulated and the costs of the environmental strategy estimated. River quality, dollar cost, and energy impact response surfaces are developed. Indirect energy costs, largely expended out of the region, are roughly twice the direct energy use. Because of the predominance of treatment expenses over augmentation cost and the energy-intensive nature of treatment, energy impact is substantially a reflection of treatment degree. Because augmentation reduces treatment environmentally required, energy and dollar efficient management calls for the full role of augmentation in water quality control. To a reasonable degree this has in fact been carried out. Policies of the region are compared; the present commitments to environmental improvement and economic development are found to contradict the area's energy objectives.
