The anthropogenic introduction of nutrients to water bodies has been shown to alter the structure and function of natural aquatic ecosystems, yet national EPA lake and reservoir nutrient criteria remain too broad for effective regional water quality management. This study uses a reference site approach to propose numeric nutrient criteria...
A study of phosphorus loading and water quality implications was conducted for
the Oregon coastal lakes. The study was based on existing data for lake total phosphorus
concentrations and for watershed land uses. A phosphorus mass-balance model was
developed to predict lake total phosphorus concentrations from estimated phosphorus
loading from...

Poor quality water or an inadequate supply of water can take the pleasure from country living. Problems with quantity or quality of domestic water occur all over Oregon.
This dissertation consists of three papers on land use economics and regulation. The first paper focuses on the environmental impacts of land use and their implications for the design on water quality trading policies. The second and third papers address local land use regulations and their impact on land values...
Contamination of drinking water occurs despite strict regulations, yet few studies
have been conducted to assess the public's perception of risk about drinking water.
The purpose of this study was to assess risk perception associated with drinking water
supplied by small water systems and to determine alternative measures that people...
Many municipalities throughout western Oregon rely upon forested watersheds as a source for domestic water supply. These watersheds are commonly managed by state or
federal agencies or private corporations for timber production. Activities related to forest management within municipal watersheds have the potential to adversely affect water quality. Timber harvesting...
