Factors affecting risk perception about drinking water and response to public notification

Creator:: Anadu, Edith Chijioke
Abstract:: 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...

Essays on land use regulation

Creator:: Hascic, Ivan
Abstract:: 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...

Geographic variations in water quality and recreational use along the upper Wallowa River and selected tributaries

Creator:: McDowell, Theodore R.
Abstract:: Physical, chemical and bacterial water quality parameters of the upper Wallowa River were sampled periodically between July 2, 1978 and June 9, 1979 at nine stream and lake sampling sites. Water upstream from Wallowa Lake was typified by low nutrient concentrations ( generally below detectable limits except for nitrates), low....

Analysis of streamflow variability in Oregon for regional water quality monitoring programs

Creator:: Saligoe-Simmel, Julia L.
Abstract:: Streamflow variability can provide valuable information for nonpoint source pollution monitoring program planning. The research papers presented in this thesis examine selected properties of streamflow variability in Oregon to advance its application in regional planning of water quality monitoring programs. The products of this research depict Oregon streams by their...

Market water transfers as a water quality policy : a case study of the Malheur River Basin, Oregon

Creator:: Connor, Jeffery D.
Abstract:: Agronomic research documents a strong correlation between the level of irrigation water applied and the level of farm chemicals leached into water bodies. Consequently, policies that cause farmers to alter irrigation water management practices are likely to influence water quality. Water markets are a potentially attractive method of addressing agriculturally...

Analysis of Oregon's Domestic Well Testing Act data for use in a sentinel surveillance system for private well contaminants

Creator:: Hoppe, Brenda O.
Abstract:: The Safe Drinking Water Act ensures that public systems provide water that meets health standards. However, no such protection exists for millions of Americans who obtain water from private wells. Concern for safety is warranted as most wells draw from underground aquifers, and studies demonstrate that groundwater is affected by...

Evaluation of bacterial community indicators of stream sanitary and ecological condition

Creator:: Bracken, Caragwen L.
Abstract:: The focus of this research was to develop bacterial community indicators of stream sanitary and ecological condition. The first study compared substrate utilization patterns between centrifuged and uncentrifuged split samples. We found a shift in the relative proportion of each group of bacteria following centrifugation, with a marked increased in...

Residents' attitudes toward water resource protection in metropolitan Portland, Oregon

Creator:: Larson, Kelli L., 1975-
Abstract:: Three research questions are addressed in this study: (1) To what degree do residents support/oppose various aspects of water resources protection? (2) What factors explain residents' attitudes? and, (3) How do attitudes vary between participants and nonparticipants of place-based groups (watershed councils and neighborhood associations)? The population of interest is...

Fecal coliform bacteria in stream sediments : sampling methodology, measurement and modeling the impact on stream water quality

Creator:: Church, Wendy S.
Abstract:: Three studies were conducted related to the measurement and impact of stream sediment fecal coliform (FC) bacteria on stream water quality. In part one an enumeration technique for sediment FC was defined and statistically characterized. This characterization necessitated the development of a sample splitting mechanism, which was found to split...

Economic analysis of restoration practices to improve water quality and fish habitat of a large river floodplain : a case study of the Willamette River, Oregon

Creator:: Seedang, Saichon
Abstract:: In- stream water temperature is one of the most important environmental factors associated with the decline in salmonid populations and their habitats in the Pacific Northwest. Most ecological restoration practices that attempt to reduce instream temperatures center on replanting or reestablishing riparian vegetation and increasing flows. However, in a large...
