Preliminary investigation of microbial indicators in the assessment of Oregon streams

Creator:: Campbell, Heidi M. K.
Abstract:: The Environmental Monitoring and Assessment Program (EMAP) site selection protocol was used to generate a random sample of streams throughout the state of Oregon. One hundred and forty-six selected streams were sampled during the summer, low-flow period of 1997. Traditional microbial public health indicators, including heterotrophic plate counts (HPC), total...

Evaluating microbial indicators of environmental condition in Oregon rivers

Creator:: Pennington, Alan Travis
Abstract:: Traditional public health bacterial indicators of water quality and the Biolog® system were evaluated to compare their response to other indicators of stream condition with the state of Oregon and between ecoregions (Coast Range, Willamette Valley, Cascades, and Eastern Oregon). Forty-three randomly selected Oregon rivers were sampled during the summer...

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...

Investigation of the presence and change over time of water quality parameters in selected natural swimming areas in Oregon

Creator:: Van Ess, Erica
Abstract:: Few studies, and none in Oregon, have examined the presence and change of water quality parameters over time in popular natural swimming areas. This information is necessary to better understand water quality and risk of illness from either fecal contamination or cross-infection from other swimmers. The purpose of this study...

Evaluating benthic macroinvertebrates as bio-indicators of freshwater habitat quality in an eastern Oregon agro-ecosystem

Creator:: Scherr, Melissa A.
Abstract:: The effect of anthropogenic disturbance on river systems is gaining attention, and concerns about the state of freshwater natural resources are increasing globally, as are efforts to restore habitat that has been degraded by disturbance. In rivers, non-point source pollution affects the physical characteristics of the habitat and the endemic...

Respiratory strategies and associated exchange epithelia as determinants on contaminant uptake in aquatic insects

Creator:: Buchwalter, David B.
Abstract:: Aquatic insects are used extensively to evaluate water quality. Despite their widespread use as indicator organisms, relatively little is known about the organismal characteristics that determine sensitivity differences to individual and multiple stressors. Insects have evolved several respiratory strategies that range from breathing atmospheric air to utilizing dissolved oxygen in...

Temperature and infiltration characterization of a constructed wetland for wastewater treatment

Creator:: Gregory, Christopher T.
Abstract:: The City of Woodburn, Oregon's Wastewater Treatment Plant (WWTP) has been investigating several natural alternatives for improving effluent quality. Based on its current National Pollution Discharge Elimination System (NPDES) permit, the WWTP will require additional reduction of temperature and ammonia levels in the summer, especially in the critical month of...
