A descriptive analysis of the waterways in Coos Bay Oregon on the basis of general, ruminant and human Bacteroides-Prevotella 16S rDNA markers

Creator:: Jones, Thomas E., Jr.
Abstract:: We explain a new method of detecting non point source fecal contamination using a PCR based method called Touchdown Polymerase Chain Reaction (TD-PCR). Using genetic markers particular to general, ruminant and human Bacteroides- Prevotella genes, we identified presence in both fresh and salt water environments. Water samples from four sites...

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 Oregon's beach sites and assessing twenty-six coastal beach areas for recreational water quality standards

Creator:: Benedict, Rae T.
Abstract:: With congressional passage of the BEACH Act in October of 2000, Coastal and Great Lakes states were mandated to assess coastal recreation waters for the application of ambient water quality standards. This research encompasses two components involved in applying the BEACH Act statues to Oregon. The first component was to...

Quantifying the impacts of riparian cattle grazing at Soap Creek Ranch near Corvallis, Oregon

Creator:: McArthur, Cynthia
Abstract:: A documented case history of riparian grazing at Oregon State University's Soap Creek Ranch was conducted from 1999 to 2001. Impacts of four different riparian grazing treatments were evaluated. Emphasis was placed on investigating the relationship between riparian cattle use and water quality. Through a series of carefully designed and...

Novel Experimental Designs and Mathematical Models to Study Fecal Indicator Bacteria Persistence in Surface Water

Creator:: Brooks, Lauren
Abstract:: High counts of fecal indicators, used to signal the potential presence of pathogens associated with untreated waste, result in the classification of water bodies throughout the United States as impaired. Nonpoint sources of unknown origin that contribute to fecal contamination make management of impaired waters challenging, as they are difficult...

Fecal Bacteroidetes host distributions and environmental source tracking

Creator:: Dick, Linda K.
Abstract:: Contamination of recreational and shellfish waters with fecal pollution is a major water quality issue with associated economic impacts and human health risks. Reliable fecal source identification and rapid, quantitative analyses are essential components of risk assessment. Enteric bacteria that are endemic to specific hosts have a potential role as...

Analysis of Bacteroidales 16S rRNA gene sequences from a geographically isolated human population

Creator:: Petersen, Carolyn A.
Abstract:: Standard methods of measuring fecal pollution in water do not distinguish between human and non-human sources. Molecular technology enabled the development of host-specific markers that distinguish fecal sources. Human specific PCR primers, HF183F and HF134F, were designed based on phylogenetic analyses of partial 16S rRNA gene sequences from the Bacteroidales...

Solar disinfection of drinking water : Effectiveness in peri-urban households in Siddhipur Village, Kathmandu Valley, Nepal

Creator:: Rainey, Rochelle C.
Abstract:: The study examined pH, turbidity, and fecal contamination of drinking water from household water storage containers, wells and taps, and the Godawari River, and tested the effectiveness of solar disinfection (SODIS) in reducing levels of fecal contamination from household containers. Second, the study investigated the relationship between use of SODIS...

Migration of E. coli and solutes to tile drains via preferential and matrix flow

Creator:: Moreno, Daniel
Abstract:: The extent of agricultural drainage has created concern for its potential undesirable effects on surface water quality. Land applications of liquid manure on tile drain fields have the potential to transport solutes and bacteria to the drains following precipitation or irrigation events and many times are directly sent to a...
