A model to predict the bacterial quality of a rangeland stream

Creator:: Biskie, Howard A
Abstract:: Grazing cattle usually have access to streams as a source of drinking water. A model was developed for the personal computer to predict the bacterial quality of these streams. The model estimates the number of organisms that enter the stream by the direct deposit of feces and by runoff from...

Potential of a fungus, Acremonium sp., to decolorize pulp mill effluent

Creator:: Lesley, Dawn
Abstract:: This project explored the feasibility of using fungi in a constructed wetland for the treatment of pulp mill effluent. The effluent is high in dissolved lignins (some of which are chlorinated), which have proven very difficult to degrade biologically. Mindful of work done with the (terrestrial) white rot fungi, especially...

Decomposition of cattail and bulrush plant parts in a constructed wetland treating pulp mill effluent

Creator:: Walz, Anita
Abstract:: Dried cattail and bulrush plant pieces in mesh bags were incubated in the constructed wetland treating Pope & Talbot pulp mill effluent. Two ponds planted with each species and two depth ranges in each pond were chosen, to determine decomposition rates. Bags were withdrawn and analyzed at five time points...

Bacteria die-off in stream sediments

Creator:: Sherer, Brett Micheal
Abstract:: The purpose of this study was to evaluate the impact sediment has on the survival of bacteria in a typical rangeland stream. This information is an important component in determining a time integrated prediction of bacterial numbers in the stream sediment and overlying water. Bacterial survival in stream is a...

Flow characteristics of constructed wetlands : tracer studies of the hydraulic regime

Creator:: Stairs, Darrin B.
Abstract:: Treatment efficiency in a constructed wetland is related in part to the amount of time that a wastewater remains in the system. Current design methods idealize the system as a plug flow reactor and use a "residence time" based solely on the volume of the cell and the flow rate....

An ammonia stripping and recovery system for animal wastewaters

Creator:: Crown, Julia K.
Abstract:: Traditionally, livestock operations were small and combined with cropping operations. This allowed farms to be self-sustaining because nutrients were constantly recycled on the farm. Since the Haber-Bosch chemical process was patented, crop farmers turn to industrial fertilizers when soils nutrients are depleted. Animal and plant operations diverged, functionally separated, and...

Constructed wetland treatment of fecal coliform in dairy pasture runoff

Creator:: Osborn, Erik C. J.
Abstract:: A constructed wetland receiving pasture runoff from a dairy in Tillamook, OR was monitored during the winter of 1997-98 in order to estimate coliform treatment efficiency during winter high flow periods. Monitoring occurred during four sampling periods, each lasting 2 to 4 days. Samples were taken every two hours from...

Source identification of fecal pollution in the Tillamook watershed : antibiotic discriminant analysis

Creator:: Bower, Robert J.
Abstract:: The identification of sources of point and nonpoint fecal pollution is difficult to determine. Understanding the sources of fecal organisms in quality limited waters could greatly enhance our ability to restore and protect the water quality and habitat of these systems. Antibiotic resistance patterns of fecal streptococci bacteria were analyzed...

Transport and transformations of nitrogen compounds in effluent from sand filter-septic system draintile fields

Creator:: Bushman, Jennifer L.
Abstract:: A total of 44 intermittent sand filter-septic systems, in five counties of Western Oregon, were sampled over a three-month period during the summer of 1995. The sand filter systems varied in age from 36 months up to 167 months (3 to 13.9 years). Liquid samples were taken from the septic...
