A Survey Of Source And Finished Water Supplies For Giardia Cysts And Cryptosporidium Oocysts, Lisa Martin Sexton
A Survey Of Source And Finished Water Supplies For Giardia Cysts And Cryptosporidium Oocysts, Lisa Martin Sexton
KWRRI Research Reports
The occurrence of Giardia lamblia cysts and Cryptosporidium parvum oocysts was determined from source and treated drinking water supplies at selected water treatment facilities in Eastern Kentucky. Giardia and Cryptosporidium are two human protozoan parasites often found in water supplies due to fecal contamination. Characteristic cysts and oocysts were identified from large volume water samples, typically 100 gallons for raw samples and 1,000 gallons for finished water, using an indirect fluorescent antibody specific for Giardia and Cryptosporidium. Source water from four different water treatment facilities utilizing a reservoir, river, and two creeks were assayed. All sites exhibited Giardia lamblia …

The Pollution Effects Of Pleasure/Work Boat Sewage Discharges On Fecal Contamination Levels Of Waters In And Around Marinas And Other Places Where Boats Are Moored On The Eastern Shore Of Virginia, George H. Bangs
Community & Environmental Health Theses & Dissertations
Contamination of seafood harvested from and recreational areas of the Chesapeake Bay, its tributaries and the Atlantic coast inshore waters may cause health problems for people consuming the seafood or coming in contact with the waters by swimming, water skiing, or other water sports. These health problems include, but not limited to, dysentery, typhoid and hepatitis (Natchez, 1990). This is a preliminary study into the level of fecal pollution generated by sewage discharges from boats in marinas and other places where boats are moored on the Eastern Shore of Virginia. Sites selected for the study included; (I) marinas and other …

A Comparison Of Plotless Density Estimators Using Monte Carlo Simulation, Richard M. Engeman, Robert T. Sugihara, Larry F. Pank, William E. Dusenberry
United States Department of Agriculture Wildlife Services: Staff Publications
We conducted an extensive simulation study to compare the performance of a large group of plotless density estimators (PDEs) to obtain clarification of their relative performance in a diversity of sampling situations. The PDEs studied included well-known ones from the literature plus some extensions and modifications introduced here. The simulations cover 96 combinations of 6 spatial patterns, 4 sample sizes, and 4 population densities. We made comparisons within classes of similar estimators, and we indicate the best-performing PDEs out of the complete set studied. Over all spatial patterns, the angle-order estimator with measurements to the third closest individual in each …

Continuous Monitoring Of Volatile Organic Compounds In Air Emission Using Membrane Extraction Microtrap Gc System, Xin Zhang
Theses
A novel method for continuous monitoring volatile organic compounds (VOCs) in air at trace level is presented. A membrane module and a microtrap were used along with gas chromatographic analysis. The membrane module consisted of a bundle of silicone rubber hollow fibers and separated the VOCs from the gaseous stream. The microtrap which is a very small adsorbent trap played the roles of preconcentrator and injector. The VOCs selectively permeate across the membrane into a strip gas in the membrane module. Before entering the GC column, the VOCs are trapped and concentrated by the microtrap. Desorption of the VOCs is …

Use Of Riparian Vegetated Filter Strips To Reduce Nitrate And Fecal Contamination In Surface Water, Mark S. Coyne, Robert L. Blevins, Rebecca A. Gilfillen
KWRRI Research Reports
This research assessed fecal bacteria trapping in surface runoff by grass filters and their potential to enhance NO3- removal via denitrification. Grass filter strips 9.0 m long trapped over 99% of the soil in surface runoff in 1992. Fecal coliform removal was less than 75%. In 1993, 9.0 and 4.5 m grass filter strips trapped 99 and 95% of the sediment, respectively. Fecal coliform trapping efficiency was 90% in 9.0 m grass filters and 75% in 4.5 m filters. Fecal streptococci trapping efficiency was 77% in 9.0 m grass filters and only 56% in 4.5 m filters. Fecal …

Determining Recreational Visitor Carrying Capacity: The Case Of Black Canyon At Lake Mead National Recreation Area, Kenneth C. Forman
UNLV Theses, Dissertations, Professional Papers, and Capstones
Lake Mead and Lake Mohave, created by Hoover and Davis Dams respectively, were combined, along with much of the surrounding area, into the Lake Mead National Recreation Area in 1964. The enabling legislation is specific about the duty the National Park Service has to the public to create and maintain this, and other, national recreation areas for the benefit of the visitors, the environment, and future generations. By investigating human impacts on the physical environment (water quality, litter, etc.) and by querying park users on their opinions (with respect to crowding, visitor behavior, etc.), insight can be gained about appropriate …

Conference organizers and/or session moderators included University of Colorado School of Law professors David H. Getches, Judith Jacobsen, Lawrence J. MacDonnell, Teresa Rice and Charles F. Wilkinson.
Shifting policy objectives and management approaches for the public lands of the West are provoking heated debate about how these decisions should be made and implemented. Are these policy directions a reflection of the "New West" or are they, in fact, a declaration of "war on the West"? Somewhere between these polarities of view, efforts are underway to open dialogue and reach consensus.
This second annual western lands conference will explore federal initiatives …

Phosphorus Immobilization In Poultry Litter And Litter-Amended Soils With Aluminum, Calcium And Iron Amendments, D. M. Miller, P. A. Moore Jr., T. C. Daniels
Phosphorus Immobilization In Poultry Litter And Litter-Amended Soils With Aluminum, Calcium And Iron Amendments, D. M. Miller, P. A. Moore Jr., T. C. Daniels
Arkansas Water Resources Center Technical Reports
Arkansas produces approximately one billion broilers each year. Phosphorous (P) runoff from fields receiving poultry litter is believed to be one of the primary factors affecting water quality in Northwest Arkansas. Poultry litter contains approximately 20 g P kg-1, of which about 2 g P kg-1 is water soluble. Soils that have received repeated heavy applications of litter may have water soluble P contents of as high as 10 mg P Kg-1 soil. The objective of this study was to determine if soluble P levels could be reduced in poultry litter and litter-amended soils with Al,Ca, and/or Fe amendments. Poultry …

Bobcats, Dallas Virchow, Denny Hogeland
Prevention and Control of Wildlife Damage Handbook
The bobcat (Lynx rufus), alias “wildcat,” is a medium-sized member of the North American cat family. It can be distinguished at a distance by its graceful catlike movements, short “bobbed” tail, and round face and pointed ears. Visible at close distances are black hair at the tip of the tail and prominent white dots on the upper side of the ears. Body hair color varies, but the animal’s sides and flanks are usually brownish black or reddish brown with either distinct or faint black spots. The back is commonly brownish yellow with a dark line down the middle. …
