Southern Nevada Effluent Wetlands: A Proposed Cooperative Venture Between The Bureau Of Reclamation & City Of Las Vegas, Bureau Of Reclamation

Publications (WR)

Throughout North America there is a growing interest in constructed wetlands, both as relatively inexpensive, low-maintenance systems for removing nutrients from wastewater, and as a means of using municipal wastewater to enhance wildlife habitat and create public use opportunities. Because wetlands appear to have good potential as a component in the overall management of scarce water resources, the Bureau of Reclamation (Reclamation) has undertaken several cooperative research and demonstration projects to evaluate their effectiveness in a variety of local environments. While a number of projects have demonstrated that wetlands can be beneficially employed to improve water quality, few such projects …

Bulletin No 4216 - Broadscale Boom Spraying, Roger Doyle, Gary Dorr, Des Gilbey, John Peirce

Bulletins 4000 -

For spraying to be effective it must do the job required at a minimum cost, with no unwanted side effects. It is impo1tant to use the right chemical at the right rate, at the right tin1e and in the best conditions.

It is just as important that both the sprayer and the way it is used allows you to meet this objective. This Bulletin will help you select the right boom sprayer, maintain it for efficient operation and use it efficiently and safely.

Bulletin No 4131- Electric Fencing, Dean Maughan

Bulletins 4000 -

Fencing has always been an integral part of our agricultural system. We need fences for stock control and pasture management. Traditionally, fences have been strong and robust physical barriers. The strength and height of the fence kept domestic animals confined. For many years, conventional fences have served the farmer well. However because returns from livestock over the past ten years have been variable and because of the current cost/ price squeeze, electric fencing, as a cheaper form of fencing, has gained popularity.

Lake Mead Nutrient Enhancement Project, Peter D. Vaux, Larry J. Paulson, Nevada Department Of Wildlife, National Oceanic And Atmospheric Administration

Publications (WR)

The Lake Mead Fertilization Project is a research program designed to investigate the potential for using large-scale artificial fertilization to enhance the game fisheries of this reservoir through an increase in the population of threadfin shad, the system's primary forage species. A substantial decline in the population of largemouth bass, together with poor condition of adult striped bass, are the two major issues affecting the Lake Mead game fisheries. Both issues have been hypothesized to be a result of an inadequate amount of forage in the reservoir. Previous studies have in turn suggested that a major factor limiting the shad …

Environmental Assessment Of Las Vegas Wash And Lake Mead Artificial Wetlands Demonstration Project, John R. Baker, R. M. Gersberg, U.S. Environmental Protection Agency

Publications (WR)

The effective use of artificial wetlands for treatment of municipal wastewater is well documented; however, design and economic data for artificial wetlands development are limited (Gersberg et al., 1984a). This is due partly to regional differences in climate, soils, and vegetation and partly to the desired waste treatment. As a result, specific treatment levels and cost benefits relative to the use of an artificial wetlands for a particular site cannot be evaluated adequately without a pilot demonstration project. Las Vegas Wash receives sewage effluent from the Las Vegas metropolitan area and has been designated as a wetlands community park. Las …

Thermal Desorption Of Hazardous And Toxic Organic Compounds From Soil Matrices : Dichloromethane, Chloroform, Benzene, Toluene, 1-Chloronaphthalene, 1, 2, 4-Trichlorobenzene, Arun S. Chemburkar

Theses

This research project was undertaken to understand the process of desorption/removal of organic compounds from soil matrices under the influence of temperature and gas purging. The project was divided in two parts :

A. Plug deposition experiments: Columns packed with soil matrices were purged with an inert gas under isothermal conditions. Organic compounds were then introduced as a plug on the front of the column by on-line injection. The rate of passage (due to sequential adsorption/desorption) of the plug through the various soil matrices was measured by a gas chromatograph equipped with a flame ionization detector (FID). The compounds studied …

The Distribution Of Chlorine And Iodine In Soil In The Vicinity Of Lead Mining And Smelting Operations, Bixby Area, S.E. Missouri, U.S.A., R. Fuge, M. J. Andrews, T. E. Clevenger, B. E. Davies, Nord L. Gale, C. F. Paveley, B. (Bobby) G. Wixson

Biological Sciences Faculty Research & Creative Works

Iodine and Cl are enriched in soils in the vicinity of the Magmont and Buick lead mines near Bixby, southeastern Missouri. The enrichments, up to 5.6 ppm I and 305 ppm Cl, are against regional background of 1.26 ppm I and 41 ppm Cl. The area of highest I and Cl is thought to reflect a zone of base metal sulphide mineralization occurring about 400 m below the surface. Iodine and Cl are also enriched in soils immediately adjacent to a tailings pond, hence these elements would appear to be leached from this source. A zone of enhanced I values …

Degradation Of Aniline And Nitrobenzene In A Photoreactor, Michael Joseph Sowa

Theses

Degradation of aniline and nitrobenzene in aqueuous solutions was studied. Five reaction processes were utilized, including ultraviolet light, ozone, O₂/UV, O₃/O₂/UV, and H₂O₂/UV. A 30 liter semi-batch gas sparged reactor was used for the development of reaction rate and mass transfer parameters in these systems. The results were used to model a continuous stirred tank reactor (CSTR) for the O₃/O₂/UV case. Reasonable agreement was obtained for steady state exit concentrations between the experimental data and those predicted from the model.

Thermal Decomposition Of Dichlorobenzene In An Atmosphere Of Hydrogen And Helium, Mingta Hung

Theses

Reactions of dilute mixtures of dichlorobenzene in hydrogen and in helium were studied in a tubular reactor at a pressure of 1 atm, residence times of 0.04 to 2.7 seconds, and temperature range of 825 to 1000° C. Product distributions at various reaction conditions are measured with a flame ionization detector gas chromatograph, and qualitative analysis of batch samples was also performed by GC/Mass Spectrometry. The major products were observed as the thermodynamically stable species, HC1, Cis), benzene and chlorobenzene. Thermal reaction in helium at 1 second residence time in 1.05 cm ID reactor yielded less benzene and chlorobenzene when …

Agenda: Water As A Public Resource: Emerging Rights And Obligations, University Of Colorado Boulder. Natural Resources Law Center

Water as a Public Resource: Emerging Rights and Obligations (Summer Conference, June 1-3)

Conference organizers and/or faculty included University of Colorado School of Law professors Lawrence J. MacDonnell, David H. Getches, and Charles F. Wilkinson.

This conference focused on the legal rights associated with a broad range of public uses and interests in water including recreation, fish and wildlife protection, and water quality. Evolving legal areas such as the public trust doctrine, instream flow laws, federal reserved rights, and wetlands protection were discussed.

Water as a Public Resource: Emerging Rights and Obligations considered the extension of the public trust doctrine to areas previously not covered by this concept, as well as developments in …
