Public Participation Program Development: An Analysis Of Public Participation In The Water Industry, Marcia Lynne Holmberg

UNLV Theses, Dissertations, Professional Papers, and Capstones

The field of public participation is a distinct, but yet unpolished facet within the public relations industry. While the purpose of and need for public participation are becoming increasingly clear, many remain unaware or unconvinced of its advantages. Likewise, even among those who endorse the necessity of public participation, its methods and strategies continue to be a mystery to most.

One industry, in particular, that has recognized and embraced the benefits of conducting public participation is the water utility industry. The purpose of this thesis is to 1) crystallize the understanding of why public participation is a necessary and advantageous …

A Plan For Characterizing Waste For The Defense Special Weapons Agency At The Nevada Test Site, Tiffany A. Hatcher

UNLV Theses, Dissertations, Professional Papers, and Capstones

In 1976, Congress adopted the Resource Conservation and Recovery Act (RCRA) to govern hazardous waste. The Act was amended in 1984 with the Hazardous and Solid Waste Amendments in order to further define the requirements of RCRA. RCRA is meant to protect human health and the environment from the effects of hazardous waste, promote waste minimization, and encourage material recycling and recovery. For this purpose, regulations are implemented that cover every aspect of the hazardous waste problem, including generation, transport, treatment, storage, and disposal.

Generators of waste are the most important part of this chain. As defined in RCRA, a …

Volcanology And Geochemistry Of Pliocene And Quaternary Basalts On Citadel Mountain, Lunar Crater Volcanic Field, Pancake Range, Nevada, Loretta D. Dickson

UNLV Theses, Dissertations, Professional Papers, and Capstones

Alkali basalts on Citadel Mountain form the southern margin of the Lunar Crater Volcanic Field (LCVF) in the central Great Basin, Nevada. Citadel Mountain comprised of a faulted, north tilted section of Tertiary andesite and ash-flow tuff is capped by Pliocene and Quaternary alkali basalt flows that erupted from six major cinder cones. The basalt flows on Citadel Mountain can be divided into two groups (older and younger) based on age and isotopic signatures. The older basalt group is characterized by higher ⁸⁷ Sr/⁸⁶Sr and lower E_Nd and the younger group has lower ⁸⁷Sr/⁸⁶Sr …

The Use Of Spectrofluorimetry And Capillary Electrophoresis/Laser-Induced Fluorescence For The Detection Of Fluorescent Dyes In Groundwater Migration Studies, Patrick Ferguson

UNLV Theses, Dissertations, Professional Papers, and Capstones

This thesis involves work that was accomplished during a two-year internship at the Environmental Protection Agency's (EPA), Environmental Chemistry Branch. The research is an application of trace level determination of fluorescein dyes used as groundwater tracers. The work was performed to determine whether groundwater could migrate from a Resource Conservation Recovery Act (RCRA) site to an adjacent Superfund site. The research involved using Spectrofluorimetry and a new technique called capillary electrophoresis/laser induced fluorescence (CE/LIF) to determine tracer dyes that were injected at the RCRA site and monitored at the Superfund site. Results from Spectrofluorimetry were compared to those of CE/LIF. …

Blm Rangeland: Has The Condition Improved?, Angela C. Dudley

UNLV Theses, Dissertations, Professional Papers, and Capstones

"Whose Home Is the Range, Anyway?: The latest research is confirming that in the West's fragile public lands, cattle are often bad news for wildlife." This is the title and headline of Lisa Drew's article in the December/January 1994 issue of National Wildlife. It shows a picture of what looks like a wasteland with only cattle, manure and a fence, no vegetation (Drew, 1994). Inside the article, Drew quotes biologist Bob Ohmart at Arizona State University's Center for Environmental Studies as saying, "Livestock grazing is without a doubt the greatest threat to western wildlife" (p. 15). Drew contends that, "The …

The Eldorado Landfill: A Case Study, Heather A. Nash

UNLV Theses, Dissertations, Professional Papers, and Capstones

In 1995, Boulder City bought from the federal government 167 square miles of land in the Eldorado Valley which is located approximately seven miles west of the city. Soon afterward, the current landfill in Boulder City began accepting construction waste from Las Vegas. The large dump trucks had to travel through Boulder City on route to the landfill. In doing this they passed through three school zones and residential areas. When residents began complaining about the trucks, the Boulder City City Council began investigating various ways to solve the problem. The solution they adopted was to construct a new landfill …

Recycling At Work: Waste Reduction And Recycling In The Las Vegas Hospitality Industry, Darlene M. Cartier

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Las Vegas hotel and restaurant industries generate 27% of the total waste for Clark County, Nevada. In an effort to study and increase recycling participation in the hospitality industry, Las Vegas hotels and restaurants were contacted to participate in a collaborative project between UNLV's Department of Environmental Studies and the Clark County Health District's Environmental Health Division, The project involved interviewing establishments with recycling programs currently in place. Information gathered from interviews and program tours was used to develop programs for hotels and restaurants who were not yet recycling. This thesis contains case studies of restaurants and hotels who …

Critical Evaluation Of The Double Tracks Remediation Project, Craig J. Barnes

UNLV Theses, Dissertations, Professional Papers, and Capstones

The U.S. Atomic Energy Commission (AEC) (now the U.S. Department of Energy), in testing the safety of nuclear weapons under many different conditions, detonated single plutonium bearing devices in such a fashion as to simulate an unintentional detonation of the high-explosive portion of nuclear weapons. This resulted in the uncontained spread of plutonium and other radionuclides, such as americium and depleted uranium, in the environment in the vicinity of these experiments. The Double Tracks site was one of these experiments on the Tonopah Test Range (TTR) which was contaminated hi excess of 200 picocuries per gram (pCi/g). The Double Tracks …

Composting Landscape Waste From The University Of Nevada, Las Vegas, K. Jill Hammond

UNLV Theses, Dissertations, Professional Papers, and Capstones

The University of Nevada, Las Vegas is a major producer of organic waste in the Las Vegas Valley. Composting landscape wastes is one way to reduce both landfill dumping and fertilizer costs for the university. It is also an environmentally friendly means of curbing a nationwide problem: unnecessary use of landfill space. Three sites within Clark County were analyzed for the feasibility of composting: Frenchman Mountain, UNLV Campus, and Boulder City Landfill. Using cost analysis, water availability, and other factors to analyze each site, Boulder City Landfill appears to be the best place to house UNLV's composting operation. Composting in …
