East Canyon Reservoir Water Intake Structure Final Environmental Assessment And Finding Of No Significant Impact, United States Department Of The Interior, Bureau Of Reclamation

Environmental Assessments (UT)

The purpose of the proposed action is to authorize SWDC to build and operate facilities to deliver water to the Park City/Snyderville Basin area (Figure 1.2). The need for the proposed action is a growing demand for water in the Park City/Snyderville Basin area due to population growth and increased development of recreation facilities and vacation homes.

Residential Water Demand Under Alternative Rate Structures: Simulation Approach, David E. Rosenberg

Civil and Environmental Engineering Faculty Publications

Econometricians have long studied the effect of price on residential water demand and the impact on water use of the rate (tariff) structure in which price signals are embedded. This paper applies an existing deductive model of residential water use for the intermittent supply system in Amman, Jordan and simulates demand responses across a cross section of households over many uniform, increasing block, and linear price (quadratic charge) rate structures at historically low and significantly higher prices. Results show inelastic piped water demand responses for all rate structures at historically low prices similar to findings from a prior econometric study …

Lead Detection In Water: Using Hydroxyapatite And Atomic Absorption, Nicolas Cantarero

Department of Environmental Studies: Undergraduate Student Theses

Hydroxyapatite is a mineral that is very inexpensive, easily made, and binds well to lead. In this procedure its application will be paired with Flame Atomic Absorption Spectroscopy (Flame AA) to detect lead concentrations in water to ppb levels. While ppb concentrations of lead are too dilute to produce a response from the Flame AA by using Hydroxyapatite to concentrate lead molecules from a larger volume and dissolving the Hydroxyapatite into a smaller volume it may be able to produce a response. The method could provide an inexpensive, efficient, and accurate way to detect lead concentrations to the ppb level …

The Burden Of Fetching Water: Using Caloric Expenditure As An Indicator Of Access To Safe Drinking Water—A Case Study From Xieng Khouang Province, Lao Pdr, Jeff La Frenierre

Electronic Theses and Dissertations

The Millennium Development Goals measure ‘access to improved drinking water’ using an indicator that defines access as the presence of an improved water source within 1 kilometer of a person’s dwelling. This purely linear measurement has significant shortcomings, including a lack of consideration for the difficulty of the terrain being traversed and the weight of the loads being carried. This paper examines in detail the human energy costs associated with fetching water, first using two Lao villages as case studies, then applying a predictive energy expenditure model to measure the potential caloric effect of variations in the age and gender …

Tailings Tale: Mike Horse Looms Dark Over The Blackfoot, Elizabeth L. Harrison

Graduate Student Portfolios, Professional Papers, and Capstone Projects

In the spring of 1975, a heavy rain blew out an earthen dam holding back toxic metal waste from the now defunct Mike Horse mine at the headwaters of the scenic Big Blackfoot River. Federal agencies, a corporate mining giant, and the small town community of Lincoln, Montana, grapple with the repercussions and future of the watershed.

Biogeochemical Behavior Of Dissolved Arsenic And Uranium Concentrations In Public Water Supply Wells, Kevin J. Mcvey

School of Natural Resources: Dissertations, Theses, and Student Research

Public water supply (PWS) wells currently contain dissolved uranium concentrations above the federally mandated maximum contaminant level (MCL) of 30 ppb (parts per billion) and dissolved arsenic concentrations above the 10 ppb MCL. Both uranium and arsenic are known to cause various forms of cancer in humans. Variations in total uranium concentrations in PWS wells in Nebraska indicate a relationship to the duration and rate of pumping in specific wells. Although total arsenic concentrations show some variability over time in specific wells, the relationship to pumping is not as clear. Previous studies show that iron and sulfur bacteria present in …

Water Quality Variability In A Bioswell And Concrete Drainage Pipe, Southwest Lincoln, Nebraska, Jessica Shortino

Department of Environmental Studies: Undergraduate Student Theses

Abstract The goal of this project is to evaluate the effectiveness of bioswells in protecting water quality from urban runoff. The hypothesis tested in this project is that water in bioswells improves water quality. Water quality in both a bioswell and an underground concrete lined ditch, both containing ground and surface water, were tested for certain water quality parameters. These parameters consisted of: Dissolved Oxygen, pH, water temperature, weather temperature, Total Dissolved Solids, Specific Conductivity, Alkalinity, Total Dissolved Carbon, Chemical Oxygen Demand, and depth and width of the sampling site. An additional contaminant that was looked at was motor oil. …

The Occurrence Of Illicit And Therapeutic Pharmaceuticals In Wastewater Effluent And Surface Waters In Nebraska, Shannon L. Bartelt-Hunt, Daniel D. Snow, Teyona Damon, Johnette Shockley, Kyle Hoagland

Nebraska Water Center: Faculty Publications

Passive samplers were used to develop semi-quantitative estimates of pharmaceutical concentrations in receiving waters influenced by wastewater effluent. The occurrence and estimated concentration of twenty illicit and therapeutic pharmaceuticals and metabolites in surface waters influenced by wastewater treatment plant (WWTP) discharge and in wastewater effluents in Nebraska were determined using Polar Organic Chemical Integrative Samplers (POCIS). Samplers were installed in rivers upstream and downstream of treated WWTP discharge at four sites and in a discharge canal at a fifth location. Based on differences in estimated concentrations determined from pharmaceuticals recovered from POCIS, WWTP effluent was found to be a significant …

Characterization Of Iron Oxide Thin Films For Photoelectrochemical Hydrogen Production, Kyle Eustace Nelson George

UNLV Theses, Dissertations, Professional Papers, and Capstones

Solar energy is the most sustainable source of energy available. However, solar applications such as photovoltaic cells represent only a partial solution to weaning our dependence upon fossil fuels. Several methods of storing solar energy are currently being pursued, and chemical storage stands out as a promising option - combining design simplicity with high energy density, with hydrogen being particularly attractive because of its abundance and inherently clean nature. A monolithic Photoelectrochemical (PEC) device that produces hydrogen by electrolyzing water directly from sunlight has the benefit of utilizing "free" solar energy to drive the reaction.

Water Use And Natural Limits In The Las Vegas Valley: A History Of The Southern Nevada Water Authority, Christian Harrison

UNLV Theses, Dissertations, Professional Papers, and Capstones

This thesis examines the history of the Southern Nevada Water Authority (SNWA) and how it has helped transform various aspects of southern Nevada's economy and environment. Prior to the establishment of the SNWA in 1991 the Las Vegas Metropolitan Area (LVMA) possessed several competing water providers whose opposition to one another adversely affected the management of water in the region. These water providers recognized this problem, came together, and negotiated the creation of a regional water agency, the SNWA. This organization, comprised of representatives from each of the LVMA's water providers has the power to institute policy across municipal boundaries. …

Populations Of Vibrio Vulnificus And Vibrio Parahaemolyticus In Breton Sound And Barataria Bay, Brian William Matherne

LSU Master's Theses

Vibrio vulnificus and Vibrio parahaemolyticus are halophilic gram-negative bacteria that are found in warm coastal waters. These two species are the leading cause of fatal shellfish poisoning. The objective of this study was to determine the population dynamics of V. vulnificus and V. parahaemolyticus as impacted by temperature and salinity in Breton Sound and Barataria Bay of Louisiana. Water samples were collected from each water body along s salinity gradient transect monthly from September 2007 through July 2009. Furthermore, from March 2008 through July 2009 sediment and live oyster samples were collected exclusively from the Breton Sound. The population of …
