Assessment Of A Modified Double Agar Layer Method To Detect Bacteriophage For Assessing The Potential Of Wastewater Reuse In Rural Bolivia, Sakira N. Hadley

USF Tampa Graduate Theses and Dissertations

Water scarcity is a global concern that impacts many developing countries, forcing people to depend on unclean water sources for domestic, agricultural, and industrial needs. Wastewater is an alternative water source that contains nutrients needed for crop growth. Wastewater reuse for agriculture can cause public health problems because of human exposure to pathogens. Pathogen monitoring is essential to evaluate the compliance of wastewater with established World Health Organization (WHO) and U.S. Environmental Protection Agency (EPA) wastewater reuse guidelines. Indicator organisms are commonly used to detect pathogens in water and wastewater because they are quick and easy to measure, non-pathogenic, and …

Turning Water Into Wine: The Political Economy Of The Environment In Southern California's Wine Country, Jason Simms

USF Tampa Graduate Theses and Dissertations

This dissertation examines questions of water sustainability in contexts of wine production and state-led neoliberal development in the Temecula Valley, southern California, where wine tourism is at present being harnessed as an engine of economic growth. Natural and anthropogenic forces, such as global climate change, desertification, urban development, and the marketization and commodification of natural resources, affect the distribution and availability of water throughout the globe. As a result, the use of water, and associated political and environmental processes and consequences, in the production of global commodities, including wheat, citrus, and coffee, recently have come under increased scrutiny. Given wine's …

Flexible Urban Water Distribution Systems, Seneshaw Amare Tsegaye

USF Tampa Graduate Theses and Dissertations

With increasing global change pressures such as urbanization and climate change, cities of the future will experience difficulties in efficiently managing scarcer and less reliable water resources. However, projections of future global change pressures are plagued with uncertainties. This increases the difficulty in developing urban water systems that are adaptable to future uncertainty.

A major component of an urban water system is the distribution system, which constitutes approximately 80-85% of the total cost of the water supply system (Swamee and Sharma, 2008). Traditionally, water distribution systems (WDS) are designed using deterministic assumptions of main model input variables such as water …

The Water Culture Beliefs Of Embera Communities And Maternal And Child Health In The Republic Of Panama, Ilenia Anneth Forero

USF Tampa Graduate Theses and Dissertations

Water has cultural and spiritual values to indigenous people. These beliefs expose them to unsafe water sources and make them vulnerable to waterborne diseases. This background is not taken into account when countries write their water legislations, therefor imposing a management of water not readily accepted by them. The Embera group is one of the indigenous groups from the Republic of Panama, who have strong water beliefs. They live along the shore of rivers in houses built on high stilts away from urban areas. The purpose of this cross-sectional community based study is to describe through a survey the relation …

Insight Into The Use, Perception, And Value Surrounding Domestic Water In Peru: Envisioning Demand Management In An Intermittent, Small-City, Service Context, Merril Augusta Putnam

USF Tampa Graduate Theses and Dissertations

Population growth, urbanization, degrading water quality, and climate change are making management of scarce water resources an increasingly difficult task for the domestic sector. It is recognized that in order to manage urban water resources demand management is requisite. Demand management has been experimented with in large cities of developing countries but continued focus on expanding supply overshadows its potential benefits and ultimate success. In order to manage demand, it must be measured and understood. Intermittent water services are prevalent in developing countries, but unmetered domestic water use under such conditions has not been carefully studied. This study conducted 1,149 …

Time Scale Of Groundwater Recharge: A Generalized Modeling Technique, Makhan Virdi

USF Tampa Graduate Theses and Dissertations

Estimating the quantity of water that reaches the water table following an infiltration event is vital for modeling and management of water resources. Estimating the time scale of groundwater recharge after a rainfall event is difficult because of the dependence on nonlinear soil characteristics and variability in antecedent conditions. Modeling the flow of water through the variably saturated zone is computationally intensive since it requires simulation of Richards' equation, a nonlinear partial differential equation without a closed-form analytical solution, with parametric relationships that are difficult to approximate. Hence, regional scale coupled (surface water - groundwater) hydrological models make simplistic assumptions …

Osmb Ais Funds Final Report: Task 1 Boat Ramp Monitoring For New Zealand Mud Snails, Valance Brenneis, Samuel Cimino, Angela L. Strecker

Center for Lakes and Reservoirs Publications and Presentations

The New Zealand mud snail (Potamopyrgus antipodarum; NZMS) is an invasive species found in a variety of ecosystems in Oregon, including brackish estuaries, heavily used recreational rivers, and highly trafficked coastal freshwater lakes. NZMS are an invasive species of concern because once established, they may out-compete native invertebrate grazers, such as native insect larvae that provide important food resources for fish, and NZMS themselves provide little nutritional value. Monitoring for the presence and population density of NZMS was performed at boat ramps located along several water bodies in 2006 – 2007. These water bodies were then re-sampled during the summer …

Improving Urban Run-Off Quality Using Iron Oxide Nanoparticles With Magnetic Field, Mehdi Khiadani, Mohammad Mehdi Foroughi, Mohammad Mehdi Amin

Research outputs 2013

Run-off from road surfaces is a major source of pollution in the environment. The aim of this study was to investigate the efficiency of nano iron oxide under a magnetic field to improve urban run-off quality. Experiments were conducted in a 50mm diameter column made of Plexiglass in which 20 cm deep stainless steel wool was used as the medium bed. A pair of magnets, each with 0.7 T magnetic charge density, was installed around the column. The particle size of the iron oxide was determined by X-ray diffraction (XRD) analysis. Atomic absorption spectroscopy, spectrophotometer, turbidimeter, and pH meter were …

Removal Of Turbidity From Water By Dissolved Air Flotation And Conventional Sedimentation Systems Using Poly Aluminum Chloride As Coagulant, Mehdi Khiadani, Reza Kolivand, Matin Ahooghalandari, Maral Mohajer

Research outputs 2013

Flotation is a method in which particles in liquid phase are transported to the surface by air bubbles. In this experimental study, a comparison has been made between conventional sedimentation and dissolved air flotation (DAF) systems to remove turbidity from water. Initially, optimal operational conditions for each system utilized using water artificially turbid with Kaolin. For each system, samples were taken at 20-min interval after the system reached its optimal operational conditions. Parameters, such as turbidity, alkalinity, temperature, pH, and total suspended solids, were measured. For 20, 30–50 and 90–110 NTU, turbidity average removal efficiencies in DAF system were 14.7, …

Mine Closure Of Pit Lakes As Terminal Sinks: Best Available Practice When Options Are Limited?, C. D. Mccullough, G. Marchand, J Unseld

Research outputs 2013

In an arid climate, pit lake evaporation rates can exceed influx rates, causing the lake to function as a hydraulic terminal sink, with water levels in the pit remaining below surrounding groundwater levels. We present case studies from Western Australia for two mines nearing closure. At the first site, modelling indicates that waste dump covers for the potentially acid forming (PAF) material would not be successful over the long term (1,000 years or more). The second site is a case study where PAF management is limited by the current waste rock dump location and suitable cover materials. Pit lake water …

Water Consumption In Southern Nevada, Paul Conyers

Anthropology 100: Feast and Famine In a Global World Poster Assignment

With its massive hotels, casinos, restaurants, and dramatic architecture it can be easy to forget that Las Vegas resides in the middle of a desert receiving just 4.5 inches of rain per year. Its population has grown immensely to nearly 2 million as of 2012 and that is without including the more than 30 million tourists visiting every year. With this growth more and more water is needed to keep yards and golf courses green, to keep the fountains of Bellagio flowing, to support the habitats of Mandalay Bay and the Flamingo, and to allow Las Vegas to maintain its …
