Ozonation is a promising treatment step for water reuse. Compared to the “gold standard” with reverse osmosis and advanced oxidation, ozone requires less energy and does not result in a waste brine. This makes ozone more cost-effective. However, the formation of nitrosamines may be a significant barrier to the use of ozonation in water reuse applications, particularly for potable reuse.

How Much Water Does Las Vegas Use?
Water Use Per Capita
The average household in Southern Nevada uses about 222 gallons of water per day. This has recently dropped from using 314 gallons of water per day. The southern Nevada Water Authority hopes that by the year 2035, water use will have dropped down to 199 gallons per day for each household.
The majority of Southern Nevada’s water goes to residential use, both indoor and outdoor. Because of this, restrictions have been placed on certain aspects of water use such as the amount of lawn a household can own. Aside …

Water Consumption In Southern Nevada, Paul Conyers
COLA 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 …

College of Engineering: Graduate Celebration Programs
Project Background
• Many rural areas on the planet do not have easy access to clean water!
• Water distillation basins are capable of distilling water by using incident solar radiation to evaporate polluted water.
• Current thermodynamic models used to predict behavior require instantaneous data; requires the use of expensive equipment.
• Distillation basins are dependent on multiple meteorological variables: insolation, temperature, wind speed, cloud cover.
• Non‐linear behavior is difficult to predict for long term operations.
Impact Of Sludge Treatment Processes On Estrogen Concentration In Wastewater Sludge, Erica Marti
Impact Of Sludge Treatment Processes On Estrogen Concentration In Wastewater Sludge, Erica Marti
College of Engineering: Graduate Celebration Programs
Endocrine-disrupting compounds (EDCs), such as estrogen, are known to be present in the aquatic environment at concentrations that affect fish and other wildlife. For example, juvenile male fish exposed to estrogen will synthesize vitellogenin, which is a female-specific protein. Estrogen exposure is also linked to sex reversal, intersexuality, and inhibition of gonadal growth (Jobling et al., 1996).
Wastewater treatment plants are major contributors of EDCs into the environment. EDCs end up in wastewater as a result of natural excretion from the body or being washed off the skin. WWTPs are not designed to remove these substances. As a result, EDCs …

Groundwater: Solution To The Las Vegas Water Problem?, Rosa Perez, Christopher Ruiz
Festival of Communities: UG Symposium (Posters)
A contentious debate is taking place in different sectors of the community on how to manage the states groundwater system. It is a battle whose outcome, regardless of who wins, will have a tremendous impact on the future of Las Vegas. Economic benefits always seem to downplay environmental considerations in the policy-making process often with serious consequences. This paper takes a look at the SNWAʼs Groundwater Development Project and provides a discussion of the issues for and against it. Groundwater is inexpensive, relatively abundant and accessible. However, over-pumping of groundwater can have significant environmental consequences, as well. It is our …

Monitoring Water Quality On Tributary Inflows To Lake Mead And On A Transect Of The Overton Arm, Jorge Arufe, Robert Burrows
Lake Mead Science Symposium
The USGS, in cooperation with the NPS and BOR (Bureau of Reclamation), is collecting water quality data to determine the temporal changes and spatial distributions of natural and anthropogenic compounds entering the Overton Arm of Lake Mead. These efforts and others already underway on the lake by BOR, USGS, and SNWA will aid in the development of a reservoir model of the lake. The effects of the flood flows on the water quality of the Overton Arm are largely unknown and necessary for model development and verification.
Water quality physical parameters are continuously monitored near the mouth of the Virgin …

History Of Contaminant Inputs Into Lake Mead Derived From Sediment Cores, Michael R. Rosen, Peter C. Van Metre, David Alvarez, Kathy R. Echols, Steven L. Goodbred
Lake Mead Science Symposium
Assessing the changes in contaminant inputs (both organic and inorganic) over time is important in determining sources and sinks of these inputs. Variations in contaminant input were assessed in four sediment cores taken in 1998 from three different parts of Lake Mead (two from Las Vegas Bay and one from Overton Arm and Virgin Basin). Sediments were analyzed for major and trace elements, radionuclides, and organic compounds. Anthropogenic contaminant concentrations are greatest in Las Vegas Bay reflecting inputs from the Las Vegas urban area, although concentrations are low compared to sediment quality guidelines and to other USA lakes. One exception …

Session 7 - Technology And The Creation Of Wilderness: The Making Of Quabbin Reservoir, Timothy J. Farnham
Session 7 - Technology And The Creation Of Wilderness: The Making Of Quabbin Reservoir, Timothy J. Farnham
International Symposium on Technology and Society
Large dams in the United States have frequently been the targets of attacks by environmentalists who believe that the dams and the reservoirs they create are violations of wilderness. There are currently numerous proposals to dismantle some dams in order to restore river ecosystems to their pre-dam conditions, including Hetch Hetchy Reservoir’s O’ Shaunnessy Dam. Less attention has been paid to those dams and reservoirs that have arguably created protected areas that otherwise may have been subject to degradation from development. The Quabbin Reservoir, the primary water source for metropolitan Boston, serves as a prime example. Viewed as an engineering …
