Using Bromide Tracer To Measure Uranium Diffusivity In Ground Water Sediments, Francis Michael Tee, Morris E. Jones, Megan K. Dustin, Sharon Bone, John Bargar Aug 2015

Using Bromide Tracer To Measure Uranium Diffusivity In Ground Water Sediments, Francis Michael Tee, Morris E. Jones, Megan K. Dustin, Sharon Bone, John Bargar

STAR Program Research Presentations

More than 129 million liters of groundwater are contaminated with uranium at Old Rifle, Colorado – a former uranium-processing site that operated until 1958. The original Department of Energy (DOE) strategy for remediation, involving natural flushing of U from the groundwater through mixing with surface water, has not proven successful. Thin pockets of silt-, clay-, and organic-rich sediments referred to as naturally reduced zones (NRZs) act both as sinks and sources of U to the aquifer, contribute to plume persistence, and appear to be diffusion limited controlled.

To better understand how the NRZs are diffusion limited controlled, a bromide tracer …


Gender And Climate Change In The Indian Himalayas: Global Threats, Local Vulnerabilities, And Livelihood Diversification At The Nanda Devi Biosphere Reserve, Monica V. Ogra, Ruchi Badola Aug 2015

Gender And Climate Change In The Indian Himalayas: Global Threats, Local Vulnerabilities, And Livelihood Diversification At The Nanda Devi Biosphere Reserve, Monica V. Ogra, Ruchi Badola

Environmental Studies Faculty Publications

Global climate change has numerous implications for members of mountain communities who feel the impacts in both physical and social dimensions. In the western Himalayas of India, a majority of residents maintain a livelihood strategy that includes a combination of subsistence or small-scale agriculture, livestock rearing, seasonal or long-term migration, and localized natural resource extraction. While warming temperatures, irregular patterns of precipitation and snowmelt, and changing biological systems present challenges to the viability of these traditional livelihood portfolios in general, we find that climate change is also undermining local communities’ livelihood assets in gender-specific ways. In this paper, we present …

Environmental Social Activism In The San Diego-Tijuana Transborder Region, Christina M. Hirt May 2015

Environmental Social Activism In The San Diego-Tijuana Transborder Region, Christina M. Hirt

Undergraduate Honors Theses

This paper examines the obstacles and opportunities social activists face when attempting to fight environmental injustices in the San Diego-Tijuana transborder region. The study undertakes a case study of the Environmental Health Coalition (EHC) - the leading environmental justice organization in the region, which operates on both sides of the US-Mexico Border. The analyses conclude that despite a strong rhetoric of binationalism employed throughout border activists’ campaigns, the strategies that are utilized on the ground have been vastly local and short-term in focus. While activist organizations like the EHC demonstrate a keen awareness of the binational implications of environmental injustices …


Evaluation Of The Feasibility Of Struvite Precipitation From Domestic Wastewater As An Alternative Phosphorus Fertilizer Resource, Amanda R. Bird May 2015

Evaluation Of The Feasibility Of Struvite Precipitation From Domestic Wastewater As An Alternative Phosphorus Fertilizer Resource, Amanda R. Bird

Master's Projects and Capstones

Finite phosphate rock ore reserves are estimated to be exhausted in 100 to 150 years. Phosphate rock ore is the single global source material for phosphorus fertilizer production. Once these reserves are gone, agricultural production will be negatively impacted. There are currently no alternative phosphorus resources. However, phosphorus concentrations present in human excrement traveling through domestic wastewater treatment facilities is being disposed of directly to the environment, often resulting in pollution problems. Recovering phosphorus from wastewater with struvite precipitation systems at wastewater treatment plants can alleviate future phosphorus scarcities. Evaluation of phosphorus recovery through struvite precipitation at wastewater treatment plants …

Ecodistricts In San Francisco: The Implementation Of Neighborhood Regional Planning And Its Potential Effects On Environmental Resilience, Elizabeth M. Juvera

Master's Projects and Capstones

Ecodistricts, or neighborhood-scale, community-driven areas of sustainable development, have emerged internationally and within the U.S. to create models of adaptive environmental design and advanced urban infrastructure. Central SoMa is the first ecodistrict to be planned and implemented in San Francisco, with the intention of revitalizing and greening this urbanized region of the city. At this time, the Central SoMa area has very low biodiversity levels, inefficient infrastructure, and poor water management capabilities. Through the implementation of ecodistricts in San Francisco, the city can integrate physical and behavioral sustainability measures from existing ecodistricts such as permeable surfaces, green roofs, stormwater management, …


Surface And Subsurface Application Of Chemical Dispersants And Associated Ecosystem Impacts, Adam V. Radpour May 2015

Surface And Subsurface Application Of Chemical Dispersants And Associated Ecosystem Impacts, Adam V. Radpour

Master's Projects and Capstones

Chemical dispersants are applied to spilled oil in marine environments when other, less controversial, methods are not adequate for the incident. They are considered to be a response method as opposed to a direct cleanup method, with the intended goals of reducing risk of exposure to sensitive shorelines, reducing environmental injury to surface-dwelling sea birds and marine mammals, and facilitating the biodegradation of spilled oil into the water column.

For this research, both surface and subsurface application of dispersants were evaluated in terms of oil characteristics and volume, and oceanic and atmospheric conditions. More data exists to support the effectiveness …

Air Pollution Differences Between Nations With Different Economic Profiles, Alliyah Sato May 2015

Air Pollution Differences Between Nations With Different Economic Profiles, Alliyah Sato

Student Scholar Symposium Abstracts and Posters

The economics of a country plays an important role in determining what that country considers as its priorities. A developed country, such as the U.S., is powerful economically. As a result, it has the resources and tools to focus on other aspects of the nation. One of these features is the environment. Countries undergoing urbanization and industrial development processes, such as China, are emitting large amounts of pollutants into the atmosphere. Although it has adverse health and ecological effects, China has shown very little reduction of its emissions from 2000-2014. It relies heavily on coal burning as a source of …

Lead Hazard Control In Henderson, Nevada: Identifying Critical Areas And The Associated Costs, Khaye Gerazel Arcilla Rufin

UNLV Theses, Dissertations, Professional Papers, and Capstones

Lead poisoning is a common, yet preventable childhood health problem in the United States today. Studies show statistically significant (p < .05) associations between higher childhood lead exposure and subsequent negative developmental outcomes. Since 1993, the U.S. Department of Housing and Urban Development (HUD) Lead Hazard Control (LHC) Grant Program has devoted more than $1 billion in funding to several cities.

This study investigated a total of n=75 homes enrolled into the Henderson Lead Hazard Control and Healthy Homes Program (HLHCHHP) from December 2013 – February 2015. A logistic regression was performed to ascertain the frequency of lead-based paint (LBP) found in homes based on the year it was constructed. Of the 75 enrolled and tested for LBP, 58 homes (77.3%) were found to contain LBP and 17 homes (22.7%) did not contain LBP. The significance value of p=0.013 shows that …


Local Response To Climate Change: A Case Study Approach, Nora Gimpel Apr 2015

Local Response To Climate Change: A Case Study Approach, Nora Gimpel

Honors Theses

The scientific consensus on the causes and consequences of climate change is clear and experts continue to strongly recommend immediate mitigation and adaptation responses (IPCC, 2014). Responses to climate change are occurring at the international, national, and subnational level, but adaptation to climate change is also highly local. Local communities across the world are organizing groups and institutions to determine their best responses for local mitigation and adaptation actions. This study analyzed the formal local community organization, the Kalamazoo Climate Change Coalition (KCCC), and its structured activities in order to evaluate how Kalamazoo has responded to climate change. Methodology for …


On The Influence Of Ionic Strength On Radium And Strontium Sorption To Sandy Loam Soils, Brian A. Powell, Todd Miller, Daniel I. Kaplan Apr 2015

On The Influence Of Ionic Strength On Radium And Strontium Sorption To Sandy Loam Soils, Brian A. Powell, Todd Miller, Daniel I. Kaplan

Journal of the South Carolina Academy of Science

Models which can estimate environmental transport of radioactive contaminants in natural and engineered systems are required to 1) deploy effective remediation strategies for contaminated sites, 2) design waste repositories for future waste streams, and 3) ensure protection of human and environmental health in all cases. These models require accurate transport parameters in order to correctly predict how these contaminants will move in the subsurface. This work aimed to determine more accurately the distribution coefficients for radium and strontium sorption to Savannah River Site (SRS) soils. Radium and strontium sorption to the soils was found to be highly dependent upon ionic …

Spatial And Temporal Relationships Between Forest Bird Declines And Prevalence Of The Hemlock Woolly Adelgid In The Northeastern United States, Julie E. Blum, Andrew M. Wilson

Student Publications

The eastern hemlock (Tsuga canadensis) is a vital foundation tree species throughout the eastern United States, providing essential structural diversity and habitat for more than 120 different animal species. Within the past few decades, T. canadensis has undergone significant declines that are largely associated with the hemlock woolly adelgid (HWA; Adelges tsugae), an exotic, aphid-like insect native to East Asia. From the 1970s to present day, the HWA has spread throughout southern New England, large portions of the Mid-Atlantic region, and parts of Tennessee and the Carolinas. Research has shown that loss of the eastern hemlock is …

Taming The Teesta: Exploring The Holistic Effects Of Hydroelectric Dam Development On The Teesta River Through Documentary Film, Taylor Graham

Independent Study Project (ISP) Collection

Since time immemorial, the Lepcha people have called the Himalayan region that makes up the modern state of Sikkim their home and have held sacred the rivers, mountains, and forests that make up the biologically diverse region. Over the past two decades, India’s rapid development has generated a powerful thirst for electricity, and the country has increasingly looked to the cold, powerful rivers thundering from the Himalayas to supply that desired power. Hydroelectric projects have been proposed and implemented throughout the Himalayan region. Nowhere, however, are the dams as numerous or their effects as acutely felt as in India’s northwestern …


The Himalayan Gold Rush The Untold Consequences Of Yartsa Gunbu In The Tarap Valley, Noah Stone Apr 2015

The Himalayan Gold Rush The Untold Consequences Of Yartsa Gunbu In The Tarap Valley, Noah Stone

Independent Study Project (ISP) Collection

Despite the fact that it has been used in tradition medicine for centuries, the caterpillar fungus known as yartsa gunbu (Othiocordyceps sinensis), has only become a popular medical supplement in the last fifteen years. Demand in China has driven what has been dubbed ‘the Himalayan gold rush’, a scramble for the fungus that has utterly transformed the agro-pastoral economies of the remote Himalayan regions where cordyceps is found. In many cases, the locals have prospered economically from the commodification of yartsa gunbu. In one such region of Nepal, the Tarap valley of the Dolpa district, while the villagers have benefitted …


Signed Peer Reviews As A Means To Improve Scholarly Publishing, Linwood H. Pendleton Mar 2015

Signed Peer Reviews As A Means To Improve Scholarly Publishing, Linwood H. Pendleton

Journal of Ocean and Coastal Economics

Peer review is a necessary process with a long history of complaints, including over-solicitation of a small number of reviewers, delays, inadequate numbers of reviewers, and a lack of incentives to provide strong reviews or avoid reviews with little helpful information for the author. In the era of Web-based distribution of research, through working paper or project reports, anonymous peer reviews are much less likely. The Journal of Ocean and Coastal Economics will use signed peer reviews and an open communication process among authors, reviewers, and editors. This approach, to be developed over time, should lead to stronger communication of …
