United States Environmental Protection Agency: Publications

Several participants in Phase 2 of the Air Quality Model Evaluation International Initiative (AQMEII-2) who are applying coupled models to the North American domain are comparing model results for two years, 2006 and 2010, with the goal of performing dynamic model evaluation. From a modeling perspective, the differences of interest are the large reductions in domain total emissions of NO_x (21%) and SO₂ (37%) from 2006 to 2010 and significant differences in meteorological conditions between these two years. The emission reductions occurred mostly in the eastern U.S, with some reduction in emissions from western wildfires in 2010. Differences …

Potential Aquifer Vulnerability In Regions Down-Gradient From Uranium In Situ Recovery (Isr) Sites, James A. Saunders, Bruce E. Pivetz, Nathan Voorhies, Richard T. Wilkin

United States Environmental Protection Agency: Publications

Sandstone-hosted roll-front uranium ore deposits originate when U(VI) dissolved in groundwater is reduced and precipitated as insoluble U(IV) minerals. Groundwater redox geochemistry, aqueous complexation, and solute migration are important in leaching uranium from source rocks and transporting it in low concentrations to a chemical redox interface where it is deposited in an ore zone typically containing the uranium minerals uraninite, pitchblende, and/or coffinite; various iron sulfides; native selenium; clays; and calcite. In situ recovery (ISR) of uranium ores is a process of contacting the uranium mineral deposit with leaching and oxidizing (lixiviant) fluids via injection of the lixiviant into wells …

Identification Of Putative Geographically Isolated Wetlands Of The Conterminous United States, Charles R. Lane, Ellen D'Amico

United States Environmental Protection Agency: Publications

Geographically isolated wetlands (GIWs) are wetlands completely surrounded by uplands. While common throughout the United States (U.S.), there have heretofore been no nationally available, spatially explicit estimates of GIW extent, complicating efforts to understand the myriad biogeochemical, hydrological, and habitat functions of GIWs and hampering conservation and management efforts at local, state, and national scales. We used a 10-m geospatial buffer as a proxy for hydrological or ecological connectivity of National Wetlands Inventory palustrine and lacustrine wetland systems to nationally mapped and available stream, river, and lake data. We identified over 8.3 million putative GIWs across the conterminous U.S., encompassing …

The Role Of The State, Multinational Oil Companies, International Law & The International Community: Intersection Of Human Rights & Environmental Degradation Climate Change In The 21st Century Caused By Traditional Extractive Practices, The Amazon Rainforest, Indigenous People And Universal Jurisdiction To Resolve The Accountability Issue, Marcela Cabrera Luna

Master's Theses

Local, national and international conventions that protect indigenous sovereignty and their territories, where many of the resources are extracted from by multinational corporations (MNCs) particularly oil, the number one commodity of the world and cause of climate change, continue to be jeopardized because of the lack of a clear international legal framework that can protect them and potentially hold multinationals accountable for their actions. These practices are causing not only environmental issues to the indigenous and surrounding communities, but climate change is in fact, the real human rights issue of the 21^st century and it affects everyone. By using …

Seismic Surveys And Marine Turtles: An Underestimated Global Threat?, Sarah E. Nelms, Wendy Dow Piniak, Caroline R. Weir, Brendan J. Godley

Environmental Studies Faculty Publications

Seismic surveys are widely used in marine geophysical oil and gas exploration, employing airguns to produce sound-waves capable of penetrating the sea floor. In recent years, concerns have been raised over the biological impacts of this activity, particularly for marine mammals. While exploration occurs in the waters of at least fifty countries where marine turtles are present, the degree of threat posed by seismic surveys is almost entirely unknown. To investigate this issue, a mixed-methods approach involving a systematic review, policy comparison and stakeholder analysis was employed and recommendations for future research were identified. This study found that turtles have …

Patterns Of Anthropogenic Nutrient Contaminants In The Otter Creek Watershed, Madison County, Kentucky, Elijah D. Wolfe, Walter S. Borowski, Jacob L. Robin

EKU Faculty and Staff Scholarship

We measured nutrient concentrations within the Otter Creek watershed (Madison County, Kentucky) to: (1) discover levels of anthropogenic contaminants affecting the water quality; (2) compare these measurements to a national data set; and (3) identify nutrient sources. The watershed mainly drains rural land characterized by cattle grazing, but also drains the town of Richmond. We sampled throughout the watershed to gain a representative perspective of nutrient levels and specifically targeted localities of suspected anthropogenic nutrient sources. Water samples were passed through a 0.45 mm filter, placed in pre-acidified vials, and measured one to two days after collection. Nutrients – ammonium, …

Dreissenid Mussel Research Priorities Workshop, Mark D. Sytsma, Stephen Phillips, Timothy D. Counihan

Center for Lakes and Reservoirs Publications and Presentations

Currently, dreissenid mussels have yet to be detected in the northwestern part of the United States and western Canada. Infestation of one of the jurisdictions within the mussel-free Pacific Northwest would likely have significant economic, soci­etal and environmental implications for the entire region. Understanding the biology and environmental tolerances of dreissenid mussels, and effectiveness of various man­agement strategies, is key to prevention.

On November 4-5, 2015, the Aquatic Bioinvasion Research and Policy Institute and the Center for Lakes and Reservoirs at Portland State University, the US Geological Survey, and the Pacific States Marine Fisheries Commission, convened a Dreissenid Mussel Research …

United States Environmental Protection Agency: Publications

Due to their inherent phototoxicity and inevitable environmental release, titanium dioxide nanoparticles (nano- TiO₂) are increasingly studied in the field of aquatic toxicology. One of the particular interests is the interactions between nano-TiO₂ and natural organic matter (NOM). In this study, a series of experiments was conducted to study the impacts of Suwannee River natural organic matter (SRNOM) on phototoxicity and particle behaviors of nano-TiO₂. For Daphnia magna, after the addition of 5 mg/L SRNOM, LC50 value decreased significantly from 1.03 (0.89–1.20) mg/L to 0.26 (0.22–0.31) mg/L. For zebrafish larvae, phototoxic LC50 values were …

Mitigating The Risk Of Extreme Water Scarcity And Dependency: The Case Of Jordan, Joep F. Schyns, Arwa Hamaideh, Arjen Y. Hoekstra, Mesfin Mekonnen, Marlou Schyns

Daugherty Water for Food Global Institute: Faculty Publications

Jordan faces great internal water scarcity and pollution, conflict over trans-boundary waters, and strong dependency on external water resources through trade. This paper analyzes these issues and subsequently reviews options to reduce the risk of extreme water scarcity and dependency. Based on estimates of water footprint, water availability, and virtual water trade, we find that groundwater consumption is nearly double the groundwater availability, water pollution aggravates blue water scarcity, and Jordan’s external virtual water import dependency is 86%. The review of response options yields 10 ingredients for a strategy for Jordan to mitigate the risks of extreme water scarcity and …

The Environment And Civil War: Exploring The Relationship Between The Environmental Performance Index And Incidence Of Internal Armed Conflict, Katerina N. Krohn

Student Publications

The state of the environment is receiving increasing attention. Environmental quality’s possible relationship to violent conflict attracts both popular and academic interest. Prior research has found support for the idea that environmental scarcity is related to higher occurrences of civil war. There have been few comprehensive quantitative studies regarding this relationship. This study tests a more general argument that higher environmental quality can lead to fewer occurrences of internal armed conflict. The study utilizes an environmental performance index found in the Quality of Government Standard Dataset to test its hypothesis. The study finds that the higher the environmental performance index …

Why Financial Lending Institutions Are Not Willing To Provide Services To The Private Sector For Rural Sanitation And Hygiene (Malawi)., Rochelle H. Holm, Victor Kasulo, Elijah Wanda

Faculty and Staff Scholarship

This study examines the gap between financial lending institutions and sanitation and hygiene services within Nkhata Bay District, Malawi. The study reviewed literature and policies, and conducted interviews, field observations, focus group discussions, household and lending institutions surveys, and peer reviewed workshops. Results suggest the following recommendations: promoting informal financial services, improving access for “risky” customers, improving knowledge for financial service providers, and promoting loan diversity. Although it has been found in Malawi households are willing to pay, cash, for improved sanitation, build-up of private sector businesses is hampered by lending institutions not willing to provide financial services.

No time to waste: Crowdsourcing global wastewater treatment data

Worldwide, over 80 percent of wastewater is discharged into water bodies without undergoing treatment, severely impairing human well-being and ecosystem vitality along the way. National performance on wastewater treatment is difficult to quantify and is poorly understood due to a lack of common definitions, poor data collection standards, and limited historical data. To address this, the Yale Environmental Performance Index (EPI), a research group that produces a biennial ranking of country-level environmental performance, developed a first-of-its kind national wastewater treatment indicator.[1]

The indicator assesses wastewater treatment performance for 183 countries, …

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, …

The Human And Environmental Effects Of Cbrn Weapons, Brendan M. Doran

Student Theses 2015-Present

Since the first use of modern weapons of mass destruction during the First World War, the World has lived in fear of these horrifying instruments of death. Gripped by this fear, countries around the world have continued to research, develop, and test these weapons in the spirit of mutually assured destruction. Over the years, science and warfare have continually refined their methods of human extermination, bringing forth some of the most terrifyingly effective weapon systems ever devised. However, the testing and use of these weapons is often a step into the unknown. The repercussions of deploying these weapons are sometimes …

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 …

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 …

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 …
