Managing The Risks Of Shale Gas Development Using Innovative Legal And Regulatory Approaches, Sheila Olmstead, Nathan Richardson 2015 College of William & Mary Law School

Managing The Risks Of Shale Gas Development Using Innovative Legal And Regulatory Approaches, Sheila Olmstead, Nathan Richardson

William & Mary Environmental Law and Policy Review

Booming production of oil and gas from shale enabled by hydraulic fracturing technology has led to tension between hoped-for economic benefits and feared environmental and other costs, with great associated controversy. Studies of how policy can best react to these challenges and how it can balance risk and reward have focused on prescriptive regulatory responses and, to a somewhat lesser extent, voluntary industry best practices. While there is undoubtedly room for improved regulation, innovative tools are relatively understudied. The liability system predates environmental regulation yet still plays an important—and in some senses predominant—role. Changes to that system, including ...

Why Environmental Laws Fail, Jan G. Laitos, Lauren Joseph Wolongevicz 2015 College of William & Mary Law School

Why Environmental Laws Fail, Jan G. Laitos, Lauren Joseph Wolongevicz

William & Mary Environmental Law and Policy Review

Although governments have deployed an array of environmental protection laws, our planet continues to experience unprecedented environmental “crises,” including climate change, resource depletion, species extinction, ecosystem damage, and toxic air-water-land pollution. Despite universal acknowledgment and recognition of these serious environmental issues, and despite a growing list of laws designed to address these issues, the reality is that these adverse Earth-based environmental changes continue, and may even be worsening. Environmental protection laws have often failed because they usually include certain problematic characteristics: they are anthropocentric, in that their goal is to protect and benefit humans, not the environment in which humans ...

An Assessment Of South China Tiger Reintroduction Potential In Hupingshan And Houhe National Nature Reserves, China, Yiyuan Qin, Philip J. Nyhus, Courtney L. Larson, Charles J.W. Carroll, Jeff Muntifering, Thomas D. Dahmer, Lu Jun, Ronald L. Tilson

Philip J. Nyhus

Human-caused biodiversity loss is a global problem, large carnivores are particularly threatened, and the tiger (Panthera tigris) is among the world’s most endangered large carnivores. The South China tiger (Panthera tigris amoyensis) is the most critically endangered tiger subspecies and is considered functionally extinct in the wild. The government of China has expressed its intent to reintroduce a small population of South China tigers into a portion of their historic range as part of a larger goal to recover wild tiger populations in China. This would be the world’s first major tiger reintroduction program. A free-ranging population of ...

Application Of Colloidal Gas Aphron Suspensions Produced From Sapindus Mukorossi For Arsenic Removal From Contaminated Soil, Soumyadeep Mukhopadhyay Dr, Sumona Mukherjee Ms, Mohd Ali Hashim Dr, Bhaskar Sen Gupta Dr

Soumyadeep Mukhopadhyay Dr

Colloidal gas aphron dispersions (CGAs) can be described as a system of microbubbles suspended homogenously in a liquid matrix. This work examines the performance of CGAs in comparison to surfactant solutions for washing low levels of arsenic from an iron rich soil. Sodium Dodecyl Sulfate (SDS) and saponin, a biodegradable surfactant, obtained from Sapindus mukorossi or soapnut fruit were used for generating CGAs and solutions for soil washing. Column washing experiments were performed in down-flow and up flow modes at a soil pH of 5 and 6 using varying concentration of SDS and soapnut solutions as well as CGAs. Soapnut ...

Integrating Hands-On Undergraduate Research In An Applied Spatial Science Senior Level Capstone Course, David Kulhavy, Daniel Unger, I-Kuai Hung, David Douglass

Faculty Publications

A senior within a spatial science Ecological Planning capstone course designed an undergraduate research project to increase his spatial science expertise and to assess the hands-on instruction methodology employed within the Bachelor of Science in Spatial Science program at Stephen F Austin State University. The height of 30 building features estimated remotely with LiDAR data, within the Pictometry remotely sensed web-based interface, and in situ with a laser rangefinder were compared to actual building feature height measurements. A comparison of estimated height with actual height indicated that all three estimation techniques tested were unbiased estimators of height. An ANOVA, conducted ...


Amine-Pillared Nanosheet Adsorbents For Co2 Capture Applications, Hui Jiang 2015 Northeastern University

Amine-Pillared Nanosheet Adsorbents For Co2 Capture Applications, Hui Jiang

Chemical Engineering Master's Theses

Amine-functionalized solid adsorbents have gained attention within the last decade for their application in carbon dioxide capture, due to their many advantages such as low energy cost for regeneration, tunable structure, elimination of corrosion problems, and additional advantages. However, one of the challenges facing this technology is to accomplish both high CO2 capture capacity along with high CO2 diffusion rates concurrently. Current amine-based solid sorbents such as porous materials similar to SBA-15 have large pores diffusion entering molecules; however, the pores become clogged upon amine inclusion.

To meet this challenge, our group's solution involves the creation of ...


Applying The Analytic Hierarchy Process To Oil Sands Environmental Compliance Risk Management, Izak Johannes Roux 2015 Walden University

Applying The Analytic Hierarchy Process To Oil Sands Environmental Compliance Risk Management, Izak Johannes Roux

Dissertations and Doctoral Studies

Oil companies in Alberta, Canada, invested $32 billion on new oil sands projects in 2013. Despite the size of this investment, there is a demonstrable deficiency in the uniformity and understanding of environmental legislation requirements that manifest into increased project compliance risks. This descriptive study developed 2 prioritized lists of environmental regulatory compliance risks and mitigation strategies and used multi-criteria decision theory for its theoretical framework. Information from compiled lists of environmental compliance risks and mitigation strategies was used to generate a specialized pairwise survey, which was piloted by 5 subject matter experts (SMEs). The survey was validated by a ...


Bromide Removal From Surface Waters By Silver Impregnated Activated Carbon, Chen Chen 2015 Clemson University

Bromide Removal From Surface Waters By Silver Impregnated Activated Carbon, Chen Chen

All Theses

Bromide is a precursor of disinfection by-products (DBPs) during potable water treatment, because it causes the formation of brominated DBPs that are more cyto- and geno-toxic than their chlorinated analogues. Due to the potential health risks of DBPs, the United States Environmental Protection Agency (USEPA) has been imposing increasingly stringent regulations for controlling the DBPs. Therefore, removal of bromide ions from source waters becomes critical for controlling the DBPs formation. In my study, it was hypothesized that silver impregnated activated carbon (SIAC) can be a promising adsorbent for bromide removal from water. The main research objectives of this study were ...


Environmental Art, Prior Knowledge About Climate Change, And Carbon Offsets, Julia Blasch, Robert W. Turner 2015 ETH Zurich

Environmental Art, Prior Knowledge About Climate Change, And Carbon Offsets, Julia Blasch, Robert W. Turner

Economics Faculty Working Papers

Using a contingent choice survey of US citizens, we investigate the influence of environmental art on individual willingness to purchase voluntary carbon offsets. In a split-sample experiment, we compare the stated preferences of survey respondents in two different treatment groups to the preferences of a control group. One treatment group is shown photographs that illustrate the impacts of climate change; the other is shown animated images that illustrate wind speeds and patterns for extreme weather events. While individuals seeing the photographs show a higher willingness to purchase voluntary offset than the control group, respondents seeing the animated images seem less ...


Response Of Soil Nitrification To The Veterinary Pharmaceuticals Monensin, Ivermectin And Zinc Bacitracin, Magda A. Konopka 2014 The University of Western Ontario

Response Of Soil Nitrification To The Veterinary Pharmaceuticals Monensin, Ivermectin And Zinc Bacitracin, Magda A. Konopka

University of Western Ontario - Electronic Thesis and Dissertation Repository

Pharmaceutical residues can reach agricultural land through amendment with animal or human waste. Since 2010, a series of replicated plots received annual applications of ivermectin, monensin and zinc bacitracin, either singly or in a mixture, at 0.1 mg/kg and 10 mg/kg concentrations. I collected soil samples before and after the fourth annual application of pharmaceuticals and assayed them for functional changes and amoA gene abundance, a gene needed for ammonia oxidation. In 2013, I exposed the soils to 100 mg/kg in a laboratory experiment which resulted in acceleration of nitrification. Under 10 mg/kg treatments in ...

Land Use Interactions Drive Southwestern Ontario Stream Nutrient Concentrations, Renee L. Lazor

University of Western Ontario - Electronic Thesis and Dissertation Repository

Human activities have transformed the landscape and altered natural habitats through intensive land uses including agriculture and urbanization. Identifying land use drivers of tributary nutrient concentrations and describing the magnitude and direction of their relationship are critical activities to improvement management of water quality in basins draining into the Great Lakes. The overarching goal of my thesis was to quantify the cumulative influence of spatial patterns in land use and land cover on variation of nutrient concentrations in tributaries of the Great Lakes. Biweekly water chemistry samples were collected in 29 streams located in southern Ontario between May and November ...


The Non-Lethal Effects Of Climate Change On The Territoriality Of Lottia Gigantea, Tracey Gunanto, Christina Chavez, Jessica Martinez, William G. Wright 2014 Chapman University

The Non-Lethal Effects Of Climate Change On The Territoriality Of Lottia Gigantea, Tracey Gunanto, Christina Chavez, Jessica Martinez, William G. Wright

Undergraduate Student Research Day Abstracts and Posters

The intertidal zone has been described as ground zero for global warming. Here, the owl limpet, Lottia gigantea, adapted to the cool ocean temperatures, must withstand a few hours of baking sun during day-time low tides. This hardship is predicted to increase in frequency and severity in the future as the globe warms. Our research hypothesized that heat events compromise territorial behavior of L. gigantea. All observations and experiments were performed at Inspiration Point near Newport Beach, California. We measured the natural radiant temperature of tagged limpets during day-time low tides using a field-calibrated infrared “thermogun”. We also experimentally amplified ...

Food Waste Streams At A Campus Dining Hall, Alexandra Cirone, Elena Crouch, Christine Kim, Gomian Konneh

The Last Food Mile Conference

Pilot research was conducted by a team of students in the Politics of Food class at the University of Pennsylvania, with the aim to characterize the different streams of food waste arising from a single dining hall on the university campus. There is little available information about food waste streams at this level of detail. This study builds on the work of a previous group of students, who developed a proposal for an institutionalized food recovery program that Penn Dining and Bon Appétit Management Corporation agreed to put to trial in a single dining hall for the 2014-2015 academic year ...

Topographic Controls On N2o And N2 Efflux In A Temperate Forest, Eric M. Enanga 2014 The University of Western Ontario

Topographic Controls On N2o And N2 Efflux In A Temperate Forest, Eric M. Enanga

University of Western Ontario - Electronic Thesis and Dissertation Repository

The release of greenhouse gases into the atmosphere is becoming an increasingly important problem due to the overwhelming evidence of the relationship between rising greenhouse gas concentrations and increased global temperatures. It is important that we gain a better understanding of the processes controlling the release of N2O, a powerful greenhouse gas. Topographic influences on soil temperature, moisture, reduction-oxidation (redox) potential, dissolved organic carbon, and nitrate conditions, which in turn influence N2O release, were investigated in a natural temperate forest ecosystem in Ontario, Canada. Wetland positions were observed to have the conditions most suited for N ...


Food Waste Composting On A Bahamas Resort: Barriers Encountered And Lessons Learned, Kathleen Sealey 2014 University of Pennsylvania

Food Waste Composting On A Bahamas Resort: Barriers Encountered And Lessons Learned, Kathleen Sealey

The Last Food Mile Conference

The ability for small islands to meet sustainability goals is exacerbated by the costs of transporting goods on, and then, wastes off the islands. At small scales, recycling can be prohibitive and complicated by labor costs; the need to profitably recycle and manage solid waste output from tourism is complicated by scale and available technologies. An on-going, multi-year study documents the amount of solid waste generated on Great Exuma, The Commonwealth of The Bahamas, since 2010 with benchmarking, then limited recycling of food waste generation by an all-inclusive resort, Sandals Emerald Bay. For the island of Exuma, the rapid increase ...
