Using Electrocoagulation To Remove Perfluoroalkyl And Polyfluoroalkyl Substances (Pfas) From Contaminated Water, Amy Yanagida 2020 University of Nebraska-Lincoln

Using Electrocoagulation To Remove Perfluoroalkyl And Polyfluoroalkyl Substances (Pfas) From Contaminated Water, Amy Yanagida

UCARE Research Products

Perfluoroalkyl and Polyfluoroalkyl substances (PFAS) are a family of manmade chemicals that are used to improve the quality of several commercial products by making them resistant to heat, oil, stains, grease and water. Unfortunately, the chemical properties that make PFAS useful from an industrial perspective also make them mobile and recalcitrant once released into the environment. We used electrocoagulation to run a direct current through contaminated water to generate a zinc floc to precipiate PFAS out of water.


Assessment Of The Environmental And Economic Impacts Of Fossil Fuel Subsidies, Evan Cobey 2020 University of Lynchburg

Assessment Of The Environmental And Economic Impacts Of Fossil Fuel Subsidies, Evan Cobey

Undergraduate Theses and Capstone Projects

Renewable sources of energy remove dependence on fossil fuels. When renewable sources are adopted, they reduce damage to the environment from burning fossil fuels. Currently, fossil fuels are cheaper to produce, causing renewable energy to be used less. In the United States, fossil fuels receive heavy subsidies, keeping renewable energy in the periphery. This research explores the environmental and economic effects of subsidizing fossil fuels. Findings include that governments and citizens lose money when fossil fuels are subsidized. While subsidization initially makes them cheaper, they create expenses that are not factored into original costs, such as damage to human health ...


Crude Intentions: Evaluating The Growing Risks Of Arctic Alaskan Oil Production, Eliot Stein 2020 SIT Study Abroad

Crude Intentions: Evaluating The Growing Risks Of Arctic Alaskan Oil Production, Eliot Stein

Independent Study Project (ISP) Collection

The discovery of oil on Alaska’s North Slope in the 1920s began a century of fossil fuel exploration, development, and production in the Arctic region. Alaska became integral to the nation’s growing energy dominance. However, since 1988, oil production on the North Slope has been in steady decline. In 2015, Shell, followed by several other oil majors, terminated their Arctic Alaska operations. This past year, BP made waves by ending six decades of operations in Alaska. Most recently, five of the six major U.S. banks announced they would no longer finance Arctic oil and gas projects. This ...


Indigenous Communities Versus Oil Companies: Identifying Trends In Tactics And Success Of Indigenous-Led Anti-Petroleum Movements In The Ecuadorian Amazon, Ella V. H. Carlson 2020 SIT Study Abroad

Indigenous Communities Versus Oil Companies: Identifying Trends In Tactics And Success Of Indigenous-Led Anti-Petroleum Movements In The Ecuadorian Amazon, Ella V. H. Carlson

Independent Study Project (ISP) Collection

In roughly the last 50 years, the Ecuadorian Amazon has become the epicenter of petroleum production in Ecuador. As oil companies attempt to exploit more and more of the rainforest, they have encroached on indigenous lands, leading to violations of indigenous rights through environmental destruction. As their territories have been invaded, indigenous groups throughout the Amazon have formed movements large and small in resistance to petroleum activities. Scholars have studied select campaigns in the past, but the literature lacks a comparative review of the characteristics of those movements. This paper compiles histories of seven campaigns against petroleum in the Ecuadorian ...

Ecological And Economic Benefits And Risks Of Using Botanical Insecticides In Tanzanian Farms, Lilia Garcia 2020 SIT Study Abroad

Ecological And Economic Benefits And Risks Of Using Botanical Insecticides In Tanzanian Farms, Lilia Garcia

Independent Study Project (ISP) Collection

Insect damage is a major concern for smallholder farmers in developing countries like Tanzania. Synthetic insecticides can tame infestations, however they can be expensive, inaccessible, and their misuse can threaten farmer health and ecological conditions. Botanical insecticides are cheap alternatives to treat infestations while preserving beneficial insects such as pollinators, predators, and parasitoids. This study assesses how both synthetic and botanical insecticides affect beneficial insects, crop yield and profit/costs. This study finds botanical insecticides slightly less harmful towards non-target insects. Botanical insecticides seldomly improve crop yields but usually result in a higher profit/lower cost. Due to high variation ...

Collecting Plant Phenology Data In Imperiled Oregon White Oak Ecosystems: Analysis And Recommendations For Metro, Kirsten Wright

Master of Environmental Management Project Reports

Imperiled Oregon white oak ecosystems are a regional conservation priority due to the rich biodiversity they support, including rare and endemic species such as Oregon state-listed endangered pale larkspur (Delphinium leucophaeum). Previously dominant in the Pacific Northwest, upland prairie and oak woodlands are now under significant threat, with only 2% remaining in the Willamette Valley in small fragments.

Over the past 150 years, conversion to agriculture, urban development and fire suppression have dramatically reduced and degraded Oregon white oak habitat. Climate change has now emerged as an additional threat, causing observable shifts in plant phenology. In fragile oak systems, a ...

Daugherty Water for Food Global Institute: Faculty Publications

This study combines empirical predictive and economics models to estimate the cost of remediation for domestic wells exceeding suggested treatment thresholds for nitrates. A multiple logistic regression model predicted the probability of well contamination by nitrate, and a life cycle costing methodology was used to estimate costs of nitrate contamination in groundwater in two areas of Nebraska. In south-central Nebraska, 37% of wells were estimated to be at risk of exceeding a threshold of 7.5 mg/L as N, and 17% were at risk of exceeding 10 mg/L as N, the legal limit for human consumption in the ...


Recovering From Industrial Overshoot: Thermal Removal Of Atmospheric Co2, Ted von Hippel, Sandra Boetcher, Matthew Traum, Farshid Azadian Ph.D., William MacKunis 2020 Embry-Riddle Aeronautical University

Recovering From Industrial Overshoot: Thermal Removal Of Atmospheric Co2, Ted Von Hippel, Sandra Boetcher, Matthew Traum, Farshid Azadian Ph.D., William Mackunis

Sustainability Conference

Humanity will soon overshoot a safe level of atmospheric CO2, if it hasn't done so already. Countries, industries, and the global economy need to dramatically and quickly alter their behavior and technology to avoid this dangerous overshoot, yet this appears unlikely. Direct Air Capture of CO2 represents an insurance policy for society - a way of removing excess atmospheric CO2. I will present an approach to this problem based on thermal physics that cools cubic kilometers of air to extract CO2 as it sublimates. I propose a combination of an efficient heat exchanger, radiative cooling, and refrigeration, all at industrial ...

Variations In Stream Sediment Microbial Communities Across A Natural Climate Gradient In Eastern Puerto Rico, Victoria Kaptein 2020 The College at Brockport: State University of New York

Variations In Stream Sediment Microbial Communities Across A Natural Climate Gradient In Eastern Puerto Rico, Victoria Kaptein

Environmental Science and Ecology Theses

Six months following the passage of Hurricane Maria across Puerto Rico, water and sediment samples were taken at eight locations along a precipitation gradient to assess the impact of sediment upwelling, organic matter input, and other heavy precipitation-associated influences on water chemistry and microbial populations. Eight sites were broken up into wet (291-440 cm precipitation/yr), dry (140-290 cm precipitation/yr) and reference streams (controls). The hypotheses were as follows: wet environments will be different from dry environments in terms of the number of colony forming units. Furthermore, it is hypothesized that wetter environments should support a greater number of ...
