2017 Nebraska Groundwater Quality Monitoring Report

Nebraska Department of Environmental Quality: Reports

The 2001 Nebraska Legislature passed LB329 (Neb. Rev. Stat. §46-1304) which, in part, directed the Nebraska Department of Environmental Quality (NDEQ) to report on groundwater quality monitoring in Nebraska. Reports have been issued annually since December 2001. The text of the statute applicable to this report follows: “The Department of Environmental Quality shall prepare a report outlining the extent of ground water quality monitoring conducted by natural resources districts during the preceding calendar year. The department shall analyze the data collected for the purpose of determining whether or not ground water quality is degrading or improving and shall present the …

Antibiotics And Antibiotic-Resistant Bacteria In Coastal Plain Streams, Jason Duff

College of Graduate Studies: Theses & Dissertations

Streams across the United States and globally are influenced by environmental contamination, including antibiotics, which enter streams due to widespread use and multiple pathways into the environment. Antibiotics are also likely to enter streams in mixture with other contaminants that alter the effects on aquatic organisms. Furthermore, antibiotic-resistant bacteria enter streams through similar pathways as antibiotics with implications for natural microbial communities. Therefore, understanding the presence and effects of antibiotic-contaminant mixtures and antibiotic-resistant bacteria in streams is important for resource management.

Chapter one describes an experiment that tested the hypothesis that the antibiotic tetracycline (TC) alone influences phytoplankton communities differently …

Assessing Responses Of Betula Papyrifera (Paper Birch) To Climate Variability In A Remnant Population Along The Niobrara River In Nebraska Through Dendroecological And Remote Sensing Techniques, Evan Bumann

School of Natural Resources: Dissertations, Theses, and Student Research

Remnant populations of the boreal species Betula papyrifera, found along north-facing canyons and river banks of the Niobrara River Valley in north-central Nebraska, represent one of the southernmost distributions of the species in North America. Although, the species has persisted in the Great Plains after the Wisconsin Glaciation due to the local topography and microclimatic conditions, canopy dieback has been reported in recent years, which is believed to be attributed to temperature change. Therefore, the goals of this research are to: 1) use dendroecological techniques, or the study of tree rings to assess the responses B. papyrifera to intra- and …

Spatially Biased Dispersal Of Acorns By A Scatter-Hoarding Corvid May Accelerate Passive Restoration Of Oak Habitat On California’S Largest Island, Mario B. Pesendorfer, T. Scott Sillett, Scott A. Morrison

School of Biological Sciences: Faculty Publications

Scatter hoarding by corvids (crows, jays, magpies, and nutcrackers) provides seed dispersal for many large-seeded plants, including oaks and pines. When hoarding seeds, corvids often choose nonrandom locations throughout the landscape, resulting in differential survival of seeds. In the context of habitat restoration, such disproportional storing of seeds in areas suitable for germination and establishment can accelerate expansion and recovery of large-seeded tree populations and their associated ecosystems. Here, we investigate the spatial preferences of island scrub jays Aphelocoma insularis during scatter hoarding of acorns (Quercus spp.) on Santa Cruz Island. We use a large behavioral data set on …

The Last Best Hope: Are Voluntary Conservation Agreements Effective Tools For Protecting Imperiled Species?, Sophie B. Tsairis

Graduate Student Theses, Dissertations, & Professional Papers

Candidate Conservation Agreements with Assurances, or CCAAs, are little known, voluntary conservation agreements that protect imperiled wildlife on private lands. These agreements have emerged over the past decade and have had mixed results in providing adequate protections for candidate species.

Landowners, private industries, state and federal agencies, and environmental nonprofits, are using CCAAs as tools to eliminate the need for an endangered species listing. An Endangered Species Act listing can lead to land-use uncertainty for private landowners and this threat is the main incentive to enroll in a CCAA. When landowners enroll in CCAAs they are agreeing to provide specific …

Understanding Community Character As A Socio-Ecological Framework To Enhance Local-Scale Adaptation: An Interdisciplinary Case Study From Rural Northwest Connecticut, Joanna Wozniak-Brown

Antioch University Dissertations & Theses

Around the world, municipalities are facing new challenges, not the least of which is climate change. This is especially true for rural communities that, for a variety of reasons, will be disproportionately affected by the climatic changes and accompanying policies or programs.

This dissertation, written in manuscript-style, integrates climate change and social-ecological scholarship to address the unique character of rural communities, to communicate the complexity of rural identity through the term "rural character"; and to empower rural communities to incorporate adaptation strategies into their daily municipal operations and planning.

Specifically, this dissertation seeks to answer the following questions: What is …

Coupling Ecological And Social Network Models To Assess “Transmission” And “Contagion” Of An Aquatic Invasive Species, Danielle Haak, Brian D. Fath, Valery E. Forbes, Dustin R. Martin, Kevin L. Pope

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Network analysis is used to address diverse ecological, social, economic, and epidemiological questions, but few efforts have been made to combine these field-specific analyses into interdisciplinary approaches that effectively address how complex systems are interdependent and connected to one another. Identifying and understanding these cross-boundary connections improves natural resource management and promotes proactive, rather than reactive, decisions. This research had two main objectives; first, adapt the framework and approach of infectious disease network modeling so that it may be applied to the socio-ecological problem of spreading aquatic invasive species, and second, use this new coupled model to simulate the spread …

Stop Fighting It Nebraska: Clean Energy Is Here To Stay, Nicholas Underwood

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

The state of Nebraska and more specifically the Nebraska Public Power District has so far shown a surprising reluctance to incorporate clean or renewable sources of power into its portfolio. The state’s reluctance is exemplified in their support for legal challenges to the Clean Power Plan put forth by the Obama Administration. NPPD in particular has decided to stick with coal as its primary fuel source and has even discouraged the construction of natural gas facilities in the state. The power utilities in this state need to develop a modern, clean energy system to avoid being left behind.

The Clean Power Plan And How It Will Change History, Abbie Andersen

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

In a country where 30% of the population still believes that man made climate change is a myth, president Obama has made a daring effort to help fix the damage our country has already inflicted on our planet. By creating The Clean Power Plan (CPP) we’ve taken a step in the right direction as a country. The action that we take to limit our emissions within the next 10 years will likely determine the course of the rest of our existence.

In our current situation humanity has no choice other than to act, and act quickly. We have passed the …

Fossil Fuel Subsides Will Keep The Us In The Stone Age, Alexander Stejskal

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Renewable sources will be the future of energy production for the United States. Clean sources of energy like wind and solar have been the topic of conversation for quite some time, and now they’re starting to show their ability to compete economically with fossil fuels.

Even as renewable sources of energy begin to show their gusto, they are still a part of a relatively new industry and new industries always need a little help getting off the ground. There are some forms of aid being provided for renewable sources of energy, like the production tax credit or PTCs, where the …

Solar, Why Not?, Emily Hergenrader

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Imagine yourself standing outside for an hour wearing a black shirt on a 90-degree day. Now touch your shirt. Notice how warm it is? This warming is due to the sun’s energy. According to Daniel Nocera, a member of the Division of Chemistry at the Massachusetts Institute of Technology, that same heat from one hour of sun exposure is more energy than all of the energy consumed by humans in an entire year.

Energy is one of the hottest topics debated in our world today. Human existence on Earth depends on energy usage and the availability of its consumption. Due …

Why We Should Keep Worrying About The Atomic Bomb, Eric Davis

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

“… the members of the Bulletin of the Atomic Scientists Science and Security Board have looked closely at the world situation and found it highly threatening to humanity—so threatening that the hands of the Doomsday Clock must once again be set at three minutes to midnight, two minutes closer to catastrophe than in 2014…Meanwhile, as they slow the pace of disarmament, the nuclear weapon states have given other strong indications that they are committed to retaining nuclear weapons for the indefinite future” - Bulletin of the Atomic Scientists (2015).

Independent Energy, Ian Hall

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

In the world of energy, an elite selection of the world’s most influential leaders dictates the development of the world. The correlation between petroleum production and global influence is hard to ignore. The world needs energy to move and those with the energy control the movement. Saudi Arabia, Russia, and the US combine to contribute over a third of world oil production. OPEC countries however, dominate the vast energy markets around the world. Well inundated with regional conflict and hostile relations, OPEC countries remain volatile and on top of global energy production.

The energy industry has become extremely productive, fueling …

A Dynamic Power Grid For A Dynamic Age Introducing Les To A Pricing Mechanism That Assesses Demand, And Changes Every Hour, Marvin Christopher Cunningham

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Lets say you knew someone who would buy a whole pizza when they were a little bit hungry, left their sink running when they weren’t using it, maxed out their A/C in their house when they were on vacation, and always kept their stove on just in case they wanted to cook something.

You would probably see this as horribly wasteful, and a terrible drain of money. But every time we pay our power bill, our prices assume we share these wasteful habits. The rate that we pay per kilowatt hour assumes customers are eating the whole pizza, even though …

Les To Increase Fixed Price, Nathan Blazek

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Lincoln Electric System (LES) plans to increase the fixed amount customers pay each month and decrease the rate it charges for each kWh used.

This shift is claimed to be revenue neutral for LES. But for customers, it means they’ll save less money by turning off lights and buying more efficient appliances.

This policy is a sly and deliberate stab at ongoing conservation efforts. The decreased kilowatt pricing will give customers the perception that it is relatively unnecessary to decrease electricity usage if they are already paying a high price to initially have it. This new policy will even further …

Is Nebraska Really “The Good Life”?, Sarah Porath

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

For anyone who has ever lived in Nebraska, you know the state is filled with people who resist change. Nebraska is “The Good Life.” Any adjustments or modifications that could disrupt the lifestyle are not welcomed. The people who are elected into office clearly reflect this type of mindset.

It is time for Nebraska to get outside of their comfort zone. We need to move from the good life to the great, healthy, and progressive life by developing a state-wide Energy Efficiency Resource Standard or Goal.

20 states have Mandated Statewide Energy Efficiency Resource Standards and 8 states have Goals …

Fracking Chill, Nick Nardone

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Hydraulic Fracturing or commonly known as fracking has caused a big boom in the oil and gas industry making it easier for us to extract oil and gas from the ground, but has serious side effects that as they cause harm to us and our environment. We should slow or stop fracking at once if we want a clean and healthy environment to live in.

Fracking has become widely popular in the last decade and has brought us benefits on the oil and gas side and with little lack of information and support it has been difficult to put restrictions …

The Great Plains: America’S Carbon Vault, William Davidson

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

As a nation we are starting a race against climate change, a competitor who has had a very long head start and only plans on picking up the pace. The Clean Power Plan has laid a blueprint to lower carbon emissions from fossil fuel burning power plants nationwide, a crucial step in recovering from decades of pollution. Meeting these goals will take years and greenhouse gasses will continue to accumulate throughout the process. Efforts beyond the scope of this plan must also be made in order to prevent emissions from sources not specifically addressed, namely sources of carbon that cannot …

Calculating The Methan-Matics Of Our Future, Victoria Salinas

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

In the first two decades after its release, methane, a green house gas, is 84 times more potent than carbon dioxide. Historically, atmospheric concentrations of methane remained fairly stable at around 750 ppb, significantly less than today’s levels of 1,800 ppb. Unfortunately, agricultural activity accounts for about one-fifth of total global greenhouse gas emissions, while the current production of ruminants contributes nearly 80% of these emissions due to their large populations, body size and appetites, and the anaerobic microbial fermentation that occurs during digestion. Because of methane’s severe impact on the climate, methane emissions, specifically due to the production of …

Willingness To Pay Today For A Cleaner Tomorrow, Yukihira Naoe

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

To a ten year old boy on a tedious trip across the country side, few views are more fascinating than a wind farm. Massive turbines spin slowly as if to emphasize their preposterous size and magnificence. In an era where increasing global attention is brought to climate change, renewable energy is carving its way into the minds of billions. This once free roadside attraction is now something that in the near future, we must pay and patronize, and this is where my literature begins, how willing are we to pay for renewable energy? Are you willing to pay to give …

Flight of the Freshwater Fish

The Hudson River provides for millions of people as a path for commercial and private transportation, a source of food and energy, and perhaps most importantly for many living in the tri-state area as a destination for recreation and relaxation. The most overlooked feature of the river is how the wildlife shows clear signs of a changing climate and rapid environmental response to the impacts of global warming on the river.

Entire populations of fish species in the lower Hudson have been forced to leave the river …

Getting Road Expansion On The Right Track: A Framework For Smart Infrastructure Planning In The Mekong, Andrew Balmford, Huafeng Chen, Ben Phalan, Mingcheng Wang, Christine S. O'Connell, Cath Tayleur, Jianchu Xu

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

The current unprecedented expansion of infrastructure promises to enhance human wellbeing but risks causing substantial harm to natural ecosystems and the benefits they provide for people. A framework for systematically and proactively identifying the likely benefits and costs of such developments is badly needed. Here, we develop and test at the subregional scale a recently proposed global scheme for comparing the potential gains from new roads for food production with their likely impact on biodiversity and ecosystem services. Working in the Greater Mekong—an exceptionally biodiverse subregion undergoing rapid development—we combined maps of isolation from urban centres, yield gaps, and the …

Modern Fair-Weather And Storm Sediment Transport Around Ship Island, Mississippi: Implications For Coastal Habitats And Restoration Efforts, Eve Rettew Eisemann

Master's Theses

The Mississippi – Alabama barrier island chain is experiencing accelerated sea level rise, decreased sediment supply, and frequent hurricane impacts. These three factors drive unprecedented rates of morphology change and ecosystem reduction. All islands in the chain have experienced land loss on the order of hectares per year since records began in the 1840s. In 1969, Hurricane Camille impacted as a Category 5, breaching Ship Island, and significantly reduced viable seagrass habitat. Hurricane Katrina impacted as a Category 3 in 2005, further widening Camille Cut. To better understand the sustainability of these important islands and the ecosystems they support, sediment …

Predicting Post-Fire Change In West Virginia, Usa From Remotely-Sensed Data, Michael Strager P. Strager, Melissa Thomas-Van Gundy, Aaron E. Maxwell

Journal of Geospatial Applications in Natural Resources

Prescribed burning is used in West Virginia, USA to return the important disturbance process of fire to oak and oak-pine forests. Species composition and structure are often the main goals for re-establishing fire with less emphasis on fuel reduction or reducing catastrophic wildfire. In planning prescribed fires land managers could benefit from the ability to predict mortality to overstory trees. In this study, wildfires and prescribed fires in West Virginia were examined to determine if specific landscape and terrain characteristics were associated with patches of high/moderate post-fire change. Using the ensemble machine learning approach of Random Forest, we determined that …

Panarchy Use In Environmental Science For Risk And Resilience Planning, David G. Angeler, Craig R. Allen, Ahjond S. Garmestani, Lance H. Gunderson, Igor Linkov

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Environmental sciences have an important role in informing sustainable management of built environments by providing insights about the drivers and potentially negative impacts of global environmental change. Here, we discuss panarchy theory, a multi-scale hierarchical concept that accounts for the dynamism of complex socio-ecological systems, especially for those systems with strong cross-scale feedbacks. The idea of panarchy underlies much of system resilience, focusing on how systems respond to known and unknown threats. Panarchy theory can provide a framework for qualitative and quantitative research and application in the environmental sciences, which can in turn inform the ongoing efforts in sociotechnical resilience …
