2018 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 …

Application Of Molecular Pathology Techniques To Understand Mechanisms Of Disease In Smallmouth Bass, Heather Leigh Walsh

Graduate Theses, Dissertations, and Problem Reports (ETD)

In the Chesapeake Bay drainage, smallmouth bass Micropterus dolomieu are used as an indicator species of estrogenic contaminant exposure and have been implicated in fish kills and disease since 2005. In the Potomac River drainage, adult smallmouth bass have experienced mortality and disease and males have a high prevalence of intersex (testicular oocytes). Conversely, in the Susquehanna River drainage mortalities and disease of young-of-the-year smallmouth bass (YOY SMB) have occurred and resulted in a population shift to older and larger fish. The exact cause of these events remains unknown; however, factors such as poor water quality, contaminants, pathogens and parasites, …

Efficacy Of Herbivore Exclusion On Planted Tree Seedling Vitality On A Reclaimed Surface Mine In Eastern Kentucky, Zachary J. Hackworth

Theses and Dissertations--Forestry and Natural Resources

Conventional Appalachian surface-mine reclamation techniques repress natural forest regeneration, and tree plantings are often necessary for reforestation. Reclaimed Appalachian surface mines harbor a suite of mammal herbivores that forage on recently planted seedlings. Anecdotal reports across Appalachia have implicated herbivory in the hindrance and failure of reforestation efforts, yet empirical evaluation of herbivory impacts on planted seedling vitality in this region remains relatively uninitiated. First growing-season survival, height growth, and mammal herbivory damage of black locust (Robinia pseudoacacia L.), shortleaf pine (Pinus echinata Mill.), and white oak (Quercus alba L.) are presented in response to varying intensities …

Predicting Invasive Carp Habitat Suitability In The Minnesota River, Minnesota, Melissa Oubre

All Graduate Theses, Dissertations, and Other Capstone Projects

Since the 1980's invasive carp have been expanding their range northward up the Mississippi River. Consisting of four species, grass carp (Ctenophaygodon idella), silver carp (Hypophthalmichthys molitrix), bighead carp (H. nobilis), and black carp (Mylopharyngodon piceus), these fish have the potential to naturalize and expand into large Mississippi River tributaries like the Minnesota River (MNR). Thus, understanding the likelihood of naturalization in these tributaries is vital in guiding prevention or mitigation efforts. This study evaluates the environmental suitability of the Minnesota River, the largest tributary to the Mississippi in Minnesota, for invasive carp. Environmental suitability for invasive carp is modeled …

Geomorphic Consequences Of Hydroelectricity And Transportation Development Near Celilo Falls, Lower Mid-Columbia River, Washington, Noah I. Oliver

All Master's Theses

Along the Columbia River, hundreds of miles of transportation infrastructure and over sixty hydroelectric dams have been constructed. This altered a rich cultural landscape with evidence of 10,000 years of continuous occupation. Researchers have attempted to understand the impacts of anthropogenic factors on the Columbia River, focusing on the riverine environment. However, the effect of transportation and hydroelectricity developments to eolian landforms on the floodplains and adjoining slopes have not been studied. Focusing on 2,800 acres near Celilo Falls, this study 1) establishes a baseline condition of eolian landforms from 1805 to 1900; 2) conducts an air photo increment analysis …

The Fossil Fuel Energy Industry Vs. The Endangered Species Act, Cody Willnerd

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

It was several weeks ago that the Congressional Republicans made a push to reform the landmark Endangered Species Act to make it more friendly to landowners and fossil fuel industries. They would do this by releasing species earlier on the ESA list than before and instead focus on species that are in the greatest of need of attention. The reform would also have agencies focus on the economic costs to deny listings of species, require the agency to listen towards states concerns, and limit payouts for attorney fees in ESA litigations. This would be incredibly damaging to many species that …

Building Our Way To A Better Future, Brad Shaner

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

The potential demolishing of the Clean Power Plan by the federal government in early October is looking like a losing fight in our war against carbon emissions at one of the biggest sources of these emissions. But we can continue to fight in this war and make an even bigger impact by focusing our efforts on the most ordinary and consistent thing in our modern lives; the buildings we live and work in. Some would say that high efficiency or green buildings are a commodity that only the wealthy individuals or businesses can achieve, but this doesn’t have to be …

A Forgotten Resource: Thorium, Daniel Rico

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

The year is 1945, the morning of August 6^th, 8:16am to be exact. The United States just dropped the world’s first militarized atomic weapon on Hiroshima, Japan. With this singular act the world virtually witnessed the end of its second world war, the birth of warfare like never before, and the foreseeable death of nuclear power. With this act an aura of negativity and destruction accompanied the word nuclear that it would likely never be rid of despite untapped high grade energy potential that can outweigh its military application. The bomb dropped on Hiroshima was composed of 64 …

Eliminate The Carbon Externality, Connor Mcfayden

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

Before we do anything else, let’s establish two things: the global climate is changing at an alarming rate and the primary cause is human CO2 emissions. There is a worldwide scientific consensus on this fact. Even our own government, despite a remarkably vocal minority, has confirmed this. A report released this year by 13 government agencies identifies humans as the primary cause of global climate change and links this phenomenon to rising sea levels, increased incidence of droughts and floods, and the intensification of large storms. These events are the result of the carbon externality, the social costs of emissions …

Cardboard Ban Is An Investment Opportunity, John Schwaninger

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

Lincoln’s cardboard ban was a hot topic in 2016, but 2017 has shifted focus to the city’s recycling education contract. Gone is discussion of Mayor Chris Beutler’s failed, revived and ultimately victorious struggle to reform Lincoln’s recycling program. In its place, an air of financial discomfort stagnates over the city’s already troubled budget.

The cardboard ban will take effect April 2018. The recycling education program was drafted in part to support the ban by educating households about recycling drop-off locations and sorting requirements. However, the recycling education contract’s $850,000 cost raised eyebrows, undermining Beutler’s earlier effort.

The recycling education contract’s …

Lithium-Ion Batteries: It’S Not About The Lithium, Jace Kranau

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

Malnourished children and tired men chip away with ancient tools at Cobalt-containing rock for you to have the next best electronic device. The impoverished, artisanal workers of the Democratic Republic of Congo (DRC) supply up to 25 percent of global Cobalt according to The Washington Post. The battery manufacturers don’t care. Their dominant thought is profit.

Artisanal workers are paid between two and three U.S. dollars a day. “We are suffering. And our suffering is for what?”, 29-year-old digger, Nathan Muyamba, told The Post.

The batteries in phones, laptops and for some, their cars, contain Lithium, Cobalt, Nickel …

Crop Productivity In The Ag Belt On Borrowed Time, Logan Winters

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

Most people by now have heard the terms “climate change” and global warming. Many acknowledge that it’s a problem, but they may not know how it can impact them directly. This is especially true for those living in the middle of the country, because most of the media attention goes to the coastal impacts of climate change. While putting adequate focus on the coastal impacts is a good start, since the most widespread and severe impacts will be coastal, but there needs to be more talk and discussion about the future impacts over the middle of the country. One big …

Energy Star Tax Holiday Simply Advertising Gimmick, Lauren Klaasmeyer

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

In January of this year, Senator Harr introduced Legislative Bill 325. From 12:01 A.M. on the first Friday of October through midnight of the first Sunday, all Energy Star products less than $1500 will be exempt from sales and use taxes. The special interest group, Nebraska Retail Federation, proposed the idea to Senator Harr. There was no move to advance the bill last session, so it could be brought back up this coming session or amended to another bill. When speaking with people at the capitol, it was said that the main reason it was not advanced was because of …

How Innovative Companies Gain From A Cap And Trade Agreement, Lucian Montgomery

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

The purpose of both a cap and trade agreement and a carbon tax is to reduce emissions by setting a price on carbon. However, that is where the similarities end.

A cap and trade agreement gives a certain amount of allowances to each company that adds up to an emissions cap, allows companies to trade them. Companies only pay for carbon emissions if they produce more than the amount of allowances they are given, either by paying penalties to the government, or by buying more allowances from other companies. This creates a market for allowances, and based on demand, sets …

The Tax That Will Actually Do Something Is Not In The Current Bill, Steven Kirchner

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

If we are going to be talking about tax reform, we should be talking about solutions that will actually solve a problem. The combustion of fossil fuels has much more than environmental implications. Burning fossil fuels is a blatant catastrophe for our entire economic system. The current American energy market is entirely reliant on fossil fuels (coal, oil, and natural gas). Negative externalities have flooded the American economic system because of the combustion of fossil fuels. A negative externality is a cost that indirectly affects someone outside of the economic transaction. That third party entity must bear the burden of …

Gmo Regulations Are Killing Biofuels, Megan Franklin

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

Progress in creating profitable biofuels is being slowed down by strict regulations on genetically engineered (GE) crops (aka GMOs). Setbacks that biofuels face can be addressed with genetic engineering. However, public pushback and regulations make it extremely difficult to implement solutions. We should have more lenient regulations on GE crops so that we can speed up the progress of improving biofuels.

A genetically engineered crop is one that has DNA from a different species inserted into its own DNA. As a result from GE crop benefits, CO2 emissions were reduced by 26.7 billion kg in 2012, and poverty was alleviated …

Palm Oil: The Hidden Costs, Rachel Goehring

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

The growing demand for palm oil generates tens of billions of dollars in revenue and employs millions in Southeast Asian countries. The story is that conserving the rainforests from palm oil production puts this economy at risk, but only because the current formula does not account for the externalities of deforestation.

Recent Increase In Deadly Storms, Westin Longacre

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

These last few years have hit us with some devastating storms that continue to wreck havoc on our earth. We have been hit with multiple storms that are so strong that they are predicted to happen every 50 years, so is God punishing us? Or do we have something to do with this? This issue should be a huge concern to us because who knows how many more of these devastating storms we can handle. When looking at why these tragic storms are happening more frequently the main factor that is leading to these events is the increase in atmospheric …

Anaerobic Digestion In Nebraska, Anthony Leapley

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

Climate change is a global crisis that can be fought by all locally. Nebraska is my home, and it’s one of nine states in the U.S. in which cows outnumber humans. Statistically, there are three cows for every person (1,868,516 humans to 6,150,000 cows). While we have fewer humans than cows, it’s not hard to understand that we rank very low in CO2 emissions when ranking all states in the country. However, our emission of the more potent greenhouse gas CH4, or methane, is significantly higher. Methane is released by cows via gas and manure, and it’s causing serious implications …

Wind Is Nebraska’S Future, With Or Without The Clean Power Plan, Megan Pamperin

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

The Clean Power Plan was issued in October 2015. President Trump called for a review of the plan this March and on October 16^th, 2017 the EPA released a proposal to repeal it. The Clean Power Plan would have reduced Nebraska’s state emissions to 22,250,000 tons of carbon dioxide by 2024, down by about 5 million tons compared to 2012 emissions.¹ The new projection for 2020 without the plan is 34 million tons of CO₂ emitted.

Coal and other fossil fuel energy sources are the main culprits of these carbon emissions, and here in Nebraska coal …

Recycling Clean Energy, Amanda Vaughn

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

Nuclear energy is one of the cleanest sources of energy available. It does not produce carbon dioxide as the beta decay of Uranium is an exothermic spontaneous process that produces helium. Unfortunately, nuclear waste storage is a large problem in the United States, the cost of maintaining the waste storage facilities alone is 46.7 billion dollars. There is the constant threat of leaks and contaminated water leaking into drinking supplies. Then there is the danger of the current geological storage tanks lasting longer than humanity and spoiling the future environment as current nuclear waste takes millions of years to decompose …

Fossil Fuel Subsidies In America, Jackson Cutsor

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

Two of the most controversial topics in American politics today are climate change and the federal budget. Subsidies for energy generation fit into both categories.

Subsidies given to the energy industry artificially decrease the price of energy and electricity. Low energy prices help stimulate the market, however, the negative externalities like the social cost of carbon and political corruption are not taken into consideration.

Subsidies can come in many forms including: failure to impose external costs, tax breaks, and low interest loans. Even without imposing the social cost of carbon a removal of fossil fuel energy subsidies can have a …

Translating Statistical Species-Habitat Models To Interactive Decision Support Tools, Lyndsie S. Wszola, Victoria L. Simonsen, Erica F. Stuber, Caitlyn R. Gillespie, Lindsey N. Messinger, Karie L. Decker, Jeffrey J. Lusk, Christopher F. Jorgensen, Andrew A. Bishop, Joseph J. Fontaine

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Understanding species-habitat relationships is vital to successful conservation, but the tools used to communicate species-habitat relationships are often poorly suited to the information needs of conservation practitioners. Here we present a novel method for translating a statistical species-habitat model, a regression analysis relating ring-necked pheasant abundance to landcover, into an interactive online tool. The Pheasant Habitat Simulator combines the analytical power of the R programming environment with the user-friendly Shiny web interface to create an online platform in which wildlife professionals can explore the effects of variation in local landcover on relative pheasant habitat suitability within spatial scales relevant to …

Assessing Preservation Priorities Of Caves And Karst Areas Using The Frequency Of Endemic Cave-Dwelling Species, Eugen Nitzu, Marius Vlaicu, Andrei Giurginca, Ioana N. Meleg, Ionut Popa, Augustin Nae, Ştefan Baba

International Journal of Speleology

Endemic and rare species as bioindicators of habitat vulnerability were used to develop protection and management plans for biotope prioritization (mainly islands habitats, lava tubes or groundwaters). Due to their narrow distribution, the endemic species (species confined to a restricted geographic area) are more susceptible to ecological disequilibrium and habitat loss than the widespread ones. Consequently, endemics become endangered in the context of ecological disturbance caused by anthropogenic pressure, making them suitable candidates to assess environmental preservation needs. Taking into consideration that most of the stygobitic and troglobitic species are endemic and confined to specific karst areas, based on their …

Assessing the Periodic Groundwater Flow Conditions of a Perched Aquifer System in the Daniel Boone National Forest

Ethan Sweet and Jonathan Malzone

Eastern Kentucky University, Department of Geosciences

Natural ephemeral wetlands situated among the ridge-tops in the Daniel Boone National Forest serve as reservoirs that recharge a shallow groundwater system. Unique interactions between surface and groundwater in these isolated systems provide substantial support for the native ecosystem, serving as a breeding ground for amphibians and as source water for vegetation—especially in periods of drought. Currently it is not understood how groundwater could provide regional biodiversity, a drought buffer, or a …

Counting Crabs: Assessment Of Mangrove Crab Diversity And Density Among Three Sites In Ushongo, Tanzania, Clarasophia Gust

Independent Study Project (ISP) Collection

This study assessed the density and diversity of crabs across three mangrove forest zones in Ushongo, Tanzania. The aim was to understand variance in the composition and distribution of mangrove crabs in relation to mangrove tree composition gradients in the area. Sites were measured using a 200m line transect and 40-plot method. Data was also collected from a sand beach habitat to compare to the diversity and distribution of mangrove habitats. Diversity was analyzed using Simpson’s Index of Diversity and an ANOVA test on the average number of species found per plot in each site. Density was analyzed using an …

Effects Of A Prescribed Burn On The Adult Butterfly Assemblage Of A Coastal Grassland, J. Nicole Desha, Joseph Colbert, Kimberly M. Andrews, Scott Coleman, C. Tate Holbrook

Georgia Journal of Science

Coastal grasslands are globally threatened by development and natural succession. In the southeastern United States, these increasingly rare ecosystems are being managed using prescribed fire, but ecological responses to fire management are largely unknown, particularly among nontargeted species. We tested for short-term effects of controlled burning on the abundance and species richness of adult butterflies, which utilize coastal grasslands for nectaring resources and as migratory stopover sites. In February 2015, four plots of coastal grassland on Little St. Simons Island, GA were burned and paired with unburned (control) plots of equal size. Throughout the following summer-fall flight season, we conducted …

Improving The Accuracy For The Long-Term Hydrologic Impact Assessment (L-Thia) Model, Anqi Zhang, Lawrence Theller, Bernard A. Engel

The Summer Undergraduate Research Fellowship (SURF) Symposium

Urbanization increases runoff by changing land use types from less impervious to impervious covers. Improving the accuracy of a runoff assessment model, the Long-Term Hydrologic Impact Assessment (L-THIA) Model, can help us to better evaluate the potential uses of Low Impact Development (LID) practices aimed at reducing runoff, as well as to identify appropriate runoff and water quality mitigation methods. Several versions of the model have been built over time, and inconsistencies have been introduced between the models. To improve the accuracy and consistency of the model, the equations and parameters (primarily curve numbers in the case of this model) …

Acoustic Signatures Of Habitat Types In The Miombo Woodlands Of Western Tanzania, Sheryl Vanessa Amorocho, Dante Francomano, Kristen M. Bellisario, Ben Gottesman, Bryan C. Pijanowski

The Summer Undergraduate Research Fellowship (SURF) Symposium

The Miombo Woodlands of Tanzania comprise several habitat types that are home to a great number of flora and fauna. Understanding their responses to increasing human disturbance is important for conservation, especially in places where people depend so directly on their local ecosystem services to survive. Soundscapes are a powerful approach to study complex biomes undergoing change. The sounds emitted by soniferous fauna characterize the acoustic profile of the landscapes they inhabit such that habitats with the highest acoustic abundance are considered as the most diverse and possibly more ecologically resilient. However, acoustic variability within similar habitat types may pose …
