An Assessment Of Disinfection-Related Water Chemistry At Public Pools And Spas In Louisville, Kentucky, Thomas Gerding, Tim Wilder, Jason W. Marion
An Assessment Of Disinfection-Related Water Chemistry At Public Pools And Spas In Louisville, Kentucky, Thomas Gerding, Tim Wilder, Jason W. Marion
EKU Faculty and Staff Scholarship
The growth in the number of pools to more than 7.4 million in the U.S. has been accompanied by a rise in recreational water illnesses (RWIs). Effective pool management, though, can mitigate RWI risks. Inadequate management presumably occurs more frequently where training is less formalized and/or pool operation is a minor aspect of the job of the responsible pool manager(s). During summer 2018, weekly evaluations were performed at public venues in Louisville, Kentucky. Disinfectant levels and other items were monitored and compared with venue-specific (pool or spa) criteria. Among 1,312 venue surveys, 1,173 (89.4%) met criteria and 139 (10.6%) did …

Incorporating Characteristics Of Gene Drive Engineered Ae. Aegypti As Methods To Reduce Dengue And Zika Virus Into The Bayesian Network – Relativ Esian Network – Relative Risk Model, Using P E Risk Model, Using Ponce, Puer Once, Puerto Rico As A Case Study, Steven R. Eikenbary
Institute of Environmental Toxicology & Chemistry Publications
This study proposes the use of the Bayesian network relative risk model (BN-RRM) to estimate the risk associated with the release of gene drives as vectors to control disease, using Ponce, Puerto Rico as a case study. Bayesian networks are an appropriate risk assessment tool for quantitatively and probabilistically examining complex systems involving multiple stressors acting on multiple endpoints in a wide variety of situations. The emerging field of synthetic biology has the capacity to drastically alter ecological systems with the use of gene drive engineered organisms as a method to alter population dynamics. The purpose of the release of …

Vegetation is an important ecological component of offshore islands in the Arabian Gulf (AG), which maintains long-term resilience of these islands. This is achieved by influencing sediment retention and moisture acquisition via condensation during periods of high humidity and by providing a variety of microhabitats for island fauna. The resilience of offshore islands’ ecosystems in the Saudi waters is important because they host the largest number of nesting hawksbill and green turtles in the AG. This study defines the characteristics and the long-term trends in vegetation cover of the offshore islands used by sea turtles as nesting grounds in the …
Microplastics In Mississippi River Fishes: A Watershed Approach, Ahmed Gad
Microplastics In Mississippi River Fishes: A Watershed Approach, Ahmed Gad
LSU Master's Theses
Microplastics are plastic particles less than 5mm that come from different sources, such as industrial products, cosmetics, and the breakdown of the macroplastics. Microplastics derive from terrestrial sources but concentrate in flowing freshwaters where they may enter aquatic food webs. The northern Gulf of Mexico has shown very high microplastic concentrations, which are assumed to be sourced from the Mississippi River and its watershed. This study seeks to study microplastics in fish in the Mississippi River and the Gulf of Mexico. Fish stomachs and intestines from fish underwent chemical digestion, filtration, and microplastics identification and enumeration through FT-IR spectrometry. Chapter …

There Must Be Something In The Water: A Comparative Study Of Ground Water Contamination In The U.S.A. And Canada, Kathleen Spooner
There Must Be Something In The Water: A Comparative Study Of Ground Water Contamination In The U.S.A. And Canada, Kathleen Spooner
Honors Theses
The regions of Nova Scotia and New Hampshire are naturally susceptible to arsenic water contamination due to their geological makeup. These locations are relatively rural, with many of their citizens reporting low incomes and lacking education, the majority of which are unaware of the risk of arsenic poisoning. There is also a high dependency on private wells which are not regulated in terms of water quality under federal law in both countries. Arsenic water pollution is undetectable as it is both odorless and tasteless and potentially very dangerous, and therefore water testing must be performed on wells, which is currently …
A Comparison Of Tribal Sovereignty, Self-Determination, And Environmental Justice At The Epa’S Onondaga Lake And Tar Creek Superfund Sites, Thomas Clark
Dissertations, Theses, and Capstone Projects
The Environmental Protection Agency’s Superfund program mandates that Native American tribes are afforded the same treatment as states in the implementation of environmental remediation projects; however, the degree of coordination and consultation between the EPA and sovereign tribal governments varies widely between sites. Two of the Superfund program’s highest profile sites with Native American interest, northeast Oklahoma’s Tar Creek and central New York’s Onondaga Lake, are characterized by such a disparity in tribal participation. While Oklahoma’s Quapaw Tribe would ultimately enter into a number of cooperative agreements with the EPA for direct control over remedial projects, New York’s Onondaga Nation …
Does Updating Natural Hazard Maps To Reflect Best Practices Increase Viewer Comprehension Of Risk?, Carson C. Macpherson-Krutsky, Brittany D. Brand, Michael K. Lindell
Does Updating Natural Hazard Maps To Reflect Best Practices Increase Viewer Comprehension Of Risk?, Carson C. Macpherson-Krutsky, Brittany D. Brand, Michael K. Lindell
Geosciences Faculty Publications and Presentations
In this study, we examine whether updating an interactive hazard map using recommendations from the literature improves user map comprehension. Analyses of experimental data collected from 75 university students revealed that map comprehension scores were not significantly better for those who viewed a “best practices” map compared to those who viewed an existing version. This may be because the existing map was itself better than most other interactive maps. Additionally, we found map comprehension levels to have significant positive relationships with objective tests, but not self-reported measures of spatial ability. Moreover, self-reported spatial ability had statistically significant, but only moderately …
Geospatial Applications To Mitigate Concentrated Animal Feeding Operations From Impacting Surface Water Resources, Elias Rex
Electronic Theses, Projects, and Dissertations
Concentrated Animal Feeding Operations (CAFOs) offer the ability to meet the rising demands of population growth by housing large amounts of livestock on relatively small areas of land, using medication to accelerate their maturation, and reusing waste products as fertilizers. However, there is a growing abundance of literature related to land use configurations and their effects on water resources, many of which highlight agriculture as a primary contributor of nutrients and fecal bacteria found in surrounding water resources. The purpose of this study is to advance the current knowledge surrounding CAFO land-use and its effect on tributaries within the Cape …
Storm Surges In The Bohai Sea: The Role Of Waves And Tides, Yuanyi Li, Huan Feng, Guillaume Vigouroux, Dekui Yuan, Guangyu Zhang, Xiaodi Ma, Kun Lei
Storm Surges In The Bohai Sea: The Role Of Waves And Tides, Yuanyi Li, Huan Feng, Guillaume Vigouroux, Dekui Yuan, Guangyu Zhang, Xiaodi Ma, Kun Lei
Department of Earth and Environmental Studies Faculty Scholarship and Creative Works
A storm surge is a complex phenomenon in which waves, tide and current interact. Even though wind is the predominant force driving the surge, waves and tidal phase are also important factors that influence the mass and momentum transport during the surge. Devastating storm surges often occur in the Bohai Sea, a semi-enclosed shallow sea in North China, due to extreme storms. However, the effects of waves on storm surges in the Bohai Sea have not been quantified and the mechanisms responsible for the higher surges that affect part of the Bohai Sea have not been thoroughly studied. In this …

La Habana: A History Of Society, Livelihood, Movement, And Land Use On The Iquitos-Nauta Highway, Katie Brown
Undergraduate Honors Theses
With increasing infrastructural projects and land titling in the Peruvian Amazon, many changes are occurring within small roadside communities. In this case study, we investigate how these changes impact livelihoods, land use, travel patterns, and social relations within the broader concepts of development, privatization of land, and commodification of nature. Specifically we focus on the caserío La Habana situated on the Iquitos-Nauta highway in the Loreto region of Peru. Semi-formal interviews and ethnographic methods were conducted to gather information on social organization, history of the community, land use practices, migration patterns, opinions on the road, and livelihood strategies. After data …

Globally, our knowledge on lake fisheries is still limited despite their importance to food security and livelihoods. Here we show that fish catches can respond either positively or negatively to climate and land-use changes, by analyzing time-series data (1970–2014) for 31 lakes across five continents. We find that effects of a climate or land-use driver (e.g., air temperature) on lake environment could be relatively consistent in directions, but consequential changes in a lake-environmental factor (e.g., water temperature) could result in either increases or decreases in fish catch in a given lake. A subsequent correlation analysis indicates that reductions in fish …
Effects Of Land Use On Riparian Corridors In Sonoma County, Marina Davies
Effects Of Land Use On Riparian Corridors In Sonoma County, Marina Davies
Master's Projects and Capstones
Riparian corridor protection through zoning ordinances is a common best management practice to protect riparian ecosystems and function. These zoning ordinances protect riparian ecosystems by establishing setback distances where land use activities are prohibited. While management of protected riparian corridors are widely studied, recommendations for riparian corridor width vary and are often site specific. The variability of corridor widths presents a challenge to riparian corridor implementation, in addition to balancing economic needs with natural resource protection. This study evaluates the effects of land use on riparian corridors and compares the Riparian Corridor Combining Zone ordinance in Sonoma County to other …
Updating The Electronics Cycle: Improving Us E-Waste Management Practices, Martin Cooper
Updating The Electronics Cycle: Improving Us E-Waste Management Practices, Martin Cooper
Master's Projects and Capstones
The United States is one of the largest producers of electronic waste (e-waste), partly due to a lack of federal legislation to regulate e-waste disposal and transport. Increased collection, recycling, and reuse of electronics can reduce pollution from hazardous metals and chemicals found in e-waste, lower the carbon footprint of the electronics industry, and protect the health of workers in the global waste management sector. This paper examines case studies of e-waste management strategies in European Union member nations and US states, and identifies ways to integrate those strategies in US federal and state policy. This paper finds that extended …

Year-long Analysis of the Water Quality of White Horn Brook
Sponsor: Thomas Boving (Geological Sciences)
Water is the foundation for all life on earth and is the most vital resource on this planet. Despite this, oceans and waterways all over the world are being polluted and exploited in ways detrimental to their fundamental hydrologic functions. For instance, excess nitrate levels can lead to eutrophication which gives rise to harmful algae blooms. Low pH can cause the breakdown of CaCO3 exoskeletons of organisms, such mollusks. High temperature variations are major stressors to living things and can cause …
Downstream Survival Of Total Bacteria, Escherichia Coli And Salmonella Spp. In Sinking Creek And Evaluation Of The Effectiveness Of The Implemented Constructed Wetland, Blaire Brooks
Undergraduate Honors Theses
Access to good quality, pathogen-free water is a necessity for human life. Pathogencontaminated water poses a threat to human health, and steps must be taken to minimize that risk using remediation techniques, such as constructed wetlands. Sinking Creek is a tributary of the Watauga River that was placed on the 2016 303(d) list published by the Tennessee Department of Environment and Conservation due to the presence of Escherichia coli. Because of this impairment, a constructed wetland was placed in Sinking Creek to decrease the downstream transport of pathogens. Knowing this, three primary goals were made for this experiment. The first …

Tri-State Mining District, Ecological System, And Human Health: Systematic Literature Review Analysis, Jihyun Jane Min
Posters
Objective: Although extensive research exists on corrosive environments in the Tri-State Mining District (TSMD), there has been a lack of research on how such harmful effects in the TSMD could affect residents living in those areas. However, quite recently, such research regarding relationships between the health conditions of low-income residents and toxic elements in TSDM began to grow. Therefore, the increase of empirical studies means greater complexity of the findings that require a more intricate understanding.
Methods: To meet the necessity of the study, this research was conducted by an extensive systematic review of the literature on the harmful effects …
An Analysis Of Groundwater Quality As Sampling Networks Age: The Gaps In Groundwater Monitoring, Angela Leone
An Analysis Of Groundwater Quality As Sampling Networks Age: The Gaps In Groundwater Monitoring, Angela Leone
Undergraduate Distinction Papers
Groundwater management is an important facet of protecting this important resource. One way that we ensure proper groundwater management is through the regular, long-term monitoring of groundwater wells at waste management sites throughout the country. This study investigates potential changes to groundwater quality attributed to degradation of well construction materials rather than impacts to aquifers from wastes. This assessment was completed using a data analysis of groundwater trends at closed landfill sites. An analysis of fifty-five sites was completed and three sites met our criteria for suitable data history. Due to the lack of suitable data, a more thorough investigation …
Private Land, Public Trust: Strategic Conservation Planning For Public Wildlife On Private Lands Through The Usfws Partners For Fish And Wildlife Program, Clint Wirick
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
Law requires federal agencies to develop long-term strategic plans. Strategic plans define goals, objectives, and performance measures defining how the agencies and programs will reach their stated goals. U.S. Fish and Wildlife Service’s Partners for Fish and Wildlife (PFW) develops strategic plans every five years. Each individual state develops a plan for their respective state. Those state plans are compiled for the region and become part of Regional Comprehensive Strategic Plan. The current strategic plan expires in 2021. States will begin the strategic planning process in 2020. In Utah, PFW staff will also begin developing a strategic plan for the …
Analyzing The Effects Of Of Seasonal Land Cover And Precipitation On The Sediment Delivery Ratio Of An Agriculture Dominated Watershed., Jonah Liebman
Analyzing The Effects Of Of Seasonal Land Cover And Precipitation On The Sediment Delivery Ratio Of An Agriculture Dominated Watershed., Jonah Liebman
Electronic Theses and Dissertations
Soil erosion is of escalating importance as increasing population and climate change have put increasing pressures on agricultural food production. Vegetation and precipitation are two factors that control the amount of soil erosion extant within a region. Sediment delivery ratios (SDRs) assess the ratio of soil eroded from a watershed system that is permanently removed from the system through stream sediment discharge. Using 1) river discharge and sediment concentration data and 2) the Revised Universal Soil Loss Equation (RUSLE), this thesis analyzes fluctuations in monthly SDRs for an average hydroclimatological crop-harvest season for the Senachwine Creek watershed, IL. Through calculating …

Tree Removal Analysis Of The 2018-2019 Gambles Mill Eco-Corridor Restoration, Zach Harrell
Environmental Studies Senior Seminar Projects
Trees have been extensively researched, and it has been concluded that they are useful not only useful tools in enhancing biofiltration, as well as managing stormwater and retaining sediment, but they also benefit the health of the ecosystem as a whole. But as the University of Richmond’s Gambles Mill Eco-corridor was restored between 2018 and 2019 in order limit to the amount of phosphorus, nitrogen, and other sediment flowing into the Little Westham Creek; many of the trees that combat these problems were removed. The following research intends to analyze the number of trees actually removed throughout the restoration, as …
Stream Restoration As A Method Of Improving Local Water Quality, Emily George
Stream Restoration As A Method Of Improving Local Water Quality, Emily George
Environmental Studies Senior Seminar Projects
Projects of stream restoration are a known Best Management Practice (BMP) to approach stormwater management, and have been adopted globally as a means of improving local hydrology. Urbanization has led to an increase in impervious surfaces, resulting in deteriorated streams, many of which are subject to stream restoration. Stormwater control measures (SCM), such as stream restoration, are considered to be a subset of green infrastructure as a method to reconnect streams with surrounding riparian areas, revitalize original hydrology, and support the local ecosystems. This paper looks into the viability of stream restoration as a way of improving water quality, focusing …
