In my study, I look closely at the EPA’s investigation of the site and the community’s reaction to the findings. In my second piece, I describe my field and lab experience working for the Montana Department of Environmental Quality. During this time, …

Multi-Scaled Approaches For Protecting Montana's Watersheds And Water Resources, Elizabeth Yoder

Graduate Student Portfolios, Professional Papers, and Capstone Projects

The central theme carried among my four portfolio pieces is: using scientific and governmental approaches to conserve watershed health. For the purposes of this portfolio, I define watershed health as a very general term that describes the state of water quantity and quality that is available for human and ecosystem needs in a watershed. I see each of my portfolio pieces focusing on a different scale and method (i.e., science or government, including different levels of government, local, state and federal) for conserving watershed health. My first portfolio piece reviews water quality degradation caused by pharmaceuticals and personal care products …

Assessing The Impact Of A Constructed Wetland Biome On The Ecosystem Health Of Cedar Run, Thomas Vasilopoulos, Casey Lee

Senior Honors Projects, 2010-2019

A wetlands ecosystem is defined as “an area saturated by surface or groundwater at a frequency or duration sufficient to support...a prevalence of vegetation typically adapted for life in saturated soil conditions” (Batzer and Sharitz, 2007). Wetlands serve as biofilters and thus have been used to treat sewage and wastewater, as well as to restore the health of polluted water systems. Solly Walker and Lorinda Palin, owners of a certified natural and biodynamic farm called Avalon Acres located in Broadway, Virginia, constructed a wetland two years ago, using the stream, Cedar Run, that flows through their property. Pollution from agricultural …

Patterns And Sources Of Anthropogenic Contaminants In The Otter Creek Watershed, Madison County, Kentucky, Elijah J. Wolfe

EKU Faculty and Staff Scholarship

Stream systems are often affected by anthropogenic activities that affect water quality and stream ecosystems. Land use typically determines the type and quantity of anthropogenic contaminants entering natural waters. The Otter Creek watershed (170 km²; Madison County, Kentucky) consists predominantly of pasture and rural housing, with some cropland. The basin also receives runoff from the town of Richmond and a sewage treatment plant operates within the watershed. We measured concentrations of nutrients (phosphate, ammonium, nitrate) and fecal microbes to discover levels of anthropogenic contaminants affecting water quality and to identify contaminant sources.

We sampled 4 times in the …

Non-Point Sources And Point Sources For Nutrient And Fecal Microbe Contamination In A Typical Upland Stream: Tates Creek, Madison County, Kentucky, Walter S. Borowski, Malcolm P. Frisbie

EKU Faculty and Staff Scholarship

Tates Creek (Madison County, Kentucky) is characterized by an oversupply of nutrients and fecal microbe contamination. Its watershed is dominated by pastureland and immature woodlands with scattered settlements served by septic systems, whereas, 5% of the watershed drains urban areas of Richmond, Kentucky. Creek waters are eutrophic and commonly display levels of Escherichia coli deemed unfit for human contact by United States Environmental Protection Agency standards. Both point and non-point sources existed for stream contaminants. A secondary sewage treatment plant (STP) discharged effluent into the creek until mid-2011 and was a point source for nitrate and phosphate. Pastureland likely contributes …

Patterns Of Anthropogenic Nutrient Contaminants In The Otter Creek Watershed, Madison County, Kentucky, Elijah D. Wolfe, Walter S. Borowski, Jacob L. Robin

EKU Faculty and Staff Scholarship

We measured nutrient concentrations within the Otter Creek watershed (Madison County, Kentucky) to: (1) discover levels of anthropogenic contaminants affecting the water quality; (2) compare these measurements to a national data set; and (3) identify nutrient sources. The watershed mainly drains rural land characterized by cattle grazing, but also drains the town of Richmond. We sampled throughout the watershed to gain a representative perspective of nutrient levels and specifically targeted localities of suspected anthropogenic nutrient sources. Water samples were passed through a 0.45 mm filter, placed in pre-acidified vials, and measured one to two days after collection. Nutrients – ammonium, …

Water Quality In The Río Pastaza Watershed A Comparative Study Of Ríos Topo, Zuñag, And Pastaza And The Impact Of The Topo Hydroelectric Project Using Macroinvertebrates As Bioindicators, Jesse Vega-Perkins

Independent Study Project (ISP) Collection

Ríos Zuñag, Pastaza, and Topo flow through one of the rainiest and water-rich places in Ecuador. Río Zuñag is a relatively small, pristine montane river and Río Pastaza is a relatively large, contaminated river that receives the untreated wastewater of many communities. Río Topo’s unique watershed and gradient allow it to be home to many plants that have adapted to its unique environment, including the hyperendemic liverwort Myriocolea irrorata. However, in recent years, all of the water of Río Topo has been sold by the state of Ecuador to be developed for hydroelectric projects (HEP). The first of these …

Environmental Social Activism In The San Diego-Tijuana Transborder Region, Christina M. Hirt

Undergraduate Honors Theses

This paper examines the obstacles and opportunities social activists face when attempting to fight environmental injustices in the San Diego-Tijuana transborder region. The study undertakes a case study of the Environmental Health Coalition (EHC) - the leading environmental justice organization in the region, which operates on both sides of the US-Mexico Border. The analyses conclude that despite a strong rhetoric of binationalism employed throughout border activists’ campaigns, the strategies that are utilized on the ground have been vastly local and short-term in focus. While activist organizations like the EHC demonstrate a keen awareness of the binational implications of environmental injustices …

Sources Of Nutrient And Escherichia Coli Contamination Within The Otter Creek Watershed, Madison County, Kentucky, Nathaniel C. Crockett, Walter S. Borowski

EKU Faculty and Staff Scholarship

The Otter Creek watershed exhibits dissolved nutrient (ammonium, NH₄; nitrate, NO₃; phosphate, PO₄) and Escherichia coli contamination that compromises its water quality. The watershed covers a substantial portion of Madison County and consists of Lake Reba, Dreaming Creek, and east and west forks, all of which enter the trunk of Otter Creek before flowing into the Kentucky River. Suspected contaminate sources include leaky sewage system pipes, runoff from pasture land, and septic system leachate. We collected 330 water samples on three occasions during summer 2014 to determine the extent and sources of contamination. Nutrients …

Performance Quantification Of Extensive Green Roof Substrate Blend: Expanded Shale And Biochar, James Sheats

Masters Theses, 2010-2019

Urban stormwater management practices often involve the redirection of runoff to local waterbodies. As such, the quality of runoff directly affects the condition of these receiving waters. Green roofs offer many benefits to the urban environment including attractive aesthetics, thermal insulation for buildings and stormwater runoff reduction. Unfortunately, in order to promote the spread of vegetation, fertilization is often practiced that can lead to elevated nutrient concentrations in runoff and, ultimately, nearby streams, rivers and bays. Different amounts of biochar, pyrolyzed biomass, were added to model green roof trays to test for the ability of this charcoal-like substance to prevent …

River Health In Puyo, Ecuador The Use Of Macroinvertebrates As Bioindicators Of Water Quality And Alternatives To Chlorine For Whitening Clothes In The Puyo River Watershed, Allison Rowe

Independent Study Project (ISP) Collection

Fresh water is an important resource in Puyo, Ecuador, a city named after the Kichwa word for ‘cloudy’ in reference to its overcast weather. However, the Puyo River watershed is the most contaminated in all of Pastaza Province. The objective of this investigation was first to evaluate the health of the Puyo River using macroinvertebrate analyses and measurements of chlorine concentrations, temperature, pH, turbidity, velocity, and flow rate. The second objective was to learn about practices used to whiten clothes in Puyo and perceptions of water quality in order to understand the magnitude of bleach pollution and the population’s awareness …

Construction Of An Environmental Quality Index For Public Health Research, Lynne C. Messer, Jyotsna S. Jagai, Kristen M. Rappazzo, Danelle T. Lobdell

Community Health Faculty Publications and Presentations

Background

A more comprehensive estimate of environmental quality would improve our understanding of the relationship between environmental conditions and human health. An environmental quality index (EQI) for all counties in the U.S. was developed.

Methods

The EQI was developed in four parts: domain identification; data source acquisition; variable construction; and data reduction. Five environmental domains (air, water, land, built and sociodemographic) were recognized. Within each domain, data sources were identified; each was temporally (years 2000–2005) and geographically (county) restricted. Variables were constructed for each domain and assessed for missingness, collinearity, and normality. Domain-specific data reduction was accomplished using principal components …

Agenda: Fracking, Water Quality And Public Health: Examining Current Laws And Regulations, Network For Public Health Law, American Society Of Law, Medicine & Ethics, Public Health Law Research Program

Fracking, Water Quality and Public Health: Examining Current Laws and Regulations (March 20)

Improved technology developments in directional drilling and hydraulic fracturing, more commonly known as "fracking," have resulted in an oil and gas production boom nationwide. Fracking involves pumping pressurized water, sand, and chemicals down wells to crack bedrock, freeing petroleum and natural gas. Wastewater discharges, hydraulic fracturing fluid releases, and other accidental spills pose potential water quality risks, sparking concern for public health.

This webinar will examine the laws and regulations governing water quality issues related to fracking, recent state court decisions affecting regulations, and implications for public health.

The Effect Of Non-Fluoride Factors On Risk Of Dental Fluorosis: Evidence From Rural Populations Of The Main Ethiopian Rift, Julia Kravchenko, Tewodros Rango, Igor Akushevich, Behailu Atlaw, Peter G. Mccornick, R. Brittany Merola, Christopher Paul, Erika Weinthal, Courtney Harrison, Avner Vengosh, Marc Jeuland

Daugherty Water for Food Global Institute: Faculty Publications

Elevated level of fluoride (F⁻) in drinking water is a well-recognized risk factor of dental fluorosis (DF). While considering optimization of region-specific standards for F⁻, it is reasonable, however, to consider how local diet, water sourcing practices, and non-F⁻ elements in water may be related to health outcomes. In this study, we hypothesized that non-F⁻ elements in groundwater and lifestyle and demographic characteristics may be independent predictors or modifiers of the effects of F⁻ on teeth. Dental examinations were conducted among 1094 inhabitants from 399 randomly selected households of 20 rural communities of …
