Self-Reported Consumption Of Bottled Water V. Tap Water In Appalachian And Non-Appalachian Kentucky, Jason W. Marion

Journal of Appalachian Health

Introduction: Quantitative studies on drinking water perceptions in Appalachia are limited. High-profile water infrastructure failures in the U.S. and Eastern Kentucky, coupled with human-made and natural disasters in the Appalachian Region, have likely impacted opinions regarding tap water.

Purpose: To use existing unexplored data to describe baseline tap water v. bottled water consumption in Kentucky.

Methods: Telephone-based cross-sectional data were obtained from the 2013 Kentucky Health Issues Poll (KHIP) directed by the Foundation for a Healthy Kentucky. Among many items in KHIP, self-reported consumption of bottled water over tap water, reasons for bottled water use, and demographic data were obtained. …

Development Of Mine Soils In A Chronosequence Of Forestry-Reclaimed Sites In Eastern Kentucky, Kenton L. Sena, Kevin M. Yeager, Christopher D. Barton, John M. Lhotka, William E. Bond, Kimberly J. Schindler

Lewis Honors College Faculty Publications

Surface mining for coal has contributed to widespread deforestation and soil loss in coal mining regions around the world, and particularly in Appalachia, USA. Mined land reforestation is of interest in this and other regions where forests are the dominant pre-mining land use. This study evaluated mine soil development on surface-mined sites reforested according to the Forestry Reclamation Approach, representing a chronosequence of time ranging from 0 to 19 years after reclamation. Soils were sampled in depth increments to 50 cm and analyzed for a suite of soil physical and chemical characteristics. Overall, soil fines (silt + clay) tended to …

Bundles And Hotspots Of Multiple Ecosystem Services For Optimized Land Management In Kentucky, United States, Yang Bai, Thomas O. Ochuodho, Jian Yang, Domena A. Agyeman

Forestry and Natural Resources Faculty Publications

Ecosystem services are benefits that the natural environment provides to support human well-being. A thorough understanding and assessment of these services are critical to maintain ecosystem services flow through sustainable land management to optimize bundles of ecosystem services provision. Maximizing one particular ecosystem service may lead to reduction in another. Therefore, identifying ecosystem services tradeoffs and synergies is key in addressing this challenge. However, the identification of multiple ecosystem services tradeoffs and synergies is still limited. A previous study failed to effectively capture the spatial interaction among ecosystem services as it was limited by “space-to-time” substitution method used because of …

Occupancy And Abundance Of Stream Salamanders Along A Specific Conductance Gradient, Jacob M. Hutton, Steven J. Price, Simon J. Bonner, Stephen C. Richter, Christopher D. Barton

Forestry and Natural Resources Faculty Publications

In the Central Appalachians (USA), mountaintop-removal mining accompanied by valley fills often leads to streams with elevated specific conductivity (SC). Thus, the ionic composition of freshwaters in this region is hypothesized to be a driver of the distribution and abundance of freshwater taxa, including stream salamanders. We examined the association between SC and stream salamander populations by conducting salamander counts in 30 southeastern Kentucky streams across a continuous gradient of SC that ranged from 30 to 1966 μS/cm. We counted 2319 salamanders across 5 species and, using a hierarchical Bayesian version of the N-mixture model, found a negative association between …

Predicting And Mapping Plethodontid Salamander Abundance Using Lidar-Derived Terrain And Vegetation Characteristics, Marco Antonio Contreras, Wesley A. Staats, Steve J. Price

Forestry and Natural Resources Faculty Publications

Aim of the study: Use LiDAR-derived vegetation and terrain characteristics to develop abundance and occupancy predictions for two terrestrial salamander species, Plethodon glutinosus and P. kentucki, and map abundance to identify vegetation and terrain characteristics affecting their distribution.

Area of study: The 1,550-ha Clemons Fork watershed, part of the University of Kentucky’s Robinson Forest in southeastern Kentucky, USA.

Materials and methods: We quantified the abundance of salamanders using 45 field transects, which were visited three times, placed across varying soil moisture and canopy cover conditions. We created several LiDAR-derived vegetation and terrain layers and used these …

Influence Of Timber Harvesting Operations And Streamside Management Zone Effectiveness On Sediment Delivery To Headwater Streams In Appalachia, Daniel Bowker, Jeffrey W. Stringer, Christopher D. Barton

Forestry and Natural Resources Faculty Publications

Disturbances created by timber harvesting equipment and associated haul roads and skid trails can create overland sediment flows (sediment paths), especially in steeply sloping terrain, leading to stream sedimentation. This study investigated the effect of variables associated with GPS tracked harvest equipment movement, skid trail development and retirement, topography, and streamside management zone (SMZ) width and tree retention on sediment delivery to streams. While the intensity of harvest equipment traffic was not correlated with sediment path development, the presence and location of skid trails were. All of the sediment paths were found to originate at water control structures, influenced by …

Using Watershed Pour-Point Elevations To Evaluate The Base Of Fresh Groundwater In The Cumberland Plateau Of Eastern Kentucky, Ethan S. L. Davis, Thomas M. Parris, Jerrad Grider

Report of Investigations--KGS

Horizontal drilling with hydraulic fracturing at shallow depths (less than 2,200 ft) in the Devonian Berea Sandstone oil and gas play, along with the potential for high-volume hydraulic fracturing in the nascent Cambrian Rogersville Shale gas play, have generated a renewed interest in protecting groundwater quality in eastern Kentucky. A critical component of protection is an accurate understanding of the distribution of fresh water in the subsurface. The “Fresh-Saline Water Interface Map of Kentucky” by H.T. Hopkins, published by the U.S. Geological Survey and Kentucky Geological Survey in 1966, has been a critical reference for assessing the maximum depth of …

Field Investigation Of An Active Landslide In Kentucky: A Framework To Correlate Electrical Data And Shear Strength, Matthew M. Crawford, L. Sebastian Bryson

Report of Investigations--KGS

Landslide hazard assessments are best accomplished by a multidisciplinary approach that connects geologic processes with geotechnical behavior. Tools to accomplish this in the field include geologic characterization, hydrologic monitoring, and geophysical surveys, and in the laboratory, soil-strength testing. Volumetric water content, soil-water potential (suction), local rainfall, and in situ electrical conductivity were measured at a shallow colluvial landslide in Kentucky. Surface electrical-resistivity surveys were also conducted to support interpretations of depth to failure, lithologic differences, and changes in moisture content over time. Correlations of hydrologic data with electrical measurements and shear strength indicate that observed changes in the degree of …

Survival And Cause-Specific Mortality Of White-Tailed Deer (Odocoileus Virginianus) Neonates In A Southeastern Kentucky Population, Joseph R. Mcdermott

Theses and Dissertations--Forestry and Natural Resources

Maintaining desired numbers of wildlife species requires an understanding of species-specific population dynamics. For ungulate species such as the white-tailed deer (Odocoileus virginianus), understanding the neonatal survival rate of a population and factors that influence that survival rate, may be two of the most important factors to successful deer management. We examined neonatal survival in an eastern Kentucky population of deer living in relatively low densities (/ km²), with adequate habitat and supposedly poor population growth. Neonates (102) were captured in the summer birth periods of 2014 - 2016 and radio-monitored until the beginning of the …

Establishment Of Serological Reference Ranges For Elk In Kentucky And Effects Of Quarantine And Translocation On Elk, Aaron M. Hildreth

Theses and Dissertations--Forestry and Natural Resources

Establishing blood serum profiles is important for understanding animal disease ecology and nutrition, the effects of capture and immobilization, and general physiological variation among individuals and populations. Elk (Cervus elaphus nelsoni) have been successfully translocated to several states for reintroduction or population augmentation, including most recently in Kentucky, where over the course of three years (2011-13) wild elk were captured, temporarily quarantined, and subsequently moved to Missouri and Virginia to establish populations in those states. I used this opportunity to collect a variety of biological samples, including blood from which I present and compare serological profiles for a …

Comparison Of Protein Phosphatase Inhibition Assay With Lc-Ms/Ms For Diagnosis Of Microcystin Toxicosis In Veterinary Cases, Caroline E. Moore, Jeanette Juan, Yanping Lin, Cynthia L. Gaskill, Birgit Puschner

Veterinary Diagnostic Laboratory Faculty Publications

Microcystins are acute hepatotoxins of increasing global concern in drinking and recreational waters and are a major health risk to humans and animals. Produced by cyanobacteria, microcystins inhibit serine/threonine protein phosphatase 1 (PP1). A cost-effective PP1 assay using p-nitrophenyl phosphate was developed to quickly assess water and rumen content samples. Significant inhibition was determined via a linear model, which compared increasing volumes of sample to the log-transformed ratio of the exposed rate over the control rate of PP1 activity. To test the usefulness of this model in diagnostic case investigations, samples from two veterinary cases were tested. In August …

Effects Of Mountaintop Removal Mining On Population Dynamics Of Stream Salamanders, Sara B. Freytag

Theses and Dissertations--Forestry and Natural Resources

Mountaintop removal mining (MTR) is a notorious stressor of stream ecosystems in the Central Appalachians. Valley fills (VF) lead to reduced occupancy, abundance, and species richness of stream salamanders. Multiple factors may be responsible for these reductions, but specifically habitat fragmentation and degradation may reduce colonization rates and increase local extinction rates. From 2013-2015, repeated counts of salamanders were conducted in stream reaches impacted by MTR/VF and compared to counts in reference reaches to answer the question: do stream salamander population dynamics differ between stream reaches impacted by MTR/VF and reference stream reaches? I also investigated dynamics of stream habitat …

Heavy-Oil And Bitumen Resources Of The Big Clifty Sandstone, Northeastern Grayson County And Adjacent Hardin County, Kentucky, J. Richard Bowersox

Report of Investigations--KGS

Rock asphalt (bitumen-saturated sandstone) was produced from the Big Clifty Sandstone near Tar Hill and Big Clifty in northeastern Grayson County, and at Summit in adjacent Hardin County, from 1889 to 1940. Noncommercial amounts of oil were distilled from Big Clifty rock asphalt before 1930. Resource assessments conducted throughout the area during the mid-1920's described substantial rock-asphalt deposits. Later assessments in 1951, 1965, and the early 1980's, however, overlooked the northeastern Grayson County area. A new evaluation in 2015 estimated that the historically developed area between Clifty Creek and meeting Creek, and between the Summit Fault and Eveleigh Fault Zone, …

The Geologic Context Of Landslide And Rockfall Maintenance Costs In Kentucky, Bethany L. Overfield, Daniel I. Carey, Gerald A. Weisenfluh, Rebecca Wang, Matthew M. Crawford

Report of Investigations--KGS

Kentucky Transportation Cabinet maintenance cost data for landslides and rockfalls were associated with geology along Kentucky roadways in a three-phase study. Work-order costs collected over 7 yr were divided into 1-mi segments, and the segment midpoints were assigned to geologic formation. Formations that were expensive to maintain were not necessarily those that were the most frequently repaired and vice versa. Costs and frequency of repair were greater in eastern and northern Kentucky, where slope and relief are greater than in other parts of the state and shale-bearing geologic units prevail.

Geologic, Geotechnical, And Geophysical Investigation Of A Shallow Landslide, Eastern Kentucky, Matthew M. Crawford, Junfeng Zhu, Steven E. Webb

Report of Investigations--KGS

In eastern Kentucky, landslides occur in colluvial soils or at the colluvium-bedrock contact, and are commonly triggered by heavy rainfall. These slides occur particularly where steep slopes and weak rocks combine with various methods of slope modification. Landslides can damage roadways, infrastructure, and residences, and mitigation costs can exceed $10 million per year.

The Meadowview landslide in Boyd County was investigated to assess the geologic conditions, extent, and behavior of a rainfall-triggered landslide in eastern Kentucky and evaluate the use of electrical resistivity as a tool to characterize a shallow colluvial landslide. Although this type of landslide is common in …

The MW 4.2 Perry County, Kentucky, Earthquake Of 10 November 2012: Evidence Of The Eastern Tennessee Seismic Zone In Southeastern Kentucky, N. Seth Carpenter, Edward W. Woolery, Zhenming Wang

Earth and Environmental Sciences Faculty Publications

The 10 November 2012 M_w 4.2 Perry County earthquake may represent a continuation of the seismically active Eastern Tennessee seismic zone (ETSZ) farther north than previously recognized into southeastern Kentucky. The mainshock and aftershock data from regional seismic networks and EarthScope’s Transportable Array stations allowed high‐quality determinations of the source parameters. The focal mechanism, depth, and proximity of the mainshock to the New York–Alabama magnetic lineament, a subsurface, crustal‐scale structure that spatially correlates with central ETSZ seismicity, suggest that this earthquake may share the same type of causal geologic structures as the more‐active ETSZ region to the south.

Shallow Groundwater Monitoring Associated With The Deep Saline Reservoir Co2 Storage Test In Hancock County, Kentucky, E. Glynn Beck

Report of Investigations--KGS

A carbon dioxide injection test well was drilled in 2009 to a depth of 8,126 ft below ground surface in Hancock County, Kentucky. Six hundred ninety tons of CO₂ was successfully injected into Knox Group saline aquifers. Two domestic wells (MB and GB) and two domestic springs (CA and RC) were sampled to monitor any potential changes in groundwater quality associated with possible migration of CO₂ from deeper saline aquifers into shallow freshwater aquifers. The four sites were sampled for pH, bicarbonate, total dissolved solids, turbidity, anions, total dissolved metals, dissolved inorganic carbon, total CO₂, and …

Hydrogeologic Investigations Of Pavement Subsidence In The Cumberland Gap Tunnel, James S. Dinger, James C. Currens, Junfeng Zhu, Steven E. Webb, Brad W. Rister, R. C. Graves, David L. Allen, Tim C. Scully

Report of Investigations--KGS

Cumberland Gap Tunnel was constructed under Cumberland Gap National Historical Park in 1996 to improve transportation on a segment of U.S. 25E, connecting Kentucky and Tennessee and restoring Cumberland Gap to its historical appearance.

The concrete pavement in the tunnel started to subside in 2001. Ground penetrating radar surveys revealed voids in many areas of the limestone roadbed aggregate beneath the pavement. To investigate possible hydrogeologic processes that may have caused favorable conditions for voids to form in the aggregate, we studied geology, groundwater flow, and groundwater chemistry in the tunnel using a variety of methods, including bore drilling, packer …

Review Of Kentucky Oil And Gas Production, 2010, Brandon C. Nuttall

Information Circular--KGS

The 2010 oil and natural gas production data by well published by the Kentucky Division of Oil and Gas were analyzed in response to proposed rules for limiting emissions from oil and natural gas facilities. Average daily production was determined for 5,044 oil wells and 12,940 natural gas wells. Of these wells, 955 are combined oil and natural gas producers. The overwhelming majority of Kentucky’s wells are marginal (stripper) wells and produce at rates of less than 10 barrels of oil (or barrels of oil equivalent) per day (bo/d) or 60 thousand cubic feet of natural gas per day (Mcf/d) …

Economic Challenges Facing Kentucky’S Electricity Generation Under Greenhouse Gas Constraints, Energy And Environment Cabinet, Commonwealth Of Kentucky, Department Of Statistics, University Of Kentucky, Center For Applied Energy Research, University Of Kentucky, Pacific Northwest National Laboratory

Statistics Reports

From the preface:

For the Energy and Environment Cabinet (EEC), which has primacy in administering most federal environmental laws and regulations at the state level, we have to understand the implications of what is arguably one of the most challenging issues to confront us—greenhouse gas (GHG) emissions and their impact on climate change. Efforts to reduce GHG or carbon dioxide (CO₂) emissions have moved beyond the point of discussion at the national level, and the United States Supreme Court has ruled that the U.S. Environmental Protection Agency (EPA) has the authority to regulate GHG emissions. Furthermore, while public …

Development And Deployment Of A Bioreactor For The Removal Of Sulfate And Manganese From Circumneutral Coal Mine Drainage, C. B. Mastin, J. D. Edwards, Christopher D. Barton, Anastasios D. Karathanasis, Carmen T. Agouridis, Richard C. Warner

Forestry and Natural Resources Faculty Publications

Surface mining, in the form of contour mining and mountain-top removal, is a common means for retrieving coal in the Appalachian Coal Belt region of Kentucky. Overburden or excess spoil generated by these two methods is placed in valley fills. Traditionally Constructed fills have been shown to adversely impact headwater ecosystems via stream burial and through alterations to the hydrology, sediment supply, water quality and biological composition of downstream reaches. Mine drainages emanating from the toe of valley fills often contain elevated levels of total dissolved solids and heavy metals. Drainage chemistry from Guy Cove, a valley fill located in …

Model Ordinance For Development On Karst In Kentucky: Guidance For Construction On Karst Terrain And The Reduction Of Property Damage And Threat To Human Health Resulting From Karst Geologic Hazard, James C. Currens

Information Circular--KGS

I have dealt with hundreds of incidents of karst-related geohazards; some have caused major damage to buildings and infrastructure. Although cases are largely limited to the ground surface being made unusable, a significant number of structures are damaged by karst flooding or cover collapse each year, which is devastating to families who have lost their homes. Most of these events should never have happened, because the karst hazard could have been avoided by selecting a better building site or designing the building to withstand the damage from the hazard. Furthermore, most of the planning authorities I have had experience with …

Using Lidar To Map Landslides In Kenton And Campbell Counties, Kentucky, Matthew M. Crawford

Report of Investigations--KGS

The geology and topography of northern Kentucky and Cincinnati make the area susceptible to landslides. Decades of development and slope modification have contributed to the area being prone to landslides and having one of the highest costs per capita in the United States for landslide damage. The slow nature of some landslides and incremental damage that can span several decades often result in lack of awareness of the problem, however. Many of the landslides go unreported, and citizens do not take advantage of resources to become educated about mitigating the problem.

Research at the Kentucky Geological Survey developed a methodology …

Characteristics Of Kentucky Agricultural Operations Participating In Nrcs Conservation Programs, Carmen T. Agouridis

MPA/MPP/MPFM Capstone Projects

The Natural Resource Conservation Service (NRCS) designs and promotes a wide variety of conservation practices and programs that enhance the environment by reducing soil erosion, improving water quality, and enhancing and creating wildlife habitat. The impact of these practices and programs is largely dependent on the voluntary participation of landowners. Thus, central to the success of the NRCS conservation programs is an understanding of the characteristics of landowners and operations participating in these programs.

Using operator and operation characteristics from the 1997, 2002, and 2007 Censuses of Agriculture and controlling for county fixed effects, this study 1) identifies significant characteristics …

Sources And Occurrences Of Nonpoint-Source Chemicals In Groundwater, Jackson Purchase Region, Kentucky, R. Stephen Fisher, E. Glynn Beck

Report of Investigations--KGS

Nitrate concentrations that exceed U.S. Environmental Protection Agency drinking-water standards have been reported in Jackson Purchase Region groundwater since the 1960's. More recently, other nonpoint-source chemicals such as pesticides and volatile organic compounds have also been found. The sources of these chemicals and the pathways by which they reach domestic groundwater supplies must be determined to protect human health and to design effective land-management practices.

To investigate the occurrence of nonpoint-source chemicals in Jackson Purchase groundwater, 60 wells were selected on the basis of geographic location, hydrostratigraphic unit penetrated, and well type (bored or drilled); distances to row crops, known …

Ground Motion For The Maximum Credible Earthquake In Kentucky, Zhenming Wang

Report of Investigations--KGS

Although they are not frequent, earthquakes occur in and around Kentucky and pose certain hazards. Assessing seismic hazards is challenging, however, because of a lack of observations. The best estimates of ground motions that could be expected if the maximum credible earthquake occurs in or around Kentucky are depicted in maps showing peak ground acceleration and short-period (0.2 second) and long-period (1.0 second) response accelerations with 5 percent critical damping on hard rock. Another consideration for seismic safety is that the maximum credible earthquake has a long recurrenece interval, from 500 to 1,000 years in the New Madrid Seismic Zone …

Evaluation Of Geologic Co2 Sequestration Potential And Co2 Enhanced Oil Recovery In Kentucky, Thomas M. Parris, Stephen F. Greb, Brandon C. Nuttall

Report of Investigations--KGS

Kentucky gets approximately 95 percent of its electricity from coal-fired power plants, which produce significant amounts of carbon dioxide (CO₂). In 2005, Kentucky coal-fired plants vented 102.8 million short tons of CO₂ into the atmosphere. The economic vitality of the state will be affected by its ability to develop and apply a portfolio of technologies that will mitigate input of CO₂ into the atmosphere. One technology that has the potential to assist in this challenge is geologic carbon storage, which captures CO₂ at point sources and injects it into deep rock strata that can store …
