Nutrient And Fecal Microbe Assessment Of The Water Quality Of Tates Creek, Madison County, Kentucky, Krisopher H. Carroll, Walter S. Borowski
EKU Faculty and Staff Scholarship
Tates Creek is a significant tributary to the Kentucky River that has shown high levels of microbial and nutrient pollution. We sampled the waters of Tates Creek comprehensively by occupying 25 stations along its 13-mile length, collecting stream water at the confluence of major tributaries from its headwaters to the Kentucky River. Samples were collected four times between May and August 2011 during dry periods as well as immediately after rainfall events.
We measured ammonium (NH4+), nitrate (NO3-) and phosphate (PO4-) concentrations using colorimetry. Microbial samples were measured for total coliform …
Concentration Of Heavy Metals In The Waters And Surface Sediments Of Wilgreen Lake, Madison County, Kentucky: An Evaluation Of Plausible Sources, Chad Von Gruenigen, Walter S. Borowski
Concentration Of Heavy Metals In The Waters And Surface Sediments Of Wilgreen Lake, Madison County, Kentucky: An Evaluation Of Plausible Sources, Chad Von Gruenigen, Walter S. Borowski
EKU Faculty and Staff Scholarship
Heavy metal pollution remains a problem in natural waters, particularly for localities near plausible anthropogenic sources. We assayed the level of heavy metals in surface waters and within surface sediments of Wilgreen Lake, whose watershed drains industrial, urban, agricultural, and residential areas near Richmond, Kentucky. We sampled both surface (oxic) and deep waters (anoxic) when the lake was stratified over Summer 2010. Water samples were treated according to U.S. Environmental Protection Agency (EPA) protocols and were digested with trace-metal-grade nitric and hydrochloric acids. Sediment samples were collected with a grab sampler and digested using established EPA procedures with trace-metal-grade nitric …
Patterns Of Heavy Metal Concentration In Core Sediments, Wilgreen Lake, Madison County, Clint Mcmaine, Walter S. Borowski
Patterns Of Heavy Metal Concentration In Core Sediments, Wilgreen Lake, Madison County, Clint Mcmaine, Walter S. Borowski
EKU Faculty and Staff Scholarship
Accumulation of heavy metals in ecosystems is a known environmental problem, and several possible industry sources occur within the watershed of Wilgreen Lake, which is fed its two major tributaries, Taylor Fork and Old Town Branch. Elevated levels of cadmium, copper, lead, and nickel were found within the waters of Wilgreen Lake during a preliminary survey in 2007. A possible source of these contaminant occurrences is diffusion from lake sediments, which record past and present activities within their drainage basins.
To obtain a history of anthropogenic practices within the drainage basin, we took 1-meter-long cores of lake sediment in each …
Marine Vertebrate Remains From Middle-Late Devonian Bone Beds At Little Hardwick Creek In Vaughns Mill, Kentucky And At The East Liberty Quarry In Logan County, Ohio, John M. James
Browse all Theses and Dissertations
Stratigraphic, lithologic, faunal and condont biozone analysis will provide insight to whether or not East Liberty Bone Bed, in Logan County, Ohio, and Little Hardwick Creek Bone Bed C, in Vaughns Mill, Kentucky, are chronostratigraphic correlations to one another; they are separated by 370 kilometers (230 miles). Material from each bed was collected and broken down in acid and analyzed. Remaining residue after acid treatment was analyzed under a dissecting microscope for lithological and fossil contents, identified from previous fossil vertebrate findings at other locations.
Final analysis of these beds showed that lithologically and faunally they are very similar. However, …

Patterns Of Heavy Metal Concentration In Core Sediments, Wilgreen Lake, Madison County, Kentucky, Clint Mcmaine, Walter S. Borowski
EKU Faculty and Staff Scholarship
Elevated levels of cadmium, copper, lead, and nickel were found within the waters of Wilgreen Lake during a preliminary survey in 2007. Accumulation of heavy metals in freshwater systems is a known problem. Heavy metals enter the lake in the dissolved phase or adsorbed onto sediment particles and may be linked to industries within the lake’s watershed. Under certain geochemical conditions such as anoxia, heavy metals may detach from sediment particles and diffuse into overlying lake waters, causing a renewed influx of heavy metals into the ecosystem. We hypothesize that heavy metals should decrease in concentration upcore as a result …

An assessment of how present agricultural practices have influenced shallow groundwater and soil quality was conducted on a 540-acre farm in north-central Henderson County. Groundwater- and soil-quality data were collected from row crop (corn and soybean), alfalfa, and pasture fields. In addition to the field settings, groundwater and soil data were collected from the existing farmyard and an abandoned feedlot. Groundwater samples were analyzed for pH, specific conductance, temperature, oxidation-reduction potential, metals, anions, nutrients, herbicides, and various isotopes. Soil samples were analyzed for pH, bioavailable phosphorus, potassium, calcium, magnesium, zinc, organic matter, total nitrogen, and inorganic nitrogen (nitrate-N). Soil- and …
Ground Motion For The Maximum Credible Earthquake In Kentucky, Zhenming Wang
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 …

Soil- And Groundwater-Quality Data For An Abandoned Cattle And Hog Feedlot In Henderson County, Kentucky, E. Glynn Beck, James S. Dinger, Eugenia Pena-Yewtukhiw, John H. Grove
Information Circular--KGS
Groundwater samples collected from a livestock well in southwestern Henderson County, Ky., contained nitrate-N concentrations greater than 20 mg/L, two times the U.S. Environmental Protection Agency’s maximum contaminant level. The well is located in an abandoned cattle and hog feedlot. The feedlot is located in an upland bedrock setting with Pleistocene loess overlying Pennsylvanian bedrock. One hundred twenty-one soil cores were collected to better define the areal extent of organic-rich soil believed to be the source of the elevated nitrate-N in the groundwater. Cores were collected on 25-ft centers to a depth of 4 ft below the land surface. Soil …
Evaluation Of Geologic Co2 Sequestration Potential And Co2 Enhanced Oil Recovery In Kentucky, Thomas M. Parris, Stephen F. Greb, Brandon C. Nuttall
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 …
Sources And Occurrences Of Nonpoint-Source Chemicals In Groundwater, Jackson Purchase Region, Kentucky, R. Stephen Fisher, E. Glynn Beck
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 …

Use Of Surface Geophysical Techniques To Locate A Karst Conduit In The Cane Run - Royal Spring Basin, Kentucky, Ganesh N. Tripathi
Use Of Surface Geophysical Techniques To Locate A Karst Conduit In The Cane Run - Royal Spring Basin, Kentucky, Ganesh N. Tripathi
University of Kentucky Master's Theses
Groundwater flow in karst terrains is difficult to map because it can be concentrated through conduits that do not necessarily coincide with the surface features. We applied electrical resistivity (ER) and self-potential (SP) techniques at three sites to locate an inferred trunk conduit feeding a major spring in the Inner Bluegrass region of Kentucky. Royal Spring is the primary water supply for the city of Georgetown; the upper part of its basin coincides with the Cane Run watershed. ER and SP profiles were perpendicular to the inferred trunk conduit orientation. ER profiles (972 m total length) were measured using a …

Seasonal Changes In Stratification And Oxygen Content Of A Eutrophic Lake, Wilgreen Lake, Madison County, Kentucky, Jill Hunter, Walter S. Borowski
EKU Faculty and Staff Scholarship
Wilgreen Lake (Madison County, Kentucky) is listed by the Environmental Protection Agency as nutrient-impaired. The overabundance of nutrients is likely linked to the land-use practices in this area. Cattle pasture, residential developments served by septic systems, and urban/industrial areas lie in the lake’s watershed. We have studied the lake for two years to characterize its physical and chemical characteristics, and to identify nutrient sources.
The 2007 field season began in March and continued through October. We measured temperature and oxygen levels along with other parameters at 1-meter depth intervals at 19 stations distributed along the length of the lake and …

Using E. Coli And Bacteroides Distribution And Abundance In A Eutrophic Lake As A Tracer For Nutrient Inputs, Wilgreen Lake, Madison County, Kentucky, Theresa A. Aguiar, Walter S. Borowski, Alice C. Layton, Larry Mckay
EKU Faculty and Staff Scholarship
Wilgreen Lake is a eutrophic lake that has been listed on the EPA’s 303d list as nutrient impaired. Potential sources of this impairment are likely from humans, cattle manure, and fertilizers. We suspect that the majority of nutrients originate from human sources, namely from septic tank effluent emanating from key housing developments ringing the lakeshore. We test our hypothesis with conventional microbial assays (Escherichia coli) and RT-PCR techniques (Bacteroides).
We took water samples at 19 sampling locations on 4 occasions, and measured the abundance of Escherichia coli using IDEXX methods. Corresponding sub-samples slated for potential PCR …
Foundation Problems And Pyrite Oxidation In The Chattanooga Shale, Estill County, Kentucky, Warren H. Anderson
Foundation Problems And Pyrite Oxidation In The Chattanooga Shale, Estill County, Kentucky, Warren H. Anderson
Report of Investigations--KGS
Pyrite oxidation in the Chattanooga Shale has caused serious foundation problems in numerous buildings and structures in Estill County, Ky. Pyrite oxidizes and various secondary sulfates form when excavated shale or shale fill are used in foundations. These secondary sulfates are water- and humidity-sensitive and can form when only minor amounts of water are present in foundation materials. These sulfates form by crystal growth and expand by volume change, which causes subsequent soil expansion and heaving of any foundation materials when the materials are confined. Several structures have undergone expensive remediation to repair damaged sidewalks, floors, walls, and foundations. Zones …

Effect Of Avail® Polymer Applied To Phosphorus Fertilizers On Dry Matter Production And P Uptake Of Fescue At Princeton, Ky, Lloyd W. Murdock, John James Olson, Gene Olson
Soil Science News and Views
A study was conducted near Princeton, KY to determine if a polymer (AVAIL®) applied to diammonium phosphate (DAP, 18- 46-0) and mono ammonium phosphate (MAP, 11-52-0) would increase (P) phosphorus use efficiency in fescue production on a low P testing soil, when compared to an untreated phosphate fertilizer. AVAIL® (Specialty Fertilizer Products, Belton, MO) is presently being sold in Kentucky as a product to improve phosphorus fertilizer efficiency.
Groundwater Quality In Kentucky: Atrazine, Bart Davidson, R. Stephen Fisher
Groundwater Quality In Kentucky: Atrazine, Bart Davidson, R. Stephen Fisher
Information Circular--KGS
Atrazine is an organic herbicide used for selective control of broadleaf and grassy weeds in crops such as corn, soybeans, sorghum, sugarcane, macadamia nuts, pineapples, pine trees, grasslands, and roses. Atrazine does not harm the crops, which can absorb and metabolize the herbicide, thereby removing the toxins. It controls targeted plants by inhibiting photosynthesis (Wilkes University Center for Environmental Quality, 2003). Atrazine is a white, odorless, crystalline powder that dissolves readily in water and does not occur naturally. It is widely used because of its low cost and ability to reduce crop losses from weed interference.
Groundwater Quality In Kentucky: Iron, R. Stephen Fisher, Bart Davidson
Groundwater Quality In Kentucky: Iron, R. Stephen Fisher, Bart Davidson
Information Circular--KGS
Iron is one of the most abundant elements in rocks and soils, and one of the most common problems in groundwater supplies. Rainwater seeping through soils and bedrock dissolves iron and carries it to wells and springs. In deep groundwater systems that lack oxygen, iron occurs as dissolved ferrous ion and the water is clear. Under oxidizing conditions such as in shallow groundwater systems or where the water is exposed to air at a tap or faucet, however, iron converts to a ferric form when it combines with oxygen to form reddish-brown rust particles. In addition to natural sources, elevated …

Groundwater Quality In Kentucky: 2,4-D, Bart Davidson, R. Stephen Fisher
Information Circular--KGS
2,4-dichlorophenoxyacetic acid, commonly known as 2,4-D, is an herbicide used for selective control of broadleaf and grassy weeds in crops such as corn and wheat, along roadways and rights-of-way, and on pasture and rangeland. 2,4-D is the most widely used herbicide in the world, and the third most widely used in North America after metolachlor and atrazine. 2,4-D is a synthetic, organic, white to yellow, odorless, crystalline powder that dissolves readily in water. It is widely used today primarily because of its low cost.
Groundwater Quality In Kentucky: Manganese, R. Stephen Fisher, Bart Davidson
Groundwater Quality In Kentucky: Manganese, R. Stephen Fisher, Bart Davidson
Information Circular--KGS
Manganese is a common constituent of Kentucky rocks and soils and, along with iron is one of the most widespread causes of problems in groundwater supplies. Rainwater seeping through soils and bedrock dissolves manganese and carries it in the groundwater system to wells and springs. In deep, slow-moving systems that lack oxygen, manganese remains in solution. Under oxidizing conditions, however, such as in shallow groundwater systems or where the water is exposed to air, manganese combines with oxygen to form black particles that can clog plumbing fixtures and stain containers and clothing.
