A Survey Of Source And Finished Water Supplies For Giardia Cysts And Cryptosporidium Oocysts, Lisa Martin Sexton

KWRRI Research Reports

The occurrence of Giardia lamblia cysts and Cryptosporidium parvum oocysts was determined from source and treated drinking water supplies at selected water treatment facilities in Eastern Kentucky. Giardia and Cryptosporidium are two human protozoan parasites often found in water supplies due to fecal contamination. Characteristic cysts and oocysts were identified from large volume water samples, typically 100 gallons for raw samples and 1,000 gallons for finished water, using an indirect fluorescent antibody specific for Giardia and Cryptosporidium. Source water from four different water treatment facilities utilizing a reservoir, river, and two creeks were assayed. All sites exhibited Giardia lamblia …

Sorption Of Chlorinated Organic Compounds By Sedimentary Rocks, Paul M. Mcginley, S. Kesaraju, Ronald D. Gruzesky

KWRRI Research Reports

The sorption of dichlorobenzene and trichlorobenzene on carbonate and shale rocks collected in Kentucky demonstrate that rock organic matter content is a good indicator of sorptive reactivity in rock systems. Although this is similar to soil systems, significant differences between sorption in rock and soil systems exist. Sorption isotherms on these rocks are nonlinear and sorption can be an order of magnitude higher than predicted using correlations from soils and their organic matter content. This sorption reaction could lead to significant concentration tailing during contaminant cleanup. Experimental elution of trichloroethylene from rock filled columns verified that cleanup times might be …

The Biological Speciation And Toxicokinetics Of Aluminum, Emily Devoto, Robert A. Yokel

Pharmaceutical Sciences Faculty Publications

This review discusses recent literature on the chemical and physiological factors that influence the absorption, distribution, and excretion of aluminum in mammals, with particular regard to gastrointestinal absorption and speciation in plasma. Humans encounter aluminum, a ubiquitous yet highly insoluble element in most forms, in foods, drinking water, and pharmaceuticals. Exposure also occurs by inhalation of dust and aerosols, particularly in occupational settings. Absorption from the gut depends largely on pH and the presence of complexing ligands, particularly carboxylic acids, with which the metal can form absorbable neutral aluminum species. Uremic animals and humans experience higher than normal body burdens …

Use Of Riparian Vegetated Filter Strips To Reduce Nitrate And Fecal Contamination In Surface Water, Mark S. Coyne, Robert L. Blevins, Rebecca A. Gilfillen

KWRRI Research Reports

This research assessed fecal bacteria trapping in surface runoff by grass filters and their potential to enhance NO₃^- removal via denitrification. Grass filter strips 9.0 m long trapped over 99% of the soil in surface runoff in 1992. Fecal coliform removal was less than 75%. In 1993, 9.0 and 4.5 m grass filter strips trapped 99 and 95% of the sediment, respectively. Fecal coliform trapping efficiency was 90% in 9.0 m grass filters and 75% in 4.5 m filters. Fecal streptococci trapping efficiency was 77% in 9.0 m grass filters and only 56% in 4.5 m filters. Fecal …

Tractor Overturn Kills Farmer, Kentucky Injury Prevention And Research Center

Fatality Case Reports--Tractors/Logging

A 60-year-old farmer died when the tractor he was operating rolled over on top of him. The victim was attempting to hook up a camper to a tractor in order to pull it to a paved roadway. Having recently sold the camper, the farmer, assisted by the buyer, was preparing to remove it from the farmer's property.

The victim, driving a tractor which was equipped with a front end loader, pulled forward past the tongue of the camper in order to line up the tractor draw bar with the camper tongue. The ground sloped more than one-half inch per foot …

Nitrous Oxide Flux From Poultry-Manured Erosion Plots And Grass Filters After Simulated Rain, Mark S. Coyne, R. A. Gilfillen, Robert L. Blevins

Plant and Soil Sciences Faculty Publications

Adding carbon-rich materials to fields, like manure, may enhance denitrification. Grass filters, which are used to trap surface runoff from these fields, may also provide a carbon-rich environment that favors water infiltration and denitrification. Nitrous oxide (N₂O) may be evolved these settings. It is a radiatively important trace gas and intermediate in the denitrification pathway and several other microbial processes. We measured N₂O flux, after simulated rain, using a soil cover technique in poultry-manured plots and grass filters receiving their runoff. Intact soil cores were used to relate the N₂O flux to the denitrification …

Pathway Analysis Of Contaminant Fate And Transport For Generic Soil Standards And Application To Kentucky Underground Storage Tanks, Paul M. Mcginley

KWRRI Research Reports

A generic contaminant migration pathway was used to develop concentration adjustment factors relating soil contamination levels to concentrations in migrating media. These concentration adjustments are based on relatively simple models and parameter values from the literature. The methodology is a screening level tool and is not designed to be used in the site specific analysis where additional information on the source of contamination and the local conditions is available.

The results demonstrate that contaminant concentrations can be very sensitive to the processes which occur during the migration of contaminants.Because the rates of these processes may be site specific it is …

Impact Of Riparian Grass Filter Strips On Surface-Water Quality, Alex W. Fogle, Daniel I. Carey, Billy J. Barfield, Robert L. Blevins, Vasilios P. Evangelou, Cora E. Madison, Shreeram P. Inamdar

Information Circular--KGS

The effectiveness of natural riparian grass filter strips in removing sediment and agricultural chemicals from surface runoff was studied using no-tillage and conventional-tillage erosion plots. Runoff from the tillage plots was directed onto 4.57, 9.14, and 13.72 m (15, 30, and 45 ft.) length filter strips, where the inflow and outflow concentrations and sediment size distributions were measured. Trapping efficiencies for sediment and agricultural chemicals typically ranged near or above 90 percent, mainly because of high infiltration rates. The filters also significantly reduced peak discharge concentrations, which reduced the impact of sediment and agricultural chemicals on receiving surface waters.

Modification Of Highway Soil Subgrades, Tommy C. Hopkins, Tony L. Beckham, David Q. Hunsucker

Kentucky Transportation Center Research Report

Major study objectives were to develop highway pavement subgrade stabilization guidelines, examine long-term benefits of chemical stabilizers, such as cement, hydrated lime, and two byproducts from industrial processes, and to establish a subgrade stabilization program in Kentucky. In developing a program, a number of design and construction issues had to be resolved. Factors affecting subgrade behavior are examined. Changes in moisture content and CBR strengths of untreated and chemically treated subgrades at three experimental highway routes were monitored over a 7- year period. CBR strengths of the untreated subgrades decreased dramatically while moisture contents increased. CBR strengths of subgrade sections …

Frequency Of Mug Negative Escherichia Coli In Kentucky Groundwater Samples, Mark S. Coyne, J. C. Shuler

Plant and Soil Sciences Faculty Publications

MUG negative Escherichia coli are a small fraction (2.5%) of the total E. coli in Kentucky groundwater samples. It is unlikely that they alone will cause a significant potential to underestimate fecal contamination using MUG as the primary criterion for that assessment. An unresolved question is how effectively MUG-based, defined-substrate tests address false negative water samples containing MUG positive E. coli.

Chloroform Contamination In The Louisville Aquifer: An Investigation Of Its Occurrence And Propagation, Sergio E. Serrano

KWRRI Research Reports

This report presents the main results of an investigation on the nature and propagation of an accidental spill of chloroform in the Louisville aquifer, Kentucky. Much of the effort is concentrated on the development of mathematical models to either reconstruct the history of evolution of the plume, or forecast its propagation in the future. Chloroform is a dense halogenated solvent which exhibits a special migration pattern in porous media: Because of this and the relative absence of a conceptual theory on its hydrodynamics in porous media, meaningful predictive models will have to deal with many unresolved theoretical aspects of contaminant …
