Biological And Chemical Evaluation Of The Aquatic Environment Of Selected Undeveloped Kentucky Lake Embayments, Marshall Gordon, Morgan E. Sisk

KWRRI Research Reports

This report describes research involving biological and chemical analysis of two undeveloped embayments on Kentucky Lake, namely Anderson and Vickers Bays. Field and laboratory studies were made to assess current biotic standing crops, limnological conditions, levels of inorganic and organic pollutants in the embayments.


Enteric Virus Survival In Package Plants And The Upgrading Of The Small Treatment Plants Using Ozone, Lois S. Cronholm, James R. Mccammon, Marvin Fleischman, Jerry R. Perrich, Valerie Reisser, William Harris, Ronald R. Vanstockum, Khosrow Jaberizadeh, Michael J. Wahl Nov 1976

Enteric Virus Survival In Package Plants And The Upgrading Of The Small Treatment Plants Using Ozone, Lois S. Cronholm, James R. Mccammon, Marvin Fleischman, Jerry R. Perrich, Valerie Reisser, William Harris, Ronald R. Vanstockum, Khosrow Jaberizadeh, Michael J. Wahl

KWRRI Research Reports

Post-chlorinated effluent collected with a portable viral concentrator from four treatment plants in Jefferson County, Kentucky, yielded infective viral particles from three plants from spring through late fall. The pH, ,chlorine, turbidity, and coliform levels of these effluents indicated that viral persistence was correlated with inefficient processing which produced effluent environments that inhibited disinfection by chlorine. The disinfection potential of ozone was tested on secondary effluent and finished water seeded with poliovirus and Esaheriahia coli. Low doses of ozone inactivated viruses and bacteria in treated water, but not in effluent. The inactivation of bacteria by ozone does not appear …


Dams And People: Geographic Impact Area Analysis, Vance E. Arnett, Sue Johnson Sep 1976

Dams And People: Geographic Impact Area Analysis, Vance E. Arnett, Sue Johnson

KWRRI Research Reports

This report attempts to determine the efficacy of using geographic impact areas as analytical sub-groups for the assessment of the impact of multi-purpose reservoir projects on target communities. The impact areas utilized are: the take area; the below-the-dam area; the urban area; and, the adjacent area. Each area is described in detail and each is analyzed for differences in knowledge, previous experience, and perception of impact on community and family.

Data for this study originated from structured and open-ended interviews in Johnson County, Kentucky. Information was collected during two field efforts, the first in February, 1974, the second in August …


Statistical Models For Precipitation, Z. Govindarajulu, Peter Purdue, Frank Cioch Aug 1976

Statistical Models For Precipitation, Z. Govindarajulu, Peter Purdue, Frank Cioch

KWRRI Research Reports

The available data consists of daily rainfall for the past 24 years (1948-1972) for Lexington, Louisville and Paducah. However, for Ashland, the data is available for the period of 40 years (1932-1972). The problem is to find an appropriate family of distributions indexed by a suitable number of parameters that fits the maximum daily rainfall. Further, there might be seasonal variations. The following seasons were considered: (i) Dry Convective season: August 1-0ctober 30; (ii) Early Convective season: May 1-July 31; (iii) Late Convective season: November 1- April 30. After extracting the yearly maximums for each of these seasons (see Appendix …


Legal Institutions For The Allocation Of Water And Their Impact On Coal Conversion Operations In Kentucky, Richard C. Ausness, Gary W. Callahan, Steven W. Dills, Bill H. Flynn, John S. Gillig Aug 1976

Legal Institutions For The Allocation Of Water And Their Impact On Coal Conversion Operations In Kentucky, Richard C. Ausness, Gary W. Callahan, Steven W. Dills, Bill H. Flynn, John S. Gillig

KWRRI Research Reports

The conversion of coal into other types of fuel through gasification and liquefaction has been proposed as a means of coping with America's increasing energy needs. Coal conversion plants require large quantities of water for cooling purposes and for use as a raw material.

There are three types of water allocation presently used in the United States, riparianism, prior appropriation, and administrative permit systems. The common law riparian system is undesirable because under it water rights are insecure and subject to locational use restrictions. Prior appropriation is better, but the permanent water right created under this system results in excessive …


Hydrodynamic Separation Of Solids From Solid-Liquid Mixtures, Harry J. Sterling Jr., Don J. Wood Jun 1976

Hydrodynamic Separation Of Solids From Solid-Liquid Mixtures, Harry J. Sterling Jr., Don J. Wood

KWRRI Research Reports

Several schemes for separating solid pollutants from water flowing in a closed conduit were examined. Separation based on the momentum differential between the solids and liquids and the centrifugal movement of a conveying liquid were both examined under turbulent flow conditions. The study indicated these processes to have limited applications, primarily due to the difficulties in withdrawing a significant fraction of separated flow and the deleterious effects of turbulent mixing. However, utilization of the differential momentum of solid particles and water when flowing laminarly through a pipe was found to be a viable separation scheme. Significant experimental separations (greater than …


Some Of The Effects Of Domestic Sewage Discharged Into Hickman And Jessamine Creeks In Jessamine County, Kentucky, Henry H. Howell, Mike W. Jones, Robert A. Kuehne Feb 1976

Some Of The Effects Of Domestic Sewage Discharged Into Hickman And Jessamine Creeks In Jessamine County, Kentucky, Henry H. Howell, Mike W. Jones, Robert A. Kuehne

KWRRI Research Reports

A 6-week study was made in the summer of 1971 as an initial effort to determine the extent of pollution that the three sewage disposal plants in Jessamine County, Kentucky, are contributing to its streams. With the rapid population increase in Lexington and nearby municipalities, this study should furnish a basis of comparison for future investigations. Eighteen collecting stations were established in riffle areas of Hickman and Jessamine Creeks, and coliform bacteria, macro-invertebrate populations, fish populations and chemical water quality of each riffle area were studied.

Hickman Creek's flow was augmented by approximately 3,100,000 gallons/day (11,735 -m3/day) from …


Supply And Demand In Water Planning: Streamflow Estimation And Conservational Water Pricing, D. I. Carey, C. T. Haan Jan 1976

Supply And Demand In Water Planning: Streamflow Estimation And Conservational Water Pricing, D. I. Carey, C. T. Haan

KWRRI Research Reports

Recent studies indicated the need for development of surface water supplies in Kentucky. Rising resource costs make economically efficient reservoir designs increasingly important. This study was undertaken to provide methods in water supply reservoir design that increase system benefits.

Two major factors influencing reservoir design were studied: estimated future streamflow into the reservoir and demands placed on the reservoir. Standard reservoir sizing methods rely on historical streamflow data. This data is frequently limited and uncertainty in required storage estimates may result. To assess the reliability of a design, the use of mathematical models in simulation studies was proposed. Existing stochastic …


Sensitivity Of Vertebrate Embryos To Heavy Metals As A Criterion Of Water Quality: Phase Iii: Use Of Fish And Amphibian Eggs As Bioindicator Organisms For Evaluating Water Quality, Wesley J. Birge, Albert G. Westerman, Jeffrey A. Black Jan 1976

Sensitivity Of Vertebrate Embryos To Heavy Metals As A Criterion Of Water Quality: Phase Iii: Use Of Fish And Amphibian Eggs As Bioindicator Organisms For Evaluating Water Quality, Wesley J. Birge, Albert G. Westerman, Jeffrey A. Black

KWRRI Research Reports

Fish and amphibian eggs, embryos and early posthatched (larval) stages were evaluated as bioindicator organisms with which to monitor the quality of natural water resources. Eggs of 9 species were cultured in water collected from each of 11 Inner Bluegrass rivers and streams. The latter were chosen to represent water sources varying in quality from extremely poor to good. Selection was based on the sources and magnitude of pollution, and the diversity and density of piscine populations. Cultures were maintained in vitro, using 12-hour changes of water.

Averaging data for all 9 animal species, egg hatchability (embryonic survival) ranged …
