A Survey Of Source And Finished Water Supplies For Giardia Cysts And Cryptosporidium Oocysts, Lisa Martin Sexton Dec 1994

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 …


Use Of Riparian Vegetated Filter Strips To Reduce Nitrate And Fecal Contamination In Surface Water, Mark S. Coyne, Robert L. Blevins, Rebecca A. Gilfillen Oct 1994

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 …


Bituminous Fly Ash Release Potential Modeling And Remediation Of Arsenic, Boron And Heavy Metals, V. P. Evangelou Jan 1994

Bituminous Fly Ash Release Potential Modeling And Remediation Of Arsenic, Boron And Heavy Metals, V. P. Evangelou

KWRRI Research Reports

In Kentucky, approximately 3 million tons of coal fly ash are produced annually at a disposal cost around $20 per ton. Moreover, disposal is becoming a major issue because of the ash's potential to contaminate surface and groundwater with arsenic, boron, heavy metals, etc. Knowledge on the chemistry of fly ash is essential in developing a methodology that can predict release rate(s) and concentration(s) of chemical constituents of environmental concern (pollutants). Currently, there is major concern in the state how to dispose of safely the fly ash generated from the combustion of coal by electrical generating plants. Safe disposal of …

Pathway Analysis Of Contaminant Fate And Transport For Generic Soil Standards And Application To Kentucky Underground Storage Tanks, Paul M. Mcginley Jan 1994

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 …


Kentucky Municipal Wastewater Treatment Plant Sludge Survey, J. Keeling, Paul M. Mcginley Jan 1994

Kentucky Municipal Wastewater Treatment Plant Sludge Survey, J. Keeling, Paul M. Mcginley

KWRRI Research Reports

A survey of solids removal from municipal wastewater treatment plants in Kentucky was conducted by the Department of Civil Engineering at the University of Kentucky. The survey was made using both a mailed form and a followed up phone communication through a period from June, 1993 to April, 1994. The results of that survey were compiled using a spreadsheet program and are available on diskette from the authors. The results of the survey are also presented in the eight Tables herein.


Evaluation Of Solids Generation In Lagoon Treatment Systems: Application To Bardstown, Kentucky, Paul M. Mcginley Jan 1994

Evaluation Of Solids Generation In Lagoon Treatment Systems: Application To Bardstown, Kentucky, Paul M. Mcginley

KWRRI Research Reports

This report summarizes the results of a study which investigated the sludge accumulation in lagoon systems through both literature review and evaluation of the Bardstown wastewater treatment plant. Much of the information in this report has been presented in more detail in the Master's thesis of Jon Keeling (Keeling, 1994).


Kentucky Municipal Wastewater Sludge: Generation, Management And Pathogen Reduction, C. Oligee, J. Keeling, Paul M. Mcginley Jan 1994

Kentucky Municipal Wastewater Sludge: Generation, Management And Pathogen Reduction, C. Oligee, J. Keeling, Paul M. Mcginley

KWRRI Research Reports

This document was prepared as part of an investigation into sludge quantities and pathogen reduction. It has been written as an introduction and reference for operators, municipal officials, engineers and regulators as they assess their sludge management options.


Municipal Wastewater Sludges: Solids Generation And Pathogen Reduction, C. Oligee, J. Keeling, Paul M. Mcginley Jan 1994

Municipal Wastewater Sludges: Solids Generation And Pathogen Reduction, C. Oligee, J. Keeling, Paul M. Mcginley

KWRRI Research Reports

The qualities of sludge generated and the variations in potential processing technologies for pathogen reduction pose a challenge to those evaluating sludge management. Some of the key factors that should be considered when evaluating sludge management options include:

  • Land requirements
  • Equipment requirements
  • Availability of Required additives
  • Desired product end use

The extent to which these factors influence the implementation of a particular processing technology will vary, but in all cases, they will influence the cost and application of any of the technologies.
