Location Analysis Of The Recycling Drop Off Program In Knox County, Tennessee, Carol Michelle Donoghue

Masters Theses

This study examines the drop-off recycling program in Knox County, Tennessee, in order to evaluate the convenience of the drop-off site locations. Measures of convenience were distance, level of recycling participation, and location of the site. Surveys were administered to 461 individuals participating in the program at the three Convenience Centers with drop-off recycling facilities. The spatial analysis compared the drop-off locations to the development patterns of the surrounding area.

The survey results indicate that more people are recycling now than before the beginning of the drop-off program. More than half of those surveyed recycle at least once a week …

The Effects Of Urbanization On A Portion Of The Portage Creek Watershed: A Case Study On Surface Water And Groundwater Quality, Susan E. Rezek

Masters Theses

The surface water and groundwater quality in the study area of the Portage Creek watershed was analyzed to determine the possible effects of urbanization. Dry weather and wet weather surface water and groundwater samples were collected from June 1986 to November 1986 at selected stations in the watershed.

Water samples were analyzed for 26 inorganic and organic parameters. Most concentrations were below analytic method detection limits. The analytical data indicate that sodium and chloride are the principal contaminants resulting from urbanization. The probable source of the contamination is deicing salt applied to the City of Portage, Michigan streets.

Overall, the …

A Study Of Periphyton, Sediment And Diatom Community Structure As Monitors Of Heavy Metal Pollution In The Embarras River And Brushy Fork, David L. Vaultonburg

Masters Theses

The purpose of this study was to evaluate periphyton (diatom) and sediment heavy metal content and diatom community structure as potential monitors of heavy metal pollution in the upper reaches of the Embarras River system. The study was initiated due to recent industrialization in the area which could potentially contribute to the present heavy metal burden of Brushy Fork and the Embarras River. These streams are already subject to agricultural runoff, wastewater plant effluent, landfill leachate and other miscellaneous urban and highway runoff. The Embarras River system drains an area of approximately 2800 square miles in 11 east-central Illinois counties …
