Abstract

Recently there has been renewed interest and increased concern by the general public and political leaders over the condition of our nation's watercourses. Therefore, regulatory agencies have in most cases imposed stringent requirements on the quality of treated effluents which are being disposed of by discharging them into our lakes, streams and coastal waters. As a result, new methods of investigating the effects of pollutants on water quality are being developed. This study was undertaken in an attempt to develop a simplified analytical procedure for determining the dissolved oxygen uptake rate of bottom sludge deposits. Studies were made on bottom deposits taken from the lower reaches of the Milwaukee river where it passes through the central business district of Milwaukee, Wisconsin shortly before emptying into Lake Michigan. It was the intent of this study to develop a procedure which would require a minimum amount of time to conduct and which would make use of commercially available laboratory equipment. In addition to the development of an analytical procedure, a second and equally important goal was to establish experimental oxygen uptake rates for the Milwaukee River bottom sludges. Hopefully, these uptake rates will aid in conducting future comprehensive studies of the Milwaukee River, ultimately resulting in corrective action necessary to reduce its polluted state. Throughout this thesis the terms bottom muds, sludges, bottom deposits, and benthal deposits are used interchangeably to refer to the pollutional sediment deposited at the bottom of receiving waters.
