Abstract
This report describes the first results of a study of waste stabilization
ponds in the state of Minnesota. The study was started in July 1989 with
support from the Legislative Commission on Minnesota Resources. Waste
stabilization ponds are considered the most economical and efficient method of
waste water treatment of small communities. This form of wastewater
treatment relies upon the natural ability of a body of water to achieve
self-purification. Self-purification involves the reduction of the bacterial
content, satisfying the biochemical oxygen demands of the wastewater,
stabilizing the organic content) and returning the dissolved oxygen content to
desirable levels. Overall efficiency of waste stabilization ponds is a function
of many interacting processes. The objective of the present study is to gain
an understanding of the important factors and an insight into methods of
stabilization pond management· that would ensure acceptable discharge
standards.
The purpose of this paper is to summarize observations and information
gathered at the Harris ponds during the period of July 1989 through October
1990. The objective of the entire study is to gather enough meteorological,thermal,
chemical, and biological information in order to gain an
understanding of the processes at work in these ponds in order to develop a
water quality model. It is hoped that this model and the understanding
gained from it will be useful to improve the operation and performance of
these ponds. In this paper predominantly hydrothermal (physical) features
observed during the first year of the study are described and analyzed.
This study is being conducted as a cooperative effort between the St.
Anthony Falls Hydraulic Laboratory (SAFHL), University of Minnesota,
Minneapolis, Minnesota, and the Minnesota Pollution Control Agency
(MPCA), St. Paul, Minnesota.
