Abstract

The physico-chemical water quality of the Obafemi Awolowo University Teaching and Research Farm Lake, Ile-Ife, Nigeria, was studied over an annual cycle (September 2006 to August 2007) almost 40 years after its impoundment in 1967. This was with a view to obtaining the then current state of physico-chemical water quality parameters with their variations in time and space as well as using some of the data obtained to evaluate the aging process of the lake for the 40 years of its existence. There was no significant (p > 0.05) horizontal variation (i.e. upstream - dowstream) in the physico-chemical characteristics of the lake whereas, Apparent-colour, True colour, Turbidity, Total Suspended Solids (TSS), Total Solids (TS) and Total Acidity increased significantly (p

Highlights

Water is probably the most important natural resource in the world, since without its life cannot exist and industries cannot operate
The results indicated that the lake is suitable for most of its applications with little or no adjustments
Ile-Ife is an ancient town in Southwestern Nigeria in which Obafemi Awolowo University formerly known as University of Ife is situated

Summary

Introduction

Water is probably the most important natural resource in the world, since without its life cannot exist and industries cannot operate. Unlike many other resources and/or raw materials, there is no substitute for water in many of its uses. The immense importance of water in our daily life makes it imperative that thorough examinations be conducted on it for most of its uses. The examinations mostly conducted are under the broad headings viz: physical, chemical and biological analysis. Physical analysis involves measurements of temperature, colour, odour and taste, solids and turbidity. Chemical analyses involve the measurements of cations, anions, nutrient compounds, toxic and non-toxic compounds and, tests for oxygen demands by inorganic and organic substances [3]
