1.1 Introduction
Groundwater has an excellent microbiological quality and generally adequate chemical quality for most uses. Nine major chemical constituents (Na, Ca, Mg, KHCO3, Cl, SO4, NO3 and Si) make up 99% of the solute content of natural groundwater. The proportion of these constituents reflects the geology and history of the groundwater. Minor and trace constituents make up the remaining 1% of the total, and their presence (or absence) can occasionally give rise to health problems or make them unacceptable for human or animal use (British Geological Survey to Africa).
As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the Aim and Objectives of the study. Others are Significance of the study, Scope of work, Limitations of the Study and Definition of technical terms.
