Chapter 2 Water Quality Analysis Physical Parameter

Abstract

Water quality monitoring is a fundamental tool in environmental management as it provides evidence to support decision-making on health and environmental issues. Water quality refers to the physical, chemical, and biological characteristics of the water. Water quality information will help in the assessment of the current condition and patterns over time and space to understand and manage factors that influence water quality. In this chapter, the physical parameters included in water quality monitoring will be discussed. A physical parameter is one of the essential criteria for water quality analysis. There are 21 physical parameters for water quality monitoring [1]. But this chapter will selectively only discuss seven parameters for water quality sampling: pH, temperature, turbidity, total dissolved solids, total suspended solids, conductivity, and salinity. Most of the physical parameters for water quality are analysed in situ using portable instruments or by collecting samples for laboratory analysis.
