Water quality testing is an important part of environmental monitoring. When water quality is poor, it does not affect only the aquatic system but also the surrounding Eco-system. However, it is directly associated with human health. These quality parameters are physical, chemical and biological. These parameters are not only restricted with portable water but also applicable on ground water, industrial effluent and sewage, only their range may vary. Therefore, the objective of bringing out such a volume is to provide deep knowledge about the environmental significance of parameter, reagent preparation and different method of analysis for a particular parameter.
