Water quality analysis:
This water quality analysis presents an overview of physical characteristics of water, chemical substances that are normally present in water and various micro-organisms that affect water quality and cause water-borne diseases. It gives an idea of precautionary measures to be taken to prevent water-borne diseases.
For providing wholesome water to consumers, prescribed standards of water quality are to be followed. An Indian standard of drinking water has been presented in this unit.
For physical, chemical and bacteriological analysis, sampling has to be done. If sampling is not done in proper way, the result of analysis will not be representative one. Handling and collection of water samples for different types of analysis also have been discussed in detail with relevant standards.
