In order to safeguard the health of the people, drinking water must meet quality standards. The main issues involved in drinking water safety are water quality management, surveillance and control mechanisms.
Levels of contaminants need to be ascertained through standard procedures. Each agency involved in water supply in India, has its own laboratory test practices and this manual details methods for all parameters adoptable by all laboratories.
Basic aspects of laboratory set-up and analytical methods for regular testing and surveillance of drinking water quality (SDWQ) are described. It describes various aspects of organisational structure of the laboratory, roles and responsibilities, staff management and training.
Two generally applicable methods for analysing all the essential parameters for drinking water quality testing are described. The testing procedures of all parameters which are monitored as per BIS Standards for drinking water and analytical methods for typical situations are provided.
This information in this manual will improve and support the quality of data generated by water testing laboratories. The recommendations provided are suggestive and aimed at easing the water quality problems in India.
