What are common water testing parameters?

Common parameters of water testing depends on the purpose of assessment, the purpose can be variety like fitness as drinking water, agriculture use, wastewater treatment performance, discharge requirement as per the pollution control boards or regulatory bodies or national discharge standards, boiler water, cooling tower water, swimming pool, RO plant design, groundwater contamination assessment and many others.

What is the water testing required as per drinking water standards as per IS 10500:2012?

This Indian Standard (Second Revision) 10500 was adopted by the Bureau of Indian Standards, after the draft finalized by the Drinking Water Sectional Committee had been approved by the Food and Agriculture Division Council. The standard was first published in 1983. According to a report jointly prepared by the World Health Organization and the World Bank, approximately 1,230 million people lacked access to safe water supplies in 1975.
