Quality, Standards and Testing

Water needed for human consumption, industrial purposes or other requirements must cater to certain minimum standards. The quality of any water is defined by its physical and chemical properties (characteristics). Physical properties include its appearance (colour, clarity and odour, perhaps also its taste) while the chemical properties refer to the constituents dissolved in it. Some of the physical properties are measurable and can be expressed in units of measurement while others like appearance, odour or taste are clearly subjective. However, all the chemical constituents can be measured accurately.

Drinking water must meet certain quality standards to safeguard the health of the people. The permissible and desirable limits of various parameters in drinking water have been detailed as per the Bureau of Indian Standards (BIS) standard specifications for potable water. These parameters are included in BIS-10500-1991. The various parameters covered include colour, odour, pH, total dissolved solids, hardness, alkalinity, elemental compounds such as iron, manganese, sulphate, nitrate, chloride, fluoride, arsenic, chromium, copper, cyanide, lead, mercury, zinc and coliform bacteria. The tolerance limits for inland surface waters for various classes of water use have been published by the Central Water Commission. Per ISI-IS: 2296-1982, the tolerance limits of parameters are specified as per classified use of water depending on various uses of water ranging from Class A to Class E.

What does the water that one drinks contain, what substances are dissolved in it and what are their safe limits? What are the issues that affect water quality? For more detailed information on all this, please read our FAQs on Rules, Regulations & Standards concerning water and Equipments used to measure water quality and quantity

Regulations for water use, innovation for treating antimicrobial resistance and monitoring of infected plastic leakage needs to be prioritised to curtail the water crisis.

While the world has got a reprieve from pollution with emerging wildlife, cleaner air and clearer water bodies during lockdown, Covid-19 might actually be worsening the present water crisis in an inconspicuous manner. The world is still developing more clarity on safeguards that can prevent transmission, treatment and post treatment complications. This uncertainty has led to the haphazard use of natural and manmade resources that has greater environmental consequences than initially assumed.

A study from Maharashtra found that piped water supply did not ensure access to safe water. Intermittent water supply and poor sanitation triggered water contamination and antibiotic resistance.

While Covid-19 has brought forth the need for better access to water for WASH practices to the forefront, how India plans to bring water at the doorstep through the Jal Jeevan Mission (JJM) continues to be a challenge. This is especially in the context of not only access but also quality of the available water. Studies show that improved water sources  continue to provide unsafe drinking water in low resource settings in India where water borne diseases continue to be rampant.

A workshop highlights the need to give a boost to affordable household water treatment and storage technologies.

India has the most people in the world without access to safe drinking water (133.9 million). Many studies indicate that poor and marginalized populations are the worst affected from waterborne diseases resulting from the consumption of contaminated water. The issue warrants urgent attention as each year over 140,000 children under age five die from diarrheal diseases alone.
