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

A Rajasthan village gets to drink sweetwater despite high salinity in its groundwater, thanks to a solar-powered desalination unit.

Solawata, a small village in Jaipur district is barely 10 kilometers away from Sambhar, India's largest saline lake which is a major centre of salt production that produces about two lakh tonnes of salt a year. On our way to the village from Sambhar, we see caravans packed with bright coloured camel saddles parked on the road. In sharp contrast, the villages on the way look dry and dreary with their bleak infertile lands.

1. We are an apartment complex with 320 families and a Aerobic STP of 1,50,00LPD. We have recently started using STP treated water into toilet flushing. Since same water is re-circulated repeatedly, I am concerned that URIC ACID concentration will get higher over a period of time as it never gets eliminated but keeps building up. I fear this may lead to fowl smell in toilets eventually. Please elaborate on this aspect, how to measure URIC ACID, how to reduce it etc. 2.

My borewell is located near to the compound wall. After few days of borewell drilling sewage started to get collected on the nearby plot which is hardly 3 feet from the borewell. We drilled for 200 feet. Water levels in the nearby borewell are < 50 feet. We used casing pipe for 35 feet after that pipe didn't go. Once the water collected in nearby plot the water level in the borewell raised. The level of water in the borewell is almost same as the outside sewage water. When we run the motor the water level in the borewell didn't reduced.

A village affected by fluorosis understands the importance of drinking fluoride-safe water with help from experts.

Shilpi Bai was just 18 when she got married to Magan Singh Solanki in Jamnia village, in Dhar district, Madhya Pradesh. She had dreams in her eyes of a great life ahead. She was healthy and soon became a mother of two children. Her husband was a farmer and she would help him in the field after completing the errands at home. Life was going on, leaving behind some good memories. But as the years passed, she felt as if she was losing her physical stamina. She would feel body ache and pain in her legs, especially in her knees.

Desalination of seawater is emerging as a solution to global water crisis. India, too can benefit from it.

In India, fresh water is depleting fast with the rise in consumption for economic activities. Poor management of water resources has led to overexploitation of groundwater. The World Resources Institute’s March 2016 report said 54 percent of India was water stressed, with scarcity affecting every part of the country except the Himalayan region and the ghats. “Almost 600 million people are at higher risk of surface water supply disruptions,” the report said, attributing water stress to climate change and poor water management.

The video tells the story of the women of Podapathar village in Himgir panchayat in Odisha who, through their collective efforts, managed to improve the drinking water situation in their village.

Women of Podapathar village in Sundargarh district in Odisha have become an inspiration for millions of women in the country now, thanks to their determination to improve the drinking water situation in their village. 

Earlier the women had to fetch water for domestic use at 4 am. The nearest drinking water source was 1 km away. "In 2002, the panchayat installed two hand pumps at Podapathar but the water from the hand pump was not fit for drinking," says Dutiya Kisan, a woman in her 50s.

Heavy metal poisoning is a growing concern in many parts of the country. A new method for removing chromium-6, a highly toxic heavy metal, from waste water has been developed by a group of scientists from India and Ethiopia. They claim it to be low-cost and safe.

The new method uses water hyacinth, a weed known for its ability to spread rapidly over water bodies. It is used for cleansing polluted water bodies owing to its remarkable capacity of absorbing pollutants.
