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

I am from central Chennai and groundwater level in our area has drastically reduced, wo have to depend on other sources (Lorry and Metro water). Metro water often gets polluted so we are looking for control valve open/close by observing the flow through hand pump before letting it to the sump. The challenge here is metro water line to the sump is some 8 feet deep and we don't have proper provision to get down. Can someone please advice if we can have some control valve above the ground level by any means ?

While crores of rupees have been allocated for cleaning up Ganga, the river continues to flow filthy.

As the Ganga emerges from the glaciers and glides along the foothills of the mighty Himalayas through the towns and cities with their sprawling ghats, engineered embankments, hydroelectric dams, and interrupted flows at barrages, the icy chilliness of its waters is lost. Pilgrims swarm its bank to pay obeisance to the holy river but the river continues to be treated as a dump yard for human waste, dirt and rubbish.
