World Water Special: How to Decide on the Quality of Drinking Water

There was a time when drinking wells, standing in the wells and drinking water without any thought. But today, it is thought that water is worth drinking, even if it is colorless, odorless, and odorless. How much better it would be for someone to decide on the quality of drinking water instead!

However, there are no universally recognized and accepted international standards for drinking water quality. Each country has set guidelines for drinking water in accordance with the World Health Organization’s standards for its environment, social, economic and cultural. The Bureau of Indian Standards, the Indian National Standards Agency for Safe Drinking Water Quality in our country, has adopted the ‘Indian Standard, Drinking Water feature’ IS 10500: 2012.

Acceptable limits and permissible limits are given to about 65 units in terms of physical quality units, chemical quality units, toxic substances, radioactive materials, residual water use and pesticide limitations and bacterial quality. Methods for measuring all these components are mentioned in Indian standards (IS 3025 Part 1 to 65, IS 14194 Part 1 to 2 etc.).

So what’s the point of drinking water and how much should it be for all of us? According to the Indian Standard, Drinking Water feature IS 10500: 2012,

– If the value of any particular component in drinking water exceeds the acceptable limit, then that water is not worth drinking.

– Alternative to this water, if we have no other source of water, it is possible to drink more water than the Acceptable Limit and the Permissible Limit.

– If the value of any particular unit of water exceeds the permissible limit, then that water is not suitable for drinking.

To know all this, water quality is mainly tested in three steps. The first is physical quality: these tests indicate qualities that can be detected by the senses. Physical components include color, taste and odor, mud / sludge / turbidity and pH (pH).

The second is chemical quality: these tests indicate the amount of minerals, salts and organic matter in the water. The main chemical constituents of water are: calcium, magnesium, sodium, potassium, iron, bicarbonate, carbonate, chloride, nitrate, sulfate, hardness, fluoride, TDS (total amount of salts dissolved in water), boron, Silver, zinc metals. In addition, heavy metals such as cadmium, lead, mercury, molybdenum, nickel, arsenic, chromium, cyanide, chloroform, bromophores and fertilizers, which are widely used in agriculture, are also present in industrial and industrial mining. These factors can adversely affect human health by drinking excessive amounts of water.

Third is the quality of bacteria: these tests show the presence of bacteria. Near the ground level, biological contaminants are entering the groundwater with bacteria. Vaccines in sewers, watering holes or drip pits can also reach groundwater over time. Infected bacteria, viruses, and parasites in contaminated water can spread the contagious diseases. According to Indian standards, there should be no bacteria (E-Coli, Coliform) in drinking water.

In these three tests, water is only worth drinking if the value of all the components is within acceptable limits. The government’s Rural Water Supply and Sanitation Department laboratories, Public Health Institute quality laboratories, Ground Water Directorate and Ground Water Directorate (GST Water Directorate) are working to determine whether the water you use passes these tests.
