Renowned water evangelist, A S Jose. shares his insights on Water - dubbed by some as the new oil. This weekly post, a first in a series of many, aims to break down the basics for the common man.

We have to work towards ensuring the quote while becoming a reality quite rapidly is delayed to the best of our abilities.
Water in all its forms reaching human beings carry impurities. How and why?
Water is a compound consisting of two hydrogen atoms bound to one oxygen atom in a molecule which has a formula (H2O). In its liquid form pure water is transparent, colourless, odorless and tasteless with neutral 7.0 pH and near zero electrical conductivity .
While falling from the sky as rain or snow, it starts picking up impurities from the air dissolving some of the dissolved gases especially Carbon Dioxide (CO2) which reduces the pH (<7.0, acidic) and increases the Conductivity of water; the latter a measure of the dissolved solids.
Insoluble particles including bacteria are carried as suspended matter, though it may not be visible to the naked eye. Rain drops and melted snow percolates through the soil picking up more minerals becoming ground water, while most of the rain water runs off in to lakes or flows through rivers finally reaching sea as surface water.
Water gets contaminated in all its pathways, but through evapotranspiration returns as showers of fresh water as rain and snow as depicted in the water cycle picture below
Energy from the sun falls on soil and water surfaces leading to evaporation assisted by winds, while significant quantities of water is discharged in to the atmosphere by plants by transpiration.
This reverse flow of invisible water vapour in to the air by evapotranspiration is pure water. All contaminants (suspended and dissolved solids and micro organisms ) are left behind the water bodies on earth!
Life on planet is supported and sustained by this amazing water cycle. Nevertheless, the water in the bottle or tumbler in your hand may not be safe to drink.
Water availability and quality are under threat and it is not a matter to be taken for granted. Drinking water has to be tested like a sophisticated industrial product. which must meet the broad WHO Guidelines for Drinking Water Quality (https://www.who.int/water_sanitation_health/water-quality/en).Its 4th Edition (2011) is currently in force.
Water Quality Standards are formulated by each Country or Water Supply Authority giving due consideration to the local conditions and complying to the WHO Guidelines for Drinking Water Quality. Despite all regulations and knowledge you may be apprehensive of the quality of water reaching you.
When in doubt, the least you can do is to boil the source water for at least three minutes.
Watch out to learn more about impurities in water and how to deal with your problems and for solutions apart from boiling water.
