Water is a chemical compound with the formula H2O, in which two hydrogen atoms are covalently bound to a single oxygen atom in each molecule.

It is extremely important to animals and plants, as they utilize it for a variety of purposes. Some even go so far as to argue that “water is life.”

Potable Water

The term “potable water” refers to water that is fit for human consumption (i.e., water that can be used for drinking or cooking). The word means that the water is both safe and drinking.

Water that is drinkable is free of unpleasant scents, tastes, and colors, and is within normal temperature limits (Dugan, 1972). Toxins, carcinogens, pathogenic microorganisms, and other health concerns are not present in safe water (US National Academy of Sciences, 1977–82).

Some activities may be impossible to carry out without water.

Water is necessary for life to exist, and everyone should have access to a sufficient (appropriate, safe, and accessible) supply. Improving access to safe drinking water can have a direct impact on one’s health.

Every effort should be made to achieve the safest possible drinking water quality.

Drinking Water Quality ~ an Overview

Safe drinking water and of good quality is acceptable for all common household needs, including personal hygiene

However, higher-quality water may be necessary for some particular applications, such as renal dialysis and contact lens cleaning, as well as for some food processing and pharmaceutical applications.

Due to their vulnerability to organisms that cause infection, those who are severely immune-compromised may need to take extra precautions, such as boiling drinking water because of their vulnerability to organisms that aren’t generally an issue in drinking water

Let’s take a look at the physical and chemical properties of water.

Properties of Water – Qualities of Good Drinking Water

A view of the world from space will reveal it to be blue. This blue color is water; water covers the majority of the world.

We require water for virtually everything, including drinking, bathing, and cooking, therefore we should be familiar with its qualities. Water makes up 65 % of the human body.

Water is necessary for life to exist on this planet. On the surface of the earth, water is spread unevenly. It is a significant solvent that dissolves nearly all polar solutes.

So, let’s take a look at its characteristics and see why they’re important:

Physical properties of water: Water Quality

Water is a tasteless, colorless liquid. Water molecules have a lot of hydrogen bonding, which gives them strange qualities when it’s condensed.

High melting and boiling points result as a result of this. Water has a higher specific heat, thermal conductivity, surface tension, dipole moment, and other properties than other liquids.

These characteristics account for its importance in the biosphere. Because water is a good solvent, it aids in the transfer of ions and molecules needed for metabolism.

It has a high latent heat of vaporization, which aids in body temperature regulation.

Chemical Properties of WaterQualities of Good Drinking Water

Water reacts with a wide range of substances to produce a variety of chemicals. The following are some notable reactions

The oxygen atom in the water molecule has two lone pairs, one of which could form a bond with a proton, allowing the water molecule to act as a base in a reaction. Water is amphoteric because it can act as both an acid and a base.


Acidic Behaviour:              

Basic Behavior:

Redox reactions

Water is reduced to a hydrogen molecule by electropositive elements. As a result, water is an excellent supplier of hydrogen. Let’s take a look at an example in this case:

Uses of Water – Qualities of Good Drinking Water
  •  Water can be drunk/consumed
  • It can be used to wash
  •   It can be used for baths.
  • And it can also be used in cooking
Hydrolysis reaction

Because of its dielectric constant, water has a very strong hydrating propensity. It dissolves a wide variety of ionic compounds and can hydrolyze several covalent and ionic molecules.

Water Resources: Sources of Water

Water covers over three-quarters of the Earth’s surface.

There are two main sources of water;
  • Surface Water

These are the waters that have covered the land’s surface. Rivers, lakes, and other bodies of water

  • Ground Water

These are the waters found beneath the earth’s surface and between rock fractures.

Important fact: Groundwater accounts for 20% of the world’s total water supply.

The cleanest sources of surface water and groundwater must be preserved for potable water supply purposes (Schwartz et al., 1990).

Potable water must meet numerous physical, chemical, microbiological, and radionuclide (q.v.) standards for both the untreated (raw) water sources and the treated water.

Water’s Functions: Uses of Water
  • Firstly, water can be consumed/drunk.
  • It can be used to wash
  • Then, water can be used to take a bath.
  • It can also be used in the kitchen for cooking

What is the distinction between water and other liquids?
  • Other liquids have odors, but water is odorless.
  • Secondly, water is colorless, while other liquids are colored.
  • For example, water is always clear, but liquid soap comes in a variety of colors, including green, yellow, and blue. Coca-cola is black, while Fanta is orange.
  • Lastly, water has no taste, but other liquids do.
