What types of water exist in the world and what are the differences?

If I asked you what types of water exist in the world, what would your answer be? You will be surprised!

Everyone knows how important water is for maintaining life on our planet, right? 

Along with the oxygen we breathe, water is the most important – and at the same time, most threatened – natural resource today.

But despite water scarcity becoming increasingly more of a reality – in fact, this factor has already started to affect the lives of millions of people around the world – this is not necessarily the central theme of our content today!

As you may have noticed, we started today's text with a somewhat unusual question: what types of water exist in the world and what are the differences?

At first glance, I bet your instinct made you answer “fresh water and salt water”, right? And in a way, you’re not wrong. 

But despite being important for classifying water types, these two classifications are quite general. Under the umbrella of water types, there are some variations that go beyond these two types.

And that’s exactly what we’re going to talk about in today’s text! 

In this content we will better understand what types of water exist in the world and what the differences are between them! 

What types of water exist in the world?

I bet you're at least curious to know more about what these types of water are! 

After all, Earth is not known as the Water Planet for nothing, right? This statement only reinforces the idea that there are several types of water and each of them has its own importance.

But, with the exception of those who work with or study these types of water, the vast majority of us have not learned about the differences that each type of water presents.

But that’s about to change! Next, we’ll explore what these types are together!

Here, we will learn more about the following types of water:

Among them, we have mineral water, drinking water, spring water, brackish water, contaminated water, distilled water, salt water, fresh water, polluted water, domestic wastewater and urban water.

Mineral water

One of the most popular types of water on our list, mineral water can be defined as the type of water that has physical-chemical characteristics that promote various types of benefits to human beings.

These waters tend to be more enriched in mineral salts when compared to others. In addition, they are also classified according to certain criteria, such as their chemical composition, source and medicinal properties.

In the vast majority of cases, this type of water is drinkable.

Drinking water, one of the most famous – and valuable – types of water in the world!

In addition to mineral water, another type of water that is often confused with the previous type is drinking water. The term “drinking water” refers to water that is taken from natural sources and, due to its purity, is intended for consumption by humans and animals.

But in order to fit into this classification, water must meet certain prerequisites – which many of us learned when we were at school.

To be considered this type of water, the liquid must be colorless (completely transparent), odorless (without any type of smell) and tasteless (tasteless).

Furthermore, this water must be sterile (without the presence of disease-causing microbes) and contain certain natural mineral salts.

spring water

Another type of spring that is quite famous is spring water. Commonly coming from an underground source, this type of water usually emerges on the surface.

Due to its origin, this type of water may contain certain mineral and gaseous substances dissolved in its composition.

And it is precisely these substances that determine the type of water, which can make it sulfurous, alkaline, magnesium, thermal, among other types.

brackish water

Another well-known classification of water is brackish water. This type of water – which is most often unfit for consumption – usually has a cloudy appearance and has a murky appearance.

This type of water is commonly found in regions where there are mangroves.

Distilled water

Calm down, it's not the distilled drink you're thinking of!

Distilled water is water produced in a laboratory. Made with the help of a distiller, the main function of this device is to remove salts from the water to leave it pure, without any dissolved substances.

It is commonly used in laboratories, in the manufacture of certain medicines and even in car batteries.

Salt water, one of the types of water that is present all over the world

Another classification present throughout the world is salt water. These are the waters of the oceans and seas around the planet.

As anyone who has ever been to the beach knows, this type of water contains a large proportion of salts, the main one being sodium chloride.

As consumption is not recommended, some countries already carry out a process called seawater desalination, allowing it to become suitable for consumption.

polluted water

The saddest classification on the list – and yet one of the most present in our society, unfortunately.

It is water that is mixed with some pollutant, making it prohibited for consumption, making it difficult for animal life to exist. 

This type of water is commonly associated with rivers that run through large urban centers. One example is the famous Tietê River in São Paulo.

How important is each of these types of water in the world?

With the exception of the types of water that are the result of human action – such as polluted/contaminated water – each of them has its own importance for the world.

Each of these types of water has its own particularities and, consequently, influences the habitat in which they are located in their own way, ranging from supplying cities, our consumption and even maintaining the animal and microscopic life that lives in them.

Conclusion

Pardon the pun, but emphasizing the importance of water is stating the obvious. Everyone knows how essential this natural resource is to our lives. 

Therefore, it is our duty – from us to large companies and multinationals around the world – to take care of such a precious asset and maintain it for as long as possible.

And that includes not polluting or wasting this precious liquid! Future generations – and the planet – will thank you!
