On the Earth’s surface up to 70.8% is water, of which the ocean accounts for about 96.5%. Water exists in many different forms. Water exists in the air as a gas, in liquid form in ponds, lakes, rivers, streams, seas, etc. Water exists both in the soil in groundwater or in soil moisture. Water is very important to our life. But not everyone understands about water especially natural water. What is natural water? Should I use natural water? To clarify issues related to natural water, today’s article will provide you with some relevant information.
What is natural water?
First we will learn the concept of natural water. In simple terms, natural water is water that is available in nature. Examples for natural water are: water in ponds, lakes, rivers, streams, rainwater,… Besides, Water is also formed underground.
Then we see that there is a lot of water around us. Not only is there much, but natural water also plays a very important part in our daily life. From eating, drinking, bathing, growing livestock, economic activities, etc., all need water.
Natural sources of water
Water is so abundant in nature, what sources does water have in nature? In nature, water can be divided into three main types: rainwater, surface water, and source water.
Rainwater is water that is born from a natural phenomenon, which occurs when water vapor condenses in the sky in the form of clouds. Rain is an important phenomenon in the water cycle. This has a strong, direct effect on the deposition of water on Earth. This is also an important phenomenon in the development of ecosystems. At the same time, it is also an important factor of hydropower and irrigation plants.
Rainwater is as clean as we think? In the composition of rain water contains E.coli bacteria (Escherichia coli) and some other bacteria. The inclusion of these bacteria is due to dust in the atmosphere during condensation accidentally mixed in. In addition, rainwater also contains impurities in the air such as NO2, NH3, H2S,… In addition, there are wastes from factories and enterprises such as SO2, CO2, CO, etc.
Surface water accounts for 3% of fresh water and is used by humans in daily life. This type of water is easy to find because it exists on the surface of the Earth. Surface water includes ponds, lakes, rivers, streams, seas, and oceans.
The composition of this type of water depends quite a lot on the surrounding environmental factors. One of the factors must be mentioned as its downstream, upstream. In other words, the composition of surface water can depend on where it flows.
Surface water can be lost through evaporation or seep into the soil to become groundwater. This is also part of the water cycle. In addition, this soil is also absorbed by plants in the process of transpiration or used by humans for daily life or economic activities.
With this type of water, there are soluble gases or organic substances. Groundwater also contains an ecosystem from plants, animals, algae to unicellular and multicellular organisms.
Groundwater is water that is stored in the ground, this is fresh water that is contained in the pores of the soil or rock. Groundwater sources are usually accessed through wells and when surface pressure is too great, this water will be pushed up to form trenches, crevices or freshwater springs. Depending on the depth of groundwater, it can be divided into different types.
Groundwater in the deep layer will usually be located in the rock layers separated from the above, so it is difficult to escape. This can be said to be a source of water providing domestic water for many countries. Therefore, it can be said that groundwater has a great influence on the living environment of humans.
This type of water can be completely polluted or palatable due to salinity, alum, Fe, Mn and some other metals. The inspection and testing of whether groundwater is safe or not requires an investigation and exploration.
The characteristics of water
Water is a chemical compound of oxygen and hydrogen, which is an important substance in the sciences and life. The Earth’s surface area is covered by 70% water. However, only 0.3% of it can be exploited and used as drinking water.
Water will usually be found in liquid form. However, in nature, water also exists in gaseous and solid states and even in ice.
Pure water has physical properties such as colorless, odorless, and tasteless. However, for natural water such as water from ponds, lakes, rivers and streams, different substances can be dissolved, so it will have an odor, color and taste. And of course, depending on the dissolved substances, the color, smell, and taste of each source will not be the same.
The color of natural water will usually be determined by the suspended solids in the water or by the color reflection of the sky. This means that depending on the angle of refraction and reflection of the incoming light, the natural water color will be different.
Substances found in natural water
To better understand what natural water is, next we will learn together about the substances present in natural water. Natural water sources in different places will have different compositions of substances. However, the most common will still have some substances as follows:
In general, the water will have some metals, minerals, inorganic substances, organic matter and microorganisms. The specific evidence is that sulfur and iron present in natural water can affect the taste and color of water. In addition, there are many other types of solids that are also present in natural water such as: Fe, Mg, K, Ca, Cl2, H2, SO2, … In addition, there are CO2 dissolved in water and through some reactions. response.
Not stopping there, there are some suspended solids or dirt in the water. These are typical water-insoluble solids such as dust, sand, rust, etc. These substances also contribute to the unique color of natural water.
An indispensable component in water is microorganisms. This is the common name for bacteria, viruses, germs, eggs (cysts) and several other pathogens. Natural water can be considered as a breeding ground for these microorganisms. One of them must be mentioned as E.coli bacteria or Coliform bacteria group.
In addition to solids that are insoluble in water, there are also soluble salts or some dissolved substances. These substances will not be removed from the water source by simple filtration.
Should you drink natural water directly?
One of the main and most important points in today’s article is whether natural water can be used directly or not. As mentioned above, although the amount of water on Earth is very large, only 0.3% of the total can be used. So Not all natural water we can use directly.
One of the reasons for not being able to arbitrarily use natural water directly is not clean enough. Through the substances in natural water just mentioned above, we can see that not all of those substances are beneficial to health. At the same time, in natural water also contains disease-causing factors. If used directly, it can lead to digestive and intestinal diseases or lead to symptoms such as diarrhea, nausea.
If you want to use natural water, it is best to filter water by physical methods. This will help remove water-insoluble substances. At the same time, you should boil water before drinking to destroy disease-causing factors. And if it is not an emergency, you should not use natural water directly.
To be safe for your health, you should use water that has been sterilized and treated in a clean way, such as bottled or bottled water. There are also types of water that are being encouraged by scientists as well as the government, such as alkaline ionized water.
Above is some information about what natural water is, what is natural water, how many types are there and whether to use natural water directly. Through this article, I hope you can understand more about natural water, the composition of natural water. Natural water however has many such as exist in it is a lot of impurities. Therefore, measures should be taken before use.
