Is your drinking water free from contaminants? Is it safe for human consumption? In this post, I am going to discuss the different types of impurities present in drinking water.

Water is one of the most important parts of our life. But we humans play a vital role in polluting this primary source of life with different means. We dump industrial wastes in water, littering plastic into the sea, and doing many other things that either directly or indirectly polluting this precious resource.

Water is an excellent solvent, and therefore, it can dissolve anything that comes in contact with it. Once you are aware of different types of impurities, you must know what impurities does drinking water has.

Types of Impurities In Drinking Water

Overall, there are four main types of contaminants in natural water:

  • Dissolved Impurities: Chances are, that natural water consists of inorganic salts, dissolved organic matter, and gasses.
  • Suspended impurities: The surface of water consists of organic suspended pollutants such as animal body material, oil globules, and vegetables. On the other hand, the inorganic suspended impurities consist of sand, clay, and eroded minerals.
  • Colloidal impurities: It includes clay, organic waste products, amino acids, coloring materials, and silica.
  • Pathogenic micro-organisms: It includes bacteria, algae, fungi, viruses, and so on.

Other than this, the drinking water has many impurities that we should not overlook. We should know the harmful effects of consuming impure water to avoid fatal diseases.

These days, with the advancement in technology, many manufacturers are coming forward with water purifier devices. Also, almost every house nowadays has a RO water purifier to purify the drinking water.

Following are some of the commonly found impurities in our drinking water:

Heavy Metals

You must be aware of lead and mercury as a component of water. There are other heavy metals in the water like arsenic, cadmium, iron, aluminium, copper etc. These are naturally occurring elements but are incredibly toxic.

Pharmaceutical Components

Whatever drug we consume, the kidneys filter them from your body. The kidneys take out all the toxins through urine and give you a healthier body.

The drainage system takes this liquid to the rivers, and eventually, we end up disposing of all the body waste in the most substantial water resources.

In a recent study, researchers have come across the percentage of pharmaceuticals in mainstream waters.

Final Thought

In the end, we will suggest you can use different methods that will help you clear out impurities. There is a unique purification process that will help you eliminate harmful effects that you will get in the water.

The home remedy for removing impurities is to boil the water first before consuming it. However, with the introduction of water purifiers in the market, it has become convenient for you and your family to drink pure water.

We hope the information is helpful for you, and you will undoubtedly take a quick action to help you and your loved ones lead a healthier life.
