Clean drinking water is one of the most necessities for human beings. It is important for everyone to have access to water that is free from any contaminants. It helps not only maintain good health but also avoid issues like dehydration and stomach infection. But, due to the increasing environmental pollution, it is no less than a challenge anymore. Despite taking many preventive measures, water reservoirs are getting polluted. As a result, there are also chances that the water supplied to your home is not entirely safe for consumption.
Yes, you read it right! Unlike all other foods and beverages, it is not easy to determine the quality of water. The clear signs of water impurity are some kind of change in its taste, smell, or colour. But human eyes cannot see all types of contaminants. There are certain impurities that do not cause any changes to the appearance or taste of water. They can be anything from heavy metals to minerals, bacteria to industrial chemicals. Consuming this water without any treatment can cause various health issues. To avoid all these things, water quality must be tested from time to time and ensure that it is free from any kind of contaminants.
What is Water Quality?
Water quality is a broad concept that is usually described by several indicators. Some of the common ones are the concentration of dissolved oxygen, pH levels, salinity, and turbidity. It helps to determine the suitability of water for a specific purpose. You can do so by checking the chemical, physical, and biological characteristics of water. When it comes to drinking water, the TDS level is one of the most important factors used to check its quality.
TDS stands for Total Dissolved Solids. This value represents the total concentration of dissolved substances in water. There are several sources of TDS in drinking water. Some of the common ones are natural water reservoirs, urban run-off, industrial wastewater, water treatment chemicals, etc. All these things can increase the TDS to a great extent. Elevated TDS levels can not only cause water to taste bitter or salty but also give it an unpleasant smell. So, as a part of water quality analysis, you should also check the TDS level on a regular basis.
Types of Water Testing
There are three different types of water analysis to test the quality:
Physical Test: You can detect physical impurities by seeing, smelling, or tasting. Colour, turbidity, odour, and taste are the parameters included in this type of test.
Chemical Test: Chemical tests help to determine the amount of mineral and organic substances in water. These elements are responsible for affecting the quality of water. Some of the common parameters of these tests include pH, BOD, DO, Ca, Mg, Cl, etc.
Bacteriological Test: Bacteriological tests, as the name suggests, can check the presence of any kind of bacteria in water.
How to Perform Water Quality Analysis?
Due to the deteriorating quality, performing a detailed drinking water analysis is imperative. There are several different water analysis methods used to determine its quality:
In this type of testing, skilled professionals analyse water samples in a laboratory. They perform a series of tests to assess the water quality and determine if it is safe for consumption or not. This water quality analysis includes 3 types of tests: physical, chemical, and bacterial.
At-home Testing Kits
Although professional water testing is convenient and highly accurate, it is also expensive. So, you cannot rely on these methods for routine water quality analysis. This is when the concept of at-home water quality analysis comes into the picture. Nowadays, a wide variety of testing kits are available in the market. By using them you can test the water quality at home. The best thing is that the results of an at-home water quality test kit are instant, so you don’t have to wait for hours.
Equipped with several advanced technologies, modern water purifiers also emerged as a solution. They can remove impurities from water and also perform a routine quality analysis. These water purifiers come with a built-in water purity tester. It helps you ensure that the TDS levels are within the normal range at all times.
