Water is one of our most precious resources. It is crucial for our physical as well as mental well-being. But one of the parameters that is as important, and one we often tend to overlook, is the quality of the water. Due to widespread pollution and industrialization, our water bodies are severely strained and polluted. This makes it imperative for us to test the quality of our source water before we consume it. Drinking contaminated water can lead to a host of waterborne infections, which can often be fatal. This is where water testing becomes important. It tells you the levels of contaminants present in your water so that you can take steps to correct it.
