Assessment and comparison of physio-chemical parameters of drinking water of Delhi Region

Pure and safe drinking water is the potion of life. People on the globe are under huge danger because of unwanted changes within the physical, biological, and chemical characteristics of air, water, and soil. Due to the increased human population, industrialization, use of fertilizers, and human activities, water is highly polluted with various harmful contaminants. Natural water contaminates due to the enduring of rocks and leaching of soils, mining processing, and others. The quality of drinking water must be checked at regular time intervals because, because of the use of contaminated drinking wa-ter, the human population suffers from varied water-borne diseases. The accessibility of good quality-water is a vital element for forestalling infections and improving personal satisfaction. It is necessary to know details about various Physico-chemical parameters like color, temperature, acidity, Hardness, pH, Sulphate, Chloride, Dissolved Oxygen, alkalinity used for testing of water quality. Some water analysis reports with physio-chemical parameters have been given for the investigating parameter study. Guidelines of distinct physio-chemical parameters also have been given for comparing the value-of real drinking water samples of Delhi-NCR. Samples were convened from 7 different localities of Delhi-NCR. Now, the data convened in both years 2017 and 2018 were compared. The objective of the research paper is to study the quality of water over time so that we can understand the quality of drinking water every individual is consuming throughout the years in Delhi and other National capital regions.
