Water is a necessary component and valuable natural resource that shapes the central constituent of biological community. It is essential for supporting all human activities hence, it’s arrangement in terms of quantity and quality has becomean utmost priority. Contamination of water-sources like streams, lakes and seas influences lives and their regular habitat throughout the globe. This present study is centered on estimating the quality of drinking water in Delhi, India. This study was based onthe analysis of various parameters of drinking water such as physical and chemical. The results of drinking water samples collected from various locations were compared with the standard acceptable limits as per IS: 10500-2012 to check whether the drinking water quality follows the standard, and also to determine its suitability or not for the drinking purpose. 15 drinking water samples were collected from various areas of Central Delhi and examined for different physicochemical parameters. All samples were collected from the diverse Delhi locals. Parameters, such as, pH, Colour, Odour, Taste, Conductivity, Turbidity, Total Hardness, Calcium, Magnesium, Chloride, Nitrate, Phosphorous, etc. were conducted in these samples. As per the resultant of this study, it was concluded that pH level ranges from 6.16 to 7.89 with heavy metals having slight variations between 0.001 to 9.89 including Na, K, and Ni etc. In the study, we found maximum pH value in the Kamla Nagar region that was 7.82 and least in the Karol Bagh region that is 6.66 and both the min and max values lies in between the acceptable limit that is 6.5 to 8.5. pH of the water is the measure of the H⁺ ion activity of the water system. It indicates whether the water is acidic, neutral or alkaline in nature.
