In this study, an effort has been made to evaluate the drinking water quality in both urban and rural areas of Ratia Block, located in Fatehabad District, Haryana. A total of 32 water samples were collected from various villages within the block and analyzed for their physico-chemical properties. These results were compared with the standards set by WHO, ICMR, and BIS for drinking water quality. The parameters tested included pH, total dissolved solids, alkalinity, hardness, chloride, fluoride, calcium, magnesium, among others. The findings indicated that certain parameters such as fluoride, total dissolved solids, hardness, and magnesium exceeded the recommended and permissible limits for safe drinking water. The data suggests significant variation in water quality across different villages in Ratia Block. To ensure safe drinking water for all residents, it is crucial to implement targeted water management and treatment interventions based on these findings.
