Groundwater quality assessment is crucial for ensuring safe drinking water and sustainable water resource management. This study evaluates the hydro-chemical characteristics of groundwater in Rajahmundry, Andhra Pradesh, using the Water Quality Index (WQI) approach. A total of 15 groundwater samples were collected from different locations and analyzed for key physicochemical parameters. The WQI was computed to classify the groundwater quality into different categories, ranging from excellent to unsuitable for drinking. The results indicate that some samples fall within the permissible limits set by the WHO and BIS, while others exhibit contamination concerns, primarily due to anthropogenic activities such as agricultural runoff, industrial discharge, and improper waste disposal. The findings emphasize the need for continuous monitoring and effective groundwater management strategies. This study provides valuable insights for policymakers and local authorities to implement appropriate measures for maintaining groundwater quality in Rajahmundry.
