The influence of urbanization on groundwater quality is a significant concern globally. As urban areas continue to expand and populations grow, various factors associated with urbanization can affect groundwater quality. This could include pollutants leaking through pavements and roadways, inappropriate waste dumping, spills from below ground storage tanks, industrial activity and agricultural runoff from suburban areas. These contaminants can seep into the groundwater, degrading its quality. Additionally, the over-extraction of groundwater to meet the demands of urban populations can lead to the depletion of aquifers and a reduction in water quality. Urban groundwater quality will vary depending on local conditions and management approaches worldwide. The current study examines the groundwater quality in Hyderabad City by analyzing the Water Quality Index (WQI) in pre and post-monsoon seasons over a period of three years, from 2018 to 2020. The significant physicochemical parameters such as Hydrogen Ion Concentration (PH), Total Dissolved Solids (TDS), Electrical Conductivity (EC), Bicarbonate (HCO3-) and Carbonate (CO32-), Fluoride (F-), Chloride (Cl-), Nitrate (NO3-), Sulphate (SO42-), Potassium (K+), Sodium (Na+) , Calcium (Ca2+), Magnesium (Mg2+) and Total Hardness (TH), of groundwater quality are considered to analyze the Water Quality Index for selected bore well locations in Hyderabad City. The groundwater quality index is essential for understanding the relationships among measured points and assessing the overall contamination of groundwater. Assessment of groundwater quality can provide valuable information to stakeholders, including government agencies, water resource managers, and researchers, to understand the varying dynamics in groundwater quality and take appropriate measures to ensure sustainable water management practices in Hyderabad City.
