Comparative Study of Groundwater Quality of Pune City: Post-Monsoon and Post-Monsoon

This study investigates the variations in groundwater quality in Pune city between the pre-monsoon and post-monsoon seasons. Groundwater is a vital resource for drinking, irrigation, and industrial purposes, especially in the city's periphery where treated water supply is limited. This research examines the impact of seasonal rainfall, runoff, and anthropogenic influences on groundwater quality by analysing key physicochemical parameters, major ions, heavy metals, and microbiological indicators. The findings highlight the importance of continuous monitoring and management strategies to ensure the sustainability of groundwater resources in the face of increasing contamination and environmental changes.
