Impact of Anthropogenic Activities on Vandiyur Lake: An Ecological and Chemical Analysis

This study investigates the environmental and ecological health of Vandiyur Lake in Madurai City, Tamil Nadu, India. GIS mapping reveals the lake’s proximity to residential and commercial areas, contributing to pollution from various sources, including domestic, hospital, and industrial sewage. Chemical analysis shows alterations in the lake’s pH, dissolved oxygen, CO₂, and phosphate levels. The lake also suffers from the overgrowth of the invasive species Eichhornia crassipes. Despite these challenges, the lake serves as a crucial source of groundwater and supports local fishing activities. The study underscores the urgent need for sustainable management practices to preserve this vital ecosystem.This study investigates the environmental and ecological health of Vandiyur Lake in Madurai City, Tamil Nadu, India.
