Abstract

Groundwater acts as the main supply of drinking water, especially in developing regions. However, rapid industrialization poses significant threats to its quality. This study focuses into the condition of the groundwater in industrial zones of Tirupur District, Tamil Nadu, where accelerated industrial activities have raised serious environmental concerns. A total of 10 sampling locations were selected across key industrial areas, and water samples were analysed for physicochemical parameters during both summer and winter seasons. During the summer, the Water Quality Index (WQI) values varied from 7.14 to 224. and 76 to 210 in winter, indicating that many sites exceed acceptable limits for human consumption. Seasonal variations were assessed graphically, and a correlation matrix was used to explore inter-parameter relationships. Principal Component Analysis (PCA) further identified the dominant pollution factors, explaining 64.84% of total variance in the rainy season and 52.63% in summer. The results highlight a concerning decline in groundwater quality and emphasize the urgent need for sustainable industrial practices and appropriate water treatment interventions.
