Gis Based Assessment of Groundwater Contamination and Associated Public Health Risks in Dindigul District Tamil Nadu India

Ground water refers to the source of wells, springs and aquifers most commonly for human use in our day-to-day life. This study evaluated the physico-chemical and bacteriological quality of drinking water supplied by the Dindigul District, Tamil Nadu, India assessed the community practices regarding collection and storage of water and determined the human health risks associated with consumption of the water. The toxic harmful substances when entered these water resources affect both ecosystem and human health by causing severe health hazards. In our study we focus on ground water assessment in Dindigul district, Tamil Nadu, India for the contamination by comprehensive monitoring, assessment, and remediation efforts. The area was analyzed by Geographic information system (GIS) which helped us in mapping and analyzing the spatial distribution of contamination. A total of 19 groundwater samples were collected to identify geochemical sources and contamination. Water quality index (WQI) assessment was performed and identified for the poor quality of water which is unfit for drinking purposes. The contaminated ground water caused dengue viral strain which was more prevalent in the area was reported by multivariate statistical analysis.
