Groundwater quality and availability are essential for human consumption, domestic and irrigation purposes. Since water quality has a significant impact on human health, it demands compulsory continuous monitoring to ensure water quality. The water quality of Theni district, Tamil Nadu was studied by a field survey for a period of three years (2018-2020). Various water quality indices were calculated and analyzed for the purpose of drinking, domestic, irrigation and corrosivity nature. The analysis of spatial distribution map of domestic water quality index and corrosivity index revealed that north-west part of the area has good water quality. Based on the analysis of spatial distribution map of irrigation water quality indices, south-west part of the study area was excellent for irrigation. The spatial distribution of all calculated water quality indices reported that south-east part of the study area needs special attention in terms of monitoring and sustainable management.
