Abstract: Ground water quality evaluation in the developing countries has become a critical issue due to fresh water scarcity. Maintaining the quality of water is very essential in order to utilize the resource effectively. The most noticeable impact of climate change could be fluctuation in surface water level and quality. The study was conducted at Coimbatore district to know the impacts of climate change on ground water quality by (WQI) water quality index technique. WQI is important technique for demarcating groundwater quality and its suitability for drinking purposes. The water quality parameters of study area were analyzed for two decades (1994 to 2003 and 2004 to 2013). The Water quality index of the study area varied from 30.1 to 69.7 during pre-monsoon and 16 to 47.4 during post monsoon in first decade, it varied from 57.5 to 83.4 during pre-monsoon and 12.7 to 76.8 during post monsoon in second decade. The results clearly showed that observed water quality was lower in pre monsoon as compared to post monsoon in both decades. The deterioration of water quality during second decade is mainly due to industrialization and low rainfall of the study area.
