The present study was carried out on the assessment of water quality index (WQI) of bore hole water in Tiruchendur. All the analysis was done by APHA (2012) method. Here the result pointed out that pH was recorded maximum as 7.16±0.03 during July and September 2016. TDS concentration was obtained high as 2400±2.000 mg/l during September 2016. TA content was noticed high as 688±2.51 mg/l during September 2016. TH range was high as 800±2.00 mg/l during August 2016. The concentration of Ca was recorded high as 200±1.53mg/l during August and September. All the parameters were exceeded the permissible limit of WHO except pH. pH had a positive relationship with TDS and TA and had a negative relationship with TH and Ca. TDS had a positive correlation with TA, TH and Ca. TA had a positive relationship with TH and CA. TH had a highly significant positive correlation with Ca. The bore hole water was not so good when compared with other South Indian bore hole water. The water quality index indicated that the water was highly polluted by the domestic effluents and sewage waste water. It was unfit for human consumption without treatment.
