Abstract
Hydrogeochemical data pertaining to thirty five groundwater samples in Nanjangud Industrial area were considered in this research work. The water quality parameters were analyzed for physico-chemical characteristics and correlation analysis was used as a statistical tool. Analysis of groundwater revealed that the parameters like EC, TDS, hardness and chlorides in many sampling points exceeded the limits of BIS Standards. EC varied from 0.4 – 12.7mmho/cm and hardness varied from 112 to 2545 mg/L as CaCO3. The correlation matrix clearly indicated that EC was mainly controlled by, TDS, Chlorides and Hardness in a sequence with high positive correlation(> 0.7). Acidity and Sulphates of the ground water samples indicated negative values of Kurtosis (flat peak). The skewness values for the parameters of concern were positive, indicating that data were distributed in the right direction of the tail. It can be concluded that the results of physico-chemical and statistical analysis depicted the deterioration of groundwater in the Nanjangud Industrial area.
