MULTIVARIATE DATA MINING TECHNIQUES FOR ASSESSING WATER POTABILITY

Water is required for all living organisms of which 1.7% is available as ground water. Water has no calories or any nutrients, but essential for various metabolic activities in our body.Chemical and physical parameters can be tested for identifying the potability of ground water. Electrical conductivity, pH, alkalinity, Total Alkalinity, TDS, Calcium, Magnesium, Sodium, Potassium, Chloride, and Sulphate of the ground water from three districts: Thanjavur, Nagapattinam and Ariyalur of south Tamilnadu were analyzed. Our aim was to check ,if the ground water from the above areas are potable or not .As multivariate are present , Principal Component Analysis with Data mining technique using JRIP rules was employed for classifying the ground water.
