Profiling water quality using the multivariate chemometric method

Water is a jewel of our Earth. Purity of water should be maintained for healthy living. Due to industrialization, the environment is polluted and the purity of water is lost. Various parameters are used for testing the quality of drinking water and for the present study electrical conductivity, pH, TDS, chloride, and total hardness of the ground water at Gerugambakkam industrial area in Chennai, India, have been measured. Our aim is to identify if the quality of tested water is acceptable or not for drinking. As multivariates are present, principal component analysis, a widely used method in chemometry is employed for ground water profiling.
