Water quality evaluation through application of chemometrics for Godavari river at Rajahmundry.
The main aim of this work is focused on water quality assessment of the Godavari river at Rajahmundry and evaluation of pollution data obtained by monitoring during the period August 2003-July 2006. The study presents the application of selected chemometric techniques to the pollution monitoring data set, namely, cluster analysis, principal component analysis, discriminate analysis and factorial analysis. The obtained results allowed determining natural clusters and groups of monitoring locations with similar pollution character and identifying important discriminate variables. On the basis of the chemometric approach, it was found that some locations were under high influence of municipal contamination and industrial effluents, and some other under the influence of agriculture.
