Description 97-105
Various chemometrics methods were used to analyze data sets of marine water
quality for 9 parameters measured at
34 different sites of Maharashtra from 2007 to
2009 to determine spatial variations in marine water quality and identify
pollution sources. Hierarchical cluster analysis (CA) grouped the 34 monitoring
sites into three groups based on similarities in marine water-quality
characteristics. Discriminant analysis (DA) was important in data reduction
because it used five parameters (DO, Ammonia, pH, FC and temperature) to
correctly assign 96.4% of the cases. In addition, principal component analysis
(PCA) identified three latent pollution sources for organic pollution, industrial
pollution and fecal pollution. Furthermore, water quality index was calculated
based on four parameters viz. pH, DO, BOD and FC.
