Abstract: | This study deals with the application of chemometric approaches (cluster analysis and principal components analysis) to a
potable water monitoring demonstrated on a data set from the region of Kavala, Greece, being analysed according to the standard
instructions and directives of the European Union. It is shown that the data classification by cluster analysis and data structure
modeling by principal components analysis reveals similar results, namely four different patterns of water source sites are
identified depending on the geographical site location (near to Nestos river, near to Strimon river, elevated sites and near-to-coast
sites). Three latent factors, explaining over 85% of the total variance, are responsible for the data structure as follows:
“water acidity (anthropogenic)”, “water hardness (natural)” and the “marine factor”. Their importance for the different sites
is related to the site location. Finally, it is recommended to involve the environmetric data treatment as a substantial standard
procedure in assessment of the quality of water intended for human consumption.
