Étude de la qualité bactériologique et physico-chimique des eaux de certains puits et sources par l'utilisation d'une analyse en composantes principales (ACP): Une étude de cas de la région de Meknès, MAROC.

The present study aims to investigate the impact of anthropogenic factors on the quality of groundwater in some wells and springs in the region of Meknes, used for the various purpose by the local population. This work was conducted for a duration of 6 months by monthly withdrawal from February to July 2013. The main physico-chemical and biological components of water quality have been measured and a principal component analysis (PCA) was performed based on the average values of each parameter, it was able to reveal the existence of a relatively strong spatial variation of these descriptors, making it appear four groups of very well differentiated and unequal stations: the first two groups together five wells and two springs provide a good quality water or slightly polluted and the last two which contain the other wells where the water is very polluted.
