Dans le but d’etablir la correlation entre les resultats des lixiviats du LES et ceux des eaux souterraines (puits et piezos) et de surface (lac), des analyses en composantes principales et factorielles ont ete realisees. Ces analyses permettent d'avoir une vue mathematique exacte de la repartition des points correspondants aux prelevements dans l'espace defini par les facteurs qui sont les elements analyses. L’analyse en composante principale des parametres physico-chimiques et microbiologiques des deux premiers axes de la correlation explique a 68,19% la variabilite du niveau des parametres physico-chimiques et a 75,88% celle liee a la concentration en microorganismes dans les eaux de tous les points echantillonnes autour des lixiviats. La relation entre les parametres etudies des differents points echantillonnes avec les lixiviats, par rapport a la qualite de l’eau, a ete aussi examinee a l’aide d’une analyse factorielle des correspondances simples. Les resultats obtenus montrent que les deux premiers axes de la correlation expliquent a 95, 67% toute la variabilite des parametres de qualite de l’eau au niveau des stations. © 2016 International Formulae Group.

These analyses showed an exact mathematical view of the distribution of the points corresponding to the samplings in the space defined by the factors which are the analyzed elements. The analysis in main component of the physico-chemical and microbiological parameters of the first two axes of the correlation explains at 68,19% the variability of the level of the physico-chemical parameters and at 75,88% that bound to the concentration in microorganisms in the waters of all the points sampled around leachates. The relation between the parameters studied by the various points sampled with leachates with regard to the quality of the water was also examined by means of a factorial analysis of the simple correspondences. The obtained results show that the first two axes of the correlation explain at 95, 67% all the variability of the quality parameters of the water from the stations. © 2016 International Formulae Group.
