To achieve a better understanding of the nature of the factors influencing groundwater composition as well as to specify them quantitatively, conventional graphical and multivariate statistical analysis (principal component analysis) were applied on hydrochemical data consisting of 51 groundwater samples collected from domestic boreholes in Yenagoa city, Bayelsa State, Nigeria. The mode of study includes analysis of major ion contents and other chemical parameters such as pH, total dissolved solids and electrical conductivity of the groundwater samples. The PCA yielded three principal components explaining 78.38 % of the total variance of the 11 parameters. The three components are interpreted as controlled by the natural weathering of existing silicate rocks, reverse ion-exchange processes and oxidation reactions which are further supported by the scatter diagrams, ionic signatures and mechanisms controlling the water chemistry diagrams as the common factors influencing the groundwater hydrogeochemical character. Limited anthropogenic influence on the groundwater composition has also been noticed in the study area. The groundwater poses no threat to human health because the concentrations of physico-chemical parameters that can be used to evaluate drinking water quality are within World Health Organisation standard specification. The groundwater in the area is fresh, high salinity and low sodium in nature.

“…Le magnésium, avec une concentration moyenne de 3,4 ± 2,1 mg/l, pour un minimum de 0,8 mg/l et un maximum de 9,2 mg/l, est le cation le plus dilué et toutes les valeurs obtenues sont inférieures à la norme OMS (soit 50 mg/l figure 3 illustre l'évolution des teneurs en sodium en fonction des teneurs en calcium dans les eaux souterraines de Yaoundé. On constate sur ce graphique que la diminution des alcalinoterreux se fait au profit des alcalins grâce aux échanges cationiques avec les minéraux argileux de la matrice favorisant une fixation de calcium contre une libération du sodium (Garcia et al, 2002), ceci est corroboré par le faciès sodique obtenu dans les eaux souterraines de Yaoundé. Rôle de la lithologie : L'hydrolyse des silicates est le phénomène majeur d'altération des minéraux primaires des roches.…”

“…Indeed, saturation indexes show that some samples are under-saturated with respect to gypsum and anhydrite, highlighting a geochemical condition dominated by During this process, Na + in the solution is exchanged with Ca 2+ in the sediments. Moreover, the referred exchange is confirmed through the two Indices of Base Exchange (IBE), namely the Chloro-alkaline indices (CAI 1 and CAI 2) (Schoeller, 1965;Garcia et al, 2001).…”
