Study of Water Quality Using Multivariate Analysis in Coastal Wetland of Réghaïa, Algeria

The use of CA allowed us to group the six study stations into two groups: Group 1, consisting of selected stations at the lake level and at the two watercourses; Group 2, consisting of the two source stations that represent the cleanest stations. The PCA resulted in two factors accounting for 85.96% of the total variance. The first factor obtained is the mineral and organic pollution, from the geological nature of the land crossed, from domestic, agricultural, and industrial activities (the large industrial area of Rouiba‒Reghaia). The second factor represents the effect of the seasonal variation in temperature.
