Hydric pollution assessment generated through the petrochemical industrial zone in the Skikda region (North-East Algeria)

In this study, we carried out a diagnosis of the quality of the wastewater discharged from the Skikda industrial zone, compared with three control points, in the natural environment.The study has been conducted over two consecutive years and on a regular basis, monitoring 10 selected stations and 19 characteristics, giving a total of 4,560 analyses.The measurements show a very pronounced degradation of the quality of the wastewater of the 7 selected complexes with accentuated chemical and hydrocarbon pollution.The statistical approach adopted allows us to group the stations studied into 5 homogeneous groups, with a similarity level of 96.84%.This approach provides some information on the industrial activity influence in the Gulf of Skikda on the immediate environment (Oued Saf-Saf and Mediterranean Sea) with consequences and impacts on environmental quality in the region.
