In 2015 it is estimated at more than 5,000 inhabitants [KHERIFI et al 2016], but currently this number of population is not fixed in this region because it is a transitory population by their visitors. The local economic system of the entire study area is under developed; the available assets it dispose such as agriculture, livestock, fisheries and tourism are mobilized for informal activities.…”

“…On the cartography plan, our results constitute the first references for the development of a base of the geographical data concerning the probable source of the origin of pollution of the Lake Mellah and its affluents. Pluviometry and salinity are considered as paramount factors of positive purposes of the spatio-temporal distribution of the faecal bacteria on the Lake Mellah and of its affluents [KHERIFI et al 2012;2016]. Thus in rainy period, the streaming of the grounds soils rich in organic manure explains the condensation of faecal contaminants of animal origin on the level of the Lake Mellah.…”

Lake Mellah close to the Mediterranean Sea in north-eastern Algeria belongs to valuable ornithological sites with numerous, often migratory, birds. To achieve the research goal, seventeen (17) sampling points were sampled based on the urbanization of the watershed. Water samples were taken at different wadis levels (upstream and downstream of settlements), as well as at the wastewater treatment plant and in Lake Mellah based on four measurement campaigns conducted at one frequency seasonal (high water, low water) during the year (2011/2012). Biological parameters (coliform faecal bacteria, streptococci) were analysed in water of the lake and its affluents in the laboratory of the Department of Health and Population, El Taref by the most probable number (MPN) technique of the Mac Grady table taken from various points. Obtained results were processed by the use of Bourgeois ratio (coliform faecal bacteria: streptococci) to indicate the origin of faecal contamination of waters and to establish maps of the spatio-temporal evolution of this ratio by the software Surfer 9. This way we obtained information of contamination of human origin during the dry season coming from domestic waste waters. In winter the ratio showed animal prevalence of contamination coming primarily from Animal Park in El Kala.

“…Algeria built a UWWTP behind El Mellah lagoon, but the water quality is still poor with respect to fecal microbes (Kherifi and Bousnoubra-Kherici, 2016). There is an unresolved conflict between the managers of the El Kala National Park and the inputters to this lagoon, mainly industries and farmers (Telailia et al, 2017).…”

“…The deterioration of the water springs quality resulted of human activity constitutes as important a threat as that associated to the quantitative imbalance. In Algeria, population growth accompanied by a rapid urbanization cause numerous perturbations for natural environments [KHERIFI 2016]. In parallel, the industrialization, the unsustainable use of fertilizers and pesticides, and the public awareness lack of environmental protection lead to an ecosystem imbalance and generate pollutants that can affect the receptor aquatic environement's physical and chemical and biological quality (lake, river, marsh, etc.…”

Nowadays, problems with wastes constitute a danger increasingly important for the recipient environments. Indeed, the water is affected in an increasing way by mineral and organic materials from which some ones are pathogenic and thus dangerous for the ecosystem. It is in this context that the present study took place, it relates to the surface waters pollution of the Wadi Bounamoussa in the Algeria northeast. The study concerns the analysis of physical and chemical parameters of waters such as: temperature (T), pH, electrical conductivity (EC), Cl -, chemical oxygen demand (COD), total absorbance colour (TAC), total hardness (TH), PO 4 3-, total phosphorus (P tot ) along the wadi in one year long survey (October 2013 to July 2014). Waters were sampled at ten study sites with a quarterly sampling.In order to establish a relationship between various physical and chemical parameters and for a better assessment the anthropogenic effect on the Wadi Bounamoussa's water quality, we have processed a statistical treatment by means of the Principal Component Analysis (PCA).PCA has revealed two gradients. The first reflects the eutrophication caused by chemical fertilizers used in agriculture and the intensive livestock farming development, while the second describes the resulting water mineralization of high rates of the Cl -and EC. Moreover, PCA has allowed discriminating the stations according to their physical and chemical data. This study has allowed us also to reveal the influence of seasonal variations.
