Impact of Waste Water on The Physico-Chemical Quality of Water Sources In Bed of Oued Essaquia Elhamra In South of Morocco

Original research

The springs of water in the bed of Oued Essaquia Elhamra object of our study, were chosen to illustrate impacts of entropic
activities on the physico-chemical quality of these waters of springs. The analysis of the situation concerning spring, shows a
rather important potential in quantity of water.However, the physico-chemical quality of the water is very low, characterized by
very high mineralization and constituents at this state a source of degradation of the immediate environment, furthermore the
results of the physicochemical parameters indicators of pollution : COD (chemical oxygen demand), BOD5 (biochemical
oxygen demand over 5 days), dissolved oxygen (DO), nitrate (NO3), nitrite (NO2), ammonium (NH4
+), Kjeldahl nitrogen NTK,
phosphates (total PT and orthophosphate PO4
2-), etc. stipulate that the waters in thesesources are exposed to heavy pollution
expressed by those parameters that exceed standards. In the absence of polluting industry in the city of Laayoune; it appears
that this pollution is mainly due to domestic wastes, washing stations, hospitals and, climatic agents onsedimentary rocks is
responsible for high concentrations of certain chemical elements such (Cl-, SO4
2-, B, Ca2+ ... ).The principal component
analysis (PCA) was performed using average values for each parameter, results reveal the existence of a relatively marked
temporal variation of these descriptors, showing four different stations in groups according to their physico-chemical quality
and the level of contamination by sewage discharges.
