ÉTUDE DU CHANGEMENT DE L’ETAT DES EAUX DE L’OUED KHOUMANE A LA CONFLUENCE AVEC LES EAUX THERMALES DE LA SOURCE AIN HAMMA MOULAY IDRISS MAROC
Journal Title: Larhyss Journal - Year 2012, Vol 11, Issue 11
Abstract
In order to study the influence of the waters of the source Ain Hamma Moulay Idriss on the quality of waters of the ‘’Oued Khoumane’’, companions sampling of waters were determined monthly between August 2010 and July 2011 at two stations on the bed of the ’’Oued ’’ and the other at the source. The descriptive analysis of the results showed that the waters of the river are subject to important physical and chemical variations in the downstream station: enrichment in mineral salts (chlorides and sulfates), increase in temperature, conductivity and hardness Total. With regard to bacteriological contamination, the waters of the river have a high level in terms of fecal contamination (total coliforms, fecal coliforms, fecal streptococci and Enterococci intestinal compared to source waters. The explanatory analysis (Principal Component Analysis) showed variability between stations and corroborated the results of the descriptive analysis. The planning of the source remains a paramount solution to preserve the water quality of the source and that of the ‘’Oued’’.
