Etude géologique et qualités physico-chimique et bactériologique des eaux thermales de la source "Ain Hamra" de la Province de Taza (Rif Oriental - Maroc)

Abstract

The Moroccan thermal spring of Ain Hamra is located 1 km from the provincial road connecting Aknoul to Bourd and a few kilometers  from Ajdir (Province of Taza). It’s used by many curists for its healing properties. This study aims ahydro geochemical and bacteriological analysis of Ain Hamra waters to determine the correlation between the geological structure and the physicochemical composition and to prevent the health risk related to the use of these waters. This study showed that this water is particular by high iron and carbon dioxide  content, and its high natural mineralization. The tectonic analysis by computer processing of the faults allowed deducing the emergence  fault, the origin of the CO₂ which is infracrustal as well as the iron resulting from the waters of the basement alteration cuirasses and the  metamorphic rocks (FeCO₃). The results of the bacteriological analyzes of Ain Hamra spring waters, showed the total absence of the  germs responsible of the nonconformity of the waters and revealed that these waters are of excellent bacteriological quality.
