    Contribution à l'étude de la qualité microbiologique des eaux potables de la région de Ghardaïa

    This study aims to evaluate the bacteriological quality of drinking water distributed in the Ghardaïa region (Algeria) by analyzing 30 samples collected from various municipalities. The analyses were performes according to standardized protocols from the Algerian Water Company (ADE), focusing on key bacteriological indicators, such as total coliforms, Escherichia coli, fecal streptococci, and sulfite-reducing anaerobic spores (ASR). The results show high compliance with Algerian drinking water standards: 100% compliance for ASR spores, 93.3% for total coliforms and E. coli, and 90.0% for fecal streptococci. However, the occasional detection of E. coli and fecal streptococci—sometimes in significant concentrations—indicates recent or persistent fecal contamination, posing a potential risk to public health. These findings highlight the need to strengthen monitoring systems, protect catchment areas, and optimize disinfection treatments. The study also recommends further investigations and a holistic approach combining microbiological, physicochemical, and hydrogeological analyses to ensure safe and sustainable management of potable water resources
