  1. Comparison of the microbiological quality of water coolers and that of municipal water systems.

    Article - En anglais

    The microbiological quality of tap water and that of water from 50 water coolers located in residences and workplaces were comparatively studied.

    In addition, different factors that might influence the bacteriological contamination of water dispensers were examined.

    Aerobic and facultative anaerobic heterotrophic bacteria, total coliforms, and two indicators for fecal contamination (fecal coliforms and fecal streptococci) as well as three types of pathogenic bacteria (Staphylococcus aureus, Pseudomonas aeruginosa, and Aeromonas spp.) were enumerated.

    It was found that 36 and 28% of the water dispenser samples from the residences and the workplaces, respectively, were contaminated by at least one coliform or indicator bacterium and/or at least one pathogenic bacterium.
