Comparison of the bacteriological quality of tap water and bottled mineral water

International Journal of Hygiene and Environmental Health, 2008
The bacteriological quality of tap water from municipal water supplies, 20-L bottles of mineral water from water dispensers and samples collected from new 20-L bottles of mineral water were comparatively studied. Total coliforms, termotolerant coliforms, Escherichia coli, fecal streptococci, Pseudomonas aeruginosa, Staphylococcus spp. and heterotrophic

Bacteriological indicators of tropical water quality

Environmental Toxicology and Water Quality, 1996
In a search for appropriate bacterial indicators of tropical water quality using the membrane filtration technique, four bacterial groups were surveyed. Of these, Aeromonas hydrophila, Vibrio species, and fecal coliforms were consistently isolated from the four surface water sources located in southeastern Nigeria.
