Abstract:
This study was carried out in Sudan University of Science
and Technology{SUST} in Western and Southern parts
from April to September 2011. The objective of this study
was to evaluate bacteriological analysis of community
water supply system at {SUST} community using
presence absence method.
Fifty water samples were collected from SUST, nine
samples from Locally made cooling system, thirteen
samples from coolers and twenty eight samples from hot –
cool refrigerator.
Samples collected from Locally made cooling system
showed coli-form 8(88.9%), thermo-tolerant 7(77.8%),
presumptive test positive 6(66.7%) and confirmed
E.coli5(55.6%). Samples collected from coolers showed
coliform 3(23.1%), thermo-tolerant 3(23%), presumptive
test positive 3(23%), and confirmed E.coli1(7.8%). Water
samples collected from hot-cool refrigerator showed
coliform 23(82%), thermo-tolerant 17(64.3%),
presumptive test positive 7(25%), and confirmed
E.coli7(25%).
These results strongly alarm the community of {SUST}
and being at critical health risk.
