Abstract:
This study was carried out to assess the bacteriological quality of
ground water in Omdurman, Elthawra Locality.
Fifty-four samples from 18 wells (one sample for each of the three
seasons), were collected and examined bacteriologically to detect total
coliforms, faecal coliforms and E. coli. The method used was Multiple
Tube Method.
The study was conducted during the period from August 2002 to
April 2003 so as to cover the three seasons (Winter, Summer and Autumn)
in Sudan,as spring is not noticed in Sudan.
The study showed that, the ground water quality was excellent in
27.7% of the study area, namely Hara 9(B), 11(B), 14, 23 and 25 which
was evidenced by MPN zero throughout the duration of the study. Other
site showed the presence of total coliforms,. Madinat Elneel (B) (MPN =
11) in Autumn, Hara 4 (MPN = 18) in Autumn and 10(B) (MPN = 13) in
Winter.
Madinat Elneel (A) showed coliforms bacteria during two seasons
(MPN = 20) during Autumn and (MPN =17) in Summer. The other sites
showed good quality of water (MPN <10).
The study confirmed faecal contamination in Riyadh (Hara 8)
during the three seasons of the study. The study found that, there was a
seasonal variation of ground water quality. The high number of bacteria
were detected during the rainy season.
