Evaluation of Locally Produced Bottled Water Quality – Sudan

Abstract

This research was conducted to study and evaluate the quality of
some types of locally produced bottled drinking water in Sudan. The
objective of this research is to assess the quality of some varieties of bottled
drinking water and compare the results obtained with the Sudanese standards
and the World Health Organization by conducting chemical, physical and
microbial analyzes. Thirteen newly produced samples were taken randomly from bottled water from some shops in Kosti city, and then some laboratory
tests were performed on them to find out the chemical, physical and
microbial properties. Where the results obtained from the chemical analyzes,
represented in some characteristics, and was as follows: PH (7.2-8.5) mg / l,
total dissolved salts (85-150) mg /l fluoride (0-0.8) mg / l, and chloride (4.8).
-35) mg /l and physical analyzes, that bottled drinking water has no color,
taste or smell, and the turbidity in the range (0-0.53) NTU fully conforms to
the Sudanese specifications and the World Health Organization (WHO). The
results obtained from the microbial tests for intestinal and faecal bacteria
were 0 (cell / 100ml), respectively, and they are also within the permissible
microbial limits according to the specifications of the Sudanese Organization
for Standardization and Metrology and the World Health Organization
