Bromate in Sudanese Bottled Water

Abstract

The objective of this paper is to monitor bromate in bottled water due to the fact that Long-term
exposure to bromate may increase consumers’ risk of cancer(1,3), random samples fromtap waterand different
bottledbrands were analyzed for bromate content and their physical properties. The obtained results revealed that
bromate content exceeds the SSMO ,FDA AND IBWA limits of maximum content not exceeding 10 ppb in three
samples, although two of them were taken from the same aquifer which eliminates the source factor and indicates
that the main reason is the ozonation process employed in the disinfection of water. The study recommended to
reduce ozone quantity and contact time In addition to the avoidance of direct sunlight exposure which will
encourage liquid or gaseous chlorine to generatephoto activation bromate in bromide-containing water.It is also
important to introduce safer technologies like membrane or iron exchange filtration.
