Assessment of Drinking Water Quality at Source and point of use

Abstract

The study examined the quality of drinking water in the Al-Azhari area South of Khartoum. To achieve this goal, samples were collected from twelve sites to represent the source of the water, the wells and the final use points in the houses (tap water). Standard methods were used to collect, prepare and analyzing samples by using advanced measuring instruments and statistical methods for some important chemical, physical and Bacteriological factors , and compare results obtained by Sudanese standards and World Health Organisation WHO. From the study, all the studied water properties were within the allowed Sudanese specifications except the total count of bacteria, which showed that the groundwater sources and networks are microbiologically contaminated except the Al-Salma block 3, Al-Azhari wells for blocks 2 and 9, and the Al-Bohaira well, which requires treating the source and improving the water supply network. The study showed a positive correlation between sodium levels and total dissolved solids.
