Abstract The sole purpose of this study is tn investigate whether the drinkable (poable) water — in the capital city of khartoum is polluted or not . ln short , the locus oflhis dissertation stems Form and is based upon the problems of water of water pollution. The is thought ol’ because the global attention and concern about potable water poluution is reflected the literature review . Thus, yhis research demands a scientilic approacjh to tackle the problems of water pollution with regard to potable water‘ . This research concertrates on the problems ol’ transporting \vater through pipes and other means , its distribution and strong media , their collective ellects on drinkable water , their impact on human health , as well as assuming polices to the entire roleol monitroring potable water policies , ln other words this elToit seeks the suurance ofpotablc water to reach consumers with least possible pollutants that comply to both the Sudanese and Intemational standard ofwatcr quality . To accomplish this research the data is collected mainly from primary source through questiannaire survey approch , The questionanaire form consist ol‘ filly (Q-) questions _ This questionnire fomi is directed to a sample of \@- - rerspondents — and distributed in a simple random manner to the population ol‘ the city of khartoum . The sample respresents more than \ -Z ofthe linnilics ol'thc said city . To solve the stated problem a descriptive and analytical approach is exercised as a research methodology . The objective ofthe descriptive approach is to carry an exploratory research , The exploratory research reflective and described the art-of the state l'or the existence or norn existence ofpollutation in the potable \vtaerol‘Kl1artoum city . Then , statistical techniques are exercised in this research to describe the existing situation ol‘ potable water .
