Title: Assessment of Ground Water Quality in East KassalaTown. Kassala State-Sudan
Author: Elhassan, Rasha Mohammed Elamin
Abstract: Kassala state is one the major states in Sudan, characterized by scarcity in water, the main water supply is underground- water (wells). Design : This study was conducted as Cross-sectional descriptive study. Setting : in East Kassala Town . Objective: to assess the quality of ground water in East Kassala Town during the period from 2/2009 to 2/2010 Methods: 28wells were selected in the study area; 84 Samples of water were collected for seasonal variation (winter, summer, autumn), the samples were transported to the laboratory of Drinking Water Corporation in Kassala to be analyzed for the chemical, physical and bacteriological examination,and sanitary condition around the boreholes. Results: The findings of the study showed that, all Boreholes were safe regarding chemical quality parameters (PH- F- Fe - T.D.S - Hardness -NO3 - NH4-SO4); with concentration within the guidelines of (W.H.O) and (S.S.M.O).The results indicated that the physical quality parameters (conductivity-turbidity ) and the bacteriological analysis of all samples revealed that total coliform and E.coli ( was negative in all seasons ).were within the allowable guideline of (W.H.O) and (S.S.M.O). The sanitary condition around the boreholes shows unsatisfactory and may pose threats to the safety of water wells; 96% of boreholes were located at distance of less 50 m from latrines, which is less than the recommended, and 57% of wells in the study area contamination risk score is high, 43% contamination risk score is intermediate. The fact that the constructional features of these boreholes which is characterised by double filters in their casings . and that most of these boreholes are new can explain the good quality of their water irrespective of their distances however in the future these boreholes might be influenced and hence periodic analysis is required. Recommendation : The study recommends the prevention of ground water pollution; enforcement of laws and regulations effective protection programmer coordination between sectors (government, private, local, others) concerning ground water safety; increasing of public awareness and community participation in water programmers; further studies addressing the subject of ground water pollution focusing on on-site wells used to dispose of the effluent
