DARUL AMAN GROUNDWATER QUALITY ASSESSMENT OF
AFGHANISTAN
Groundwater is the most important natural resource used for drinking by many people around the world, especially in arid and semi-arid areas. Groundwater is the major source of drinking water in rural as well as in urban areas and over 94% of the drinking water demand is met by groundwater. The study was carried out to assess the ground water quality and its suitability for drinking purpose in Darulaman, Kabul Afghanistan. For this purpose, four water samples collected from bore wells of villages of study area were analyzed for different chemical parameters such as pH,total, magnesium hardness, sodium, chloride, nitrate, fluoride, cyanide. The results of analysis carried out showed the following concentration ranges: pH value in this research found from (7.423 to 7.45, calcium hardness from (96.19 to 192.3) mg/L. Magnesium hardness varied from (40.2 to 90.14) mg/L and chloride from (0.02 to 17) mg/L. Values of nitrate concentration varied from (0.5 to 3.5) mg/L and fluoride from (0.22 to 0.41) mg/L., cyanide from ranges (0.002 to 0.007. The study reveals that almost all parameters were exceeding the permissible limits. As per the desirable and maximum permissible limit for fluoride, nitrate, total dissolved solids and chloride in drinking water, determined by WHO standards, groundwater sources are unfit for drinking purposes respectively. After evaluating the data of this study, it is concluded that drinking water of Darul Aman is not potable and there is an instant need to take ameliorative steps in this region to prevent the population from adverse health effects.
