The analytical parameters of wastewater gathered from ten stations have been studied by standard methods. The unpleasant odor was observed in all stations, in addition, the pH of the wastewater was measured to be in the range of 6.3-8, meanwhile, the electrical conductivity of the water was in the range of 2030-6450 μscm −1 . The values of 3225, 406, (144-604), 5.84 and 130 ppm corresponded to maximum total dissolved solids, maximum biological oxygen demand, range of the chemical oxygen demand of the selected sites, maximum nitrate content and maximum sulfate content, respectively. The obtained analytical data showed variables in all used parameters in all stations, and most all of the studied parameters were higher in comparison with the permissible limit reported by World Health Organization or the Libyan National Center for Standardization and Metrology.
