Abstract

Water for consumption requires excellent physical chemical and microbiological quality. This source of life is one of the most controlled food products. It must not only meet the quality requirements but also must comply vis- -vis a set of drinking water standards and must not contain any microorganism no noise and no substance presents a potential danger to human health. This work was performed in the city of Ndjamena and aims to assess the physico-chemical quality of the water pumping stations of the National Water Company in the city center and boreholes in human motor in neighborhoods peripheral devices. A total of 18 samples were collected including 9 in the city center and 9 others in the suburbs. On each sample were determined physico-chemical parameters potential of hydrogen pH temperature T electrical conductivity turbidity and calcium ions magnesium sulphates fluorides and nitrates. The results extend into the water pumping stations of ETS and manual drilling outlying districts respectively temperature 28.0 to 36.1 C and 29.5 to 30.3 C pH 6.5 to 8.5 and 6.3 to 7.6 electrical conductivity 201-671 26297S cm and 136-533 26297S cm turbidity NTU from 0.01 to 0.18 and 1.25 to 5 NTU calcium 54 to 268 mg L to 65-443 mg L magnesium 2.18 to 57 mg L and 15 to 90 mg L sulfates 2 to 47 mg L and 2 to 18mg L fluoride 0.0 to 0.61 mg L and 0.12 to 0.98 mg L and nitrate 1.5 to 18 2 mg L and 0.1 to 0.6 mg L. The results show that the contents of the parameters are consistent with the WHO standards for the quality of drinking water except calcium ions which their levels are high. Based on the parameters analyzed the quality of water pumping stations of SNE and manual drilling is acceptable.
