The research analysed water from the Mazouta and Sidi-Lahcen springs in the city of Tlemcen to determine their level of pollution and estimate their possibly of harmful effects on consumer health. The physico-chemical and bacteriological analyses carried out have made it possible to classify these waters as calcium bicarbonate waters, carrying pathogenic germs such as coliform sand Escherichia coli that could trigger gastric diseases, hepatitis or typhoid. Contamination is caused not only by sewage in view of the degradation of the supply channels, but also by chemical fertilizers. Considerable levels of nitrate and potassium have been recorded in Mazouta and Sidi-Lahcen waters, respectively.
