Water is a vital commodity for the life of all living beings but despite its importance, its use is not always without danger. Water in these different forms is exposed to various types of pollution that can considerably degrade its quality. Groundwater generally has stable chemical and bacteriological characteristics; however, its properties can degrade depending on the conditions of development, withdrawal, transport, distribution and storage. The main objective of this work is to assess the health risks due to the conditions of supply and distribution of drinking water through analyzes carried out on fresh water made available to the inhabitants of the city of Kenitra. To do this, we chose to take samples from the Maâmora aquifer and describe the level of its metal pollution. Analyzes of trace elements or heavy metals Copper, Zinc, Iron, Cadmium, Nickel, Lead, Boron, fluoride in the waters of the Maâmora aquifer were carried out by a flame atomic absorption spectrometer. Metal analyzes show that the values are still well below the maximum allowed for boron, zinc, fluoride, cadmium, copper and iron. But the concentrations of Lead range from 45.4 to 185.6 µg/L and are very high to the standard of 10 µg/L. The same for Nickel the measured value 78.9 µg/L is much greater than the standard and poses a serious problem for the consumption of raw water from the Maâmora tablecloth.
