Water is a vital element for humans. It is important to have it in sufficient quality and quantity, thus ensuring a healthy and safe life in the long term. According to a report by the World Health  Organization, five million infants and children die each year from diarrheal diseases due to the pollution of food or drinking water. The main objective of this work is to describe the conditions of supplying and distribution of drinking water through an analysis carried out on the freshwater made available to the inhabitants of Sidi Taibi, Kenitra. To do this, we took the sample from eight wells, aiming to describe the physico-chemical characteristics, so we assess the ecotoxicological contamination by the main heavy metals. The physico-chemical analysis showed that the wells studied have lower concentrations l than the values of the Moroccan standard with the exception of nitrate contents which exceed (55.9-69.2mg/l), concerning the metallic elements, we found only traces. As the parameters follow The conductivity; temperature; pH; cations (calcium, magnesium, potassium, and sodium); anions (chloride, sulfate, bicarbonates, and nitrate); trace elements (Iron, Manganese,..) The consumption of drinking water, a determining factor in the prevention of water-related diseases, should receive special attention. In fact, water intended for human consumption must not contain dangerous chemicals or germs harmful to health.
