Because of the shortage of drinking water in some parts of Morocco, people are resorting to the consumption of natural waters. In the majority of cases, those waters pose potential health risks, because few studies focus on their quality. In this regard, our study consists to evaluate physicochemical and bacteriological quality of both types of natural waters used for food by people. A well's water in the region of Ain Chgague, and source's water of Sid Bettare, both located near the Fez city. According to standardized norms, we evaluated the physico-chemical and bacteriological quality of those waters. The physico-chemical quality of those waters is studied by measuring temperature, pH, dissolved oxygen, nitrate, ammonium and total phosphorus. As for the bacteriological quality, is evaluated by counting the revivable germs at 37 °C, total coliforms, fecal coliforms, intestinal enterococci, and sulfite-reducing anaerobes. The results obtained show a difference of parameter values analyzed in water to another. For the physicochemical study, all parameters are conforming to standards. While, the majority of bacteriological parameters studied, far exceed the drinking water quality standards. Indicating a microbial pollution, that represents an alarming health risk for consumers of these waters.
Author Keywords: well water, source water, physicochemical quality, bacterial contamination, health risk.

Abstract: (french)
A cause de la pénurie de l’eau potable dans certaines régions du Maroc, les habitants font recours à la consommation des eaux naturelles. Dans la majorité des cas, ces eaux représentent des risques sanitaires potentiels, car peu d’études qui sont s’intéressées à leur qualité. A cet égard, notre étude consiste à l’évaluation de la qualité physicochimique et bactériologique de deux types d’eaux naturelles destinées à l’alimentation des habitants, une eau de puits localisée dans la région d’Ain Chgague et une eau de source de Sid Bettare, situées toutes les deux près de la ville de Fès. Selon des normes standardisées, nous avons évalué la qualité physicochimique et bactériologique de ces eaux. La qualité physicochimique de ces eaux, est étudiée par mesure de température, pH, oxygène dissous, nitrates, ammonium et phosphore total. Quant à la qualité bactériologique, est évaluée par le dénombrement des germes revivifiables à 37°C, coliformes totaux, coliformes fécaux, entérocoques intestinaux et bactéries anaérobies sulfito-réductrices. Les résultats obtenus montrent une différence des valeurs des paramètres analysés d’une eau à une autre. Pour l’étude physicochimique, tous les paramètres répondent aux valeurs limites fixées par les normes en vigueur. Tandis que, la majorité des paramètres bactériologiques dépassent largement les normes de potabilité de l’eau. Indiquant une pollution d’origine microbienne, ce qui représente, donc, un risque sanitaire alarmant pour les consommateurs de ces eaux.
Author Keywords: Eau de puits, eau de source, qualité physicochimique, contamination bactérienne, risque sanitaire.
