A study of the microbiological and physico-chemical quality of drinking water intended for human consumption in the town of Kenitra

Abstract

The quality of drinking water is highly dependent on physico-chemical and microbiological characteristics. This study envisaged to determine the physico-chemical and microbiological quality of the water consumed by the population of the town of Kenitra by analyzing the following parameters: Conductivity, Turbidity, Temperature, pH, Sulphates, Cadmium, Selenium, Arsenic, Fluorides, Total Iron, Manganese, Chloride Ions, Nitrates, Nitrites, Cadmium, Boron, Nickel, Trihalomethanes, Ammonium and Potassium Permanganate. On the other hand by analyzing the following microbiological parameters: Escherichia coli, intestinal enterococci, coliforms and revivifiable microorganisms at 22 ̊C and 37 ̊C. In general, biological contamination was not detected in the samples collected from Kenitra. At the same time, the results of some physico-chemical elements do not also show contamination in drinking water, which implies that the concentrations of these elements are perfectly in line with WHO requirements.Indeed, the physico-chemical parameters that were considered non-compliant in this work are temperature, pH, dissolved O2 and sulfate (SO42-) represent an impact on water. The results obtained were found to be below the values required by the Moroccan standard.
