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.
Highlights
Fresh water is a fundamental element for the life of man and living beings
The main purpose of this article is the evaluation of the quality of the drinking water taken from the region of El Gharb, using microbiological and physico-chemical methods to analyze and measure some elements such as: coliforms, Escherichia Coli, pH, nitrates, temperature...the results found were processed by the IBM SPSS software to evaluate the significance
The results obtained from the analysis of escherichia coli, intestinal enterococci and coliforms do not detect these substances in samples from the three years 2017, 2018 and 2019
Summary
Fresh water is a fundamental element for the life of man and living beings. Man needs a very large amount of water for consumption - 25 to 50g of water per kilogram of his weight to live under normal conditions. The microbiological phenomena that exist in drinking water, in particular the presence of pathogenic microorganisms, affect water quality on several levels (taste, odors, etc.)[1]. Climate change is a major factor on freshwater. Several studies and indicators have corroborated that the climate is warming on a global scale. The fourth report (2007) of the Intergovernmental Panel on Climate Change (IPCC) confirms this fact. The fourth report (2007) of the Intergovernmental Panel on Climate Change (IPCC) confirms this fact. [2]
