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

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

The implementation of the occupational health and safety management system according to OHSAS 18001/2007 in a Moroccan telecommunication company

Integrated environmental, health and safety management systems are a new management paradigm in modern organizations. These systems are built on the ISO 14001 and OHSAS 18001 standards, based on risk prevention and the precautionary principle. The study is carried out in a telecommunications company in Morocco. The objective is the definition of an approach that will promote the protection of its employees against the risks they face and not only prepare them for obtaining safety certification. It has become necessary to have a new approach to occupational safety, which is part of the overall management of the company, and this project has touched him. In fact, this study has tried to guarantee the best working conditions and the presentation of the employees' rights, as well as to reduce the indirect costs resulting from occupational diseases and accidents at work. In other words, the internal audit carried out demonstrated compliance with the main requirements of OHSAS 18001 regarding environmental, health and occupational safety management
