| dc.description | Scarcity and quality of water are becoming major global concerns. The situation is worsened by the rapid urbanization and population growth in developing countries, including Libya, which increases competition for water used for domestic and agricultural purposes. Libya is one of the Northern African countries that have been experiencing water contaminations and shortages. The main purpose of this research was to determine the quality of water and the water supply shortages in the city of Al-Marj in Libya. Four research objectives were considered to achieve the main aim of the research, these are (1) to determine the quality status of water resource; (2) to examine the residential water quality; (3) to identify the public perception of water supply shortages and (4) to propose and validate a sustainable model for managing the water supply system. Standard techniques, such as Minitab (v. 16) and ArcGIS (v.10.1), were used to analyse the physicochemical and biological parameters of the groundwater samples and the residential underground water storage cisterns. An assessment of the calculation of groundwater quality was conducted on the basis of temperature, pH, turbidity, electrical conductivity, total dissolved solids, chloride, sulphate, bicarbonate, total hardness, calcium, potassium, magnesium, ammonia, ammoniacal nitrogen, nitrate, sodium, copper, iron, dissolved oxygen, biochemical oxygen demand, chemical oxygen demand, total suspended solids, Escherichia coli and total coliform bacteria. Therefore, the water samples of the groundwater wells were reported in high concentrations of (EC, DO, TDS, Cl-, Ca, NH3, NH3-N, BOD, COD, Escherichia coli, and total coliform bactria. On the other hand, the water samples of the water reservoirs were within the permissible limit of drinking water. The residential underground water storge cisterns in the study area display a higher concentration of few parameters consisting of (EC, DO, Cl-, HCO3–, Ca, BOD, TSS, Escherichia coli, and total coliform bactria compared with the permissible limits of drinking water. In addition, questionnaire survey was used to collect the data and Statistical Package Social Sciences (SPSS) Version 25.0 and SmartPLS were used to analyse the collected data. On the basis of the above results, routine water quality monitoring should be performed and additional water filtration plants should be installed by the local government to obtain safe drinking water. Based on the findings obtained from the conducted survey, the results indicate that the water supply management model fit indicates that the factors of this work are convenient and reasonably contribute to the performance of the water supply management model in the study area. The results showed that the environmental variable was the most important exogenous variable while the financial and technical variables were also effective in terms of importance and performance on water supply shortages. Recommendations have been drawn from this research. One of these recommendations is that the water shortage issues could be solved if the future government installs several desalination plants in Libya to supply each city with sufficient and clean water. Further, financial support is the backbone in solving this problem by interfering with the responsible authorities to establish the environmental monitoring of water quality in Libya in general and the city of Al-Marj in particular.,Ph.D | - |
