Assessment of surface groundwater quality in the area affected by rising groundwater levels in Zliten, Libya
الملخص
The study area is witnessing a steady increase in population due to its geographical location, availability of agricultural land, and proximity to basic services. However, due to the lack of infrastructure, such as sewage networks and low terrain, it is suffering from a rise in groundwater levels, which has negatively affected the quality of water suitable for drinking and domestic use. This study aimed to evaluate the physical and chemical quality of water and compare it with Libyan and international standard specifications, and to verify that the study samples are free of ammonia as an indicator of microbial groundwater contamination. Eleven water samples were collected from wells representing the affected area. The results of the sample analysis revealed that they had a high content of total dissolved salts. The study also showed that the concentration of ammonia was less than the permissible limit in all wells except for one well. In general, the analysis results showed that most of the samples were not suitable for drinking. Through statistical analysis of the samples, it was found that there were no significant differences for all elements between January and November 2024 AD
