In this research, some groundwater specifications were evaluated for 5 areas of well water located in different areas in Zawiya city. These areas included (Warshfana, Al-Zawiya Al-Markaz, Dilah, Sayyida Zeinab, South Al-Zawiya), where some of the physical and chemical properties of well water samples were studied and the results were compared with the Libyan standard of 2015 and the specifications of the World Health Organization (WHO). This study showed that the well water samples that were studied are not suitable for human drink because they do not conform to international standards for drinking water, except for the water samples that were collected from the Warshafana area, where it was found that the concentration of total dissolved salts in the water samples collected from the Al-Zawiya Al-Markaz area, Sayyida Zeinab area and the Dilah area fall within a range greater than (1000 ppm). As for the samples from the Dilah region, the salinity level was very high as it is an area close to the sea, and therefore the water needs treatment and desalination operations before it can be used.
