To achieve the goals of the study, many chemical and biological analyses were performed on 23 samples of groundwater. The analysis included electric conductivity EC, Total dissolved solids, TDS, pH, some cations and anions Mg2+, Ca2+ , K + , Na+ , Cl- , NO3 - , SO4 - and some heavily and micro elements like Hg, pb, Cu. Total coliform and fecal coliform bacteria were screened. The sodium adsorption ratio (SAR) adjusted sodium carbonate were collected as well. The results revealed that according to the Libyan and WHO standard the majority of the groundwater samples were influenced by wastewater, seawater intrusion.
