Abstract

This study Was Carried at the area of Tajura. It covers three places, AL Hamedia, Sidi Khalifa and Industrial Compounded (AL-mojamma Assinay). The Study aimed to investigate the influence of some contaminations which may be produced from wastewater treatment plants in the study area, and from the landfill of the industrial compound. The quality of the ground water of the sites were determined according to the Libyan standard of drinking water No 82 for the year of 2013 and according to the world health organization standard, 1989. 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. The results also showed that most of the wells located in Al Hamedia area were contaminated with coliform bacteria. However, the ground water sample of well No 3 and 7 were under the allowable limits according to the Libyan standard for drinking water 2013.
