Geoelectrical Surveys for Groundwater Exploration and Pollutionin Eastern Libya

Abstract
The thesis consists of three chapters: Chapter (I) Introduction and literature review; chapter (II) Materials and Methods and chapter (III) Results and dicusssion.
Chapter (I) presents details introduction aboutwater resources in Libya and groundwater of Al Jabal Al Akhdar. Also, presents physical, chemical and biological characteristics of groundwater. Additionally, chapter (I) deals with the geoelectrical resistivity survery and geolgoy of Libya.
Chapter (II) offers the detailed locations of wells in study area and used methods in analysis.Groundwater samples are collected from 10 wells atdifferent locations. The physico-chemical parameters such as pH, temperature, DO, EC TDS, calcium,magnesium, total hardness, sodium, potassium, nitrate, sulfate, iron, manganese and chloride are determinedusing standard methods and compared with WHO limits. The bacteriological analysis use the memberane filtre method (MF). For geoelectrical resistivity study, twenty seven vertical electrical sounding (VES’s), using Schlumberger array were carried out.
The obtained results in chapter (III) indicate that many of the estimated physico-chemical parameters of samples (1-7) are less than the permissible limits of WHO while, the results of the samples (8, 9 and 10) exceeds the permissible limits of WHO, reflecting that the wells arecontaminated and unfit for human consumption. Similar indicators are obtained by evaluation of the groundwater for irrigation uses.From bacteriolgoical study, for well numbers (8, 9 and 10) have faecal contamination of groundwater with coliform bacteria because the number of coliforms is highly comparative with theacceptable value whilenone of other wells were recorded any coliform number.
