An assessment of the quality of drinking water in Benghazi City, Libya(Determination of physical parameters)

The major sources of water supply of Benghazi city is the River Project which is represented in Talhia reservoir where water flows through pipes in the network of water distribution from Talhia reservoir to different positions in the city. In this study we divided the study area (The network of water distribution) into three areas A, B and C according to the distance away from Talhia reservoir. Drinking water samples were collected from twenty six positions of Benghazi city during spring and summer seasons-2009. These samples were subjected to systematic analysis using standard methods and procedures. The obtained results for water of the network were compared with Libyan and WHO drinking water standards. Physical parameters of the three areas A, B and C were compared for water of the network between spring and summer seasons. The physical parameters that were determined in this study are pH, temperature, electric conductivity (EC), total dissolved solids (TDS) and turbidity. All physical parameters of the network water samples agree well with Libyan and World Health Organization (WHO) drinking water standards, however we found that there are differences in the majority of physical parameters of water between the studied three areas A, B and C, there are differences between results of spring and summer seasons. There are small values of turbidity in some positions at summer season these values were less than that of Libyan guide line values (5NTU).
