The demand for drinking water is increasing daily due to the rising world population, alongside the leakage of water, overuse of groundwater, and occurrence of several pollution issues that led to reducing the quality of groundwater. Consequently, in most countries purifying water technologies have been used to obtain drinkable water. Nationally, Libyans use the purified water extensively in their daily needs. Accordingly, to ensure that our citizen utilize harmless water, the quality of the used water and the efficiency of purification units was assessed by analyzing several physical and chemical characteristics of purified water and raw water supplied to the purification units from some local wells and man-made river (MMR) using recommended standard methods. The study results showed that the quality of purified water is excellent, and the purification process reduced the pH, electro conductivity and the concentration of studied chemical properties significantly to values less than the optimum levels (OL) suggested by the World Health Organization (WHO) and Libyan standards (LS) for drinking water. As a conclusion, the studied purified water may use in the daily needs of human with continuously analytical monitoring.
