Water is the first biological liquid. It facilitates the reactions of turning food into energy. It is also the means of transporting pollutants due to the large number of pollutants that reach it in different ways and cause many serious diseases that affect the health of living organisms, especially humans. This research was conducted due to the lack of sufficient studies on bottled drinking water that entered different new brands on the local market of the city of Benghazi, and this research aims to evaluate its quality. 10 samples of bottled drinking water in the market were collected randomly, sealed and sterile from the source of treatment and each sample carries a different brand and is (Enor, Safwa, Pure, Aquafina, Arwa, Reem, Aseel, Sultan, Al Ain, Arin). The sample collection period was January 2023 and the physiological, chemical and biology properties were revealed in the Precision Laboratory for Analysis. The results showed that the physical properties such as the total of dissolved salts and electrical conductivity are less than the upper limit of the Libyan standard specifications (126) mg/l (209) micromoses/ cm .the chemical properties of sodium (26.4) mg/l are less than the upper limit of the Libyan standard specifications and the international specifications WHO, as for the biology properties were two commercial samples (Al-Safwa, Arwa), it was found that they had a microbial growth for each colony unit formed in 1 ml, where the elite sample was 2 colonies and the Arwa sample was 8 colonized in 1 ml, while the rest of the study samples were within the limits of the Libyan standard specifications and the international specifications WHO.
