STUDY OF THE PHYSICAL, CHEMICAL AND BIOLOGICAL PROPERTIES TO EVALUATE THE QUALITY OF SOME BOTTLED WATER SAMPLES IN DIWANIYAH GOVERNORATE / IRAQ
The main objective of the current study is to ensure obtaining pure water by determining the physical and chemical properties such as (TH, EC, pH, Ca, Mg, NO2, PO4, SO4, NO3) in addition to determining the biological properties Total bacteria account (T.P.C). For 14 samples of bottled water circulating in the markets of the city of Diwaniyah (Aafiat, Akram, Nawar, Yaqout, Wahat karbala', Rona, Life, Lulu’a, Login. Dinar, Saha, Sawa, Aquafina, Almas), the obtained results were compared With the standard specifications specified by the World Health Organization and the Iraqi Ministry of Health and Environment, where it was found from the chemical analyzes of the chemical elements and physical properties of all samples that they were within the standards and specifications of the World Health Organization and the Iraqi Ministry of Health and Environment, while biological analyzes showed that there was bacterial contamination of some samples Water that exceeded the permissible limits, as it showed T.P.C values (564, 252, 170) compared to the permissible limits of 100 (cells / 1 ml).
