Bacteriological Findings Of Reverse Osmosis Water From Karachi City

Water is one of the most abundant and essential element for all the living organisms. Safe drinking water is a need for human life. It is generally considered that bottled water is safe for usage by people. For long-distance travelers, it serves as the only source of reliable drinking water. But, several studies have reported that bottled water does not always meet the acceptability standards. In this study reverse osmosis plant water is used because it is able to do so much good in a way that it removes all dissolved salts, chemicals, impurities and microorganisms as well and is considered as safe, clean and pure for human consumption in any way. Therefore, it is important to analyze the quality of Reverse Osmosis water. There are various categories of bottled water and these are mineral water, spring water and purified waterThis study is based on the quantitative analyses of Gram negative bacteria in reverse osmosis purified water bottles because contaminated water poses great health risk, especially when it is used by infants, hospitalized patients and immuno-compromised ones. Gram negative causes some severe gastrointestinal diseases such as Cholera, Gastroenteritis, Typhoid fever, Salmonellosis, Shigellosis, Diarrhea, etc. For this purpose the samples of bottled reverse osmosis drinking water from different areas of Karachi were tested for the presence of Gram negative bacteria. The result of this study showed 14% of the samples, were free from Gram negatives and 86% samples were significantly positive for the presence of Gram negative. Thus water must undergo an effective treatment to reduce the bacterial count in order to prevent from infection.
