Evaluation Of The Physicochemical And Microbial Quality Of Three Bottled Water Samples Sold At Michael Okpara University Of Agriculture Umudike.
ABSTRACT
In this study, different bottled water brands in Michael Okpara University of Agriculture were compared and analysed. The standard water testing methods were used to access the physicochemical and microbiological quality of these samples (Mr V Table Water, CWAY Table Water, Eva Table Water and Pax Table Water). The four water samples do not conform to the World Health Organization acceptable standards of zero bacteria for drinking water as they contain significant amount of bacteria ranging from 3.5×10¹CFU/ml to 4.45×101CFU/ml. However, Eva water had the lowest Total Bacteria Count of 3.5 ×101. The four samples showed zero presence of Fungal and Coliform micro-organisms which are within the WHO standard for zero condition for portable water. The physicochemical parameters such as; Electrical Conductivity (EC), pH, Total Dissolved Solid (TDS), Hardness, Iron (Fe), Chloride (Cl), Nitrate (N), Fluoride (F) and Copper (Cu) were all below WHO acceptable limitsfor all water samples tested except for the alkalinitythat ranged from 140.35 mg/l to 145.23 mg/l and phosphorous (0.79-0.94) which were found to be above the permissible limit of 50mg/l and zero respectively as recommended by the World Health Organization. Public awareness should also be created that bottled water may still be impure, despite appearing attractive and convenient.
