Physicochemical and bacteriological quality and safety of packaged drinking water in Ouagadougou, Burkina Faso
Urban packaged water samples of Ouagadougou were studied in order to assess their bacteriological and chemical characteristics and suitability for potable purposes. The study also investigated the sanitation of the companies producing packaged water. Packaged water from 17 different brands was purchased and analyzed for physicochemical (turbidity, pH, EC, total hardness, NH4+, NO3-, HCO3-, SO42-, and Cl−) and bacteriological (total coliforms, Escherichia coli, Pseudomonas aeruginosa, Enterococcus, and sulphite-reducing anaerobic bacteria) parameters. The production sites investigation included: (1) distance between latrines and water sources superior to 15 m, (2) hygiene of handling personnel, (3) training of handling personnel on good hygiene practice and manufacturing, (4) hygiene of premises, and (5) hygiene of toilets. All the samples met the national guidelines for the physicochemical parameters investigated. Enterococcus, sulphite-reducing anaerobic bacteria spores, and E. coli were not found. Total coliforms were found in 8 (47.1%) in February, 9 (52.9%) in March, 2 (11.7%) in April, and 5 (29.4%) in May, while 7 (41.2%) brands were always in compliance with the guidelines. Some packaged waters were contaminated with total coliforms or P. aeruginosa above acceptable limits for human consumption. Regarding bacteriological contamination, it is necessary to reinforce water treatment systems in certain packaged water companies. HIGHLIGHTS Physicochemical and bacteriological parameters were evaluated using standard methods to have an overview of packaged water in Ouagadougou.; Packaged water companies have implemented various treatment techniques.; The use of reliable treatment systems is of crucial importance in view of the results obtained.;
