[Physicochemical composition of bottled drinking water marketed in Ouagadougou (Burkina Faso)].
The bottled drinking water marketed in urban areas includes natural mineral water, spring water, and treated drinking water. Their physicochemical qualities depend on the type and quantity of their components and define their safe use. Bottled water is widely consumed in Ouagadougou (Burkina Faso), and many brand names exist. Although many publications have examined the microbiological qualities of such water, no study has examined the physicochemical quality of water from Burkina Faso. This study, conducted from March 2005 through January 2006, aimed to assess the physicochemical composition of drinking water sold in Ouagadougou to facilitate better choices and use by consumers. Results showed that all the water analyzed in Ouagadougou is soft (TH < 50 ppm) or moderately soft (50 < TH < 200 ppm) and weakly mineralized (total dissolved solid content < 500 mg/L, sulfates [SO(2-)(4)] < 200 mg/L, [Ca(++)] < 150 mg/L, [Mg(2+)] < 50 mg/L, and [HCO(3)-] < 600 mg/l). Some imported water, however, is hard and highly mineralized. French standards do not set limit values for the natural mineral water parameters described above, and much of the water sold in Ouagadougou was natural mineral water. The spring water met potability standards, except for the Montagne d'Arrée brand, which had a pH value of 5.8, below the WHO standards of 6.5 < pH 8.5.
