| Survey of Bottled Drinking Water Available in Manitoba, Canada Eva Pip Department of Biology, University of Winnipeg, Winnipeg, Manitoba, Canada Abstract
Forty domestic and imported brands of bottled water were purchased in Manitoba, Canada and examined for total dissolved solids (TDS) , chloride, sulfate, nitrate-nitrogen, cadmium, lead, copper, and radioactivity. The samples showed great variation in quality, and some exceeded the Canadian Water Quality Guidelines for drinking water for TDS, chloride, and lead. Carbonation, ozonation, and type of packaging were not associated with differences in metal levels, although carbonated samples tended to show higher TDS values. A number of deficiencies were found with respect to product labeling. Key words: bottled water, cadmium, chloride, copper, lead, nitrate, radioactivity, sulfate, total dissolved solids.
