Abstract: Studies were carried out to determine the microbiological and heavy metal levels in sachet water samples stored at varied durations using standard biochemical and analytical procedures and, instrumentation. Cadmium had a mean range of 0.02 – 0.03 µg/g over the stored duration (0 -14 days ) of the samples, copper had a mean range of 0.63 -0.67 µg/g over the stored duration of the samples and zinc, had a mean range of 1.34 – 1.36 µg/g over the stored duration of the samples. Increased storage duration of the samples did not significantly alter the metal levels. The mean range of cell count for Staphylococcus aureus and Escherichia coli over the storage duration of the samples were 43 -21500 and 31 – 2410 Cfu/g respectively. Increase in the storage duration of the water samples significantly increased the number of viable cell counts of the isolated organisms.
