This study assessed the physicochemical and bacteriological characteristics of sachet and bottled
water brands on sale in Bolgatanga municipality, Ghana. Turbidity, colour, total dissolved solids, total
hardness, calcium ion, magnesium ion, total iron, chloride ion, nitrate ion, phosphate ion and sulphate ion of
all samples were within the WHO drinking-water guideline. About fifty percent of the water samples had
fluoride ion level ranging from 0.15-0.45 mg/L. These values are below the WHO recommended minimum
limit of 0.5 mg/L. Sachet water samples generally possessed good physicochemical characteristics. However,
three out of every four sachet water samples were contaminated by coliform bacteria ranging from 12-168
cfu/100 mL. Faecal coliform bacteria ranging from 2-63 cfu/100 mL were detected in more than 60% of the
sachet water brands. All the unbranded hand-filled hand-tied sachet water samples without exception were
contaminated by faecal coliform bacteria. This is contrary to the recommendation by WHO that faecal coliform
bacteria must not be detectable in a 100-mL sample of drinking water. Although two percent of the bottled
water samples had pH levels below the minimum level of 6.5 recommended by WHO, the samples generally
possessed good physicochemical and bacteriological characteristics. On the average, bottled water samples
were of good quality and the sachet water samples were of variable quality. This was probably due to the
problem of poor sanitation in Bolgatanga municipality and the fact that sachet water brands are not always
produced under scrutinised hygienic conditions.
