Chemical and physical parameters as indicators of drinking water in sachet and bottled water in Ago-iwoye.pdf Download (2MB) |
Abstract
Sixteen (16) samples of sachet water with eight (8) nomenclatures were taken, four samples of bottled water were also taken from four different manufacturers, representing the most highly consumed drinking water in Ago-Iwoye and its environs. The samples were examined for physical and chemical parameters such as pH, conductivity, turbidity, Na, K, Fe, Zn, Mg, ammonia and nitrate. The analysis showed that the pH at 25oC ranged from 5.53 to 8.25 for sachet water while it ranged from 6.24 to 7.99 for bottled water. The conductivity () ranged from 15.8 to 220 for sachet water but ranged 20 to 200 for bottled water. Turbidity (FTU) range was 0 to 3 for sachet water while it ranged 1 to 3 for bottled water, total dissolved solid (mg/l) ranged from 10 to 110 and from 10 to 140, total hardness (mg/l) ranged between 28 to 53 and between 7 to 49 for the sachet and bottled water respectively. Bicarbonate (mg/l) ranged from 2 to 6 for sachet water and while it ranged from 12 to 84 for bottled water. Nitrate (mg/l) was found to range between <1.0 to 10.2 for sachet water and between 1.1 and 3.0 for bottled water. Sulphate (mg/l) ranged from 0 to 9.01 for sachet water and 0 to 4.9 for bottled water, phosphate (mg/l) was between <0.05 to 0.17 and 0.04 to 0.20 for sachet and bottled water respectively, Magnesium (mg/l) ranged from 0.57 to 15.55 and from 0.69 to 10.58 for sachet and bottled water respectively, Iron (mg/l) was found to range from 0.01 to 0.05 and 0.01 to 0.07 in sachet and bottled water respectively. Alkalinity (CACO3) (mg/l) ranged from 2.0 to 6.0 and from 12.0 and 84.0 in sachet and bottled water respectively. These results water showed that the sachet water samples were harder than the bottled water samples. The results were compared with WHO standard limit for drinking water and recommendations were made.
