Abstract
With the recent increase in the consumption of sachet and bottled water in major cities and towns in Nigeria, there are several infections associated with food and water and there is a growing concern for the safety and quality of drinking water. Assessment of physicochemical parameters and heavy metals were carried out in potable water of Ilaro town. Ten samples from five popular sachet water factories were collected directly from the water factories (two per industry). The samples were examined physically and chemically using AOAC standard methods and instrumentation. The values of pH, electrical conductivity (EC), total dissolved solid (TDS) and alkalinity (HCO3) are found to range from (6.14 – 6.82), (81.90 – 169.8), (36.86 – 74.01) and (12.50 – 60.55) respectively. The pH concentrations in two of the samples were found to be lower than World Health Organization (WHO) standard of 6.5 in drinking water. Concentrations of heavy metals (Lead , Manganese, Nickel and cadmium) were determined using atomic absorption spectrophotometer. Some of them were not detected by the instrument, while manganese was found to be above the stipulated limits in some samples. It was concluded that though the value of the pH and manganese concentration in some samples did not fall within the WHO limits, they do not pose any serious health risk to consumers. Generally, the result obtained in this study indicated that the potable water produced and sold in Ilaro were of good quality and hygienic for consumption.
