Assessment Of Sachet Water Quality In Sokoto Metropolis

Abstract

Sachet water is among the alternative drinking water among the diverse users in households, industries, ministries, hospitals, schools, restaurants, markets and other places around Sokoto metropolis. Thus, this study sought to assess the presence and the level of physicochemical, heavy metals and biological parameters found in the sachet water produced and consumed in the study area. Therefore, the samples used in the study were purchased randomly from five sampling location and analyzed using standard method of analysis. The results of the study were being subjected to; analysis of variance (ANOVA), descriptive statistics and homogeneous turkey HSD analysis. The ANOVA results showed that all the physicochemical and heavy metals analysed varied significantly at 95% level of significance except chloride (0.081), alkalinity (0.087), total dissolved solids (0.204) and cadmium (1.000) respectively while the descriptive statistics and homogeneous turkey analysis showed that all the physicochemical and heavy metals analysed are within the WHO standard for drinking water except alkalinity with (365.068 mg/l), fluoride (3.245 mg/l) and nitrate (26.405 mg/l) and Fe (9.243 mg/l), Cd (0.02 mg/l) and As (7.503 mg/l) as highest concentration respectively. The biological results reveal that the total coliform bacterial load in the water samples is within the WHO standard of 0-10 MPN index of coliform in 100 cm³ of the water sample. The overall results of the study indicates that the sachet water produced and consumed in the study area are safe and suitable for consumption as more than 70% of the parameters analysed conform with WHO standard for drinking water.
