Sachet drinking water produced and marketed by three different companies in Okada Community, Edo State Nigeria were examined and compared with the WHO drinking water quality standards. This was done to ascertain if they met the minimum required standard for human consumption. They were purchased and labeled E, F and I and were subjected to physicochemical and microbial tests. The parameters evaluated were TDS (Total dissolved solids), pH, Chloride, DO (Dissolved oxygen), Turbidity, Electrical conductivity (EC), Potassium, Calcium, Magnesium, Iron, Lead, Cadmium and Zinc. Their TDS ranged from 0.154 to 0.693 mg/L; pH ranged from 6.8 to 8.0; Cl- concentrations ranged from 5 to 10 mg/L; DO ranged from 5.4 to 6.5 mg/L; Turbidity ranged from 0.0 to 0.2 NTU and EC ranged from 0.330 to 0.451μS/cm. They were all within the limits stipulated by the considered standards. Their essential nutrient (K, Ca, Mg and Fe) contents were significantly less than the limits stipulated by the standards. Toxic heavy metals of Pb and Cd were below detectable limits. Total coliform count and SO42- concentrations were also zero. They had poor values of EC and very poor concentrations of essential nutrients. It was therefore recommended that there should be an improvement on the ratio of all the essential nutrients in the studied sachet water products to positively enhance the health of their users.
