Abstract: The study was carried out on comparative analysis of the physico-chemical parameters and heavy metals concentrations on three water samples each from borehole and sachet water selected randomly from Igboora in Ibarapa central local government area of Oyo State. The physico-chemical parameters were measured using standard method while the heavy metal concentrations were examined using Atomic Absorption Spectrophotometer (AAS). The result of the physico-chemical parameters showed that turbidity ranged between (0.000) Ntu across samples examined, NO3 - ranges between (5.04-19.99 mg L–1) with highest sample in sample A (Surulere borehole water), PO4 - ranged between (0.74-2.65 mg L–1), pH (6.70-6.94 mg L–1), EC ranged (199.20-374.00) μs cm–1 with the highest value recorded in sample C, respectively. Heavy metals were detected below limits in borehole water samples. However, sachet water samples recorded 9.875 Ntu for turbidity, EC ranged between (149.900-162.000) μs cm–1, higher pH values were also recorded for sachet water which is between (7.490-7.620 mg L–1). Similarly, heavy metal concentrations were detected below limit for both borehole and sachet water except that manganese and zinc revealed values in some samples, respectively. It was noted that all physico-chemical parameters examined for borehole and sachet water were within WHO threshold limits except for values of NO3 -, COD and BOD. The water is safe for drinking if the appropriate measure is taken to regulate high parameters.
