The study was carried out to assess the suitability of potable water used for domestic activities in ten selected locations at Isolu area of Odeda Local Government, Abeokuta. This is done to ascertain the qualities of the ground water being consumed in the locality. Several water quality parameters such as temperature, pH, electrical conductivity (EC), total dissolved solids (TDS), among others were measured using Atomic Absorption Spectrophotometer (AAS), Combined PH/EC/TDS meter and other standard procedures. The results of the physical parameters considered revealed the following ranges of values for minimum and maximum respectively; temperature (27.0 – 29.5oC), pH (4.65 - 5.06), conductivity (180 - 800 mg/L), and total dissolved solids (90 - 400 mg/L). In addition, the results of chemical properties examined yields the following minimum and maximum values; Potassium (27.00 - 30.00 mg/L), Sodium (8.00 - 20.00 mg/L), Nitrate (24.00 - 48.00 mg/L), Chloride (21.00 - 189.00 mg/L), Calcium (50.00 - 100.00 mg/L), Magnesium (20.00 - 54.00 mg/L) and Bicarbonate (60.00 - 244.00 mg/L), respectively. Potassium, sodium and chloride recorded concentrations below the WHO and NAFDAC standard of 200 and 100 mg/L, respectively. However calcium, magnesium and bicarbonate recorded concentrations higher than WHO and NAFDAC limits of 75, 20 and 100, respectively.
