Abstract

This research assessed the quality of water and by implication the functionality of the treatment plant units in Murtala Mohammed International Airport, Ikeja, Nigeria. Raw water samples were collected at eight different points from the plant to the end users for three consecutive months. Physico-chemical properties of collected samples were analysed using standard methods and compared with the World Health Organization (WHO) standard. The values of properties obtained for plant raw and treated water ranged from .19 - 7.4, 24.60 - 26.00oC, 3.79- 0.00 NTU, 33.30-16.70Hazen,0.17 -0.00mg/l and 36.7 -44.30 ppm, for pH, temperature, turbidity, hazencolour, iron content, total dissolved solid respectively. While the values obtained for total hardness, calcium hardness, magnesium hardness, residue chlorine, odour, electrical conductivity, nitrate, BOD and  Dissolved Oxygen, were 7.3 -5.7mg/l,3.7 -3.00 mg/l3.7-2.7mg/l,0.00 -0.00mg/l,46– 72µs/c, 0.59 - 0.56 mg/l,  3.23 - 4.17mg/l and 2.66 - 2.75 mg/l respectively. The values of parameters for the treated water were in all cases always better than those obtained for the raw water. All the physico-chemical properties obtained for the treatment line were within WHO standard except for raw water pH whose value was lower than the recommended WHO value. This observation showed that the treatment units improved the quality of the treated water and it is safe to use as potable water.
