Springs as supplementary potable water supplies for inner city populations: a study from Ibadan, Nigeria
Potable water is a major problem in urban centres in Nigeria. For decades, communities have been in the habit of utilizing springs in their vicinity as a source of potable water. However, the Government does not concern itself with the water quality or yield of springs, particularly in light of rapid urbanization which is associated with a variety of pollutants through seepage and underground infiltration. A study was conducted to assess the quality of the various spring waters used by the inner city populations in Ibadan, a heavily populated capital of Oyo State in south west Nigeria. The results indicate that of the sixteen springs, thirteen served primarily as sources of drinking water. The yields ranged from 3320 to 8308.8 litres for an eight hour period. Physico-chemical quality was conformed with the recommended standards. The pH values varied between 6.25 to 6.89 and 6.34 to 6.94 and temperature values varied between 26.5 to 26.6°C and 26.43 to 26.6°C for the rainy and dry seasons, respectively. The Total Dissolved Solids varied according to the soil type and terrain. The bacteriological quality needs to be corrected through simple treatment such as filtration and disinfection. If these water sources are tapped effectively, pressures on conventional water supplies will be reduced particularly in view of the current Millennium Development Goals which the country is trying to meet.
