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 years, communities have used the springs in their vicinity. However, the government does not seem to take care of the springs' quality or their yield. Furthermore, the rapid urbanization brings in 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 southwest Nigeria. The results indicate that of the 16 springs, 13 served primarily as sources of drinking water. The yields ranged from 3320 to 8308.8 l for an 8 h period. Physico-chemical quality was in conformity with the recommended standards. The pH values varied between 6.25 – 6.89 and 6.34 – 6.94 and temperature values varied between 26.5 – 26.6 and 26.43 – 26.6 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 that the country is trying to meet.
