Assessment of Water Quality in Slum Area Ibadan

Abstract

Adedayo Adeniran

The quantity of water is as important as the quality, since these affect the quantity and the quality of available water, water quality is used to express the suitability of water and sustainable to various uses or processes. It is affected by a wide range of natural and human influences, the most important of the natural influences is hydrological influence. The water qualities study was carried out in Ibadan using three landuse (urban, peri urban and rural) in slum areas of Ibadan were evaluated for these physicochemical parameters: temperature, total dissolved solid (TDS), pH, and dissolved oxygen (DO), from well, borehole, water from vendor or pipeborne, from 8 localities and 3 LGA in Ibadan. The results showed variations in the water quality parameters the slum areas. Water pH is lowest in Awotan and Apete of Ido LGA water source which makeup rural slums landuse. with water pH of 5.7 well and 5.8 borehole which is acidic, there is highest value of conc of Lead in these areas of (0.259 mg/l) compared to other landuse and locality, water is of best quality among water from vendors. Using the sig value of 0.05, that is no sig difference between the water quality in slum areas and WHO standards. Using Anova with physico-chemical parameters of water temperature, pH, dissolved oxygen, total dissolved solids, conc of zinc, and iron also having no significant. But a significant spatial variation of water quality of Lead concentration with the sig value of 0.033 and F value of 2.983. There is significant variation in different water source of water pH, total dissolved solid and dissolved oxygen. a sig value of 0.028, 0.031, and 0.000 respectively.
