A structured questionnaire was administered to 1,398 households in 16 settlements using a random sampling method. Descriptive statistics and SDI were employed to analyze the data while ArcMap was used to map the patterns of SDI. The results show that households live in poor dwelling conditions with limited access to WaSH facilities. The SDI indicates that 18.7% of the slums are highly deprived. Based on WaSH and dwelling and physical environment (DPE) components, 18.75 and 31.25% of the slums are highly deprived. Water, sanitation, and hygiene indicators show that 37.5, 12.5, and 56.25% of the slums are highly deprived respectively. About 50, 37.5, 43.75, and 31.25% of the slum are highly deprived based on dwelling, waste disposal, waste pile, and stagnant water respectively. The study c...

However, existing studies have largely glossed over individual community deprivations and allowed spatial heterogeneity to be masked by gross generalization. Using geospatial information systems (GIS) and slum deprivation index (SDI) this study described the residential and water deprivations of 15 selected slum communities in Lagos Nigeria. Based on residential conditions we found that majority of the residents lived in one-room apartments and in neighbourhoods with about 20 persons per dwelling. The residents were without access to improved drinking water, and lived in dwellings surrounded by solid waste piles. The slum deprivation index (SDI) indicated that residents experienced critical residential and environmental deprivation and water, sanitation and...

Samples were collected and analyzed following standard methods for the examination of water quality (APHA, 2005). Parameters studied include pH, Electrical Conductivity (EC), Total Dissolved Solids (TDS), Turbidity, Total Hardness, Nitrate, Chloride, Sulphate, Calcium and Coliforms. Physicochemical parameters such as EC, TDS, nitrate, chloride and sulphate were within the limits set by the WHO. However, the water quality observed at Majidun shows that the concentration of calcium, total hardness and TDS were above acceptable limits. Also, e-coli were detected in samples from Majidun along with Gberigbe and Imota.

Water Quality Index (WQI) is one of the most effective tools to communicate information on the quality of water to concerned citizens and policy makers. In this study, 18 locations were selected within the urban catchment using random sampling technique. The water samples were collected and analyzed for physico-chemical parameters including pH, Total Hardness, Calcium, Magnesium, Chloride, Nitrate, Sulphate, Total Dissolved Solids and Iron using standard procedure. The sampling locations were determined with GPS and interpolated on digitized topographical map of the study area. The 9 parameters were used for calculating Water Quality Index within the study area. The result show that, the groundwater quality ranges between 0.86 and 1,228.0mg/L. Total Dissolve Solid has the highest m...
