Urban Definition and Drinking Water Safety
In Science for the Total Environment, Institute researchers reported the extent of disparities in water safety between urban and rural areas of Nigeria to be sensitive to different definition of urban extent. When comparing specific types of water source, findings were not conclusive as to whether water was safer in rural or urban areas. However, overall exposure to fecal contamination is more likely in rural areas as a result of much higher coverage of more frequently contaminated water source types.
