Establishing and maintaining public water services in fragile states is a significant development challenge. In anticipation of water infrastructure investments, we compared drinking water sources and quality between the dry season and the rainy season in Port Harcourt, Nigeria. In Port Harcourt, a city recovering from political and economic instability, residents have limited access to piped water, and they rely on a range of other private and public water sources.
We evaluated the effects of flooding, rain, and higher water table on water quality and classified sources according to their level of contamination. We investigated the influence of broader patterns of sanitation, drainage infrastructure, and land use on water quality from groundwater sources.
