Abstract
Wastewater management in Lagos slums is a critical public health issue due to inadequate sanitation infrastructure. A longitudinal study using qualitative and quantitative data collection methods, including interviews, surveys, and microbiological testing. Microbial contamination levels decreased by an average of 30% over two years in treated wastewater compared to untreated. Wastewater treatment systems have shown promising results in reducing microbial pathogens, though further research is needed for sustainable implementation. Continue monitoring and improve infrastructure quality, considering community engagement for effective long-term use.
