Abstract :
A significant portion of the global population relies on groundwater for drinking and domestic use, particularly in Nigeria, where urban and rural communities depend on it due to limited surface water access. This study assessed the perceived impact of canal water on the groundwater quality and residents in the Orile-Agege area of Lagos State, Nigeria. Physicochemical and microbiological properties were evaluated to determine suitability for domestic use using a mixed-methods approach. Sixteen samples from boreholes, wells, and canal water were analyzed, and 250 household respondents along the canal were surveyed. Data were summarized using descriptive statistics and compared against the World Health Organization (WHO) and National Standard for Drinking Water Quality (NSDWQ) guidelines. Correlation analysis explored relationships between groundwater quality parameters and canal water. Results showed the groundwater was acidic, hard, and contaminated with high nitrate levels, total coliforms, and E. coli, largely due to indiscriminate waste disposal, abattoir runoff, solid waste dumps, and agricultural activities near the canal. The study concluded that groundwater in the area is unsuitable for drinking or domestic use without treatment, emphasizing the need for public education and remediation efforts.
