Various anthropogenic activities can influence groundwater quality; therefore, regular water quality monitoring is important to safeguard public health. The study examines the physicochemical and heavy concentration of selected borehole water along pipeline routes in parts of Obio/Akpor Local Government Area, Rivers State, Nigeria. Water samples (15) were sourced from communities (Rumuoke, Rumukania and Egbelu) where decommissioned pipelined pass through and analysed for physicochemical and heavy concentration following the standard methods of the American Public Health Organisation (APHA) and the American Society for Testing and Materials (ASTM). The findings revealed that the pH mean concentration was 5.34 across the study area, and all concentrations reported are within the WHO and NSDWQ allowable limits. The mean concentration of electrical conductivity (107.51 µS/cm), TDS (69.73 mg/l), 〖NO〗_3^- (0.02 mg/l) and 〖Cl〗^- (4.52 mg/l) reported are within the WHO and NSDWQ allowable limits. All the reported parameters tested are within the allowable limit standard of WHO; however, various human-related activities that can influence water quality must be closely monitored, and adherence to various environmental guidelines against water pollution is essential.
