This study investigates the repercussions of oil industry operations on environmental quality in the Niger Delta, with a specific focus on atmospheric soot contamination. By conducting chemophysical and metallic characterization of surface water (river) and precipitation (rain) in Oyigbo, Rivers State, Nigeria, the research evaluates various chemical and physical parameters, like pH, electrical conductivity (EC), total suspended solids (TSS), turbidity, as well as concentrations of heavy metals like lead (Pb), copper (Cu), cadmium (Cd), and zinc (Zn). The findings uncover a slightly acidic to neutral pH in water samples. The elevated EC in the Imo River, while meeting WHO standards, highlights the delicate balance between industrial development and environmental health. Turbidity values, meeting WHO standards but exceeding limits in some rainwater samples, prompt scrutiny of Journal of Global Ecology and Environment Volume 20, Issue 1, Page 28-57, 2024; Article no.JOGEE.11918 ISSN: 2454-2644 Chemophysical and Metallic Characterization of Surface Water and Precipitation for Environmental Quality Assessment in Oyigbo L.G.A., Rivers State, Nigeria Nurudeen Onomhoale Ahmed a* , Godwin J.
