This present study evaluates the sediment characteristics of Ethiope River, Niger Delta, Nigeria. The investigation was carried out between January 2016 and December 2017 to ascertain the impact of anthropogenic activities on Ethiope River. Five locations were selected from Umuaja to Eku for this study. Sediment samples were analysed using standard methods. Different biometric indices were used. The Enrichment factor revealed high content for nickel, lead, and vanadium. The Geoaccumulation index (Igeo) showed a moderately to heavily polluted sediments with nickel, chromium, cadmium and vanadium. The results from pollution load index (PLI) values ranged from 1.44 to 3.10 for (2016) and varied from between 1.38 to 5.10 for (2017) indicated contaminated sediments. The
potential ecological risk revealed high cadmium concentration and a very strong risk level at locations 3 and 4 of the river. Concentrations of Heavy metals obtained will act as a mitigation plan for monitoring anthropogenic activities along the stretch of Ethiope River
