Unpolluted, polluted and remediated mudflat samples were collected in Bodo Creek, Rivers State, Nigeria to evaluate the ecological status of the area using impact analysis of sediment remediation by flushing technique on chemical properties and levels of some metals. Results showed that total organic carbon ranged from 21.5 – 23.0 % from the unpolluted to the remediated station, available nitrogen was 2.4 % and 2.5 % for the unpolluted and the polluted/remediated stations, total organic matter was 35 % and 40 % for unpolluted and polluted/remediated stations while available phosphorus ranged from 0.03 to 0.08 mg/kg for remediated to polluted/unpolluted stations. Sodium content ranged from 134 to 137 for unpolluted to polluted/remediated stations, potassium was 1779 mg/kg for unpolluted and 1370 mg/kg for the remediated station, calcium was 224 mg/kg for unpolluted and 296 mg/kg for the remediated station while Pb Cu were below detectable limits. It can be concluded that remediated station is safe ecosystem re-establishment.
