The study carried out ecological evaluation and modeling of metallic contamination levels in soils from the reclaimed section of River Otamiri wetland in Southeastern Nigeria. The study was aimed at ecological evaluation and modeling of contaminant levels of the reclaimed wetland soils. This was in order to determine the extent of metallic contamination of the wetland. The metallic contamination level was established with the help of Energy dispersive X-ray fluorescence spectroscopy (EDXFS). Pollution models were used to carry out ecological evaluation of the metallic contamination levels. The result revealed that the mean values of the metals were in the order; 0.29 < 0.59 < 0.88 < 16.74 < 50.44 < 129.48 < 259.34 < 341.22 < 518.70 < 563.14 < 39888.63 mg/kg for Cd 1 for all the samples, which is a serious ecological concern for the reclaimed wetland as it implies that the area is polluted. Geo-accumulation index analysis ranged from no accumulation to moderate accumulation. Result of ecological risk index analysis point to the fact that the risk posed by the metals ranged from low to high risk. The radar plot, principal component analysis (PCA) and hierarchical component analysis (HCA) suggested that related sources were responsible for the metallic contamination of the wetland. Hence, there is need to discontinue further reclamation of the area for human habitation due to elevated metallic contamination of the area.
