Physicochemical Characteristics and Evaluation of Waste Landfill in Rumuagholu, Rivers State, Nigeria

This study was conducted to evaluate the physico-chemical characteristics and pollution aspect of wastes in Rumuagholu landfill and their health effects in two stations at Rumuagholu, Rivers State, Nigeria. Parameters including temperature, pH, electrical conductivity, salinity, nitrogen, potassium and phosphorus were examined following standard methods. Additionally, heavy metals (Cd, Ni, Zn, Cu, Pb, Cr, Mg, Al and Fe) were analyzed using atomic absorption spectroscopy (AAS). The findings indicated elevated levels of salinity and nitrogen surpassing permissible limits, and a slightly acidic pH in both stations. The statistical analysis shows the values were not significantly different (P<0.05). Heavy metal analysis identified Cd, Pb, and Cr exceeding permissible limits in both stations, suggesting a significant presence in the landfill. Continuous monitoring and potential upgrades to an engineered process are crucial to decrease the pollution problems in the future.
