Analysis of the Impact of Waste Dumpsite on Soil Quality using Otamiri Hilltop Dumpsite in Owerri, Imo State of Nigeria as a Case Study
This study was carried out to determine the impact of waste dumpsite on soil quality using otamiri hilltop dumpsite in Owerri, Imo State of Nigeria as a case study. Soil samples were collected from the site using an auger and labelled appropriately and analyzed in the laboratory. The parameters tested are; Temperature, Color, Total Organic Matter Content, Moisture Content, PH, Lead, Mercury, Nickel, Cadmium, Chloride, Iron, Phosphorous and Nitrogen. Result shows that soil at the waste dumpsite is polluted by the waste. The soil in the study area were contaminated to various extent by heavy metals, having concentrations higher than permissible limits. The concentration of the heavy metals decreased as distance away from the dumpsite increased. Consequently, different solutions were proffered, both in short and long term to minimize and ameliorate the effect of dumpsite on quality of soil. They include; Strict enforcement of environmental rules and regulations, disposal of waste where its effect on man and the environment will be minimal or ground zero, treatment or detoxification of toxic waste before final disposal, among others.
