【 摘 要 】

This study characterizes the leachates quality of an active dumpsite in Warri,Delta State and also analyses its contamination or pollution potential. Leachate PollutionIndex (LPI) - a tool for quantifying pollution potential of leachates generated from dumpsites- has been used to quantify the leachates contamination potential of the dumpsite. The LPIvalues for the different sample locations L1, L2 and L3 were computed to be 5.69, 6.18 and5.89 respectively with a mean value of 5.80, while the control had a value of 4.82. These LPIvalues were also compared with the LPI standard (7.38) for treated leachates. Comparison ofthe mean LPI value (5.80) with the standard (7.38) indicated a relatively low contaminationpotential of the leachates. Moreover, it was observed that the concentration of the individualparameters of the leachates is quite variable. The organic strength (BOD5 divided by COD) ofthe dumpsite was less than 0.5, while the pH values indicated that all sample locations interms of age was mature, an indication of dumpsite stabilization. The study recommendscontinuous monitoring of leachates and upgrade to an engineered landfill to forestall possiblepollution problems in future.
