“…Smaller values of 38-96, 132, 78-80 mg/L were obtained in previous studies (Ghafari et al, 2010;Mohajeri et al, 2010;Aghamohammadi et al, 2007), confirming results of this study. Greater SS values of 1431 and 707 mg/L were obtained at semi-aerobic Pulau Burung Landfill Site (PBLS) and anaerobic Kulim landfill Site .…”

“…For KSLS, colour concentration ranged from 1120-3100 Pt Co, which were similar to previously published values (Tatsi et al, 2003). However, wider ranges of 5330-5760, 2430-8189, and 3790-4010 Pt Co were obtained by other studies Aziz et al, 2007;Mohajeri et al, 2010). The high concentration of colour in landfill leachate is due to the presence of high organic substances .…”

The general characteristics of Kuala Sepetang Landfill Site (KSLS) and Kulim Landfill Site (KLS) in the northern part of Malaysia were investigated. The average values of the parameters for leachate at KSLS and KLS, such as pH (8.05 and 7.59), EC (11.9 and 2.92 mS/cm), ORP (-33.02 and +17.8 On the other hand, parameters such as pH, copper, iron, manganese, nickel, and zinc remained within the allowable limits. The measured leachate would need an appropriate treatment strategy to reduce the pollutants to a satisfactory level prior to discharge into receiving system.

Hydrogen peroxide and ferrous sulfate were used to advanced treatment of landfill leachate effluent from biochemical tanks. Some influences on removing COD and chroma including the pH value of solution, the dosage of ferrous sulfate, the dosage of hydrogen peroxide and reaction time were investigated. The test results showed that for removal of COD and chroma the optimal pH was 3.0, the best ferrous sulfate and hydrogen peroxide dosage was 1500mg/L, 20mL/L respectively, and the optimal reaction time was 60min. Under optimal conditions, COD and chroma removal rate could reach 79.7% and 95.2% respectively.

“…Open landfills are the primary means of municipal solid waste (MSW) disposal in many countries worldwide including Nigeria because they offer low economic costs and have capacity to accumulate large amounts of solid waste compared to other methods such as incineration [1,2]. The absence of proper engineered landfills for disposal of wastes by the local and state governments has given rise to the proliferations of open dumps that are scattered in every nook and cranny of the country.…”

Leachate Characterization and Leachate Pollution Index from Landfill Dump Sites in Warri Metropolis, Nigeria

ABSTRACT. The paucity of standard engineered landfills in Nigeria has given rise to the proliferation of open waste dumpsites. The environment can be impacted by leachates from these dumpsites if not properly managed. This study assessed the characteristics of leachates from three open dumpsites in Warri Metropolis and its contamination potential using leachate pollution index (LPI). The dump sites had low pH with acidic level lower than the recommended limit. The calculated LPI values of the three sites ranges from 6.377 to 7.438. These values are low when compared to open dumpsites in other metropolitan areas of similar climatic conditions. The low value of LPI for leachate indicates relatively lower contaminant potential due to low concentrations of heavy metals, relatively young age of the landfill as well as low population and organic origin of the wastes. The calculated low LPI value does not in any way preclude the continuous monitoring of the dumpsites as the values recorded are just slightly below the threshold level. It is recommended that there should be an upgrade of all open dumpsites to a standard engineered landfill with a robust and effective monitoring put to curtail future release of deleterious materials from these dumpsites
