Physico-chemical Investigation On Dumpsite Leachate
[A CASE STUDY OF ILORIN METROPOLIS] -

Currently, the most widely used method of Leachate treatment is re-infusion and release into a municipal water treatment facility (Christensen, 1994). This method is effective in that it increases the rate of leachate deterioration and creates landfill gas (Christensen, 1994). This decreases the overall volume of leachate, but unfortunately also condenses the contaminants inside the fluid (Lopez, 2004).
Leachate is also released into to local watercourses, but due to restrictions placed on the chemical composition of the leachate released this way, it must be pre-treated first (Li, 1999). Leachate can be dealt with on-site or transported to specialist treatment facilities (Christensen, 1994). Treatment normally involves using activated sludge to break up the organic substances, but in many cases is still not environmentally safe at this stage so is transported to neighbourhood sewers (Christensen, 1994).
The selection of the best treatment methods is controlled by several factors such as:-
• Leachate characteristics – organic and inorganic contents.
• Hazardous nature – concentration of organic, inorganic and toxic metals.
• Degree of treatment – leachate characteristics, legal requirements and discharge alternatives.
• Treat–ability studies, available experimental data and applicable technology ( Heyer & Stegmann, 2000).
• Cost - availability of funds

CHAPTER ONE - [ Total Page(s): 3 ]6 Significance of the study This study is important because it serves as a medium through which numerous problems associated with the waste dumpsite can be address. This is also necessary because it is hoped that through its outcome, the magnitude of the environmental contamination in the study area will be highlighted. The outcome of the study may also give the government to appreciate waste management strategies and controls measures over indiscriminate dumping of waste. Furtherm ... Continue reading---

CHAPTER FOUR - [ Total Page(s): 4 ]Superscripts a, b and c show that the values are significantly different while all the values bearing the same letter shows there no significant difference. The pH for Okefomo was 7.63 ± 0.16, Sawmill was 8.71 ± 0.15 and Irewolede was 7.79 ± 0.33 respectively. When pH of the three locations were compared, Okefomo and Irewolede were not significantly different while Sawmill was found to be different from both Okefomo and Irewolede (p ... Continue reading---
CHAPTER FIVE - [ Total Page(s): 2 ]CHAPTER FIVE5.0 DISCUSSION, CONCLUSION AND RECOMMENDATIONS5.1 Discussion of FindingsThe thrust of the study was on the physico-chemical component on dump leachate sample in Ilorin metropolis at the level of impact on the ambient environment. The findings revealed that turbidity, pH and temperature of leachate in study area show significant value. This means that the values of pH and temperature of leachate in study area are such that can exalt negative influence on people. With respect to ... Continue reading---
