3.2 Leachate Sampling
The city of Ilorin falls into Southwestern and North central on geological and political classifications respectively. It is the capital town of Kwara State, Nigeria, with a population estimate of 2,185,494 people (NPC, 2007) which is responsible for the generation of waste often deposited in open spaces, river banks, road side etc. thereby degrading the quality of the environment, Ilorin comprises of three Local Government Areas namely: Ilorin West, Ilorin South and Ilorin East which is the study area. The study area (Okefomo and its environment) is located within latitude 80 29.400’’ N and 80 30.500’’ N and longitude 40 33.00’’E and 40 34.500’’E in Ilorin West.
The diagram below shows the location of one of the area in which the leachate sample is been collected. The area serve as the main area where people dump there refuse because water flow through the place while the dumpsite in Okefomo has an approximated area extent of 2.5 x102m2.

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 TWO - [ Total Page(s): 11 ]Usually, the main reason for the presence of heavy metals in landfill leachate is the lack of awareness among the people. A lot of hazardous waste such as clinical bandages, batteries and medicine are found in the refuse sent to landfills (Hamidi et al., 2003). Also, heavy metals such as iron, manganese, zinc, chromium, lead, copper and cadmium are present in high concentrations in the landfill leachate. These minerals can cause pollution to groundwater, surface water and reservoirs (Aziz et al. ... 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---
