CHAPTER FIVE
5.0 DISCUSSION, CONCLUSION AND RECOMMENDATIONS
5.1 Discussion of Findings
The 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 pH, Okefomo and Irewolede were not different while Sawmill was different from both Okefomo and Irewolede. In terms of temperature, the three locations were significantly different from each other. Also, the turbidity of Okefomo was not different from that of Sawmill but statistically different from Irewolede. This study corroborates the work of G’amiz (2007) who found that pH and temperature of leachate show significant value in his study area.
This study also found that the presence of lead, mercury, selenium in the leachate from the study area does not show significant value. This means that the heavy metals in leachate within Ilorin can rarely do harm to our body. The locations examined in the study were not different in terms the heavy metal deposit. This result is possible where there is uniformity in rules and regulations guiding. This result is in line with Geismar (2014) who found heavy metals such as iron, mercury, zinc and cobalt to be common in leachate sites. On the final note, this study found the biomarkers of COD and BOD used for the study area show significant different and the result supported the earlier work of Milosevic (2012) who found biochemical and chemical oxygen are capable of infect diseases.
5.2 Conclusion
This study examined the physico-chemical component on dump leachate sample in Ilorin metropolis at the level of impact on the ambient environment. Therefore based on the findings from this study, it was concluded that;
1. The turbidity, pH and temperature of leachate in study area show significant variation from the study area.
2. The presence of heavy metals in the leachate from the study area shows no significant variation.
3. The biochemical oxygen demand and chemical oxygen demand used for the study area shows significant value.

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---
