CHAPTER FOUR
4.0 RESULTS
4.1 Presentation and Statistical Analysis of Data.
This section presents the data analysis, testing of hypotheses and interpretation of results. All the data collected from the laboratory experiment are presented and interpreted. The analysis was carried out with the use of Statistic Package for Social Science (SPSS) application version 16 (U.S.A). The hypotheses were tested at 0.05 level of significance. The statistical tools used in analysing the data Analysis of Variance (ANOVA) and DUNCAN MULTIPLE TEST. This chapter presents the results and summary of findings under the following sub-headings:
- Testing of Hypotheses
- Summary of Findings
4.2 Testing of Hypotheses
The three hypotheses formulated for this study were tested one after another. Results obtained are presented on the tables below
• Hypothesis One: There is no significant variation in all the samples in study area of collection.

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 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---
