Determination and Delineation of Groundwater pollution from leachate generated from dumpsite, Ijagun community Odogbolu southwestern Nigeria

The research examined the extent of pollution by leachate generated from Ijagun dumpsite, Odogbolu Area, Southwestern Nigeria, on the groundwater using electrical resistivity method. Four vertical electrical sounding measurements were taken around the dumpsite, Two on the dumpsite (VES 1/ VES 2), and the other two (VES 3 /VES 4) around the dumpsite (serving as control) using schlumberger array technique. The result obtained interpreted both quantitatively and qualitatively, iterated with WINRESIST software. From the computer output, three curve types were obtained from the field survey (A, H, KHA). There is indication of the presence of the contamination in the VES 1 (layer 2) and VES 2 (layer 2) due to their low resistivity values while there are yet no pollution in VES 3/ VES 4 due to their high resistivity values compare to that of VES 1 and VES 2. The stratigraphy at the dumpsite consisting of Sand, Dry sand and Sandstone which shows that the dumpsite is situated on aquiferous materials that is highly porous and permeable and may aid the free flow of leachate into the groundwater. Therefore, there is need for drinking water quality assessment to determine the suitability of the groundwater for human and industrial consumption

Assessment of Perceived Health and Environmental Problems of Household Energy Consumption among Ilese Ijebu Residents Southwestern Nigeria

The study was carried out among Ilese-Ijebu residents southwestern Nigeria, to assess their perceived health and environmental problems associated with different sources of household energy use for cooking, then their perception and acceptability of adopting other alternative source of energy (biogas). A focused group discussion and self-structured questionnaire administration methodologies were adopted to elicit information on their current energy sources and adoption for alternative energy source (biogas). The researchers randomly selected twenty five (25) households to include the total sample size of one hundred (100) and organized an interactive session on the subject matter, during which three prepared forms were given out to the participants to filled their demographics characteristics, sources of energy for household cooking with associated health and environmental problems and perception and acceptability of biogas, descriptive statistics and likert scale technique were used to analyze the results obtained. The results of the analysis showed that, the respondents do make use of more than one source of energy for cooking, kerosene stoves (95), firewood (63), charcoal stove(32), while lesser people made use of liquefied gas (12) and electricity (5). Average numbers of respondents 50-60 are aware of associated health and environmental problems with firewood and charcoal, but not ready to use electricity and liquefied gas because of bills and fire hazards when the energy sources is  not properly handled. However, the likert scale results of the positive score of 227 and the negative score of 598 on the acceptability of use of biogas for domestic cooking indicating that, presently, the residents are not ready to adopt the biogas as the alternative energy. Therefore, there is need to organize massive awareness campaign, health education talks among the residents on the effect of air pollution associated with household energy sources and consumption, health and financial benefits of adopting other alternative clean energy source
