ABSTRACT

The isolation and identification of bacteria from waste dump soil was conducted by analysing samples of soil at different dumpsites along roads leading to different colleges and places within Michael Okpara University of Agriculture, Umudike. Bacterial analyses of soil samples using serial dilutions of the soil samples was carried out. Biochemical test was carried out to identify the particular types of bacteria isolated. The mean total bacteria count ranged from 3.4 x 105 (CFU)/g to 9.7 x 105(CFU)/g of soil. The bacteria isolated were Escherichia coli, Staphylococcus sp., Proteus sp., Salmonella sp., Shigellasp., Pseudomonas sp. and Klebsiellasp. The mean pH values ranged from 7.08 to 8.70, the mean moisture contents ranged from 8.2% to 17.5%, while the mean temperature values ranged 280C to 300C. The study revealed 7 genera of bacteria, 5 genera of which portend fecal contamination. It was inferred from this study that bacterial load poses a great risk not only to waste scavengers but also to the society thereby constituting some public health hazards. Aerobic bacteria are usually more likely contaminants of soil than anaerobic bacteria, this is especially considering the fact that the environment is aerobic. The study recommended that regular safe quality assessment of dump soil is essential considering the possible socio-economic and health implications of contaminated dumpsites.
