database in the study area where none existed previously. Groundwater samples from bore-holes, hand-pump, and hand-dug wells of four densely populated towns in South- WesternNigeria were analyzed in respect to physicochemical factors, biological factors, and the metals Nickel (Ni), Lead (Pb), Cadmium (Cd), Zinc (Zn), Copper (Cu), and Iron (Fe) for six consecutive months from September 2012 to February 2013 to give mean values for each town and water source. Total aerobic plate, total coliform bacteria, and Escherichia coli (E. coli)were detected in most of thewater samples from the different towns and sources considered. Except for total suspended solids and total solids, the physicochemical parameters of all the samples were within permissible limits. The concentrations Pb, Ni, Cr, and Cd were above the minimum permissible limits. The presence of coliforms and E. coli in the groundwater samples indicates fecal contamination. The microorganisms isolated in this study include Enterobacteriaceae, Staphylococcus aureus, E. coli, Citrobacter, Klebsiella, Pseudomonas,Bacillus, and Micrococcus species. The analysis of variance of data obtained from this study shows that bore-hole water samples were safer for drinking that water samples from hand-pump, and hand dug wells across the communities
