Abstract

Majority of the population in Malete where research was carried out depend solely on wells as their major source of water supply because of the inexistence of treated pipeborne water. Due to increasing cases of water-borne diseases such as dysentery and cholera in some local Government areas in Kwara State recently, informed this bacteriological surveillance and monitoring of wells. Samples of well water were collected from seven different locations within Malete city in Nigeria and analyzed microbiologically using Membrane Filtration Technique and various isolated colony are tentatively identified based on their biochemical and physiological properties.The organisms were identified as Salmonella sp, Pseudomonas sp, Shigella sp, Escherichia coli, Enterobacter aerogenes, Klebsiella sp, vibrio sp,serattia sp and Proteus sp. The percentage occurrence of the organisms isolated from the well samples showed that Staphylococcus aureus was the most common (22.59%) followed by Escherichia coli (19.45%), and Pseudomonas species with 12.45% occurrence. Percentage occurrence of Salmonella and Shigella species were 8.95% and 12.45% respectively, while,  Serratia species was the least with 2.72% occurrence. Conclusively, proper well location and construction of good wells should be encouraged; control of human activities to prevent sewage from entering water body is the key to the avoiding bacterial contamination of drinking water. Household treatment such as boiling, use of chlorine should be encouraged before water from these wells is used for drinking and all other domestic purposes.
