Micro biological Assessment of Borehole Water in Libala South, Lusaka District, Zambia

ABSTRACT

Background: The rapid population growth coupled with massive infrastructure development in the city of Lusaka has resulted into the extensive use of contaminated ground water leading to adverse health effects on human health.

Aim: This study was conducted to assess the levels of microbial contamination in boreholes water in Libala South of Lusaka Distric t.

Methods: A cross - sectional study was conducted in Libala South Township involving 64 households. Households were randomly sampled using stratified systematic method. Borehole water samples were collected, and analyzed for microbial contamination at the Food and Drugs Laboratory, Lusaka. The samples w ere tested for the presence of coliforms and Escherichia coli bacteria by using Colitag™ testing kit and the confirmation was done using multiple tube fermentation method

Results: The study revealed that 31% and 48.5% of the boreholes were contaminated with Escherichia coli and coliforms, respectively.

Conclusion: Almost half of the borehole water in Libala South is contaminated with harmful bacteria and poses a public health risk to the residents who opt to use it for drinking and cleaning foods .

Key words: Borehole water, Microbial contamination, Total coliforms, Escherichia coli , Libala South Township, Lusaka
