**4.4 Etiology, virulence, epidemiology, and pathogenicity of bacteria associated with borehole and sachet water**

From the studies reviewed, the organisms found in borehole water are wellknown food- and waterborne bacteria that are constantly monitored by regulatory authorities in many parts of the world. Outbreaks can occur in a community and cause fatalities and economic losses. Hence, a constant review of the growth conditions that enable the bacteria to proliferate, the features that enable survival in different environments, infection mode, and prevalence pattern of these bacteria is important to reduce outbreaks.
