Abstract
Assessment of <i>in-situ</i> abundance dynamics of enterobacteria and total heterotrophic aerobic bacteria in groundwater in the equatorial region of Central Africa
Highlights
Groundwater is present in the pores between soil or rock particles
Bacterial abundance dynamics in some cases was significantly correlated to some of these abiotic factors
The origin of some micro-organisms is uncertain, most underground bacteria derive from propagated infiltrated bacteria emanating from pollution of underground water by runoff (Mayer et al, 1997; Dzeda et al, 1998)
Summary
Groundwater is present in the pores between soil or rock particles. When all of the pores are filled up and the soils and rocks are saturated, an aquifer is formed. While surface waters are polluted, groundwater is protected by the soil that covers it, which acts as a filter for wastewater infiltration. The origin of bacteria in underground water is often debated. The origin of some micro-organisms is uncertain, most underground bacteria derive from propagated infiltrated bacteria emanating from pollution of underground water by runoff (Mayer et al, 1997; Dzeda et al, 1998)
