Summary Introduction

In the rocks and soil of earths subsurface, there is water and this underground water is called as groundwater. The microbiology of associated shallow groundwater is quite identical to the microbiology of soils. Initially the subsurface microbiology focused on relatively shallow and accessible aquifer systems that disclose the diverse populations of Bacteria and Archaea. The microbes in the deep subsurface carry out processes that change the chemical makeup of a mineral, change the content of mineral in ground water and degrade pollutants.
