Microorganisms can do physical and chemical transformations in the media during their growth in an organic-rich favorable environment. Adequate infiltration of organic-rich water into the porous media such as aquifers may cause intensive microbial activity and clog the pores by microorganisms. A sandbox laboratory experiment has been conducted for understanding impact assessment of bioclogging on the hydraulic properties of the porous media caused by aerobic and anaerobic microbial activities. A tank packed with medium-grained sand was saturated with growth medium prepared by dissolving source of organic matter, nitrate, sulfate, and iron in a tap water. To grow the complex microbial species in the tank, a 10 ml bacterial seed taken from
