This study is focused on the transport of Pseudomonas (P.) putida bacterial cellsin a 3-D model aquifer. The pilot-scale aquifer consisted of a rectangular glass tank withinternal dimensions: 120 cm length, 48 cm width, and 50 cm height, carefully packed withwell-characterized quartz sand. The P. putida decay was adequately represented by a firstordermodel. Transport experiments with a conservative tracer and P. putida were conductedto characterize the aquifer and to investigate the bacterial behavior during transport in watersaturated porous media. A 3-D, finite-difference numerical model for bacterial transport insaturated, homogeneous porous media was developed and was used to successfully fit theexperimental data. Furthermore, theoretical interaction energy calculations suggested thatthe extended-DLVO theory seems to predict bacteria attachment onto the aquifer sand betterthan the classical DLVO theory.
