The impact of bacteria-solid and bacteria-bacteria interactions on the transport of Klebsiella oxytoca, Burkholderia cepacia G4PR1, and Pseudomonas sp. #5 was investigated in saturated sand column experiments (L = 114 mm; circle divide = 33 mm) under constant water velocities (similar to 5 cm . h(-1)). Bacterial strains were injected into the columns as pulses either individually, simultaneously, or successively. A one-dimensional mathematical model for advective-dispersve transport and for irreversible and reversible bacterial kinetic sorption was used to analyze the bacterial breakthrough Different sorption parameters were obtained for each strain in each of the three experimental setups. In the presence of other bacteria, sorption parameters for B. cepacia G4PR1 remained similar to results from individual experiments, indicating the presence of other,. bacteria generally had a lesser influence on its migration than for the other bacteria K oxytoca is more competitive for the sorption, sites when simultaneously injected with the I other bacteria. Ps. sp. #5 generally yielded the greatest detachment rates and the least affinity to attach to the sand, indicative of its mobility in groundwater systerns. The results of this study clearly indicate both bacteria-solid and bacteria bacteria interactions influence the migration of bacteria. A more complete understanding of such interactions is necessary to determine potential migration in groundwater systems.
