The article focuses on the experiments to determine the distance and flow effects on microsphere transport in a large gravel column. There is a need to understand the processes in the pathogen transport in aquifers because of the possible adverse effects of consuming groundwater that is microbially contaminated. Microspheres with a conservative tracer, bromide, were used in the experiments. In coarse gravels, colloid concentration is log-linearly related to transport distance. An inverse relationship exists between transport distance and colloidal transport.
