Abstract

Groundwater protection from microbial contamination necessitates a solid understanding of the factors controlling the migration and retention of pathogenic organisms (biocolloids) in the subsurface. Although coliform bacteria and coliphages are used worldwide to indicate fecal pollution of groundwater, their transport behavior is not fully understood. This study focuses on the transport behavior of three waterborne pathogens (Escherichia coli, MS2, and ΦX174) in laboratory-scale columns packed with clean quartz sand. Three different grain sizes and three pore water velocities were examined. The attachment behavior of Escherichia coli, MS2, and ΦX174 onto quartz sand was evaluated. The mass recoveries of the biocolloids examined were shown to be proportional to the sand size, and they were shown to be highest for Escherichia coli and lowest for MS2. The single collector removal and collision efficiencies were quantified using the classical colloid filtration theory.
