Virus transport in groundwater is controlled mainly by attachment onto the solid matrix andinactivation. Therefore, understanding how the various parameters affect virus attachment can lead toimproved virus transport predictions and better health risk evaluations. This study is focused on theattachment of viruses onto quartz sand under batch experimental conditions. The bacteriophagesFX174 and MS2 were used as model viruses. Three different sand grain sizes were employed for thestatic and dynamic experiments. The batch sorption experiments were performed under staticconditions at 4 8C and 20 8C and dynamic conditions at 4 8C. The experimental data were adequatelydescribed by the Freundlich isotherm. It was shown that temperature significantly affects virusattachment under static conditions. The attachment of both MS2 and FX174 onto quartz sand wasgreater at 20 8C than 4 8C. Higher virus attachment was observed under dynamic than static conditions,and in all cases, the affinity of MS2 for quartz sand was greater than that of FX174. Furthermore, in mostof the cases considered, bacteriophage attachment was shown to decrease with increasing quartz sandsize.
