Abstract

Phages, such as MS2, would be ideal indicators for the presence of enteric viruses in wastewater residues because of their ubiquity, nonpathogenic nature, low cost and time associated with their detection. The findings of this study suggest that MS2 could serve as an indicator for monitoring the persistence of enteric viruses, such as HM-175 and T1 L, during alkaline stabilization performed at moderate temperatures (28 degrees C), but may not serve as an indicator for HM-175 at reduced temperature (4 degrees C). The utility of MS2 as an indicator of viral persistence during biosolids treatment should be further evaluated, as the increased efficiency and frequency of pathogen monitoring associated with their use may reduce the potential public health risk associated with biosolids, facilitating a greater acceptance for their land application.
