ABSTRACT
Seasonal enumeration ofsomatic coliphages (SC), total coli/orms (FC),
faecal coli/orms (FC) and faecal streptococci (FS) has been performed in
different wastewater polluted water source points at and near the eastern
treatment plant in Alexandria. Somatic coliphages were detected in all
collected samples. A highly significant correlation was found between
counts of SC and either TC or FC but not FS in all seasons tested.
Predictive curves that could allow the assessment ofSC counts from TC,
FC or FS counts and vice versa have been constructed. Difftrent
hydrochemical parameters ofthe water samples were measured. -Stepwise
multiple regression analysis was used to rank various parameters based
on their effect on counts ofsomatic coliphages.
