The purpose of this study was to develop and evaluate a simple membrane filter method for concentrating and enumerating F‐specific coliphages in raw and finished drinking water with a view to using these phages as a viral indicator. The method developed was field‐tested by determining the concentrations of F‐specific coliphages in several source waters and comparing them with concentrations of fecal indicator bacteria. The results suggest that the new membrane filter method for enumerating F‐specific coliphages should be useful for assessing fecal contamination of natural and treated waters. Additional studies are needed to determine whether these coliphages are reliable indicators of enteric viruses in water.
