Abstract

More than 100 types of human pathogenic viruses may be present in fecal-contaminated waters. Coliphages are used as indicators of virus-related fecal contamination and of the microbiological quality of waters. This report provides information on the equipment, sampling protocols, and laboratory methods that are in standard use by U.S. Geological Survey (USGS) personnel for the collection of data on fecal indicator viruses.
