Under unusual conditions, where the raw water supply contains large amounts of sewage or where there have been mechanical or human failures in water treatment plant operation, waterborne disease may result. Under normal conditions of raw‐water supply and of adequate treatment plant operation in this country, however, the pathogenic bacterial and virus content in drinking water is below the infectious level when the Standard Methods coliform test shows no gas in any tube. The scarcity of waterborne disease outbreaks supports this view. Indicator organisms discussed include coliforms, fecal coliforms, and fecal streptococci. Treatment methods discussed for the removal of organisms include flocculation, filtration, and chlorination.
