Abstract
Over 60 outbreaks of waterborne giardiasis occurred in the United States between 1965 and 1982, mainly in the Northeast, the Rocky Mountain states, and the Pacific states. Outbreaks most often occurred as a result of inadequate or interrupted treatment. Disinfection problems and failure to provide filtration were noted in a majority of treatment-related outbreaks. Inadequate coagulation and poor filtration practices were identified as problems where treatment was provided. Recent research has shown the sort of treatment practices that can permit Giardia cysts to pass through treatment plants as well as what is needed to provide effective barriers to the cysts.
