CRYPTOSPORIDIUM: A Drinking Water Supply Concern

This document is a review of the literature concerning the protozoan CrvDtosDoridium. Several waterborne outbreaks of Cryptosporidiosis have occurred over the past ten years in the United States and a great deal of concern has been raised about this organism and drinking water supplies. Sections of the document cover the background, organism, occurrence in water, regulation and research needs of CrvetosDoridium. Current information on CrvDtosDoridium indicates we have only a limited knowledge of this organism. The parasite is very small (2 to 6 pm) and is found in all types of surface water throughout the world. CrvDtosDoridium shares some of the same characteristics a Giardia, but inactivation and removal appear to be much more difficult to achieve for CrvDtosaoridium
