ABSTRACT

Polluted water can transmit lots of pathogens with various behaviors and resistances. Among the pathogens, the parasites are particularly important since they stand out for their high resistance to various environmental factors in addition to being associated to high morbidity and mortality rates in the developing countries, particularly children. The objective of this paper was to highlight the importance of health surveillance of parasites in water quality according to use and its relationship with the environment. The helminth eggs are the main health risk due to the safe use of wastewater or sludge in agriculture. Protozoan cysts like Cryptosporidium and Giardia, are difficult to remove from untreated drinking water due to its small size and resistance to commonly used oxidants such as chlorine. Although the routine monitoring of these cysts in water is not recommended, it is necessary to conduct research to detect its presence and to establish suitable guidelines according to our conditions.
