[The sanitary parasitological characteristics of different sources of drinking water supply].

In some CIS areas (Khabarovsk Territory, Moscow, Grodno, Odessa, Astrakhan, and Kzyl-Orda provinces), sewage, animal sewage, and sewage from the populated areas (82.3% of the samples tested), water in the surface reservoirs, sources of potable water supply (54.0%), and potable water (6.5%) were shown to contain viable agents of intestinal parasitic diseases, such as cysts of Lamblia and Balandia, eggs of ascarides, Trichuris trichiura, Diphyllobothrium, oncospheres of Taenia, etc.). This should be borne in mind in planning and implementing measures for sanitary protection of surface and underground potable water supply sources, recreational [correction of recreative] areas, for prevention of helminthiases and intestinal protozoan [correction of Proteus] infections.
