["Copy-pair" model for calculating the effect of the water factor on the health status of residents in an epidemiological study].
The paper presents the results of testing 4 main models of copy-pair examinations in some cities and towns of the country, which have been recommended for singling out the influence of a water factor on human health in epidemiological surveys. A locality with varying water supply (drinking water quality) in its different parts is shown to be methodologically the best model.
