Hygienic aspects of water use of the population of the territory in the zone of influence of the Vostochny Cosmodrome

Abstract

There are presented the results of a hygienic assessment of the water quality of surface water bodies, the catchment basins of which are localized within the territory of the zone of direct influence of the objects of the Vostochny cosmodrome and the quality of drinking water from the distributing water supply network of the centralized water supply of ZATO Tsiolkovsky. Was carried out the analysis of the data of the regional system of socio-hygienic monitoring, including at the pre-operational and initial stages of operation of the Vostochny cosmodrome. The results obtained indicate that there are no excesses in priority pollutants in the water of surface water bodies (UDMH, NDMA, TMT, formaldehyde, oil products). Heavy metals were determined in concentrations significantly lower than the maximum allowable concentration for surface water bodies for cultural and domestic water use. The results of laboratory studies of drinking water in terms of organoleptic indicators corresponded to hygienic standards, with the exception of water at one monitoring point, where color and turbidity indicators increased by 1.8 and 4.8 times were recorded. Studies on the content of metals showed their presence in water at concentrations significantly lower than the hygienic standards approved for drinking water, with the exception of iron and manganese at two monitoring points, which may be due to natural regional factors.
