Abstract
Objective. To study and carry out the retrospective analysis of water contamination with helminth-protozoan infestations in Astrakhan Region for 2010-2019.
Materials and methods. During the analyzed period, 80962 samples taken from environmental objects were examined.
Results. The percentage of samples that did not meet sanitary and parasitological indicators was 1.2 % (951 samples). The proportion of water samples collected and examined for parasitological parameters (eggs and larvae of helminths, cysts of pathogenic intestinal protozoa and oocysts of cryptosporidia) was 7.5 % (6033 samples). Water samples were taken from various water sources: water from centralized water supply, water from swimming pools, water from open reservoirs, waste water, water from wells, and bottled water.
Conclusions. To conclude, the results were obtained indicating that the absence of positive findings in water samples from central water supply facilities indicates a high-quality filtration and prevention of these objects; the presence of cysts of dysentery amoeba and dead strongylid larvae in water samples, swimming pools, as well as the presence of eggs and larvae of helminths and cysts of pathogenic intestinal protozoa in open reservoirs, indicates fecal contamination of these objects; the presence of positive findings in samples of wastewater and water from wells shows that reliable deworming and disinfection of wastewater is not provided at these facilities.
