| Sumario: | We studied quality of water of centralized water supply sources by microbiological and sanitary chemical indices in Aldansky, Khangalassky and Megino-Kangalassky districts of Sakha (Yakutia) Republic. The article presents comparative assessment with the same indices of Sakha (Yakutia) Republic. Statistical accountforms of the Center of Hygiene and Epidemiology in Sakha (Yakutia) Republic were used for the analysis. 14133 water samples were analyzed during 2006-2012. It was showed that the mostfavorable situation of the conformance to the sanitary chemical indices of water samplesfrom centralized water supply sources was in Aldansky district (specific density of unsatisfactory samples was 7,9 % and was lower than in the republic as a whole). The highest percentage of irregular samples of water exceeding the level of Sakha (Yakutia) Republic was registered in Khangalassky district (32,3 %). This index in Megino-Kangalassky district was at the level of the republican one (14,1 %). In long-term period in Aldansky district the dynamics of decrease ofunsatisfactory by microbiological indices samples of water that reflects situation in Sakha (Yakutia) Republic as a whole; in Megino-Kangalassky district we registered increasing dynamics. The highest specific density of water samples irregular by sanitary chemical indices was revealed in Khangalassky and Megino-Kangalassky districts (41,8 % and 29,2 % respectively); the lowest - in Aldanky district. In long-term period number of water samples inconsistent to the hygienic standards by sanitary chemical indices was defined by the increase in the other half of analyzed period. |
