AbstractBiological contamination of environmental objects was monitored in 245 monitoring points of the region according to the monitoring observation program. In 2005-2008, the proportion of drinking water samples from the distributing network of household water supply systems, which meet no hygienic standards, is 1.3 to 1.8% and the proportion of those from non-centralized water supply sources is 6.2%, which is due to a weak protectability of aquifers from their surface contamination. Comprehensive assessment of household water supply factors has indicated that water preparation and transportation are key links in the formation of household water supply problems.
