Assessment of the Phosphates Content in Drinking Water of Segregate Draw-Wells and Chink in the Kyiv Region

The pollution of water ecosystems is a huge danger to all living organisms and, in particular, to human beings. The greatest threat is chemical pollution, which is tied with various substances penetrating of inorganic and organic origin in the water. Among such substances are selected phosphates.
