[New methodical approaches in the projection of zones of sanitary protection of water sources].

In the projection of sanitary protection zones of water sources it is extremely important to determine the specific boundaries of the established zones of sanitary protection due to the solution of property issues and responsibilities. In the paper projection of data with account of required scaling it is not possible to do. In this case, the use of geographic information systems is appropriate and useful. In addition there is necessary an adjustment of the existing sanitary calculations in relation to zones of sanitary protection of water sources in the part of specification of the order of approval of projects of sanitary protection zones and organization of the control for their implementation.
