Monitoring the quality of superficial drain arriving in city reservoirs, having special value

The especially protected natural territories (EPNT) including water objects, lacking waters, were considered. The partial solution of this problem possibly due to accumulation of the superficial drain arriving from adjacent territories, and to its direction in reservoirs. Water has to meet certain sanitary requirements and norms. For the purpose of preservation the quality of water in reservoirs on EPNT due to receipt of a superficial drain, we conducted researches of chemical and physical composition of a rain and thawed drain.
