The paper presents the results of three hydrochemical surveys performed in October 2000 and May and July 2001 and microbiological monitoring performed in June, July, and August 2001 in Vostok Bay (Sea of Japan), which is a favorite recreation area for the inhabitants of Primorye and the Russian Far East. It is shown that at the height of recreation occurs during late summer, as determined by the concentration of water-dissolved oxygen, the biochemical oxygen demand (BOD5 ), the concentration of detergents, and the number of colony-forming enterobacteria in 1 ml of water. However, in autumn, especially by October, the anthropogenic pressure decreases and the quality of the water environment in the bay improves.
