Abstract
It was established that the major pollutants of the river system at the territory of developed deposits in the Tomsk Region are oil and petroleum products the content of which in water exceeds the maximal permissible concentrations. It was demonstrated that space photographs and the data of remote probing Landsat and ASTER GDEM, SRTM may be used for the purpose of mapping the zones of oil spill, to determine the risk of pollution of water bodies, and to calculate the module of petroleum product washout from polluted basins in order to determine the total annual income in the river system.
