Abstract
The oil-product pollution of the outlet section of the Kamchatka R. rapidly increased in 2001–2002. Within nine years out of ten in the period from 1992 to 2001, oil products were not found there; however, since 2003, their annual mass transported every year rose above 2.5 thousand t. Therefore, the authors analyzed the available integral data on this river pollution and launched a screening study of the pollution of its tributaries. The obtained results confirmed the assumption regarding an abrupt growth: the pollution in 1992–2001 was many times less than that in 2002–2021. The transport through the outlet section increased from <1500 to 6400 t/year (the mean value). This pollution is supported by the major portion of tributaries in a considerable segment of the river. Field studies suggest a conclusion that the total input of oil products into the Kamchatka R. can reach 30–40 thousand t per year. A study of the effect of a plugged exploration well shows that it is a source of oil pollution. The number of permits issued over 28 years for exploratory drilling in one of the areas, a significant part of which is located in the Kamchatka River basin, reliably correlates with the mass of oil products transported through the outlet section. Therefore, the inflow of oil into water from exploration wells may be among the main causes or the main cause of the jump-like growth of pollution. Such results were obtained using several integral approaches, including an effective one—establishing a relationship between the natural and administrative characteristics. In order to reduce the pollution of one of the largest spawning rivers in Russia, it is necessary to continue studying, to carry out mapping its main sources, and subsequently eliminate them.
期刊介绍：
Water Resources is a journal that publishes articles on the assessment of water resources, integrated water resource use, water quality, and environmental protection. The journal covers many areas of research, including prediction of variations in continental water resources and regime; hydrophysical, hydrodynamic, hydrochemical and hydrobiological processes, environmental aspects of water quality and protection; economic, social, and legal aspects of water-resource development; and experimental methods of studies.
