The authors consider the ecological state of waters and soils in the Nizhnyaya Kama National Park situated on the territory of Elabuga and Tukai administrative districts of the Republic of Tatarstan. There is a potential risk of man-made impact on the ecological system associated with development of the Pervomaiskoye oil field located within the National Park boundaries. When the National Park was established in 1991, the oil production facilities located in the conservation area were neglected, so to be able to continue oil production operations, Tatneft has been committed to mitigation of the environmental hazards and improvement of environment in the conservation area. The National Park and Tatneft have jointly worked out forest management regulations providing for environmentally responsible management on the protected area. This paper shows the water and soil monitoring sites (water springs, lakes, swampy hollows, and soil sites) located in the areas of potential environmental risks, and the sampling points located close to main pollutant sources. Samples are taken on a regular basis all the year round. The paper presents results of chemical-analytical surveys on determination of concentrations of pollutants in soil and water for the period from 2009 to 2017. Based on the results of surveys and analyses, it can be concluded that underway is the process of restoration of soils on the recultivated lands. The current state of surface and subsurface water and soils on the territory of the Nizhnyaya Kama National Park has been assessed. References 1.
