Kazan, the settlement Oryol . if the artist’s brush, inscribed in the local landscape, carefully preserving every tree, growing on a plot surrounded by a perimeter forest of birches, pines and, of course, oil.
It’s amazing how just 20 minutes a comfortable move from the town centre on the modern highway in the direction of Borovoye i.e. rivers, 23 km from RCB, you find yourself in a very special world, where you want to grow your children, where you can breathe clean air, where one can enjoy the peace and tranquility of country living.

The Hydrogeological setting of the karst massif of rocks determines the intensity of modern cestovanie. Gipsoangidritovye for the array characterized by the distribution of karst waters in the upper zone. The maximum-flooding zone pridelines. Under the upper Permian rocks sharply decreases. Water pressure, fissure-stratal and fissure-karst, the absolute level of 20-70 m. In terms of nutrition, movement and discharge of karst water area belongs to type III hydrodynamic sulphate karst (Gorbunov, 1979), which is characterized by the preferential development zones vertical, transition and horizontal circulation of karst waters. The thickness of the zone of intensive water exchange of 30-50 m in the raised area of the white sea-Kuloyskoe plateau up to 100 m. over developed in the watershed areas of the absorption apparatus field of sinkholes, surface waters get deep into the array, where the concentrated form of underground streams – a karst-paleogeodynamics system. The path of the underground transit from the site of absorption to areas of discharge of short duration – to 10-15 km, normal discharge in the form of descending or ascending sources in the estuarine areas of caves, marked by massive and subaqueous karst water outputs. Groundwater salinity mainly sulphate-calcium, high water Continue reading
