Disposal of waste waters into subsurface started in 1930-1940 in the USA, after that it became customary almost in all countries, and, first of all, it aimed at maintenance of formation pressure during oil fields development. The method of waste waters disposal into subsurface is used at fields of Grozniy (Groznenskoye), in the republics of Turkmenistan (Kum Dag field), Azerbaidjan (Surukuny, Balakhany), Tatarstan (Romashkinskoye), Kazakhstan (Karachaganak, Tengiz), at Astrakhan, Orenburg, Urengoy and other fields. Therefore, development of new technologies for geological and environmental monitoring of subsurface state during waste waters and other production wastes disposal is crucial. It is known that waste waters are a mix of waters recovered together with oil and gas, or produced as a result of operational processes (drilling, preparation and processing of oil and gas) and which contain dissolved mineral salts, organic substances, mechanical impurities and bacteria.

Key words: Waste waters, disposal site, geological and environmental monitoring, hydrogeological characteristic, production level, waste waters front
