Head of Department: Candidate of geological and mineralogical Sciences S.P. Dzhepo

Scientific secretary candidate of physics and mathematics Sciences I.P. Onyshchenko


Department consists of 10 staff members, four of them have a scientific degree of candidate of sciences. The department was created on 06.12.1995 according to the decree of the Presidium of the National Academy of Sciences of the Ukraine № 264 from 10.18.1995.

The staff of the department develop the following main scientific and applied research directions: - development of systems of the hydrogeological monitoring for radioactively contaminated sites and ecologically-hazardous facilities; - study and mathematical modeling of moisture flow in the vadoze zone, groundwater flow and migration processes of radionuclides and chemical contaminants in geological environment; - risk assessment for radioactive contamination of ground water; - improvement of laboratory and field methods for study of moisture flow  in soils of vadoze zone; - special   hydrogeological investigations in connection with the impact of the hazardous geological processes (such as surplus moistening of soils, landslide processes) on historical-architectural sites and buildings.

Researches of the Department of monitoring of geological environment territorially take place at the following sites and objects: - the Chernobyl Exclusion  Zone and objects of the ChNPP; - the Prydneprovskyy Chemical Plant  and its tailings (Dneprodzerzhynsk city, Dnepropetrovsk Region); - Kiev historical-architectural sites (Sophia Kyevskaya, Kyryllovskaya Church, Kyevo-Pecherskaya Lavra monastery).

During the period of existence of the department the following main scientific and practical results were achieved: - the regional-scale system of the hydrogeological monitoring for the Chernobyl Exclusion  Zone (ChEZ) was designed, - the regional three-dimensional mathematical model of groundwater flow for the ChEZ was developed; - within the framework of an international cooperation with the IRSN institute (France) an experimental polygon site for monitoring of the processes of migration of radionuclides in the ground water at the  «Red Forest» radioactive waste site in the ChEZ was created, where since 2000 comprehensive hydrogeology researches and monitoring studies were conducted; - long-term predictions and risk assessment of radioactive contamination of groundwater in the ChEZ were carried out (regional assessments, and also assessments for the main individual radioactively-hazardous sites); - the methodology and criteria for decision making for the water protecting measures in the ChEZ were developed; - experimental hydrogeological researches were carried out,  filtration and migration models were developed and strategy for managing the cooling pond on the stage of decommissioning of the ChNPP was worked out (regarding the hydrogeological aspects of this problems).

Since 2005, comprehensive hydrogeological researches and groundwater modeling predictions for the Prydneprovskyi chemical Plant site (PChP) and its facilities were carried out:  - the monitoring well network and protocols of the hydrogeological monitoring for the PChP territory were designed; - regional-scale filtration model and local-scale migration models for the industrial site of the PChP and for the site of the “Sukhachevskoe” uranium mill tailings (first and second section)  were  developed;  - hydrogeological predictions were carried out and the radiation risks of migration of  radionuclides of uranium decay series in groundwater were estimated; - long-term strategy for managing the PChP site and its tailings was developed.

In 2005-2010 the systems of the automated hydrogeological monitoring for historical-architectural sites of the Kiev City was developed and put into operation with the purpose of controlling and preventing the potentially hazardous geological processes; - the regime observations of meteorological parameters, groundwater levels, regime of moisture content in unsaturated soils were conducted; - recommendations  on protection of historical-architectural sites were developed (for the buildings of the Sophia Kyevskaya cathedral, caves and territory of garden above the caves of the Kyevo-Pecherskaya Lavra monastery).

During last years the Department is involved on regular bases in scientific collaboration with such international institutes and organizations as Institute of Radiation Protection and Nuclear Safety (ІRSN, France), University of   Nimes (France), French National Council on Scientific Researches (CNRS), Swedish Agency on Radiation Protection (SSM), International Agency of Nuclear Energy (IAEA, Vienna, Austria), and others.

During time of its existence the staff of the Department contributed to the publications of 8 monographs and more than 60 scientific articles, practically every year the staff of the Department present papers at several national and international scientific conference.
