Methodology for Quality Assurance of Groundwater Resources Exploitation Within Belgorod Region

Abstract

The purpose is to analyze the ecological and hydrogeological situation of the territory of the Belgorod region and develop a system of measures to ensure its environmental safety. Materials and methods. The research methods include a complex of field route studies and analysis of modern approaches to hydrogeological drilling of wells. In the process of route studies, wells were recorded, their external condition was described, and groundwater was sampled. A visual examination of the surface of the water in the wells was noted, the color of the water and the smell were determined. Hydrogeological drilling was evaluated according to the following parameters: structural design of construction and arrangement of hydrogeological wells, composition and quality of drilling mud, sprinkling of the filter with gravel mixture, possible curvature of the borehole, recorded accidents, loss of mechanical drilling speed, loss of the working diameter of the well, etc. Results and discussion. In the course of research, an unfavorable state of surface water supply sources was revealed, which accounts for about 60% of all wells. Abandoned wells with an externally positive condition are littered with construction debris, animal remains. This circumstance creates high levels of danger for productive aquifers and complexes. In the process of analyzing the state of hydrogeological drilling production within the Belgorod region, problems of environmental hazard were identified and a set of technical and organizational measures to eliminate them was formed. These included: an appeal to the Ministry of Natural Resources and Ecology with an initiative to license drilling activities; the use of an expander (copyright patent No. 138113 dated 9.07.2013) and a container (copyright patent No. 194762 dated 18.06.2019) when pouring gravel into filters; the introduction of regional grants in the direction of "Saving the well"; inclusion in the system of regional environmental monitoring of objects that have undergone the procedure of cleaning and renovation, etc. Conclusions. It is emphasized that the quality of aquifers used for economic and drinking purposes largely depends on two indicators: the condition of wells that open groundwater; technologies and equipment quality of hydrogeological wells that open deep aquifers and complexes. It is indicated that it is very effective to involve schoolchildren and members of environmental public organizations in the problem of polluted wells. A set of methods and methods for ensuring the environmental safety of water-bearing units has been developed, including a number of technical and organizational measures that will significantly improve the negative aspects of the existing water supply in the Belgorod region.
