THE DETERMINATION OF HAZARD FACTORS ACCORDING OF REGIME OBSERVATIONS FOR THE AQUIFER IN KARST AREAS.

The paper deals with the definition of the zones of influence of dangerous factors on regime observations for the aquifer in karst areas on the basis of experimental research in the area of recreation at the lake Big Holy Nizhny Novgorod region. On the basis of the geological section of the study area and the chemical analysis of groundwater, zones and objects with anthropogenic impacts on the aquifer identify. For the control of the aquifer in the recreation center information-technical complex of the geo-ecological monitoring of groundwater are used on the basis of multi-frequency method vertical electric sounding. The method is designed to detect changes in salinity and the level regime of the aquifer in the territory of decentralized water supply. The zones lesion study area by karst processes from route observations defined. In paper justified that at the control of the quality of the groundwater by geoelectric methods corrective amendments in the model parameters of the geodynamic models to introduce necessary. On the basis of the data revealed a previously unrecognized hazard, that are associated with unorganized leisure travelers. They use recreational resources of the lake, forming unauthorized places dumps of organic and inorganic content of the waste. When the spring flood period in areas of karst surface water and groundwater are accumulated, contaminants are infiltrated with the surface water precipitation and fall in ground water, changing their chemical composition, and increasing the overall mineralization.
