Underground waters of Astrakhan Caspian region as Р° part of the subsoil undergo the impacts mainly from industrial production, agriculture and communal services. Procuring of Astrakhan region in water for drinking and economic needs is not sufficient. Only in northern part of region underground waters are protected from the ingress of toxic substances. Development of the oil and gas sector offers prospects of a new threat to environmental safety of Astrakhan Caspian region. Drilling wastes which are stored in the sludge pits are the main source of pollution. Transportation of such waste is dicey. It can lead to contamination of the terrain by toxic substances. Thus, there exists a high probability of emergency of numerous unauthorized dumps of toxic drilling waste. It is necessary to analyze the available data on the geological structure to forecast the possible spread of toxic components and their impact on the environment and develop a system of monitoring wells around objects bearing potential danger for ecology of the region.

Key words: подземные воды, пресные воды, загрязнение, токсичные вещества, мониторинг, геологическое строение, underground waters, fresh water, pollution, toxic substances, monitoring, geological structure
