A retrospective review of the groundwater monitoring development in the world and particularly in Ukraine is presented here. The need to intensive study of the changes in the drinking groundwater quality in the 50-ies of the last century has been associated with an increase in water consumption and increasing a reset of untreated waste water. However, it took another 10-15 years until the world drew attention to the spilled oil as a specific pollutant of underground hydrosphere. Among articles dealing with the groundwater pollution problem, different publications have appeared which show examples of mapping of oil-contaminated sites, the implementation of specific monitoring, qualitative description of the formation of multi-phase accumulations of petroleum in the pore space, the mathematical migration models, etc. In the methodological recommendations for hydrogeological research of contaminated areas, which were used in the Soviet Union, oil pollution was referred, as a rule, only in connection with the migration of dissolved petroleum hydrocarbons. The same trend has been kept in Ukraine, at least until the mid 90s. In the 80-90 years in Ukraine the cases of detection of previously hidden in the ground the lost petroleum accumulations have become more common. The article gives examples of contaminated sites, in the study of which IGS NAS Ukraine participated. In the department of protection of groundwater IGS NAS Ukraine, the general concept of contaminated geological environment monitoring, methods and ways of solving monitoring tasks in various stages of research were formulated; the principle of risk assessment of an oil product pollution of natural and economic objects and creation around potential contamination source of warning zone and the location of observation posts in it was proposed.
