Abstract  
Considering the issues of human interaction with the environment, there is often a need to know the permissible limits of impacts under which the natural-technogenic system does not leave a stable permissible state. This applies to the most diverse areas of scientific and practical activity in natural or human-modified environments. For example, in geotechnics - it is necessary to know the limits of static and dynamic loads on soils, resistance to shear and other stresses; in hydrogeology - to additional infiltration feeding of groundwater, pressure gradients; in thermal physics - resistance to temperature effects. That is, it is necessary to assess the permissible limits in a wide variety of areas of physical interactions in the "human - environment" system.
In geotechnical, hydrogeological surveys for construction, the maximum permissible indicators of significant impacts are determined and taken into account in each specific case. Then measures are taken to regulate (limit) the intensity of impacts or to increase the ability of the object to perceive and withstand these impacts. In general, this approach is an elementary control of a cybernetic nature.
However, at the current level of development of our civilization, it is required to move from cybernetic control methods to synergistic ones, that is, to the harmonization of interactions in controlled systems. In this case, a human should not be a primitive consumer, but act as a system-forming element that harmoniously interacts with the environment. We assume that in order to achieve such an engineering and environmental goal, it is necessary to introduce new concepts of a general (methodological) level into science and education. As such, we proposed the concept of «sustainability resource to external influences", which allows us to combine the consequences of a variety of activities by laws of a general (high) level.
Based on our many years of experience in surveying geotechnical and hydrogeological works in Ukraine, we have systematized and considered the main processes of changes occurring in the upper part of the underground hydrosphere. Their main number is observed in urban and industrial agglomerations and is almost always associated with engineering, construction and economic activities of a human. An analysis was made of the causes of such changes and the consequences, which are often sharply negative.
