Groundwater protection becomes a matter of current interest only when a polluting incident occurs. Recently, different approaches to defining preventive measures have been developed in the domain of hydrogeological investigations. They mainly serve to evidence compliance with the legal regulations, while quality protection is undertaken only when a polluted area or endangered groundwater bodies have to be treated (e.,g. accidental contamination of: the groundwater in the Pozega railway station area, of the Belgrade water source from the direction of the Makis marshalling yard, of the "Medijana" water springs from the direction of the "Electronic industry" in the town of Nis, and especially the enormous environment devastation in the period of tragically NATO aggression for 11 weeks in the 1999’s spring).

It is known that expenses for preventive measures are 10 to 20 times lower than funds for investigations and treatment of polluted groundwater. Therefore, the first step in a rational approach to this problem should be to create an active groundwater quality monitoring system in the wide zones of all the existing and potential water springs, in the zones of big industrial facilities, spoil areas, petrol stations, storehouses for noxious and dangerous substances, and especially in prospective hydrogeological zones crossing or touching transport communications (roads, railway, gas, oil pipelines, etc).

This theme represents the most important activity of my team and of the Department of hydrogeology by the “Jaroslav Cerni” Institute, Belgrade where many of the experiences also references have been reached last years. So, take a look this presentation and do not hesitate to call if you have any inquiry or just to make a contact. You're welcome !!!
