Abstract


In order to create the basis for systematic environmental monitoring and eventual remediation procedures, at sites potentially contaminated by different activities, qualitative and quantitative determination of soil and groundwater contamination status must be carried out.

Although European Union has not regulated the area of ​​soil protection by a separate directive so far, the requirements for protection of this environmental component are set in other regulations, in particular the Directive 2004/35/EC on environmental liability with regard to the prevention and remedying of environmental damage and the Directive 2010/75/EU on industrial emissions. Mentioned acts clearly define the activities which can cause environmental damage and therefore are responsible for prevention measures application and remediation.

Given that Croatian regulation prescribes only the methodology for monitoring soil quality of agricultural land, underground contamination analysis described in this paper represents an example of pollution risk assessment at sites that do not meet the agricultural land standards. The selected site is connected with oil and gas production activities for many years. On the basis of field research carried out by authorized companies, involving soil and water sampling and laboratory analyzes, and in order to obtain a clear picture of pedosphere status and to make the conclusions regarding further monitoring, the maps of spatial distribution of pollutants are done in this paper.
