Sažetak
Unmanaged landfills are the basic problem of environment protection on Croatia. Municipal waste and landfills such as Jakuševac incur exceptionally high costs for many towns. Their impact on the environment is highly unfavourable since they pollute water, soil and air and represent a constant threat to human health. The solution to the problem begins with remediation of unmanaged landfills. To launch a remediation programme it is necessary to adopt a new attitude to waste management. The establishment of an integral waste management system is a constituent part of all legal measures and regulations. Such a system ensures the reduction of waste and increased recycling, which provides material and energetic benefits. In today’s circumstances, the implementation of the system at the level of the City of Zagreb and Croatia as a whole results in multiple benefits from both the ecological and economic aspect. The paper gives a survey of the Jakuševac landfill, a complex diffuse source of contamination which causes problems in the sense of possible harmful effect on all environmental elements. Consequently, its remediation was highly expedient. The main reasons for landfill remediation were the protection of groundwater and air. The Jakuševac-Prudinec landfill used to be a disposal site for municipal, non-hazardous and industrial waste of the City of Zagreb and its surroundings. Uncontrolled disposal of waste in the area of the current landfill began in 1965. In 1995, the size of the landfill reached 80 ha. In this period, 4.5 million m3 of waste was disposed inadequately. By the year 2000, the volume of the disposed waste had reached 8 million m3. The transformation of the unmanaged waste disposal site into a managed sanitary landfill was completed at the end of 2003. In the period from 1965 to the beginning of the 1990s, almost one million m3 of soil (soil material) in the Jakuševac-Prudinec landfill was contaminated, and the quality of drinking groundwater was seriously threatened. This research discusses the impact of the landfill on groundwater and the gradual spread of pollution eastwards, as confirmed by the shifting of the boundary pollution line from Jakuševac towards Mičevac, especially during changeable hydrodynamic conditions in the aquifer layer. The paper presents the results of research into the cause and effect relationship between the Jakuševac landfill and groundwater pollution (see Figures 1–5). The composition of organic pollutants in the Jakuševac landfill indicates that this was a disposal site not only for municipal waste but also for waste of industrial origin which contains numerous anthropogenic compounds that might have an adverse effect on groundwater quality. Permanent monitoring of dominant anthropogenic compounds in the disposed waste and leachate is necessary.
