This study was aimed at determination of the influence of an old municipal landfill site on the pollution of soil and groundwater by heavy metals. The impact assessment was conducted on the bases of piezometric recording, laboratory tests and site investigation, which gave information on the contamination level and direction of the pollutant migration. Based on the groundwater monitoring results, maps of heavy metal distribution and migration paths within the landfill surroundings were provided. The monitoring data show improvement in water quality in almost every piezometer after only a few years, since the soil–water protection system, including a vertical barrier and dewatering systems, has been installed at the site. This indicates that the reduction in heavy metals within the vicinity of the landfill is continuously progressing in time. On the basis of the obtained results, the magnitude of variability in pollutant migration and changes in concentration, as well as the efficiency of the vertical barrier, were assessed.

波兰修复后的垃圾填埋场中的重金属污染

这项研究旨在确定一个旧的城市垃圾填埋场对重金属污染土壤和地下水的影响。影响评估是在测压记录，实验室测试和现场调查的基础上进行的，这些信息提供了有关污染水平和污染物迁移方向的信息。根据地下水监测结果，提供了填埋场周围环境中重金属分布和迁移路径的地图。监测数据显示，由于现场安装了包括垂直屏障和脱水系统在内的土壤-水保护系统，因此仅在几年后几乎每个压力计的水质都得到了改善。这表明，垃圾填埋场附近的重金属的减少正在持续不断地进行。
