The work analyzes data of environmental geological mapping, groundwater monitoring of the region municipal waste landfill. This study examines the effectiveness of a modern landfill liner system in minimizing migration of pollutants in the groundwater of an open hydrogeological system. The results showed that dissolution of carbonates and dilution were the major processes controlling groundwater quality. In the landfill’s direct impact zone, groundwater was only weakly polluted with biogenic components. Increase in concentrations of these chemical components in this zone was related with the groundwater and surface runoff water flowing from adjacent areas. We can state that the modern landfill liner system we analysed is efficient and has no adverse effects on groundwater quality under hydrogeological conditions favourable for the spread of pollutants. However, in case of an accident, pollutants might pose a great threat on the safety of groundwater. Therefore, even modern landfill liner systems are not recommended to be constructed in open hydrogeological systems.

现代垃圾填埋衬砌系统在控制开放式水文地质系统地下水质量方面的有效性,立陶宛

该工作分析了该地区城市垃圾填埋场的环境地质填图、地下水监测数据。本研究检验了现代垃圾填埋场衬砌系统在最大限度减少开放水文地质系统地下水中污染物迁移方面的有效性。结果表明,碳酸盐的溶解和稀释是控制地下水水质的主要过程。在垃圾填埋场的直接影响区,地下水仅受到生物成分的微弱污染。该区这些化学成分浓度的增加与从邻近地区流出的地下水和地表径流水有关。我们可以说,我们分析的现代垃圾填埋场衬砌系统是有效的,并且在有利于污染物扩散的水文地质条件下对地下水质量没有不利影响。然而,一旦发生事故,污染物可能对地下水的安全构成巨大威胁。因此,即使是现代垃圾填埋场衬砌系统也不建议在开放的水文地质系统中建造。
