The aim of the study was to assess the impact of a small municipal landfill on the aquatic environment over 9 years, using advanced statistical tools. The results of the study of surface, ground- and leachate waters from 2008 to 2016 were subjected to detailed statistical analysis based on 15 physicochemical indicators. Factor analysis accounted for the requirements of the WHO, the European Union and the nation of Poland using 8 statistical analytical methods. The analysis of leachate contamination from the landfill site with the use of advanced statistical tools revealed its interaction with groundwater. The assessment was based on increased and statistically significant values and correlations of temperature, Zn and N-NO between leachate and groundwater, factors demonstrating the negative impact of the landfill. In the case of Zn, there was also a correlation between the tested waters below the landfill. The increased PAH values in the examined surface and ground waters were not a consequence of waste disposal. However, the deterioration of the chemical state of groundwater in the vicinity of the landfill could result from a certain dysfunction of the facility's infrastructure after operating for more than 20 years.
本研究旨在利用先进的统计工具，评估小型城市垃圾填埋场对水生环境的影响，历时 9 年。本研究对 2008 年至 2016 年地表水、地下水和渗滤液进行了详细的统计分析，基于 15 项理化指标。使用 8 种统计分析方法，对渗滤液的因子分析结果进行了符合世界卫生组织、欧盟和波兰国家标准的评估。利用先进的统计工具分析垃圾填埋场渗滤液的污染情况，揭示了其与地下水的相互作用。评估的基础是渗滤液与地下水之间温度、Zn 和 N-NO 的增加和具有统计学意义的数值及相关性，这些因素表明了垃圾填埋场的负面影响。就 Zn 而言，在垃圾填埋场下方的测试水域之间也存在相关性。在所检查的地表水和地下水中，多环芳烃值的增加并非废物处理的结果。然而，在垃圾填埋场附近，地下水化学状态的恶化可能是由于该设施运营 20 多年后基础设施出现一定程度的故障所致。
