Hydro-geophysical investigation of landfill leachate and environmental impact at a closed municipal waste landfill in southwestern Ontario

垃圾渗滤液是地表水渗入垃圾时产生的渗滤液，对地下水和土壤构成潜在的污染问题。拟议的项目将集中于位于安大略省西南部的一个封闭的城市垃圾填埋场(SITE)，这将是温莎大学(UOW)和Genivar Inc.(Genivar)的合作努力，其中包括两(2)名研究生、一(1)名UOW教员和两(2)名Genivar的初级和高级人员，他们将协助审查和数据评估，以评估与现场垃圾渗滤液相关的潜在环境影响。封闭的垃圾填埋场覆盖着粘土盖子系统，并包括一个渗滤液收集系统，以及几个现有的地下水和渗滤液监测井。拟议的项目将采用一种创新的方法，将地球物理制图和地下水建模结合起来，以解决与工地盖层和渗滤液分布现状有关的具体研究问题。这一拟议研究项目的主要目标是提供研究结果，以评估和评价目前的渗滤液状况，并将新数据与现有的遵从性监测计划进行比较，以进一步评估在安大略省西南部的场地或其他场地可能实施的情况。研究结果将通过与Genivar的书面和口头交流分享。

Landfill leachate is formed when surface water percolates through the disposed wastes, posing a potential pollution problem for groundwater and soils. The proposed project will focus on a closed municipal landfill located in Southwestern Ontario (Site) and it will be a collaborative effort between the University of Windsor (UOW) and GENIVAR Inc. (GENIVAR) that includes two (2) graduate students, one (1) UOW faculty member and two (2) GENIVAR's junior and senior personnel who will assist in the review and data evaluation to assess the potential environmental impacts associated with landfill leachate at the Site. The closed landfill is covered with a clay cap system and includes a leachate collection system with several existing groundwater and leachate monitoring wells. The proposed project will employ an innovative methodology that combines geophysics mapping and groundwater modeling to address specific research questions related to current conditions of the cap and leachate distribution at the Site. The main objectives of this proposed research project are to provide the research findings to assess and evaluate the current leachate conditions and to compare the new data with the existing compliance monitoring plan for further evaluation for potential implementation at the Site or other Sites in Southwest Ontario. The findings will be shared through written and oral communications with GENIVAR.
