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

垃圾填埋场渗滤液是地表水通过垃圾处理后产生的，对地下水和土壤构成潜在污染。 拟议项目将集中在位于安大略西南部（场地）的一个封闭的市政垃圾填埋场，这将是温莎大学（UOW）和GENIVAR公司之间的合作努力。（GENIVAR），包括两（2）名研究生、一（1）名UOW教职员工和两（2）名GENIVAR的初级和高级人员，他们将协助审查和数据评估，以评估现场垃圾渗滤液的潜在环境影响。 封闭式垃圾填埋场覆盖有粘土盖系统，包括一个渗滤液收集系统，现有几个地下水和渗滤液监测威尔斯井。 拟议的项目将采用一种创新的方法，结合地球物理学测绘和地下水建模，以解决与现场盖帽和渗滤液分布的当前条件有关的具体研究问题。 本拟议研究项目的主要目的是提供研究结果，以评估和评价当前的渗滤液状况，并将新数据与现有合规性监测计划进行比较，以进一步评价现场或安大略西南部其他现场的潜在实施情况。 调查结果将通过与GENIVAR的书面和口头交流进行分享。

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.
