Method of Assessing the Environmental Hazard for the Subsequent Use of Municipal Solid Waste Landfills

A method for assessing the residual environmental hazard of reclaimed municipal solid waste (MSW) landfill sites based on the detection of geoecological anomalies using the Isolation Forest methodology is presented. The proposed approach is shown to be an effective tool for the automated detection of anomalies in environmental monitoring data collected at MSW landfill sites. It enables the rapid identification of operational irregularities and supports timely implementation of measures aimed at localizing and mitigating adverse environmental impacts. The study concludes that the proposed method facilitates long-term emission management and minimizes accumulated environmental damage during the post-closure use of reclaimed landfill areas.
