Long-Term Multivariate Screening of a Recirculating Landfill Leachate Circuit: Pollutant Dynamics, Statistical Structure and Associated Risk to Biota
Landfill leachate circuits that operate without discharge, by recirculating aerated leachate onto the waste mass, are widespread in South-East Europe, yet their long-term behaviour is rarely documented with sample-level data. This study reports a six-year (2020–2025) seasonal monitoring campaign at a sanitary landfill...
