Vulnerabilities and risks induced by the emissions of non-compliant landfills after closure period. Case study

Abstract

Non-compliant landfills generated emissions over a long periods of time that may affect the quality of the environmental components in the vicinity. The conceptual model and the investigation model of the landfill analysed as a case study contain elements that permitted us to establish the environmental vulnerabilities and quantify the associated risks of the environmental components, as effects induced by the landfill. This paper presents the results of the investigations conducted that focused on groundwater, surface water, sediments from the river sampling, as well as samples of the natural surrounding vegetation; were analysed in the laboratory physico-chemical quality indicators for water samples and for the sediment samples were determined the biological indicators (MZB components). Finally comparative analysis of the results allowed us to quantify the environmental risks by route SOURCE – ROUTE OF TRANSMISSION – RECEIVERS of the environmental components studied and illustrated by a ‘tree diagram’ that highlights all aspects of adverse effects on the environmental components in the studied area.
