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

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.
