Security Risk of Landfill Gas - Hazard Potential and Defensive Measures

The aim of the project is to evaluate the potential hazards and to analyze defensive measures. For this purpose, first the potential for harm in Austria was investigated in a first survey step. Informations of all landfills and contaminated sites with organic content > 25,000 m 3 within Austria were collected and elicited whether and which buildings or critical infrastructure are located on or near the surfaces. The results were visualized by hazard maps. In a next survey step for the Federal State of Salzburg were documented not only recent landfills and contaminated sites, but also old landfills and suspected sites (possibly contaminated areas) with organic content and investigated whether and which buildings and critical infrastructure are located on or near the surfaces. The results were again visualized by hazard maps.
