An environmental project evaluates application of airborne multisensor survey for assessment of various contaminated sites. Combination of magnetic, radiometric and dual frequency electromagnetic methods mapped in detail contaminated targets at a test area in eastem Germany. The radiometric data mapped effectively the impacts of uranium mining. Magnetic and EM data described well the landfills and tailing ponds even when they were buried. Additionally the measurements revealed new information of previously unknown possibly contaminated sites, The airborne EM method proved to be useful for assessing groundwater contamination in the vicinity of environmental risk targets. The interpretation of AEM data is validated by geophysical ground measurements and improved using numerical modelling with detailed and precise modeIs.
