摘要

Groundwater in the discharge area of former ammunition production facilities often reveals severe contamination by production residues and waste products. Thus, these can cause health hazard to human beings in case untreated water is consumed. The investigation of the WASAG explosives plant in Haltern, Germany, revealed lack of scientific knowledge about retardation of nitroaromatic compounds. In this case study we have to deal with a more than 1.65 km elongated contamination plume consisting of various nitroaromatic compounds such as trinitrotoluene, dinitrotoluenes, dinitrobenzens, dinitronaphthenes and various degradation compounds coming from a former production area used for military production during times of war. There, from 1918 until 1922 waste waters from dismantling ammunition were sunk into a deep-reaching extended aquifer of high permeability. Therefore, a laboratory investigation program with column tests was initiated. First results reveal that retention and release processes as well as degradation mechanisms play a considerable role determining the velocity of transportation of contaminants. There is a strong correlation of the retardation coefficients of the nitroaromates with the content of silt, clay and organic substances in the soil. Even very small contents of these substances cause a significant increase of retardation factors. Also, the retardation factors of different nitroaromatic compounds vary in a wide range.
