Laboratory leaching tests may be used for source term determination as a basis for risk assessment for soil-groundwater pathway (leachate forecast) on contaminated sites in Germany. Interlaboratory comparisons on the evaluation of the reproducibility of column percolation tests were conducted within the framework of an integrated R+D program using three waste reference materials. The interlaboratory comparisons of column percolation tests showed good reproducibility of the results for inorganic and organic parameters as well as for the accompanying parameters. This is due to the stipulations concerning the time of contact between leachant and sample material as well as the sample placement in the columns. Different column dimensions used by the participants of the interlaboratory comparisons did not have any substantial influence on the column test results.
在德国，实验室浸出试验可用于确定源项，作为污染场地土壤 - 地下水途径（渗滤液预测）风险评估的基础。在一个综合研发项目的框架内，使用三种废物参考材料对柱渗滤试验的再现性评估进行了实验室间比较。柱渗滤试验的实验室间比较表明，无机和有机参数以及伴随参数的结果具有良好的再现性。这归因于关于浸出剂与样品材料接触时间以及样品在柱中的放置的规定。实验室间比较的参与者使用的不同柱尺寸对柱试验结果没有任何实质性影响。
