In order to quantify anthropogenical influences, the studies concentrate on deeper groundwater in its structure as final result of a complex biogeochemical development from rain to seepage and the young groundwater close to the surface, and this development is analyzed in its individual steps. Laboratory experiments under controlled boundary conditions as well as field research above all are suited to broaden the state of knowledge; there is however much emphasis given on the parallel investigation of both paths. The number of test sites is limited, thus always leading to interdisciplinary studies of the investigated regions, with a comprehensive view at long-term effects of anthropogenical influences. A substantial part of the studies must always be the development of conceptual models and their conversion into computer models, since only with support of these models a prediction of long-term effects will result in controllable and transferable results. The studies in this priority programme are restricted to three main groups of dissolved constituents: natural organic matter, anthropogenical organic matter, environmental relevant metals.

为了量化地质影响，研究集中在其结构中的深层地下水，作为从降雨到渗漏的复杂地球化学发展的最终结果，以及靠近地表的年轻地下水，并在其各个步骤中分析这种发展。在受控边界条件下的实验室实验以及实地研究都适合于扩大知识的状态;然而，这两条路径的平行调查得到了很大的重视。试验地点的数量是有限的，因此总是导致跨学科的研究调查地区，在长期影响的综合观点的遗传影响。研究的很大一部分必须始终是概念模型的开发及其转化为计算机模型，因为只有在这些模型的支持下，对长期影响的预测才会产生可控且可转移的结果。这一优先方案的研究限于三大类溶解成分：天然有机物、生物有机物、与环境有关的金属。
