Fractured Aquifers - Pollutant Transformations at the Groundwater - Rock Matrix Interface (P05)

断裂的含水层构成了世界饮用水资源的很大一部分，但往往容易受到硝酸盐或杀虫剂等污染物的污染。在这个项目中，我们将确定裂隙含水层中颗粒的组成、大小和来源，并确定它们对污染物传输和微生物群落组成的影响。我们将评估S和C元素循环(如HS-或CH4的氧化)和非生物过程(如化学脱氮作用)与反硝化的相关性。最后，我们将使用分子生物学方法(包括Omics)来确定含水层中石器时代和断裂相关微生物的位置、身份和新陈代谢。

Fractured aquifers constitute a large part of the world’s drinking water resources but are often vulnerable to pollution by contaminants such as nitrate or pesticides. In this project we will identify the composition, size and source of particles from the fractured aquifer and determine their effects on pollutant transport and microbial community composition. We will evaluate the relevance of S and C elemental cycles (i.e. oxidation of HS- or CH4) and abiotic processes (e.g. chemodenitrification) for denitrification. Finally, we will determine the location, the identity, and the metabolisms of endolithic and fracture-associated microorganisms in the aquifer using molecular biological methods (including Omics) applied to samples from drilling campaigns.
