      Nitrate in groundwater

      Funding: 

      (Deutsch) Landwirtschaftlich ausgebrachter Stickstoff, als Mineraldünger und Gülle, ist die Ursache für hohe Nitratbelastungen im Grundwasser. In der Niederrheinischen Bucht ist der natürliche Abbau von Nitrat durch Reaktionen mit dem Gestein von besonderer Bedeutung. Wassergewinnungen aus solchen Gesteinen zeigen statt Nitrat die Ergebnisse der Rückhaltereaktion (z.B. Sulfat). Von großer wasserwirtschaftlicher Bedeutung ist die Frage, wann das Rückhaltevermögen der Gesteine hinsichtlich Nitrat erschöpft ist.

      Single fracture test facility

      Funding: 

      The single fracture test facility allows the experimental investigation of mass transport through fractures; accordingly, to enable transport investigations of metal, no metal is installed in the entire inner part of the experimental setup. The hydraulic gradient is adjustable via a threaded rod with an overflow cup. Microbial contamination can be prevented by darkening the laboratory, temperature control via air conditioning, additional gassing with nitrogen and irradiation of water with UV radiation. Physico-chemical parameters (pH, temperature, specific electrical conductivity and redox potential) can be measured using the installed flow cell.

      Understanding Uranium and Arsenic sources and mobility in deep groundwater flow systems from the Altiplano Mexicano (San Luis Potosi and Zacatecas states)

      Funding: Conacyt

      On the Mexican Altiplano with its semi-arid to arid climate and due to its geological condition with igneous rocks and related sediments, which have elevated concentrations of uranium and arsenic, these two trace elements show a relationship, despite their generally different redox properties and transport behavior. Therefore, these elements can be mobilized into groundwater, which is the main source for water supply of the population in these areas. There is a need to understand the processes of geogenic enrichment of uranium and arsenic in the sediments and their release to the groundwater. Therefore, the objective of the study is to understand processes controlling uranium and arsenic mobility in groundwater based on geochemical, hydrogeochemical and mineralogical characterization. Also to quantitatively support, the conceptual model of the transport of uranium and arsenic in the Calera and Villa de Reyes basins.

      (Deutsch) Erfassung tiefer Grundwasserströmungssysteme als Beitrag zu einer nachhaltigen Nutzung der Wasserressource auf dem mexikanischen Altiplano

      Funding: DLR

      (Deutsch) Zwei Sedimentbecken im Mexikanischen Altiplano wurden hinsichtlich ihres hydrogeologischen Aufbaus und ihrer Fließprozesse untersucht: das Becken von San Luis Potosí (Bundesstaat San Luis Potosí) und das Calera-Benito Juárez Becken (Bundesstaat Zacatecas).
