Weathering is a fundamental process that controls the development of Earth's surface by the formation of erodible material and the release of mineral-bound nutrients. Weathering at depth has been predominantly studied in humid environments, where fluid flow sets mineralogical transformations, whereas (semi-)arid regions were barely investigated in...
Identification and location of contamination sources is crucial for water resource
protection — especially in karst aquifers which provide 25% of the world´s population
with water but are highly vulnerable to contamination. Transport-based source tracking
is proposed and verified here as a complementary approach to microbial and chemical
source tra...
Experimental re-examination of the heterotype solid solution between calcite and strontianite and Ca-Sr fluid-carbonate distribution
We investigated emerald, the bright-green gem varietal of beryl, from a new locality at Kruta Balka, Ukraine and compare its chemical characteristics with those of emerald from selected occurrences worldwide (Austria, Australia, Colombia, South Africa, Russia) in order to clarify the types and amounts of substitutions as well as the factors control...

TINOPAL CBS–X has been described in published literature as a fluorescent dye that is suitable for use as a tracer in groundwater investigations. However, several of these field tests have yielded unexpected results. In this study the influence that the complexation agent EDTA (ethylenediaminetetraacetate) and pH have on the solubility of TINOPAL C...
Karst aquifers are known to be prone to a variety of different types of contamination from a range of different sources. Due to the rapid recharge and high transport velocities associated with karst aquifers, karst springs usually show high discharge dynamics, and water quality often deteriorates very quickly following storm events due to the prese...
A significant proportion of the global water supply is ensured by karst aquifers. However, these are often highly vulnerable to contamination. A storm water tank located in the rural karst catchment area of the Gallusquelle spring (Swabian Alb, southwest Germany) about 9.1 km away was identified as a potential source of contamination. A tracer expe...
Although karst aquifers are far more susceptible to contamination than porous aquifers, with the transport of particulate matter being an important factor, little is known about the attenuation of solutes within karst aquifers and even less about the attenuation of particulate matter. These in-situ investigations have therefore aimed to systematica...
The identification and differentiation of different sources of contamination are crucial aspects of risk assessment in water resource protection. This is especially challenging in karst environments due to their highly heterogeneous flow fields. We have investigated the use of two artificial sweeteners, cyclamate and acesulfame, as an indicator set...
Karst aquifers are known to be highly vulnerable to contamination due to their particular hydraulic characteristics. A number of parameters (such as turbidity, dissolved organic matter concentration, particle size distribution) have been proposed as proxies that can be used to detect changes in water quality or contamination of karst springs. Howev...
Recharge events in karst catchments are often accompanied by rapid changes of electrical conductivity, temperature or turbidity in associated karst springs. Turbidity is usually used as a proxy for suspended matter. However, it is not capable to characterize suspended matter in detail as it lumps signals of particles of a wide range of sizes. Chang...
The main objectives of this study were to evaluate the effectiveness of using iron impregnated granular activated carbon (AC) to remove arsenic from water and to assess the partitioning behavior of arsenic under a variety of conditions. Iron impregnated granular activated carbon (AC-Fe) composites were prepared with different ferric (Fe +3) concent...
The main idea of this study is to combine adsorption active sites of iron(hydr)oxide with high specific surface area and better mechanical resistance of activated carbon, so that the composite can be used efficiently as a filter media for arsenic removal from drinking water. The objective of this study is to evaluate the arsenic removal efficiency...
The substantial transformation of the angiotensin II receptor antagonist valsartan to the transformation product 2'-(2H-tetrazol-5-yl)-[1,1'-biphenyl]-4-carboxylic acid (referred to as valsartan acid) during the activated sludge process was demonstrated in the literature and confirmed in the here presented study. However, there was a severe lack of...
The studied karst spring 'Gallusquelle' is located on the Swabian Alb in
Southwest Germany. The catchment area of the 'Gallusquelle' measures
about 45 km². An average annual discharge of 0.5 m³/s serves
drinking water to about 40,000 people via a waterworks. The study is
part of the research project 'AGRO' (www.projekt-agro.de). The main
objective...
The main focus of the AGRO research project is on the use of various
micropollutants as indicators (e.g. for wastewater) in the catchment of
the karst spring Gallusquelle, Swabian Alb. For modeling the
micropollutants' fate in the subsurface and their occurrence in spring
water, reliable estimates of the spatio-temporal input, i.e. input
functions,...

Wir suchen eine/n wiss. Mitarbeiter/in für ein 3-jähriges BMBF-Projekt (GEO:N – Geoforschung für Nachhaltigkeit), das sich mit dem nachhaltigen Betrieb von Anlagen zur thermischen Energiespeicherung in Aquiferen befasst (Aquifer Thermal Energy Systems – ATES). Das Projekt wird im Verbund mit dem Helmholtz-Zentrum Potsdam (Deutsches GeoForschungsZentrum) und der TU Bergakademie Freiberg durchgeführt.
Das primäre Ziel des interdisziplinär angelegten Forschungsvorhabens UnClog-ATES ist es ein umfassendes Verständnis über die Clogging- und Scalingprozesse in ATES-Systemen zu erlangen und deren Auswirkungen auf die Schadstoffdynamik aufzuzeigen. Damit soll erreicht werden, dass ATES-Systeme in Zukunft effizient eingesetzt und sicher betrieben werden können.
Die ausgeschriebene Stelle ist verantwortlich für die reaktive Stofftransportmodellierung anhand von Daten aus 1D-Säulenexperimenten. Der Fokus liegt dabei auf den Lösungs- und Wiederausfällungsprozessen von Karbonaten und Eisen(hydr)oxiden im siliziklastischen Aquifer, sowie auf die begleitende Mobilisierung/Fixierung von Schwermetallen. Basierend auf den Ergebnissen sollen 2D/3D-Prognosen zum Reservoirverhalten von potentiellen ATES-Standorten getroffen werden.
Der/die Stelleninhaber/in soll das Projektmanagement und die Wissenskommunikation unterstützen. Das Einwerben von Drittmitteln wird begrüßt und unterstützt.
Die Stelle wird zusammen mit einer weiteren Stelle besetzt, die zur Aufgabe hat, experimentelle Daten aus Säulenversuchen zu gewinnen, und diese für den Einsatz in der Modellierung aufzuarbeiten.

Groundwater quality is widely compromised by anthropogenic impact. This becomes evident by the presence of numerous anthropogenic organic and inorganic contaminants in groundwater. Contaminants are of widespread origin. They enter the groundwater associated to different processes such as sewer failure, agricultural activities or contaminated industrial sites.
Understanding the input mechanism, transport, attenuation and degradation processes in short and long term is crucial for sustainable groundwater development.
Although unwanted, contaminants even in smallest quantities might provide information for locating their input or allow for understanding transport and attenuation processes within aquifers. In addition, microbial communities might not only be harmful but assist in the degradation of harmful substances.
We call for contributions that deal with groundwater quality in all type of aquifers (e.g. alluvial, fractured, and karst aquifers). We welcome topics such as urban groundwater, new tools for water quality characterization, organic micropollutants in groundwater, microbial contaminants (such as bacteria, virus, and protozoans), groundwater remediation, and water quality monitoring.
