Article
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...
Article
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...

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...

Article
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...
Article
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...
Article
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...
Article
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...
Article
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...
Conference Paper
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...
Article
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...
Conference Paper
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...
Article
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.

https://www.geokarlsruhe2021.de/#sessions Tobias Licha1, Ferry Schiperski2 1Ruhr-Universität Bochum; 2TU Berlin, Germany Keynote: Mario Schirmer, EAWAG, Switzrland 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.
