“…Several studies on groundwater fauna in porous aquifers and surface-groundwater interaction were conducted in the last few years in Germany (e.g. Matzke et al 2004;Berkhoff et al 2009;Brielmann et al 2011;Gutjahr et al 2013). In Austria, groundwater fauna research is currently restricted to a few study areas in caves and porous aquifers.…”

Extensive in-depth research is required for the implementation of natural tracer approaches to hydrogeological investigation to be feasible in mountainous regions. This review considers the application of hydrochemical and biotic parameters in mountain regions over the past few decades with particular reference to the Austrian Alps, as an example for alpine-type mountain belts. A brief introduction to Austria's hydrogeological arrangement is given to show the significance of fractured hard-rock aquifers for hydrogeological science as well as for water supply purposes. A literature search showed that research concerning fractured hard-rock aquifers in Austria is clearly underrepresented to date, especially when taking the abundance of this aquifer type and the significance of this topic into consideration. The application of abiotic natural tracers (hydrochemical and isotope parameters) is discussed generally and by means of examples from the Austrian Alps. The potential of biotic tracers (microbiota and meiofauna) is elucidated. It is shown that the meiofauna approach to investigating fractured aquifers has not yet been applied in the reviewed region, nor worldwide. Two examples of new approaches in mountainous fractured aquifers are introduced:(1) use of CO 2 partial pressure and calcite saturation of spring water to reconstruct catchments and flow dynamics (abiotic approach), and, (2) consideration of hard-rock aquifers as habitats to reconstruct aquifer conditions (biotic approach).

“…The groundwater habitats derived from faunistic data yielded in a five-class system provided valuable information for understanding patterns in the sampled region of the Palatinate, South-Western Germany and allowed the incorporation of former classification approaches. Gutjahr et al (2013b) transferred the findings of this study to another local scale groundwater survey in Baden-Wuerttemberg, South-Western Germany, where four of the five habitats proposed here were identified. While limited to a comparatively moderate dataset from a specific region, we propose that this concept describes general patterns.…”

Distribution of groundwater invertebrate communities in porous aquifers (and their habitats) varies on spatial scales and many attempts have been made to classify these on various scales. The new data-based approach, presented here, classifies the complex distribution of groundwater habitats on a local scale (i.e. along transects of < 100 m) and merges the latest classification approaches at this scale. Data from a regional (i.e. approximately 100 km 2) biogeographic groundwater survey was analysed in terms of stability of: community structure, different intensities of surface water influence, and occurrence, together with the distribution of stygobites within those groundwater ecosystems. On the investigated local scale, the faunistic communities' composition is mainly depending on surface water influence, coupled with immi-sion of dissolved oxygen and organic matter. Derived from this finding, five types of faunistic habitats are proposed: (I) Stressed groundwater habitats, (II) Stable groundwater habitats, (III) Rain fed groundwater habitats , (IV) Surface water fed groundwater habitats, and (V) Hyporheic habitats.

“…In Europe, groundwater quality is still evaluated based on physical, chemical and hydrological characteristics (European Commission, 2006), although the inclusion of ecological criteria has been repeatedly advocated (Danielopol et al, 2004(Danielopol et al, , 2006b(Danielopol et al, , 2008Hancock et al, 2005;Hahn, 2006;Tomlinson et al, 2007;Steube et al, 2009;Griebler et al, 2010). The few existing ecological indicators of groundwater ecosystem health consist of the examination of parameters describing invertebrate or microbial communities (Mösslacher, 2000;Danielopol et al, 2006a;Hahn, 2006;Gutjard et al, 2013;Griebler et al, 2010;Stein et al, 2010;Korbel & Hose, 2011;Gutjahr, 2013;Griebler et al, 2014) or biofilm growing on artificial substrates (Williamson et al, 2012;Mermillod-Blondin et al, 2013). More recently, the use of sentinel invertebrates caged inside groundwater wells has been proposed to avoid confounding effects related to local characteristics (e.g.…”

Ecology-based evaluation of groundwater ecosystems under intensive agriculture: A combination of community analysis and sentinel exposure

Ecological criteria are needed for a comprehensive evaluation of groundwater ecosystem health by including biological components with the physical and chemical properties that are already required by European directives. Two methodological approaches to assess the ecological status of groundwater ecosystems were combined in two alluvial plains (the Ariège and Hers Rivers, southwestern France) varying in agriculture intensity (from grassland to crop rotation including maize and sunflower, and to maize monoculture). In the first approach, the composition of invertebrate assemblages (only obligate-groundwater crustaceans, i.e. stygobionts) sampled in 28 wells differing in their land use contexts was analysed. Abundance, species richness, and assemblage composition significantly changed with agricultural land use or urbanization around the wells. In the second approach, we tested an in situ exposure of sentinel organisms to quantify their response to the environmental pressures. The epigean and native amphipod species Gammarus cf. orinos was used as the sentinel species. Amphipods (30 individuals in each of 10 wells) were exposed for one week to the in situ conditions at two seasons with contrasted concentrations of pollutants. The Ecophysiological Index (EPI) synthetizing the survival rates and energetic storage decreased in wells with low oxygen and high nitrate concentrations, but only during the highest contamination period. Atrazine-related compounds negatively impacted sentinel health whatever the season. The combination of these two approaches may have major applications for orientating groundwater ecosystem management.
