“…Results from previous faunistic groundwater analyses are contained in a Germany-wide data record (data record by Hahn, 2005;Berkhoff, 2010;Stein et al, 2012;Gutjahr, 2013;Spengler, 2017;Spengler and Hahn, 2018). A closer look at the southwestern part of Germany, the German federal state Baden-Württemberg, is given by Hahn and Fuchs (2009).…”

“…used the GFI as part of a proposal for a groundwater habitat classification at local scale, which introduce five types of faunistic habitats as a result of surface water influence, content of dissolved oxygen and amount of organic matter. Moreover, in the study of Berkhoff (2010) the GFI was used to examine the impact of the surface water influence on groundwater with the aim to develop a faunistic monitoring concept for hydrological exchange processes in the surrounding of waterside filtration plants. Spengler and Hahn (2018) argued for the definition of a regional and ecological temperature threshold and an ecology based assessment of thermal stress in groundwater.…”

Abstract. In Germany 70 % of the drinking water demand is met by groundwater, whose quality is the product of manifold physical-chemical and biological cleaning processes. As healthy groundwater ecosystems help to provide clean drinking water, it is necessary to assess the ecological conditions of these ecosystems. This is particularly true for densely populated, urban areas, where faunistic groundwater investigations are still scare. The aim of this study is therefore to provide a first-tier assessment of the groundwater fauna in an urban area. Thus, we assess the ecological condition of an anthropogenically influenced aquifer by analysing the groundwater fauna in 39 groundwater monitoring wells in Karlsruhe (Germany) and a nearby forest land. For classification we apply the scheme from the Federal Environmental Agency (UBA), in which a threshold of more than 70 % of Crustaceans and of less than 20 % of Oligochaetes serves as an indication for good ecological conditions. In our study 35 % of the wells in the urban area fulfil these criteria, and even in the pristine forest land only 50 % of the wells indicate fine ecological conditions. While the assessment reveals that ecological conditions in the studied urban area are predominantly not in a good ecological state, there is no clear spatial pattern with respect to land use and anthropogenic impacts. However, there are noticeable differences in the spatial distribution of species and abiotic groundwater characteristics between wells in forest land and the urban area, which indicates that more comprehensive assessment methods are required to fully capture the different effects on groundwater fauna.

About faunal life in Austrian aquifers – historical background and current developments

In Austria all general types of aquifers (porous, karstic and fractured) are present and are subject of hydraulic and hydrochemical investigations. However, in hydrogeological research it is a still widely neglected fact that groundwater flow is not only a flux of water, chemicals and heat within lithological units but that groundwater bodies may also act as habitats with very particular conditions for their inhabitants. In general groundwater inhabitants require three things: a place to live, oxygen and energy or food, respectively. Thus, the living conditions of groundwater animals are directly connected to hydrological and geomorphological conditions on a regional scale, and on a local scale, lithological and structural properties that control hydrogeological parameters such as porosity and hydraulic conductivity, recharge mechanisms and flow dynamics.In this paper we view Austrian hydrogeology from the perspective of groundwater fauna in order to elucidate the connection between the hydrogeological conditions and biological patterns. A brief review of groundwater biology research in general and specifically in Austria, revealed that crustaceans are basically in the focus of groundwater research while other common groundwater dwellers, such as free-living nematodes, are less studied similarly. Porous aquifers are comparably well investigated by groundwater biologists, while fractured aquifers have rarely been considered as habitats to date.Due to the complex hydrogeological situation in Austria, with a greater portion of fractured and karstic aquifers, a systematic biological survey considering hydrogeological aspects may lead to a pronounced progress for the both disciplines, hydrogeology and groundwater biology. For hydrogeological purposes, the studies may provide the basis for using groundwater species (similar to the established method of using stable isotopes) as natural tracers in future studies. From the biological perspective, progress in the understanding of complex habitat-biota relations is expected to result from the investigation of hitherto unknown habitats. In addition, such a survey would not only be an important contribution to biodiversity and biogeography in Austria, it would also promote groundwater research in a broader context, such as the need to protect groundwater as a valuable service providing system (e.g. water quality).Preliminary results from six test sites distributed to four different geological settings (Quaternary basin fill, Flysch-Zone, Northern Calcareous Alps and the Central Crystalline Zone within the Alps) show evidence for a link between the hydrogeological conditions and the present biological assemblages. However, a systematic survey is still required to understand which environmental factors mainly govern live in Austrian aquifers.

“…The biological stability of drinking water describes the processes that occur in distribution networks and impact drinking water quality; accordingly, the goal of biological stability is minimum change in water quality during transport processes within distribution Groundwater used as drinking water generally possesses low levels of nutrients; however, some groundwater inhabitants are only occasionally flushed out into drinking water treatment systems, after which they can migrate into drinking water distribution systems. These groundwater organisms are characterized by high sensitivity to water heating, are adapted to low nutrient levels and have small growth rates [16,17]. Thus, drinking water quality problems associated with such organisms are rare.…”

Activities to ensure and maintain water quality in drinking water networks, including flushing, are presented after standardized hydrant sampling combined with a stainless-steel low pressure–high flow rate (NDHF) filter and a 100 µm mesh size was used to separate pipe inhabitants. A databank of more than 1000 hydrant samples in European lowland areas was developed and used to analyze the diversity and abundance of macroinvertebrates in drinking water networks. Load classes for water louse (Asellus aquaticus) and oligochaetes are given with three evaluation classes: normal colonization, increased colonization, and mass development. The response of Asellus aquaticus in drinking water networks to environmental conditions are presented as are their growth and reproduction, promotion of a third generation by climate change effects, food limitations, and the composition and stability of their feces. Finally, the health risks posed by dead water lice and water lice feces with bacterial regrowth and the promotion of microbe development on house filters are analyzed.
