Standortsuche für Mülldeponien: Mitwirkung der Hydrogeologen an den Wasserwirtschaftsämtern
[Identifying suitable sites for waste dumps: Contributions from Hydrogeological Consultants]

U. Kleeberger


Keywords:
waste disposal, hydrogeology, Bavaria, water managment

Abstract: The procedure for the identification of suitable sites for waste disposal in Bavaria is presented. The contribution of hydrogeologists and of administrative bodies is outlined. Using examples from the regions of Nürnberg and Erlangen/Höchstadt actual problems that may occur during this process are discussed.

Grundwassereinzugsgebiet und Trinkwasserschutzgebiet
[Groundwater catchments and protection zones for drinking water]

G. Koschel


Keywords:
protection zones, groundwater catchments, drinking water

Abstract: In Bavaria the protection of groundwater is guaranteed through several federal laws and bavarian laws. In addition groundwater protection has become a major political topic. However, the application of these laws has not always been sufficient resulting in longterm pollution of groundwaters with nitrate and pesticides. Remediation measures often aim at improving the protection of groundwater catchments. Still, this can not replace the remediation of all the major groundwater pollution sources in Bavaria. Even a well implemented strategy of groundwater protection can not exclude pollution riscs in certain very sensitive parts of the groundwater catchment. This requires specific regulations, which have to be defined on the ground of hydrogeological information and expertise. Requirements and forms for the implementation of protection zones for spas.

Anforderungen an die Antragsunterlagen zur Ausweisung von Heilquellenschutzgebieten
[Requirements and forms for the implementation of protection zones]

B. Pitschka


Keywords:
Spa, protection zones

Abstract: The specific conditions for the use of spas (for medicinal purposes poses ) require higher standards for the implementation of protection zones. Usually, the administritative procedure is based on the WPBV regulation, which, however, is not sufficient for spa protection zones. In addition, the necessary expertise needs to be clear and sound. The VwvBayWg, A. 40.1.3) regulation is recommended as a guideline.

Der Einfluß intensiver Landwirtschaft auf das Grundwasser am Beispiel der Bugquelle bei Homburg a. Main - natürliche Voraussetzungen, Sanierungskonzept
[Influence of Intensive Agricultural Use on the Ground-Water Exxamplified by the Bugquelle Near Homburg/Main - Natural Preconditions, Concept of Sanitation]

W. Schneider


Keywords:
nitrogen concentration, Muschelkalk, reducing of nitrogen

Abstract: The Bugquelle near Homburg/Main with a potential groundwater yield of more than 1.0 Mio. m3/a represents a groundwater resource of regional importance. For over 15 years the spring has shown elevated nitrogen concentrations almost always exceeding the critical value of the german Trinkwasserverordnung. The catchment area consists of a carst aquifer in the Muschelkalk. Analysis of the drainage volume and the nitrogen concentration indicate a close relationship between those two factors of the spring. Heavy precipitation causes a nitrogen transport into deeper parts of the groundwater. According to analysis of the soil profiles, transport velocities are high in most parts of the catchment area. Nitrogen transportation may only be managed by reducing the nitrogen input. In order to controll the nitrogen transport within water conservation zones of the catchment area, a 10-20% reduction in nitrogen fertilization of sensitive soils by the farming industries is requested. Two examples of resulting compensation payments and effects on water prices are given.

Neufassung der Richtlinien für Heilquellenschutzgebiete durch die LAWA
[Revised version of the guidelines of protection zones of spas by the LAWA]

W. Wenger


Keywords:
spa, protection zone

Abstract: At the moment the guidelines of protection zones for spas are reorganized by an ad-hoc working group of the LAWA organisation (Länderarbeitsgemeinschaft Wasser) and adapted to the reformed presupposition of environment law and to the new scientific knowledge. Based on a hydrogeological standardization of the spas the requirement of the spa protection is more differentiated with respect to the protection potential of the subsoil than it was before.

Umweltschonende Landbewirtschaftung zum Schutz mittelfränkischer Trinkwasservorräte, Rahmenkonzept
[Ecological agriculture for the protection of the middle franconian drinking water resources, a framework]

A. Bock


Keywords:
Nitrate, drinking water, Middle Franconia, fertilizers

Abstract: Problems with high nitrate concentrations in the groundwater in Middle Franconia requires specific measures for the protection of groundwater resources. A framework outlines a close and free cooperation between farmers and water supply institutions. It is supposed to make the work of the administrative bodies involved and of water supply institutions easier. Due to changing site specific factors this framework has to be adapted from case to case.

Leukämie- und Lymphom- Nester: Besteht ein hydrogeologischer Einfluß?
[Leukemia and cancer: Is there a hydrogeological influence?]

F. Curio


Keywords:
leukemia, cancer, hydrogeology

Abstract: In the last forty years the observation has been made that leukemia and related cancers have been concentrated in well defined areas of 75-100 m diameter. These areas are characterized by a hydrogeological similarity: they are located close to (ancient) wetlands, swamps or rivers.

Zur Berücksichtigung der Dispersion bei der Ausweisung von Wasserschutzgebieten
[Notes on the Use of Dispersion for Planning Protection Zones of Water Catchments]

A. E. Jakowski


Keywords:
Dispersion, Karst Aquifer, Joint Aquifer, Protection Zones for Water Catchments, Baden - Wuerttemberg

Abstract: The results of more than hundred tracer tests carried out in different karst and joint aquifers in Baden-Württemberg, Germany, offer a large amount of data sets for comparing geohydraulic parameters. The results demonstrate the role of dispersion in the hydraulics of karst and joint aquifers. Applied hydrogeological studies show how the dispersion can be used for identifying protection zones for groundwater catchments.

Energetische und balneologische Anwendungen der Geothermie
[Application of geothermal energy for balneology and energy production]

J. Ruhland


Keywords:
geothermal energy, balneology

Abstract: The use of geothermal energy as a 'clean' and ecologically acceptable resource becomes a topic of increasing interest. However, the geological situation of the potential site limits the economic feasibility for its exploitation.

Nachweis von Oberflächenwassereinfluß im Grundwasser mittels gewässerbiologischer Indikatoren
[Detection of stream-aquifer interactions using microbiological indicators]

W.-D. Schmidt


Keywords:
stream-aquifer interactions, microbiological indicators

Abstract: Site specific endemic microorganisms can be used to study stream-aquifer interactions. This method allows to investigate the degree of strain infiltration into adjacent aquifers and to estimate the residence time of infiltrated water. Although this approach can be used for quick routine analysis it is not often applied.
