Vulnerability maps are standard tools for the assessment of groundwater sensitivity to contamination. Due to their increased use in technical guidelines, vulnerability maps have become state-of-the-art tools in resource management. However, most approaches have been developed by hydrogeologists and soil scientists who incorporate the understanding of processes from their specific disciplines very well but have limitations in considering processes in other disciplines. A soil-specific database for vulnerability assessment has been significantly improved by soil scientists over the past several years and includes quality, spatial extension and availability. Hence, it is time to integrate this database into hydrogeological concepts. This work presents a vulnerability mapping approach that considers a new soil database that has been available since 2014 for the entire Baden-Württemberg region at a scale of 1:50.000, adapting the well-established GLA and PI methods. Due to the newly-developed classification scheme for the protective function, this approach provides a more balanced and meaningful classification. This leads to a distinct image of the study area and a better interpretation of vulnerability. © 2014, Springer-Verlag Berlin Heidelberg. Source

The accuracy and reliability of semi-quantitative inductively coupled plasma mass spectrometry (ICP-MS) were evaluated through two certified reference materials and real water samples from the Lake Constance Water Supply. Results for the real water samples measured by semi-quantitative ICP-MS were compared with those analyzed by different quantitative methods. With semi-quantitative ICP-MS it is possible to determine elements not present in the calibration standard. The concentrations of non-calibrated elements might be questionable, but can give a reliable hint for the presence or absence of elements in the sample. The results demonstrate that semi-quantitative ICP-MS is a reliable tool to analyze aqueous samples in emergency situations. © 2013 Springer Science+Business Media New York. Source
