Hydrochemical and hydrogeological assessment of spring waters in the western Lusatian Mountains and Zittau Basin
Palkovičová, Veronika ; Komínková, Dana (advisor) ; Kamil, Kamil (referee)
The bachelor thesis was conducted within the project "Springs connect landscapes and countries - environmental education and cooperation in the Liberec - Zittau region". The studied area is located along border of the Czech Republic and the Federal Republic of Germany, in the region of the former Sudetenland. The area encompasses two sea drainage basins and four geological units, resulting in a diverse landscape morpholgy with various types of groundwater.
From March until December 2016, field measurements and water sampling were carried out on selected springs in the western part of the Liberec - Zittau region. Basic physical-chemical parametres (temperature, pH-value, electrical conductivity, redox-potential, dissolved oxygen and, if possible, discharge) were determinee on the field. Water samples were collected and processed in the laboratory. Concentrations of most anions (SO42-, Cl-, NO3-, PO43-, ...) were measured by Ion Chromatograph (Dionex ICS-1100). Cations (Ca2+, Na+, Mg2+, Fe3+, Al3+, K+, ...) were measured by inductively coupled plasma with optical emission or mass spectrometry (ICP-OES, ICP-MS), depending on the expected concentration.
The measured data was averaged and sorted into four geological categories according to the geological map (crystalline complex, cretaceous, quaternary sediments, volcanites). Data were further evaluated using the demo version of the commercially available AquaChem hydrochemical software (Piper and Stiff diagram) as well as in the statistical program R. The average concentrations in most springs confirmed the attribution to the particular geological settings, however, some springs reveal a significant affect by agricultural activity. From the graphical representation of the concentration of selected ions in the spring water, it is also evident that the Quaternary sediments of the Zittau basin were likely formed from the surrounding crystalline.
