Students from Da Vinci Primary and High School visited our analytical laboratories to learn more about water analyses. They applied the knowledge later during their field expedition to collect a wide variety of water samples, e.g., from streams, ponds, flooded quarries, wells, school drinking water, or swimming pools. Our collaboration continued in the Laboratories of Environmental Geochemistry, where we prepared all the water samples for chemical analyses. The goal of this student research was to monitor selected basic properties of water (pH, electric conductivity, temperature, dissolved oxygen, elemental composition) in the surveyed area. Major and trace elements, organic carbon, nitrates, chlorides, etc. were analysed in our laboratories. The site-related and water type-related changes of the physico-chemical properties were discussed and the concentrations in various water samples were compared with the regulatory limits.
