Podmienky na absolvovanie predmetu (Grading policy):
Grades will be based on a final oral examination (contributing 75%) and a written evaluation of a practical task (25%). The course has a standardized grading system which is identified below:
A (91–100%): Outstanding, excellent work (exceptional performance with strong evidence of original thinking and an obvious capacity to analyse, synthesize and evaluate. B (81–90 %): Good, competent work; laudable performance with evidence of some original thinking, good problem-solving ability, exhibiting a serious, responsible engagement with the course content. C (73–80): Adequate, reasonably satisfactory work; fair performance but infrequent evidence of original thinking or the capacity to analyse, satisfies the minimum requirements of the course. D (66–72%): Less acceptable work; relatively weak performance with little evidence of original thinking or ability to analyse or synthesize course material.  E (60–65%): Minimally acceptable work; very weak performance with little evidence of original thinking, showing an inadequate grasp of some basic elements of the course. Fx (under 60%): Inadequate work; poor performance which indicates a lack of understanding or misunderstanding of essential subject matter.	
Výsledky vzdelávania (Course objectives):  
This course covers the background and skills needed to understand basic chemical, physico-chemical and geochemical processes influencing the chemical composition of natural waters. By the end of this course, students should be able to:
•	identify the basic genetic types of water and understand which processes are forming their composition..
•	understand the processes of rock – water and gas phase – water interactions.
       identify the origin of main anthropogenic, as well as natural chemical components in natural water
•	understand the fate and transport of pollutants in natural waters
•	Apply basic methods of water analyses evaluation
