In the framework of the Czech-German bilateral project 'Humine Substances in the Ore Mountains', aimed at the issue of occurrence, causes and consequences of increased contents of humine substances in water-supply reservoirs in the Ore Mountains, starting in June 2001 concentrations of 18 basic chemical parameters in waters of the catchment area of the Fláje reservoir have regularly been monitored at one-month intervals.
In the tributaries of the reservoir, there have been found relatively high concentrations of DOC, aluminium and iron, owing to the occurrence of humine substances, which fluctuated considerably during the period of monitoring.
However, in the reservoir itself a significant reduction of these concentration fluctuations comes about.
To identify, in more detail, the composition of the present organic carbon, the technique of gel chromatography with an OC detector has been applied.
The results of this monitoring have so far shown a high share of humine substances amounting to 60-80 %, as well as the presence of other groups of substances, such as polysaccharides, building blocks, amphiphilic substances, and some others.
In the process of treating water from the Fláje reservoir, especially the fractions of bigger molecular size are being removed.
