摘要：The paper presents the water classification of four small
retention reservoirs on the basis of selected physical and chemical
indicators, such as: conductivity, pH level, dissolved oxygen, calcium
hardness, general hardness and alkalinity. Three reservoirs (Ożanna,
Kamionka and Cierpisz) are within the limits in terms of average values for
the second class of water quality. Water in the Nowa Wieś reservoir does
not qualify as second quality class of surface water. These reservoirs have
had very irregular seasonal variations of water quality. Unambiguous
correlations have not been established. Aggressive properties of water have
been tested on the basis of Langelier (IL) or Ryznar (IR) indexes and
calcium carbonate saturation [pHs]. Waters in the Ożanna and Nowa Wieś
reservoirs do not have aggressive properties. Both the Kamionka and
Cierpisz reservoirs are characterized by corrosive and leaching
aggressiveness.
